Liquid ring vacuum pump-compressor with double function of liquid ring with separate sources

摘要

An improved liquid ring vacuum pump apparatus and method for reducing wear between the cone and rotor vanes, by reducing the water flow contacting these parts, by injecting only fresh water into the seal segment while injecting secondary water into the pump through the housing. The apparatus includes dual water injectors, one injector at the periphery of the housing, and a second injector central within the housing, each of which is supplied by a different water source. A novel cone structure including grooves and notches for directing fluid to specific segments within the pump.
