Problems solved by technology
Commonly used vane pumps use the interaction between rotating vanes and water to transfer energy, including centrifugal pumps, axial flow pumps and mixed flow pumps; existing vane pumps need to drive the motor to run at high speed during use, otherwise it will cause The problem of low water pressure and small head, and the existing vane pump also has the phenomenon of backflow. The water pumped into the outlet pipe and the water delivery pipe has a reaction force on the blades, and part of the power of the drive motor is used to offset this part. Reactive force, less efficient use

The invention discloses an eccentric rotor water pump, which comprises a pump body, a connecting disc, a drive motor and a water outlet pipe, wherein the drive motor is connected with the pump body through the connecting disc; and the top end of the pump body is fixedly connected with the water outlet pipe. The eccentric rotor water pump has the advantages that: a stator and a rotor are arranged eccentrically; a water suction inlet and a water outlet are formed on the side wall of the stator; the gap between an eccentric rotor and the stator is reduced in the eccentric rotor rotation process, so that the pressure of water between two blades is gradually improved; water with certain pressure flows into the water outlet pipe from the water outlet and then flows out of the water outlet pipe, so that the phenomenon of backflow of the water is prevented; and the water pump can be driven only by a low-speed motor, so that efficiency is improved, and electric power resources are saved simultaneously.
Description
technical field [0001] The invention relates to a water pump, in particular to an eccentric rotor water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. The technical parameters to measure the performance of the pump include flow, suction lift, lift, shaft power, water power, efficiency, etc. Commonly used vane pumps use the interaction between rotating vanes and water to transfer energy, including centrifugal pumps, axial flow pumps and mixed flow pumps; existing vane pumps need to drive the motor to run at high speed during use, otherwise it will cause The problem of low water pre...
