Liquid Ring Vacuum Pump Operating Principle

The pumped medium is transported in the spaces between the blades and the liquid ring.

Liquid ring vacuum pump operating principle.

It operates on the principle of a rotary liquid piston. Dekker also offers a ti. 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. 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.

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. Find out how the nash liquid ring vacuum pump w. Liquid ring vacuum pumps can be used for wide applications on a very large scale. The impeller blades dip into the fluid and the centrifugal force exerted by their rotation forms a so called liquid ring within the housing.

Operating principle of liquid ring vacuum pumps. By the rotational movement of the impeller and the resulting centrifugal force the liquid within the cylinder forms the so called liquid ring. In these machines a liquid is made to act as a piston. How do liquid ring vacuum pumps and compressors work.

2 27 shows a cross section across the length of the liquid ring vacuum pump. They operate according to the positive displacement principle. Liquid ring vacuum pumps normally operate with water as the operating medium. This benefits the user with less wear and simpler affordable maintenance.

For more than 110 years nash liquid ring technology has provided reliable solutions for process applications. A liquid ring pump is a rotating positive displacement pump. 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 as the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller.
