What is the disadvantage of screw pump?
The pressure is about 3.4-340 kg / cm 2, the flow rate of up to 18600cm3 / min;
The screw pump has the following advantages:
The disadvantage of the screw pump is that the processing and assembly requirements of the screw are higher; the performance of the pump is more sensitive to the viscosity change of the liquid
3, because the pump part of the inertia of the rotating parts is low, it can use a very high speed;
5, the flow of uniform continuous, small vibration, low noise;
