The process of recycling electric motors should be direct and straightforward First, the recyclers collect many electric motors as possible to increase the possibility of getting enough copper. A hammer or hammering mill breaks the metallic casing of the motor. Then they separate the components and group them according to their materials.
Mar 16, 2020 Follow these practices to maximize electric-motor performance and longevity. By Mark Barnes, PhD, CMRP, Des-Case Corp. Treated correctly, electric motors can last a long, long time. In many cases, motors fail prematurely not because of any design, manufacturing, or installation issues, but from the most fundamental of root causes poor lubrication.

Jul 04, 2020 7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50 of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, printing presses, line shafts, elevators and compressors etc.
process pumps have been used extensively by oil refineries and the chemical and petrochemical industries. Featuring lower NPSH and higher performance values, these pumps are being widely used. Our modern tape controlled machines in conjunction with advanced quality control procedures insure that these pumps meet our high manufacturing standards.
The primary pump is usually driven by electric motor and the stand-by by diesel engine. It is possible to have two electric motor driven pumps if the electricity supply to each motor is taken from two totally independent supplies. The cable from each supply must also take different routes to
Electric motors represent over 80 of electricity use at a refinery since they are used to drive almost all of the minor processes. Of the motors used, 60 are used to drive pumps, 15 air compressors, 9 fans, and 16 other applications Reference 1. In the United States industrial applications and process industries including upstream oil ...
In a typical petrochemical complex, compressors for oil, gas and refrig-eration are the major consumers of energy. Historically, many compres-sors have been driven by gas turbines and engines. However, in recent years, electric motor ratings in the multimega-watt range have become common and economically competitive with turbines.
API610, the most widely used pump standard in the petrochemical and refining industries, includes experience-based recommendations for lubricant application, and one of these relates to oil mist. The API standard asks for oil mist to be routed through the bearings Figure 1. Figure 1 Oil mist applied to electric motor bearings Source ...
