A liquid band vacuum pump is easy to operate and is utilized in a number of applications across various industries. A liquid band pump works with a sealant needed in its procedure. This liquid could be water, oil or any various other solvent which is certainly rotated by an impeller within the casing of the pump.
As the shaft turns, a liquid ring is Liquid-Ring Vacuum Pump china created by the centrifugal force generated by the rotating impeller. This push holds the liquid band against the inner wall of the pumping chamber. Since the impeller is located eccentric to the pumping chamber, the depth of access of the blades into the liquid ring reduces and increases 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 escalates the pressure until discharge occurs 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 1st stage does not discharge to atmosphere. Rather, the initial stage discharges through the manifold resulting in the second stage along with through a discharge port positioned in the intermediate plate between the first- and second-stage impellers.
