1. Working principle
The structure of the pump is mainly composed of pump body, active and passive screw, shaft seals, bearing frame device, synchronous gear, safety valve and other components (see structure schematic drawing). There is no thread in the middle of the active and passive screw , but there are rectangular surface threads in the opposite direction from the left and right sides. The pump body, active and passive screw have a certain gap to ensure the self suction performance of the pump, active and passive screw tooth each other in rotating.
