Embodiment 1

[0031] Such as figure 1 As shown, the pump body assembly of Embodiment 1 includes an upper flange 10, and the upper flange 10 includes a disk portion 11 and a neck 12 extending upward from the disk portion 11. The outer peripheral surface of the disk portion 11 is connected to the casing of the compressor. The height a1 of the disc 11 and the distance b1 from the upper end surface of the neck 12 to the lower end surface of the disc 11 satisfy: 0.3≤a1 / b1≤0.4, b1 is the total height of the upper flange 10; The relationship between the height a1 and the diameter d1 of the disk portion 11 satisfies: 0.1≦a1 / d1≦0.2.

[0032] Applying the technical scheme of this embodiment, the ratio between the height of the disc portion 11 of the upper flange 10 and the diameter of the disc portion 11 and the ratio between the height of the disc portion 11 and the total height of the upper flange 10 are improved, so that Among the upper flanges with the same diameter, the upper flange of this emb...

Embodiment 2

[0046] The pump body assembly of the second embodiment changes the way of fixed connection with the housing, specifically, as Figure 6 As shown, the outer peripheral surface of the cylinder 20 of the pump body assembly of this embodiment is connected to the casing of the compressor. In order to achieve an effect similar to that of Embodiment 1, the height of the outer peripheral surface of the cylinder 20 of this embodiment is a2, and the neck The distance between the upper end surface of 12 and the lower end surface of cylinder 20 is b2, and the distance between a2 and b2 satisfies: 0.2≤a2 / b2≤0.3. The diameter of the cylinder in this embodiment is d2, and the relationship between a2 and d2 satisfies: 0.1≤a2 / d2≤0.2.

[0047] Preferably, the outer peripheral surface of the cylinder 20 in this embodiment is welded to the casing of the compressor.

[0048] The present invention also provides an air conditioner. The air conditioner (not shown in the figure) according to this emb...

Abstract

The invention provides a pump body assembly, a compressor and an air conditioner, wherein the pump body assembly includes an upper flange, the upper flange includes a plate portion and a neck extending upward from the plate portion, the outer peripheral surface of the plate portion and the compressor The shell connection, the height a1 of the disk and the distance b1 from the upper end surface of the neck to the lower end surface of the disk satisfy: 0.3≤a1 / b1≤0.4, between the height a1 of the disk and the diameter d1 of the disk Satisfy: 0.1≤a1 / d1≤0.2. The technical scheme of the invention effectively solves the problem in the prior art that the motor coaxiality difference of the compressor affects the reliability of the compressor and causes noise.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a pump body assembly, a compressor and an air conditioner. Background technique [0002] The rotary compressor is composed of a motor assembly and a pump body assembly sealed inside the casing. The motor assembly is composed of a stator fixed on the inner wall of the casing and a rotor connected to the pump body assembly. The maximum shaft center of the stator and rotor in the motor is The deviation is called concentricity. The coaxiality of the motor plays a vital role in the operation of the compressor. If the coaxiality of the motor is poor, that is, the axis deviation between the rotor and the stator is large, uneven electromagnetic force will be generated during the rotation of the rotor, which will affect the compression. The machine runs smoothly and generates electromagnetic noise. In severe cases, the outer wall of the rotor and the inner wall of the stator will be worn...
