Gear pump structure and working principle: A complete gear pump includes a motor, a reducer, a coupling and a pump head. The pump head is composed of a pump casing, front and rear side covers, gear shafts, sliding bearings and shaft seals. The high-temperature gear pump is a positive displacement pump, which relies on the change in working volume caused by the meshing of the main and driven gears to transport the melt during operation. The working volume is composed of the pump body, the tooth groove of the gear and the bearing with the function of the side plate.
As long as the pump shaft rotates, the gear will push the melt to the outlet side, so the pump outlet can reach a very high pressure, and the flow rate is basically independent of the discharge pressure. Gear pump manufacturers and suppliers from China
