Liquid Ring Vacuum Pump Operating Principle

An eccentrically installed impeller rotates in the casing partly filled with liquid.

Liquid ring vacuum pump operating principle.

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. An eccentrically mounted impeller rotates in a housing partially filled with operating fluid. For more than 110 years nash liquid ring technology has provided reliable solutions for process applications. Liquid ring vacuum pumps normally operate with water as the operating medium.

The impeller blades dip into the fluid and the centrifugal force exerted by their rotation forms a so called liquid ring within the housing. The pumped medium is transported in the spaces between the blades and the liquid ring. How do liquid ring vacuum pumps and compressors work. Dekker also offers a ti.

Liquid ring vacuum pumps can be used for wide applications on a very large scale. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring. This benefits the user with less wear and simpler affordable maintenance. Find out how the nash liquid ring vacuum pump w.

2 27 shows a cross section across the length of the liquid ring vacuum pump. The shaft and impeller assembly are mounted eccentrically relative to the. A liquid ring pump is a rotating positive displacement pump. 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.

Operating principle of liquid ring vacuum pumps. 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. 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. In these machines a liquid is made to act as a piston.
