Reasons and elimination of screw pump not sucking oil

Reasons and elimination of screw pump not sucking oil
The reason why the screw pump does not absorb oil may be caused by blockage or leakage of the suction line, the suction height exceeds the allowable vacuum height, the motor reverses, the medium viscosity is too large, etc., then the solution corresponding to the three-screw pump should be to repair the suction pipe. Road, reduce suction height, change motor steering, warm media, etc.
1. The shaft seal is not adjusted well - from the new adjustment
2. The seal ring wears and the gap increases - properly tighten the bolt or replace the seal
3. Mechanical seal dynamic and static ring wear surface damage or trade-off - replace the seal or re-grind
4. Spring relaxation - replacement spring

The liquid pumped by the three-screw pump is a kind of lubricating liquid containing no solid particles, no corrosive oils and the like. The viscosity of the liquid to be transported is 1.2~100OE (3.0~760cst), and the liquid containing high viscosity can also be heated. After the viscosity reduction, transport.

Flow range: 0.2~590m3/h, maximum working pressure 100bar, maximum temperature 150°C
