Vacuum pump is a kind of device which can get vacuum by pumping air from the container, which is mainly used in various industries. So let's make up for you about how to install the vacuum pump correctly.

1. For the vacuum pump with cooling water, turn on the cooling water according to the rules.

2. 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 when the rotation direction of the vacuum pump meets the rules, so as to prevent the vacuum pump from rotating and injecting oil. (turn in the direction indicated by the shield)

3. When the gas discharged from the vacuum pump affects the working environment, the pipeline can be installed at the exhaust port to lead away or install the oil mist filter.

4. If the vacuum pump port is equipped with solenoid valve, the valve and vacuum pump should act together.

5. Connect the power supply according to the motor label rules, and connect the ground wire with the fuse and thermal relay of appropriate standard.

6. In the connecting pipeline, the user can install a valve and a vacuum gauge above the air inlet of the vacuum pump to check the limit pressure of the vacuum pump at any time.

7. The connecting pipeline between vacuum pump and system shall be sealed firmly. Metal pipeline connection can be used for small vacuum pump, oil resistant rubber can be used for sealing gasket, and vacuum rubber pipe can be used for small vacuum pump connection. The pipe diameter shall not be less than the suction diameter of vacuum pump, and the pipeline shall be short with few elbows. (when welding the pipeline, the welding slag in the pipe should be removed, and it is forbidden to enter the vacuum pump cavity. )

8. The vacuum pump should be installed on the ground in a solid and solid place, with plenty of places around for easy inspection, maintenance and maintenance.

9. The foundation level should be maintained under the base of vacuum pump. The damping rubber or bolt casting device should be used at the four corners of the base to ensure the stable operation and small oscillation of the vacuum pump.
