Liquid Ring Vacuum Pump Operating Principle

The impeller blades dip into the fluid and the centrifugal force exerted by their rotation forms a so called liquid ring within the housing.

Liquid ring vacuum pump operating principle.

Environmental pumps do not require an oil change filter oil pans. It operates on the principle of a rotary liquid piston. Operating principle of liquid ring vacuum pumps. Dekker titan liquid ring vacuum pumps are offered in single stage with a vacuum range from 0 29 hgv available from 6 1 200 cfm.

Liquid ring vacuum pumps normally operate with water as the operating medium. A liquid ring pump is a rotating positive displacement pump. In these machines a liquid is made to act as a piston. Liquid ring vacuum pumps can be used for wide applications on a very large scale.

This benefits the user with less wear and simpler affordable maintenance. An eccentrically mounted impeller rotates in a housing partially filled with operating fluid. 2 27 shows a cross section across the length of the liquid ring vacuum pump. 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.

How do liquid ring vacuum pumps and compressors work. 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 as the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring. Find out how the nash liquid ring vacuum pump w.

The pumped medium is transported in the spaces between the blades and the liquid ring. An eccentrically installed impeller rotates in the casing partly filled with liquid. 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. For more than 110 years nash liquid ring technology has provided reliable solutions for process applications.
