Screw pump is a rotary pump on the pump body and the screw formed by the meshing space volume change and move the transmission so that pressurized liquid or screw pump. According to the number of screw is divided into single screw pump, double screw pump and three screw pump screw pump speed. How to adjust? Ke Yu machinery Xiaobian introduce.

Screw pump flow and speed linearly relative to the low speed of the screw pump, screw pump high speed can increase the flow and head, but significantly increased power, high speed accelerated between the rotor and the stator wear, premature failure will make screw pump, and high speed screw pump rotor length is very short, easy to wear, and thus shorten the life of the screw pump.

Through the reducer or stepless speed regulation mechanism to reduce the speed, so that the speed of exploration is maintained at a reasonable range of three hundred rpm, compared with the high-speed running screw pump, the service life can be extended several times
