Gear oil pump installed in reverse will cause leakage and wear
The installation of the double gear pump must be correct. Generally speaking, its inlet and outlet cannot be reversed, because it will cause leakage and wear, and the protection of the equipment will no longer exist. Although it can work if it is reversed, it can It's still unfavorable. Incorrect installation of the dual gear pump will cause the safety valve to fail, cause greater leakage, and cause greater wear on the bearings.Generally, the gear oil pump inlet and outlet are reverse installed, and the oil can also be oiled when the motor is reversed.However, the pressure in the shaft seal area is depressurized to the inlet side, which is equal to the inlet pressure. If the shaft seal is reversely installed, the shaft seal will withstand the outlet pressure, and the skeleton oil seal cannot withstand it.The double gear pump can be used in both forward and reverse directions, but if an integrated safety valve is configured, the safety valve must be adjusted, otherwise the safety valve will not work. Therefore, the installation of the double gear pump must be correct, and the relevant knowledge points must be understood before installation.
