With the rapid development of urban planning and construction, liquid ring vacuum pumps have found widespread application across many sectors. Offering advantages such as a long service life and low investment costs, these pumps demand high performance standards, which in turn places greater technical demands on their operation. Let us now take a look at the key considerations for installing liquid ring vacuum pumps.

1. Liquid ring vacuum pumps should be installed on a solid and stable surface, with sufficient space left around them to facilitate inspection, maintenance and servicing.

2. The foundation beneath the base must be level. It is recommended to place shock-absorbing rubber pads at the four corners of the base or to cast it in place using bolts to ensure smooth operation and minimal vibration.

3. The connecting pipes to the system must be securely sealed. For small units, metal piping with oil-resistant rubber gaskets may be used, or vacuum hoses may be employed; however, the pipe diameter must not be smaller than the pump’s inlet diameter, and the piping should be kept short with as few bends as possible.

4. In the piping system, the user may install a valve and a vacuum gauge above the inlet to monitor the pressure at any time.

5. Connect the power supply in accordance with the motor nameplate specifications, ensure the equipment is earthed, and install fuses and thermal relays of the appropriate rating.

6. During the power-on test run, the motor belt must be removed to confirm that the rotation direction complies with the specified direction before commissioning, to prevent oil spray caused by reverse rotation.

7. For screw vacuum pumps with cooling water, connect the cooling water supply in accordance with the specifications.

8. When installing a solenoid valve, the valve and this product must operate simultaneously.

9. If the discharged gas affects the working environment, a pipe may be fitted to the exhaust port to divert the gas away, or an oil mist filter may be installed.

The above outlines the precautions to be observed during the installation of water-ring vacuum pumps.
