In terms of terminology, a gear pump is also called a positive displacement device, that is, like a piston in a cylinder, when a tooth enters the fluid space of another tooth, the liquid is mechanically squeezed out. Because the liquid is incompressible, the liquid and the teeth cannot occupy the same space at the same time, so that the liquid is eliminated. Due to the constant meshing of the teeth, this phenomenon occurs continuously, thus providing a continuous discharge at the outlet of the pump. The amount of discharge is the same for each rotation of the pump. With the uninterrupted rotation of the drive shaft, the pump also discharges fluid without interruption.
Gear pump basic working principle
The concept of the gear pump is very simple, that is, its basic form is that two gears of the same size rotate in mesh with each other in a close-fitting housing. The inside of the housing resembles an “8†shape with two gears inside. The outer diameter of the gear and both sides are in close cooperation with the housing. The material from the extruder enters the middle of the two gears at the suction inlet, fills this space, moves along the housing as the teeth rotate, and finally exits when the two teeth mesh.
