Real men keep their equipment in tip top shape. They know that in order to get the job done, anything less than this creates problems with performance. It's nothing to be ashamed of and can happen to anyone. However, to continue operating your equipment at sub-standard levels is not only detrimental - it can be considered unsafe. Finally help has arrived. If your Rotating Equipment has been making you feel less than adequate, ACQUIP can help.

As you know, as things get heated up and the action gets going, some things become elongated. They grow in diameter and they grow in length. This is a normal and natural law of physics. Some show this more than others, but all deserve and experience their fair share. Depending upon one's level of experience, we understand that this will bring greater friction and stress to the moving parts. This can also result in a certain level of slop or dynamic movement. Although most of us like a tight fit and try to keep slop to a minimum, we realize this is a reality and a fact of life. Those of us that are aware of this and know how to deal with it will not only reach their peak of experience while their Rotating Equipment is in operation, but they will just enjoy using their equipment that much more. That's good for the equipment owner and their partners - whether they be one or many.

Are you measuring and monitoring your Rotating Equipment?

If you are proud of your equipment and want it to last and perform well, then monitoring it is a necessity. To do it right, you need to check its state when it is cool. As you know, it is probably shorter and smaller in diameter at this point. Don't worry, that's normal. But when things get moving, you'll want to measure and monitor. This can even be done safely and effectively by the best in the business using laser-based systems. The data is gathered and sizes, movements and times are all noted. With all this data, you can be sure your system performance can be improved and bring smiles to faces. You'll be more satisfied.

Whether you are in the Oil and Gas Industry, the Electrical Power Industry, the Petroleum or Chemical Industry or any other where your Rotating Equipment undergoes extreme temperatures and solid performance is a must, ACQUIP can help. They can help with your dynamic movement issues as they impact boiler fee pumps. The pumping can continue and the whole experience can be improved.

When coupling the couplings, seals and bearings, you'll want to insure efficiency and experience as little as possible damage. Although the exhaust end is not always the interest when most have their equipment at hand, it is relevant when dealing with gas turbines. The exhaust end needs to have its thermal growth monitored and accounted for when in operation because extreme temperatures will occur there.

In conclusion, we all want our equipment to operate the best it can. There are times when a lot of movement will occur and temperatures will rise. These times you may want to monitor movements and temperatures and ACQUIP can help. Don't be shy to let them help. Whether the size of your operation is big or small, partners many or few, they will act in a professional manner and give you the data to make adjustments to optimize your performance and bring more satisfaction to all.

Dynamic Movement: Temperature Changes Mean More than Hot or Cold

Dynamic movement, which also goes by the name thermal growth, is the change in length of metal that results from temperature change. If a metal bar is heated, it will elongate; it shrinks when cooled. The degree of change is dependent on the extent of temperature change and the individual metal.

The difference in the temperature of a machine during operation, as opposed to off line, will result in thermal growth. Manufacturers as well as engineers in other industries must take this into consider; the effects on a machine are significant to its bearings and supports.

Methods used to determine dynamic movement

Some dynamic movement can be predicted by information previously gathered; to some extent, the known thermal growth for a metal can help with theoretical calculations. Historic information as well as the theoretical calculations when combined determine manufacturer specifications. In addition, hot alignment checks show changes in machine alignment when it has reached its maximum operating temperature.

These methods, while helpful, are not adequate to the task of determining dynamic movement. To find the necessary information, thermal and torsion stresses must be measured while the machine is in operations to find the true dynamic movement within the machine. With measurement of these forces, a plan to compensate for them can be developed.

How dynamic movements are measured

It is vital that monitoring of a machine occurs through all the temperature variations it will undergo. Laser-based systems align coupling targets throughout the thermal range, and data is recorded and time stamped. Accurate alignment targets are designated, and the correlation of alignment changes with unites of time is made possible. 

