1. The vacuum pump should be installed in a solid place with sufficient space around for inspection, maintenance and maintenance.
2. The foundation level should be kept under the base of vacuum pump. It is suggested to pad damping rubber or install with bolts at four corners of the base to ensure smooth operation and small vibration of vacuum pump.
3. The connecting pipe between vacuum pump and system shall be sealed reliably. Metal pipeline connection can be used for small vacuum pump, oil resistant rubber shall 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. (the welding slag in the pipe should be removed when welding the pipeline, and it is forbidden to enter the vacuum pump cavity.)
4. 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.
5. Connect the power supply and ground wire according to the motor label, and install fuse and thermal relay with appropriate specifications.
6. When the vacuum pump is powered on for test run, 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 specified direction, so as to prevent the vacuum pump from reversing and injecting oil. (turn in the direction indicated by the shield)
7. For the vacuum pump with cooling water, connect the cooling water according to the regulations.
8. If a solenoid valve is installed at the vacuum pump port, the valve and the vacuum pump should act at the same time.
9. 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
