Magnetic levitation water pump

Abstract

The invention discloses a magnetic levitation water pump which comprises a shell, a rotor, a stator, an impeller, a first rotating shaft and a second rotating shaft, wherein a first chamber and a second chamber are arranged in the shell; the stator is arranged in the first cavity; the impeller is arranged on the rotor so as to synchronously rotate around the rotating axis along with the rotor; the first rotating shaft and the second rotating shaft are sequentially arranged along the rotating axis, the opposite ends of the first rotating shaft and the second rotating shaft are connected to the shell, two ends of the rotor movably act on the opposite ends of the first rotating shaft and the second rotating shaft respectively, and the rotor is provided with a magnetic part arranged around the rotating axis, so that the rotor can be suspended between the opposite ends of the first rotating shaft and the second rotating shaft. Therefore, no friction exists between the rotor and other parts when the rotor rotates, so that the mute effect is good; heat generated by friction is also avoided, the suspended arrangement can better dissipate heat, the failure rate is reduced, the service life of the water pump is prolonged, the operation energy consumption and the operation cost are reduced, the water pump is good in operation stability, and the system efficiency is high.

Description

technical field [0001] The invention relates to the technology in the field of water pumps, in particular to a magnetic levitation water pump. Background technique [0002] At present, a water pump is a device used to transport working fluid. When liquid such as water enters the pump, the impeller inside the pump pressurizes the liquid, and then sends the liquid out of the pump to achieve the purpose of liquid delivery. [0003] Existing water pump rotors generally use one rotating shaft. During the long-term working process of the water pump, the rotor rotates and the rotating shaft rubs against other parts. On the one hand, it will cause product noise, and on the other hand, friction loss will occur, resulting in high energy consumption during operation. . In addition, when the current water pump is working, impurities are prone to clogging, which causes the water pump to rotate hard, consumes a lot of energy, and even causes loss and failure of the water pump, which affe...
