Question:

To avoid broken material

To avoid broken material

Answer:

5, to maintain a constant export pressure
In this case, some screw pump is still installed on the pump body broken material shutdown device, when the breakage occurs, because the screw pump has its own characteristics of self-absorption, the cavity will produce a vacuum, vacuum device will stop the screw pump.
Screw pump is not allowed to operate in the case of broken material, once occurred, the rubber stator due to dry friction, and instantly produce high temperature and burned, so the grinder intact, grille is the normal operation of the screw pump one of the necessary conditions for
Screw pump is a positive displacement pump, when the outlet end blocked, the pressure will gradually increase, so that more than a predetermined pressure value.
