1. screw pumpperformance advantages:

1) Good inhalation performance, goodself-priming ability;

2) The flow is continuous and uniform, thenoise is low, and the vibration is small;

3) High speed can be used because theinertial force of the rotating parts in the pump is low;

4) Wide pressure and flow range;

5) The structure is solid and easy toinstall and maintain;

6)Less sensitive to incoming gases and dirt than other rotary pumps.

2. Screw pump performanceshortcomings

1) The performance of the pump is sensitiveto changes in the viscosity of the liquid;

2) Screw pump processing and assembly requirements are high.