Who needs to monitor dynamic movement:

• Oil and Gas Industry
  
• Electrical Power Industry
  
• Petroleum/Chemical Industry
  
• Any industry where machinery undergoes temperature extremes

Examples of common machines with dynamic movement issues

Dynamic movement issues are common with Boiler fee pumps and must be measured wherever one is in operation in order to insure efficiency and minimize damage to coupling, seals and bearings. 

Gas turbines especially need measurement of thermal growth due to extreme temperature that are found near their exhaust end. 

Our thermal growth monitoring services facilitate maximum running efficiency and productivity. So, next time when you have any requirement for this service, please contact our offices immediately at 1-855ACQUIP1 or 1-855-227-8471 or by email at info@acquip.com

Turbine Efficiency: Critical For Success

Turbine efficiency controls operating expenses, time management and production. Keeping up with the methods required to ensure maximum efficiency is vital in industries requiring turbine use. 

It's vital for turbine efficiency that maintenance is performed regularly. Maintaining gas and steam turbines includes systematic inspections, this is crucial to catch problems before they occur, or before they become major. Paying attention and being consistent is a major key to increasing the reliability of plant rotating equipment. 

Maintenance includes testing, measuring, adjusting, and replacing parts, intended to prevent faults with turbines. Also important for turbine efficiency is fuel management, with fuel sucking up nearly 75% of most turbine plants budgets. Having a fuel efficient and smooth running system can save considerable money.

Common determining factors to set relevant failure prevention policies are:

• Recommendations from the equipment manufacturer or supplier
• Expert suggestions based on analysis
• Mimicking effective maintenance techniques used on similar equipment
• Evaluating results from measuring value and performance factors

Setting important policies and performing scheduled maintenance is not only important to keeping gas and steam turbines working, but it considerably extends the life of the equipment.

There are several methods for determining proper policy and maintenance requirements. Here are a couple of useful alignment techniques for gas and steam turbines:

Gas Turbine Laser Alignment

Gas turbine laser alignment allows accuracy within one micron. To achieve this accuracy, a laser line is shot through the center of the bearings, shroud, and compressor; this is to create a static point of reference. To maximize efficiency, an adjustable bore bracketing system will then be employed to probe the surfaces of the compressor sections, bearing brackets, and/or shroud. This is done to determine the exact center.

This propriety bracketing can be used while the compressor blades are being installed, or removed. The data received from the internal gas turbine laser alignment is then recorded, and adjusted to meet bearing preset requirements. The appropriate line for the machine is determined, and then executed.

Express Alignment

Express alignment consists of laser alignment readings that are taken for all internal components. The readings are then combined with horizontal joint deviation, as well as out of roundness readings.

An alternative to the tops on/tops off diaphragm alignment for steam turbines is Express Alignment. Readings such as rotor dis-assembly, coupling alignment, and internal component positions are recorded at the original dis-assembly. This method allows the shaft alignment consideration, along with diaphragm alignment at the re-assembly phase. Important information is recorded, such as shell deviations, packing rubs, and diaphragm positions. Theoretical tops on position are then formulated by using the collected data. Only tops off data is required for this method, thus saving money and time required to put on, and take off, the top of the cylinder.

Alignment measurement is an effective resource used by the following types of industries:

• Power Generation
  
• Oil and Gas
  
• Petrochemical Industry
  

Correctly diagnosing alignment issues is a major contributor to improving turbine efficiency. Every method possible to heighten efficiency should be researched and made policy. Incredible amounts of money will be shaved off of operating and manpower costs by keeping highly maintained, efficient turbines.

Rely on emergency laser alignment service for maintaining mission critical assets in top working condition

Preventive maintenance and the regular plant maintenance is an unavoidable necessity for the various industries. Usually, companies try to delay the maintenance in their plants just to save few bucks to improve their bottom line. This normally happen with all those who try to cut corners to save some money in these financially hard times. However, many companies ultimately end up paying huge amounts of money as maintenance cost than those who stick to the rigorous maintenance schedule in their factories. Predictive maintenance permits industries to spend only a fraction of money on the maintenance in the start, than what they would have to spend later on if they delay their maintenance. This usually leads to the significantly big savings for them.

