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.
Water ring vacuum pump working principle.
Liquid ring vacuum pumps typically use a liquid seal to achieve a vacuum.
Water ring vacuum pump working principle.
Before the vacuum of the condenser is established the water ring vacuum pump directly vacuumizes the condenser through the isolation valve at the inlet of the vacuum pump group and the bypass valve of the front air extractor.
As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller.
Sliding friction is limited to the shaft seals.
The liquid is generally water for most of the applications and hence they are also known as water ring water piston or liquid piston rotary pumps and compressors.
Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical electrical power environmental food beverage processing and packaging marine mining oil gas pharmaceutical pulp paper and textiles.
Quite often a cooling water system is also in place so as to dissipate the heat produced during operation.
As shown in the diagram of the working principle of the liquid ring pump the liquid ring pump is composed of impeller pump body suction and exhaust disc liquid ring formed in the inner wall of the pump body suction port exhaust port auxiliary exhaust valve etc.
The most widely used liquid is water typically used once through and rejected to drain.
Liquid ring vacuum pumps and compressors are rotary machines.
They are an inherently low friction design with the rotor being the only moving part.
The impeller is eccentrically installed in the pump body.
In these machines a liquid is made to act as a piston.
They operate according to the positive displacement principle.
Through the centrifugal installation of impeller and pump chamber the purpose of suction compression and exhaust is achieved and the vacuum i e.
Liquid ring vacuum pumps utilize water or other processes compatible liquid as the sealant.
Its joint working principle is.
This force holds the liquid ring against the inner wall of the pumping chamber.
The rotation of the blades in the circular case generates working spaces.
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.
Working principle of water ring vacuum pump water ring vacuum pump is provided with a balanced rotor that is shaped as a cylinder with a hollow hub it is attached to radial blades that rotate freely in a circular casing.
1 impeller 1 eccentric mounted pump body 2 internally when the impeller rotates the water is acted by centrifugal force and forms a rotating water ring on the pump wall.
Water ring vacuum pump is cantilever structure as shown in fig.
