Internal Gear Pumps Works: 7 Things To Note 1. The drive shaft of the electric pump is connected to the motor shaft using an elastic coupling or a chain coupling. 2. The pump drive shaft cannot withstand any radial vertical force, and the lateral driving methods such as belts, chains, gears are prohibited. 3.The strength of the bottom plate should be enough, not for a long time, the bottom plate of the pump is soft, which will cause the motor and the pump to be misaligned and damage the pump. 4. When the gear pump tightens the end bolts, the gear pump force should be symmetrical and uniform; move the rotor while tightening. If a jam occurs, the gear pump should be loosened and re-tightened. 5.Find out the maximum allowable speed of the pump. 6. Make sure the fluid enters the inlet, and try not to dry and dry. 7.Do not reverse the inlet and outlet of the pump. It will cause the pump not to discharge.
