(1) the vacuum pump shall be assembled in a solid place on the ground, and sufficient space shall be reserved around it for routine inspection, maintenance and maintenance.

  (2) keep the foundation level under the vacuum pump base. It is recommended to pad damping rubber or cast and assemble with bolts at the four corners of the base to effectively ensure the smooth operation of the vacuum pump and small vibration.

  (3) the connecting pipeline between the vacuum pump and the system shall be sealed stably and reliably. For small vacuum pumps, metal pipeline connection gasket and oil resistant rubber can be selected. For small vacuum pumps, vacuum rubber hose can be selected for connection. The pipeline diameter shall not be less than the suction diameter of the vacuum pump, and the pipeline shall be short and less elbows. (when welding the pipeline, the welding slag in the pipeline shall be removed, and it is strictly prohibited for the welding slag to enter the vacuum pump chamber.)

  (4) in the connecting pipeline, the user can assemble the valve and vacuum gauge at the upper end of the air inlet of the vacuum pump, and check the limit pressure of the vacuum pump at any time.

  (5) connect the power supply according to the provisions of the motor identification plate, connect the grounding wire and assemble the fuse and thermal relay of appropriate specification.

  (6) when the vacuum pump is powered on for trial operation, the motor belt must be removed and the vacuum pump can be put into use only after confirming that the rotation direction of the vacuum pump meets the requirements, so as to prevent the reverse rotation of the vacuum pump for oil injection. (follow the direction indicated by the protective cover)

  (7) for the vacuum pump with cooling water, connect the cooling water according to the regulations.

  (8) if the solenoid valve is assembled at the vacuum pump port, the valve and the vacuum pump shall act at the same time.

  (9) when the gas discharged from the vacuum pump affects the working environment, a pipe can be installed at the exhaust port to lead away or install an oil mist filter.
