Liquid Ring Vacuum Pump Working Principle Animation

As the impeller of a liquid ring vacuum pump rotates water which is the typical seal liquid used in this type of vacuum pump though other liquids can be employed is thrown about to form a literal liquid ring.

Liquid ring vacuum pump working principle animation.

As the rotor spins the seal liquid inside the pump forms a rotating liquid ring on the inner surface of the body forming the liquid ring. They are typically used as a vacuum pump but can also be used as a gas compressor the function of a liquid ring pump is similar to a rotary vane pump with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal. This force holds the liquid ring against the. An eccentrically installed impeller rotates in the casing partly filled with liquid.

To produce vacuum in a two stage liquid ring vacuum pump a multi blade impeller on a shaft is positioned eccentrically in a cylindrical housing that is partially filled with sealing liquid. Understanding the liquid ring vacuum pump and how it works. The working principle of a liquid ring pump is based around a pump body and an eccentric rotor. Environmental pumps do not require an oil change filter oil pans.

As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. Similar to other pumps a liquid ring vacuum pump lrvp has a bladed impeller attached to a center hub. Liquid ring vacuum pump. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring.

The fluid at the pump suction port flange has a low pressure value whereas after passing through the various pumps impellers stages the fluid is. Easy maintenance longer pump life liquid ring vacuum pumps are robust in construction and have only one moving part the rotor which is mounted on a shaft supported by a set of bearings designed for a long service life of continuous operation. This benefits the user with less wear and simpler affordable maintenance. Above figure shows construction exploded view of a typical flat plate type vacuum pump.

Liquid ring vacuum pumps normally operate with water as the operating medium. Industries that use this pump include glass canning plastics and food packaging.
