Embodiment

[0019] In this embodiment, the flow channel is figure 1 The transmission channel along the direction of the arrow in the middle position.

[0020] Such as figure 1 and figure 2 As shown, the DC brushless silent water pump provided in this embodiment includes a water pump main body, and the water pump main body includes a rotor 004 and a stator 005 connected to each other and a pump head 003 fixed on the upper part. The rotor 004 and the stator 005 A pump chamber 008 is formed between them, a central shaft 007 is set in the center of the rotor 004, and a water inlet 001 is provided at the center of the pump head 003 close to the upper part of the central shaft 007, and an inlet 001 is formed between the central shaft 007 and the rotor 004. A water channel, and multiple groups of balance holes 009 are set in the water inlet channel.

[0021] The water inlet 001 is filled with water and flows into the pump chamber 008, the balance hole 009 is filled with water when the pump c...

Abstract

The invention discloses a direct-current brushless mute water pump, which comprises a water pump main body, wherein a rotor, a stator and a pump head are arranged inside the water pump main body, the rotor and the stator are mutually connected with each other, the pump head is fixed on the upper part of the water pump main body, a pump cavity is formed between the rotor and the stator, the center of the rotor is provided with a central shaft, the central position, adjacent to the upper part of the central shaft, of the pump head is provided with a water inlet, a water inlet passage is formed between the central shaft and the rotor, a plurality of groups of balance pores are arranged in the water inlet passage, the pump cavity can be instantaneously fully filled with the water by adopting the design of the balance pores, and the negative pressure is generated in the water inlet, so that the rotor is imbalanced, the rotor and the stator are mutually balanced, the rotor is enabled to work under the freedom state, the friction resistance force between the rotor and a mechanical member in work can be reduced, and no mechanical abrasion noise is realized when the water pump works; since the pump cavity is rapidly filled with the water, the air inside the water passage can be thoroughly emptied in a short time, the air noise generated by the rotation of the air in the pump cavity can be lowered, more than 80 percent of noise pollution can be reduced, and the direct-current brushless mute water pump has broad market prospect.

Description

technical field [0001] The invention relates to the design technology of a silent water pump, in particular to a DC brushless silent water pump. Background technique [0002] During the working process of traditional water pumps, unpleasant noises will be generated due to the friction between mechanical parts and rotors or the friction between rotors and air, which will cause huge noise pollution to the working environment. [0003] In order to change the above-mentioned technical problems, especially to avoid adding redundant auxiliary parts and avoid increasing the manufacturing cost, it is necessary to improve the design of the components of the water pump itself, and to solve the above-mentioned technical problems through the innovation of structural design. Contents of the invention [0004] The purpose of the present invention is to provide a DC brushless silent water pump, which adopts a balance hole design to effectively solve the above technical problems. [0005...