It is for this reason that the number of companies requiring the laser alignment equipment, internal laser alignment turbine services and the laser alignment services on the urgent basis is on rise. It is quite usual for the maintenance teams to undertake “reactive maintenance” steps at the plants, which actually means that a machine will only be repaired when the situation so arises. Such repairs usually result in the abrupt disruption in the plant operation thereby triggering a cascading effect resulting in the drastic drop in the overall production.

Any mission critical assets that go down may need emergency laser alignment so as to enable the machinery to be up again within a minimal time. In all such situations, ACQUIP, INC immediately comes into picture with their team of experienced professionals ready to immediately reach the trouble spot to solve the problem within no time.

The Electronic Radial Alignment Gauge (ERAG) or Concentricity Alignment Tool (CAT)

An ERAG or CAT is not exactly an item that people commonly know the use for. In a nutshell, it is used to measure the distance between two surfaces that are adjacent to each other. The ERAG ensures that the distance measured is accurate. There are an enormous amount of benefits and possibilities to using such equipment.

First of all, the use of tight wire or laser alignment is not necessary. The convenience of this makes the ERAG very easy to use. The advanced rotor accounts for the amount of diaphragm misalignment. The accuracy is outstanding with its resolution at .0001 inch, it can measure distances to a maximum plus/minus ratio of .0005 of an inch. This is because intense field testing and extensive expert developmental implementation has been ongoing since 1992.

The ERAG is extremely durable and can be used thousands of times, year after year without any maintenance. In fact, the requirement for any kind of maintenance or parts replacement is extremely rare. If in such a circumstance that it requires maintaining, parts are readily available at the factory. What's more, most maintenance can be done in the field.

Equipped with an LCD display, you can observe annular space variations in real-time as the CAT is pulled through the packing groove. This happens because the head of the CAT contains a lever that moves along the contour of the diaphragm ID. As it does this, it sends data of the dimensional variations to the display.

On the head of the main body of the instrument there is a pivotally coupled U frame. The arms of this part work in correspondence. They are pivoted in opposite directions and the arms are provided with contact points. The base underneath the U frame is spring loaded so that it can slide within the body of the instrument. The body of the instrument is connected to a transducer.

To accomplish alignment, you can directly measure the dimension of the rotor to seal carrier by having the rotor in place.

Considering how inexpensive the ERAG is, using the equipment in one outing, usually pays for itself. Using the ERAG is easy. It is also one of the best alignment methods to measure the distance between two adjacent surfaces with precision every time!

Two Chief Items India Faces -- Lessening Climate Alterations and Securing Varied Supplies of Energy

The Indian energy usage has been rising at one of the steadfast rates in the globe because of the populace progression and commercial increase. The majority of India’s power derives from oil, natural gas and coal. While the nation remains at a steady development rate, so does India’s energy business, which is searching for energy alternatives, for example, nuclear energy.

India’s Energy Alternatives

Throughout the forthcoming eras, two of India’s biggest tests will be how to advance whilst simultaneously joining a universal drive toward lessening climate alterations and how to secure varied supplies of energy. The dissertation on India’s power security has balanced on the nation’s longing for trade in oil. Thus, India’s chief energy resource is not oil; however a chiefly domestic supply – coal. India and its fast advancing economy assure a shrill rise in energy need.

Consequently, coal is the most-contaminating fossil energy. However, safeguarding security for India should not procure a silver bullet, so to speak. Progressing past unequal coal consumption will necessitate gradual change, baby steps, by using a total of diverse tactics.

An Unexpected Indian Energy Industry Deficiency

India’s coal supplies are not as huge as formerly believed. At the present-day rate, India’s resources would exhaust within eighty years. At the expected rate of development in creation, that amount converts to forty. Moving coal is burdensome and unproductive. The majority of the domestic supplies are condensed in India’s central and eastern territories, distant from the inner-city cores most in want of improved energy.

