High temperature pump structure and working principle

High temperature pump structure and working principle
A complete high temperature pump including motor, reducer, coupling and pump head several parts, the pump head part of the pump housing, front and rear side cover, gear shaft, sliding bearings and shaft seal composition. High-temperature pump is a positive displacement pump, work rely on the main and driven gears caused by the intermeshing changes in the volume of work to transport the melt. Working volume by the pump body, gear tooth groove and the function of the side plate with the composition.
When the gear rotates, the melt enters the tooth grooves of the two gears of the suction chamber. As the gear rotates, the melt is brought into the discharge cavity from both sides, and the gears mesh again to make the melt in the tooth grooves to be squeezed out Cavity, pressure delivery to the outlet pipe. As soon as the pump shaft is turned, the gear presses the melt down to the outlet side so that the pump outlet can reach very high pressure with little or no effect on flow and discharge pressure.
