Self-priming centrifugal pump use and installation

1. The self-priming centrifugal pump is not suitable for conveying dirty oil, so the oil filter should be set at the inlet pipe end.

2. There is no safety valve in the pump. It is recommended to install a safety valve in the oil discharge pipeline to ensure the safe operation of the system.

3, self-priming centrifugal pump steering regulations: From the pump to the motor, the direction of rotation is counterclockwise.

4, the unit should be installed on the level of cement foundation, fixed with anchor bolts.

5, self-priming centrifugal pump installation height, does not exceed the allowable suction height.

6. The right shaft coupling should be coaxial. After the installation is completed, the shaft coupling can be smoothly operated without negative pressure. The self-priming centrifugal pump is a volumetric pump. The main and driven gears and the pump body, and the left and right pump covers constitute two closed spaces for oil inlet and outlet. When the gear rotates, the volume of the inlet cavity is continuously released due to the meshing teeth. From small to large. Vacuum is formed and the liquid is sucked in. There is a valley of teeth to the oil chamber, and the volume of the oil chamber is greatly reduced due to the continuous engagement of the meshing teeth, and the oil is discharged by being compressed so as to achieve the purpose of conveying the oil. This series of pumps is mainly composed of: left and right pump covers, pump bodies, main and passive gear shafts, bushings, oil seals and other components.