It could take several years to develop clean coal skills. There are not even remotely enough private outlays in clean-coal equipment. Today, the cost for just one ton of CSS-CO2 is at thirty dollars. R&D prices are elevated as well and each investor appears to be more concerned with short-term aspects, renewable methods. Thus, no current energy plant, globally, uses CCS.

India’s Energy Alternatives – Nuclear as One

Since the coal construction in India, currently, is at a maintainable stage for just 20-30 years more, practical alternatives have to be created and introduced to the marketplace. Nuclear energy is a minimal-carbon power resource. Therefore, that means that the contamination issues curtailing from production are lower; rather, its ecological prices turn up at the rear end of the manufacturing sequence in the storing waste concerning nuclear usage, a touchy governmental topic for discussion.

Currently, nuclear energy represents around 2% of the power production in India. Their government intends to increase nuclear power’s involvements to around 5% by the time the year 2020 arrives and India’s governmental agencies intend to originate 25% of the complete power from nuclear sources by the time the year 2050 arrives. These objectives coincide with India’s goals to lessen climate alteration and securing varied supplies of energy, and they have made it their sole ambition to accomplish these goals, particularly in the commerce segment that has typically fell behind the agency’s development objectives. The United States and India’s agreement political and public nuclear collaboration helps each segment reach the objectives. Logically, though, a noteworthy rise in nuclear energy is a longer-range goal rather than a shorter one.

Making an Investment in Proficiency

Energy forecasters agree that the greatest proficient manner of expanding India’s power supply usage is to enhance proficiency. The Indian governmental department spokespeople have projected that as much as 30/50% of the power produced in their country might be lost alongside the distribution chain. Improved upkeep and updating of cooling equipment would considerably lower the quantity of energy required to produce electricity.

Plant Maintenance staffs must service and maintain their machinery to make sure that their equipment is running proficiently.  Maintenance on gas turbines and steam turbines is necessary to keeping them running in satisfactory operating condition.

Plant Maintenance must provide for systematic inspection, detection, and correction of failures either before they occur or before they develop into major defects. It is vital to pay close attention to these issues to increase reliability for plant rotating equipment.

Maintenance (including tests, measurements, adjustments, and parts replacement) is performed specifically to prevent faults from occurring to gas turbines and steam turbines.

Preventive maintenance for gas turbines and steam turbines are considered to be worthwhile. There are risks such as human error involved when performing preventive maintenance.  This is why you need to make sure you are employing a well trained expert maintenance staff for your gas turbine and steam turbine preventative maintenance measures. It is important to contract out your gas turbine and steam turbine projects to experts that utilize the latest technology for gas turbine and steam turbine maintenance.

Preventive maintenance such as scheduled gas turbine and steam turbine overhaul or scheduled replacement for your gas turbine or steam turbine, provides proactive failure management policies available to the maintenance engineer.

Common methods of determining what preventive failure management policies should be applied to gas turbines and steam turbines are:

• OEM recommendations
• What an “expert” thinks ought to be done.
• The maintenance that’s already done to similar equipment.
• Measured values and performance indications.

To make it simple:

Preventive maintenance is conducted to keep gas turbines and steam turbines working and/or extend the life of the equipment.

ACQUIP, INC is the expert when it comes to providing alignment services for your turbo machinery. We are the experts at providing laser alignment services for gas and steam turbines of any size.

Preventative maintenance can be looked at as a large upfront expense or an unnecessary expense.  This can be a very expensive mistake.   Corrective maintenance can end up costing much more.  Unplanned maintenance also requires unplanned gas turbine and steam turbine shut downs to get equipment working again.

The ACQUIP, INC internal gas and steam turbine laser alignment service is an ideal alignment process for saving time and money!

Conclusion – India’s Goals to Lessen Global Alterations and Secure Varied Supplies of Energy

The US and India have the same objectives. The economy in India developed at a higher level than 9% annually for the past three years prior to the monetary catastrophe they encountered. Its development phase has reduced to a projected 6% in 2009; however, it rose again in 2010 and it is anticipated that it will continue to rise at a steady rate. Even though these lower rates of growth occur, India and its energy usage are certain to increase.

