Shaft power selection and classification requirements of electric feed pump motor

- Dec 06, 2018-


Electric feed pump electric function is widely used in different fields, in addition to flammable, explosive or corrosive gas occasions, such as transport, mixing, printing, agricultural machinery and video processor applications, but also can be used with machine tools, pumps, blowers, compressors and other supporting equipment.

According to the classification of structure, the electric feed pump motor should be divided into vertical motor and horizontal motor. Because the working characteristics of the pump are relatively small starting torque, relatively small starting frequency, relatively long continuous running time and other characteristics, most of the pump motor is squirrel cage rotor asynchronous motor or synchronous motor.

Electric feed pump motor selection should be based on the shaft power, the motor power is greater than the shaft power of a class, to a certain extent, according to the requirements of actual working conditions, 2-pole motor is generally used in the case of small head height, flow rate (calculation is more complex).4 - pole motor is available for large flow and small head.Choose 4-pole or 6-pole motor for large flow rate and low head. When choosing 6-pole motor, the power can be reduced by one grade according to the shaft power.
