Gear Pump Working Principle:

1.Gear pump is also called positive displacement device, that is like a cylinder in the cylinder piston, when a tooth into another tooth fluid space, liquid was mechanical way discharged. Because the liquid is incompressible, so the liquid and tooth can't occupy the same space at the same time, such, liquid was ruled out.

2.Due to the tooth continuous mesh, this phenomenon is continuous in to occur, thus in pump export provides a continuous exclude quantity, pump every one revolution, the amount of discharge is the same. With the drive shaft uninterruptedly rotation, the pump will unremittingly discharge fluid. Pump flow directly with the pump speed about.

3. In fact, in pump has a small amount of fluid loss, the pump efficiency can reach 100%, because these fluid is used to lubrication bearing and gear two side, and pump body is impossible without clearance fit, therefore, cannot make fluid from the 100% export discharge, so a small amount of fluid loss is inevitable. However pump can still operating well, for most extrusion material, it can still reach 93% ~ 98% efficiency.