India plans to continue searching for energy alternatives because of its decreasing coal resources and its absence of native oil supplies. Thus, searching for alternatives for power is not sufficient. India has to continue to create new and innovative equipment and knowledge. The newly generated US/India STEF (Science and Technological Endowment Fund) would be a practical tool for quickening the required technological production. Allocating technologies will assist India with accomplishing their goals of lessening global alterations and securing varied supplies of energy.

As the economies of China and India continue to grow at a rapid pace, energy and resource related businesses in Asia are becoming dominant on the world stage. While that means there is great potential for energy and resource providers around the globe, it also has an effect on geopolitical relations. For the past half century, the Western World has been the main consumer of energy and valuable resources. Without substantial competition, Western economies attained all their resource demands, at affordable prices as well.

Today, countries like India and China are quickly becoming modernized, and their industries are beginning to thrive and grow. For them to continue expanding in manufacturing, infrastructure and quality of life, it is imperative that they have adequate amounts of energy and natural resources. Unfortunately, China is thought to be relatively void of natural resources, beyond their rare earth and coal industries. India as well relies on outside sources to meet its resource needs. Since world resources are finite, countries like the US, China, India, Brazil and many others are likely to see an increase in competition and prices in the future.

There is no doubt that the US remains the sole superpower in the world, yet, at the same time it remains heavily reliant on outside resources like foreign oil. Without this oil, rare earths (used in manufacturing of technology equipment) and other items, the US economy would struggle. China is another economy that is rapidly consuming energy, and actually can't meet internal demand. In part this is due to western economies having strong relationships with most oil producing countries. If China and India can prove that they are reliable customers, major oil exporters could begin to favor Asian markets.

Asian influence on energy and resource markets

Trade agreements have already been signed, and many more are being created between emerging economies like China and those in South America. Brazil, which does most of its business with the US is looking for more options.

Ironically, it is the same country that Brazil wishes to link to, that has damaged its own manufacturing base. The world is changing, and Asian markets are capable of mass production at lower costs than virtually any other can compete with. At the same time, Asian economies are looking to expand their influence on energy and resource markets. In South America, they are buying massive amounts of land and signing exclusive rights to oil. This directly interferes with the sphere of influence already created by the US and other western markets.

In terms of political relations, India is on far better terms with the West than China. India has a major service economy which is heavily reliant on telecommunication contracts with other countries.

Again, this has created another opportunity for outsourcing to a country that can offer extremely cheaper services. Unfortunately, massive populations seem to have positive and negative effects. While this gives them a massive amount of cheap labor, it creates the opportunity for unrest and many less than ideal human rights issues.

Global demand for energy and resources, and Geopolitical relations

Geopolitical relations are extremely uneasy at the moment, especially in terms of energy and resources. As more people increase their standard of living, the demand for resources will continue increasing as well. The Asian energy business is likely to benefit the most from these demands, as long as it can continue expanding influence and secure much needed resources for the future. Countries in the west are looking for alternative energy options, partly because they know Asia is going to loosen their hold on foreign resource markets.
With the growth of the Asian energy business booming, it may benefit China to outsource some specific service resources from the US.  Companies turn to outsourcing their plant maintenance needs when their in-house maintenance program is failing, untrained, or time constrained.

With the proper training, instead of having to find the experts in the service required, your own team can become the experts. Many companies tend to feel more comfortable having the employees they know and trust to perform maintenance needs, especially when it comes to complicated, specialty tasks.
Also, should an emergency arrive, some companies prefer having a trained staff on hand to handle the situation should a service provider not arrive quickly enough. The in-house maintenance staff would also be more familiar and sensitive to your company’s priorities and preferences.

ACQUIP, INC laser alignment services and laser alignment training programs

A successful maintenance program finds their perfect balance between outsourcing and having a trained maintenance staff. Through the partnership with a service company, training, equipment, and the service itself can be provided as needed easing the maintenance process.

