ABSTRACT:
A liquid ring vacuum pump or compressor includes an off-centered housing and a rotor shaft assembly within the housing. The liquid ring vacuum pump or compressor also includes a port-containing one member having a frustoconical shape positioned in the rotor. The rotor rotates liquid around the cone member forming an off-centered cylindrical liquid ring that is shaped by and centered in the off-centered housing. The invented cone member has an inlet port having a parabolic shaped opening edge and a discharge port having a parabolic shaped closing edge. The invented cone member fully supports the liquid ring, at the intersection of the inner surface of the cylindrical liquid ring and the outer surface of the wall of the frustoconical cone member and inhibits the flow of water into the ports, maximizes the amount of gas being displaced through the cone member, increases the capacity of the liquid ring vacuum pump, and reduces the cost of operating the pump. A method of reducing water usage in a liquid ring vacuum pump is also disclosed.
