Simulation Study for the Effects of Clearance Volume on Full Metal Single Screw Pump Performance

Abstract:

The stators and rotors of full metal screw pump take way of clearance fit, so the clearance value will directly affect the pump lifting performance and efficiency. Firstly using the finite volume method to establish a full-metal single screw pump 3D model, secondly using FLUENT software to calculate outlet pressure changes with different series of clearance value between the stator and the rotor of the pump in condition of the same inlet pressure .lastly Drawing outlet pressure change curves to evaluate the concrete effect of clearance volume on the performance of the pump. The results indicate that the pump outlet pressure increased first and then decreased with increasing clearance value and that pump has good lifting oil capacity with clearance value which is less than 0.5mm.