At ACQUIP, INC, we offer laser alignment services and comprehensive laser alignment training programs that are customized to your company’s needs.

To make the turbine work more efficiently is accomplished through a number of respective stages. These fundamental stages are synchronized on the basis of the source of energy, and together it is known as impulse or reaction turbines. Steam turbines usually use a blend of both the impulse designs and combination of reactions. But on the whole the turbines use the both, but in rare cases, some use either one of them. Respectively, high pressure turbines with impulse type and lower with the reaction type.

IMPULSE TURBINE

An impulse turbine another version of turbine with nozzles fixed to it, which maintains the flow of steam to the higher speed jets. These jets are molded in such a way with a desirable kinetic energy in which the rotor blades which are shaped as buckets, which help to change the direction of steam. Whenever the steam velocity increases the ratio of pressure decreases at the fixed blades.

When the steam flows through the nozzle, the pressure seems to be minimizing from internal pressure to external pressure. Steam is derived out through the nozzle with a high pressure with a huge velocity. During this time, blades on a whole acquire a maximum velocity of the steam. A large amount of energy gets lose during this period, and this energy is known by the name, ‘carry over velocity’ or ‘leaving loss’.

REACTION TURBINES

In the case of reaction turbines, the rotor blades are designed in such a way as to form convergent nozzles. This type of turbines helps to produce reaction force when the steam is produced through the nozzle formed by the rotor. Here steam is powered to the direction of rotor by the fixed vanes of the stator. The steam produced during this time makes stator in the form of a jet that the entire surface. The direction of steam varies according to the increasing speed of the blade. Once in a while the pressure seems to decrease among the stator and rotor. Even the pressure is decreased during the process, it does not affect the steam velocity, but there is a decrease both in pressure and temperature. The variation in speed and velocity does not affect the one who drives the turbine.

OPERATION AND MAINTENANCE

Whenever the turbine is undergone for a warm up for its use, the main steam superheated is allowed to pass through a bypass passage which helps to heat up the lines of the system along with the steam turbine. In order to prevent the uneven expansion of heat by the slow rotation of turbine during the time when there is no steam in the turbine. For this a turning gear is fixed. When the turbine initially is rotated by the turning gear, it helps to maintain a straight plane within a fixed time limit. After that, the turning gear is detached and the steam is forwarded to the turbine, initially to the ahead blades which makes the turbine to rotate from 10 to 15 RPM in order to warm up the turbine slowly.

A MODERN STEAM TURBINE GENERATOR INSTALLATION

Turbines are widely used because of its rare occurring problems and there is a minimum chance to have maintenance also. Rarely when there is an imbalance occurs in the case of rotor it can lead to the vibration of rotor which in rare cases lead the blade punching straight .It is necessary to notice that there is a minimum amount of water in the turbine and with a dry steam produced during the work of turbine. If the water content is high in the turbine there is a rare chance to produce erosion among the blades. This can even lead turbine to its terrible failure .Moreover when the water enters the turbine it results in the formation of thrust in the turbine shaft. In order to prevent the destruction of turbines, make sure the usage of high quality steam, then preventing the entrance of extra moisture inside the turbine passages are there installed within the passage of piping leading to the turbine.

A machine experiences thermal growth, or dynamic movement, more commonly understood as a change in temperature, from the time it starts until it is up to full power operation. This temperature change is a normal occurrence most notably in the supports and bearings of the machine.

To explain, thermal growth or dynamic movement means when a metal is heated to certain temperatures, it will without a doubt lengthen. The change can be minor, or it may be of more significance.

It is extremely important that machines be aligned properly. As machines transition from a cold start to a fully operating, high temperature level, it is critical that the thermal growth be monitored. This enables correctly adjusting a machine for unpredictable relative torque movement.

The optimum efficiency and alignment of your machines throughout their thermal range are crucial to the continuation of your business. ACQUIP, INC will monitor your machines thermal growth cycle, assuring your maximum productivity continues by configuring your machines with our superior laser- based alignment systems. Trust the reliability of your machines to ACQUIP, INC.
