1、 G series stepless speed regulation screw pump product overview:
Stepless speed regulation is to increase the function of stepless speed regulation on the basis of the original G-type screw pump. Stepless speed control screw pump is also the use of motor to adjust the speed, and electromagnetic speed control screw pump the only difference is that the former is manual, but the latter is by magnetic field. The above two kinds of screw pump equipped with such special motor is to adjust the flow and pressure of the water pump to achieve the required standards.
The relationship between flow and speed is linear. Compared with the screw pump with low speed, the high speed screw pump can increase the flow and head, but the power is obviously increased. The high speed accelerates the wear between the rotor and stator, which must make the screw pump fail prematurely. Moreover, the length of the stator and rotor of the high-speed screw pump is very short, which is easy to wear, so the service life of the screw pump is shortened. Through the reducer or stepless speed regulation mechanism to reduce the speed, so as to keep the exploration speed within a reasonable range of 300 rpm. Compared with the high-speed running screw pump, the service life can be prolonged several times.
