A liquid ring vacuum pump is simple to operate and is used in several applications across various industries. A liquid ring pump works with a sealant necessary in its procedure. This liquid can be water, oil or any other solvent which can be rotated by an Liquid-Ring Vacuum Pump china impeller within the casing of the pump.
As the shaft turns, a liquid band is created by the centrifugal force generated by the rotating impeller. This drive holds the liquid ring against the inner wall of the pumping chamber. Because the impeller is located eccentric to the pumping chamber, the depth of access of the blades in to the liquid ring reduces and improves as the impeller rotates. This creates increasing cellular quantity on the inlet interface side, creating vacuum.
On the discharge interface side, the impeller cell volume decreases as the blades move further into the liquid band. This escalates the pressure until discharge takes place through the discharge interface.
A continuing flow of refreshing sealing liquid is supplied to the pump via the sealing-liquid inlet.
Regarding the two-stage liquid ring pump, the discharge from the first stage will not discharge to atmosphere. Rather, the first stage discharges through the manifold resulting in the second stage in addition to through a discharge port located in the intermediate plate between your first- and second-stage impellers.
