Abstract
The utility model discloses a direct current brushless silent water pump which comprises a water pump body. The water pump body comprises a rotor, a stator and a pump head fixed to the upper portion, wherein the rotor and the stator are in mutual joint. A pump cavity is formed between the rotor and the stator, a center shaft is arranged in the center of the rotor, a water inlet is formed in the center position, closes to the upper potion of the center shaft, of the pump head, a water inlet channel is formed between the center shaft and the rotor, and multiple sets of balancing holes are formed in the water inlet channel. The design of the balancing holes is adopted, the pump cavity can be filled with water at the moment of working, and negative pressure is generated in the water inlet at the same time to enable the rotor to lose balance so as to achieve mutual balance. Thus, the rotor is made to work in a free state, the friction resistance of the rotor with mechanical parts in the working process is reduced, and no mechanical friction noise exists in the working process of the water pump. Due to the fact that the pump cavity is filled with water fast, air in the water inlet channel can be exhausted within a short time, air noise generated by rotation of air in the pump cavity is reduced, noise pollution can be reduced by more than 80 percent, and the direct current brushless silent water pump has wide marketization prospects.
Description
Technical field
