A liquid ring vacuum pump is easy to operate and is utilized in a number of applications across various industries. A liquid ring pump works together with a sealant necessary in its procedure. This liquid can be water, oil or any additional solvent which is definitely rotated by an impeller within the casing of the pump.
As the shaft turns, a liquid ring is created by the centrifugal force produced by the rotating impeller. This push holds the liquid band against the inner wall structure of the pumping chamber. Because the impeller is situated eccentric to the pumping Liquid-Ring Vacuum Pump china chamber, the depth of access of the blades into the liquid ring decreases and raises as the impeller rotates. This creates increasing cellular quantity on the inlet port side, creating vacuum.
On the discharge slot side, the impeller cell volume decreases as the blades move further into the liquid band. This increases the pressure until discharge occurs through the discharge interface.
A continuous flow of new sealing liquid is supplied to the pump via the sealing-liquid inlet.
Regarding the two-stage liquid band pump, the discharge from the 1st stage will not discharge to atmosphere. Rather, the 1st stage discharges through the manifold leading to the second stage and also through a discharge port situated in the intermediate plate between the first- and second-stage impellers.
