There are a lot of shops that provide industrial pump repair services. But how do you find a good one for your needs? What are the qualities of an excellent industrial pump repair shop? Provide a Wide Range of Repairs and Services for Industrial Pumps A solid industrial pump repair shop should be able to handle many different repairs and services such as: Replacing old pumps and installing new pumps Replacing parts Performing coupling, seal and base repairs Providing predictive maintenance services such as vibration testing to help identify problems before they become urg
Everyone has heard of, and understands what electric motor preventive maintenance is, but what exactly is electric motor predictive maintenance? Electric motor predictive maintenance is when you use non-destructive tests such as infrared thermographic studies and electric motor vibration analysis to electric motors currently in service to identify possible problems so that corrections can be made before they become serious problems requiring an unplanned work interruption. Essentially electric motor predictive maintenance tries to “predict” and correct problems before they become
One of the challenges of working with electric motors is determining what to do when the motor fails. Do you rewind the motor or replace it? Here are some things to consider when determining if using a motor rewinding service is right for your motor: How Old is the Motor? The age of the motor is a factor due to the standards established by the Energy Policy Act of 2005, and the Energy Independence and Security Act of 2007. These laws established new efficiency requirements for electric motors (as part of the overall program) and these motors are far more efficient and thus less expensive
Unbalance is one of the major causes of electrical motor failures requiring often expensive repairs or replacement. One of the best ways to prevent this from happening is to perform dynamic field balancing services at the first sign of trouble. What are the Causes of Unbalance in Electrical Motors? In general, they are all caused by an uneven distribution of mass around an axis of rotation. This uneven distribution can be traced back to several different causes such as a buildup of dirt or grease on fans, normal wear-and-tear of moving parts, or corrosion within the bearings, rotor, or s
An unbalanced electric motor can cause many problems. The most significant of which being a catastrophic failure due to excess vibration that result in bearing failure, cracks, and other structural defects. Here are just a few of the benefits of dynamic balancing. Minimizes Noise A well-balanced electric motor is a quiet electric motor. Noise is one of the first signs of a problem. Excess noise is the result of vibration and vibration, if left unattended, makes the problem worse. In addition, noise can annoy or cause fatigue in the operator or others at the workplace leading to lost pr
Hipot (or high potential testing) is a non-destructive test that has many names: overvoltage testing, dielectric breakdown test, dielectric withstand test, or insulation resistance tests. All of these tests are designed to make sure that the insulation used in your electric motors are doing their jobs. If the insulation is defective or not performing as expected, the results can lead to power leakage or short circuits which may cause the motor to fail or damage it. Another huge danger of defective insulation is the risk of shock to anyone who comes in contact with that motor. A Hipot tes
When your electric motor is not performing as expected, you often must make a critical decision about it: Rewind it or replace it. There are some instances where rewinding a motor simply is not a practical solution, but many times using a motor rewinding service is a better, lower cost, option. Here are the benefits of using a motor rewinding service: Saves money At less than half the cost of replacing an electrical motor, a motor rewind is an especially cost effective solution when considering large enclosed motors over 100hp. Saves time Most motor rewind jobs take less than x # of hou
A well run industrial electric motor asset management program allows a company to get the most out of its existing electrical motors, as well as making good decisions on whether to repair or replace existing electric motors. Reduce Energy Costs When your existing industrial electric motors are running at peak efficiency, you are saving money on energy costs. And since this is estimated to be 95% of an electrical motor’s operating cost over a lifetime, this savings can be huge. With this in mind, a decision may need to be made about replacing an older, less efficient electric motor, with a
An industrial electric motor asset management program helps assure that all of your critical electric motors are running at peak efficiency as well as remaining cost effective for your business. How do you set up an industrial asset management program? Read on. Start a Program Get buy in from management by showing the benefits of an electric motor asset management program, and appoint someone to be in charge of it. Inspect and Test Existing Electric Motors This is one of the most important actions you can take for your industrial electric motor asset management program. Get your motors
NEMA stands for the National Electrical Manufacturers Association. As part of the Energy Independence and Security Act of 2007 (EISA), this organization helped create the provisions for this law surrounding the improvement of motor efficiency in order to reduce the energy and operating costs for industrial, commercial and institutional buildings, reduce electric consumption for electrical motors and reducing pollution as a result, and help identify higher efficiency electric motors for customers. NEMA Premium Motors Reduce Carbon Emissions NEMA also established a NEMA Premium energy efficien
