Embodiment 1

[0027] The structure of the compressor equipped with the oil-gas separation balance weight of the present invention is as follows: image 3 As shown, it includes a compressor housing 1, a pump body 2, an accumulator 3, a stator 4, a rotor 5, and the like. Such as Figure 4 , 5 As shown, the rotor 5 is composed of an iron core in the middle and end rings 51 at both ends. The end of the rotor 5 is provided with a balance weight 7, the balance weight 7 can be made of the same material (aluminum) as the end ring 51, and manufactured according to the existing manufacturing process, for example: the balance weight 7 and the end ring 51 are die-cast together; or The balance weight 7 and the end ring 51 are manufactured separately, and then assembled by stamping, welding or riveting.

[0028] Such as Figure 6 As shown, the balance weight 7 is semi-circular and includes two end faces: a windward end face and a leeward end face. The balance weight 7 is provided with a channel 71 p...

Embodiment 2

[0032] Such as Figure 7 As shown, in this embodiment, the channels 71 include two. The two passages 71 are arranged side by side up and down, respectively passing through the two end faces of the balance weight. Each channel 71 is respectively provided with more than one oil return branch 72 communicating with the outer wall surface of the balance weight 7 .

[0033] Other structures are with embodiment 1.

Abstract

The invention discloses an oil-gas separated-type balancing block which is internally provided with a channel, wherein the channel penetrates through two end surfaces of the balancing block and is communicated with the outer side wall of the balancing block. By adopting a compressor equipped with the balancing block provided by the invention can separate refrigerating machine oil from gas refrigerant in the operation process, thus the oil discharge amount of the compressor is reduced, not only can the amount of refrigerating machine oil in the shell of the compressor be ensured, the service life and dependance of the compressor are improved, but also the heat transfer effect and energy efficiency of an air conditioner can be improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to an oil-gas separation type balance weight for a compressor. Background technique [0002] Existing compressors are generally composed of a compressor housing 1, a pump body 2, a liquid accumulator 3, a stator 4 and a rotor 5, such as figure 1 . In order to balance the unbalanced load of the compressor mechanism, such as figure 2 As shown, generally, a semi-circular balance weight 6 is die-cast on the end ring 51 of the rotor 5, and the side with the balance weight 6 on the rotor forms a weight difference with the opposite side without the balance weight to balance the compressor. role. The balance weight 6 is a half ring, and the two ends of the half ring are planes approximately perpendicular to the top of the rotor. [0003] Such as figure 2 As shown, in the existing compressor, when the compressor is running, the low-temperature and low-pressure refrigerant is compressed into...
