As water-ring vacuum pumps have become widely used in our daily lives, their operational characteristics and advantages have gained widespread recognition. To ensure their optimal use, let us take a look at the upper and lower limit issues associated with water-ring vacuum pumps.

Water-ring vacuum pumps have delivered excellent results across many industries. Given their strong vacuum performance and overall effectiveness, it is essential to set an upper limit for the vacuum system during operation. For example, if the upper limit is set at –0.08 MPa and the lower limit at –0.06 MPa, upon starting the system, one of the Roots vacuum pumps will begin operating until the vacuum level in the vacuum tank exceeds the upper limit of –0.08 MPa, at which point the water-ring vacuum pump automatically stops operating and the vacuum tank’s vacuum check valve automatically shuts off.

If, due to operational requirements, the vacuum level in the vacuum line drops below –0.06 MPa, the other water-ring vacuum pump automatically starts up until the vacuum level in the vacuum line rises to the upper limit of –0.08 MPa. This cycle repeats continuously, ensuring that the vacuum level in the vacuum tank is always maintained between the upper and lower limits. When the upper and lower limits of a liquid-ring vacuum pump are set appropriately, the equipment’s operational efficiency is enhanced in many respects throughout its service life.

The above covers the issue of upper and lower limits for liquid-ring vacuum pumps. You may select the appropriate method based on actual operational requirements to avoid unnecessary losses caused by indiscriminate operation.
