摘要： A liquid ring screw pump includes a housing with a suction inlet section and a pressure outlet section. Within the housing an Archimedes screw rotor is driven by a motor via a shaft. The inlet section and outlet section are each provided with connecting structure for suction and pressure piping respectively. The displacement CD of the screw rotor in relation to the center axis of the housing is determined by an equation based on the screw rotor radius, a minimum screw rotor core radius, and a variable k that is between 0.14 and 0.29.
