A liquid ring vacuum pump is a rotating positive-displacement pump.
They’re ordinarily made use of a vacuum pump but can also be used as a fuel compressor. The function of a liquid ring pump is equivalent to a rotary vane pump, with the distinction becoming that the vanes are an integral part of the rotor and churn a rotating ring of liquid to kind the compression-chamber seal. They may be an inherently low-friction design, with the rotor remaining the sole moving aspect. Sliding friction is restricted towards the shaft seals. An induction motor typically powers liquid ring pumps.
The liquid ring vacuum pump compresses gas by rotating a cylindrical casing, which is eccentric. Liquid (typically water) is fed into the pump and, by centrifugal acceleration, kinds a moving cylindrical ring against the inside of the case. This liquid ring creates a series of seals inside the space concerning the impeller vanes, a type of compression chamber. The eccentricity concerning the impeller’s axis of rotation and the casing geometric axis results in a cyclic variation in the volume enclosed through the vanes plus the ring.
*Features
With compact structure and easy to repair.
It has a wide range of applications. It can pump all kinds of gases containing water vapor, flammable, explosive, a small amount
of dust and a small amount of liquid.
The main working medium is water, and the maintenance cost is low.
Able to work in harsh environment.
*Applications
SK series water/liquid ring vacuum pump and compressor are widely used in machinery, petrochemical, pharmaceutical, food, sugar, and electronic fields. In the working process, the gas compression process is constant temperature, so the compression and suction of explosive gas are not prone to explosion risk, so the use of a broader range.
