Theory Research on Full Metal Single Screw Pump

This paper first studied the feasibility in application and advantages of the the full metal single screw pump by the method of theoretical research . Then the paper deducted the motion characteristics of the rotor around the stator and flow rate of the metal single screw pump .It is pointed that the center of the rotor profile is always located in the long shaft of the section of stator in any section .As the rotor rotates, the center of the rotor profile on this section takes straight reciprocating motion along the long axis of stator section .The results indicate that it exists feasibility in the designing and processing of full metal single screw pump. Thereby it provides theoretical basis for the application of full metal screw pump.
