Abstract

The invention relates to the technical field of displacement pumps and particularly relates to a three-rotor displacement pump. The three-rotor displacement pump comprises a pump shell, wherein a main rotor, a first secondary rotor and a second secondary rotor are arranged in the pump shell; the first secondary rotor and the second secondary rotor are arranged at two sides of the main rotor and can be in contact with the main rotor all the time; the first secondary rotor and the second secondary rotor are in contact with the inner wall of the pump shell all the time in the rotation process; a first liquid inlet, a first liquid outlet, a second liquid inlet and a second liquid outlet are formed in the outer wall of the pump shell in sequence; the first liquid inlet and the first liquid outlet are formed in one side of the main rotor; the second liquid inlet and the second liquid outlet are formed in the other side of the main rotor; the first liquid inlet and the first liquid outlet are formed in two sides of the first secondary rotor respectively; the second liquid inlet and the second liquid outlet are formed in two sides of the second secondary rotor respectively. Through the three-rotor displacement pump, the liquid is sucked and discharged for four times by the pump when the main rotor rotates a circle; both the output flow and the working efficiency of the pump are improved.

Description

technical field [0001] The invention relates to the technical field of displacement pumps, in particular to a three-rotor displacement pump. Background technique [0002] Positive displacement pumps refer to pumps that use the change in the volume of the pump cylinder to transport liquid, such as reciprocating pumps, rotor pumps, etc. [0003] Reciprocating pump: [0004] A reciprocating pump is a pump that uses the reciprocating motion of the piston to transport the liquid, and the energy is directly transmitted in the form of static pressure energy by the reciprocating motion of the piston. Since the liquid is incompressible, when the piston presses the liquid, the liquid can be subjected to a high pressure, thereby obtaining a high lift. [0005] Rotor pump: [0006] The rotor pump is composed of a stationary pump casing and a rotating rotor. The side of the rotor in the pump body in contact with the liquid directly acts on the liquid in the form of static pressure, an...
