Screw must not be allowed to break at the expected operating circumstances, once happened, rubber stator do because of friction heat generated instantly burned, so, good grinder, screw grille flow are a necessary condition for the normal operation of one of For this reason, some screw pump was also installed devices break down material, when the expected happened when broken, because of the screw pump has self-priming function of its characteristics, the body will produce a vacuum chamber, vacuum devices will stop screw operation.
