Embodiment 1

[0068] The embodiment of the first aspect of the present invention provides a bearing assembly for a compressor. Such as figure 1 As shown, the bearing assembly includes a bearing 100 and an air injection channel 200 . Wherein, the air injection channel 200 is arranged on the bearing 100, and the air injection channel 200 includes at least two air injection sub-channels, and the at least two air injection sub-channels can communicate with the exhaust chamber of the compressor.

[0069] The bearing assembly provided by the embodiment of the present invention can use the air injection channel 200 to deliver the medium-pressure gas to the exhaust chamber of the compressor by opening the air injection channel 200 on the bearing 100, thereby reducing the exhaust temperature of the compressor, and at the same time can Improve the heating capacity of heat pump equipment using the compressor under low temperature conditions. Since the bearing 100 is only a part of the compressor, by...

Embodiment 2

[0074] On the basis of Embodiment 1, this embodiment describes the plugging structure of the air injection channel 200. Further, at least two air injection sub-channels include the first air injection sub-channel 202 and the second air injection sub-channel 204, and the first air injection sub-channel 204 The jet end of the channel 202 can be blocked by the piston 600 of the compressor; the bearing assembly also includes a check valve 300 , which is arranged on the bearing 100 , and the check valve 300 can block the jet end of the second jet sub-channel 204 .

[0075] In this embodiment, the at least two air injection sub-channels specifically include the first air injection sub-channel 202 and the second air injection sub-channel 204 that are blocked in different ways, so as to form different air injection mechanisms. It is worth noting that, for the jet sub-channel, the jet sub-channel includes the intake end and the jet end, and the intake end of the jet sub-channel can be d...

Embodiment 3

[0092] On the basis of Embodiment 1 or Embodiment 2, Embodiment 3 provides a bearing assembly. The bearing 100 includes a first bearing segment 102 and a second bearing segment 104 distributed along the axial direction. The outer diameter of the first bearing segment 102 is Larger than the outer diameter of the second bearing segment 104 , the jet ends of at least two jet sub-channels extend to the end surface of the first bearing segment 102 away from the second bearing segment 104 .

[0093] In this embodiment, the bearing 100 specifically includes a first bearing section 102 and a second bearing section 104 with a large outer diameter and a smaller outer diameter. The first bearing section 102 with a larger outer diameter can take on the role of a flange, and is compatible with the compressor. The cylinders 500 are connected, and the end surface of the first bearing section 102 away from the second bearing section 104 is the end surface of the bearing 100 corresponding to th...

Abstract

The invention provides a bearing assembly, a compressor and heat pump equipment. The bearing assembly is used for the compressor and comprises a bearing and an air injection channel. The air injectionchannel is arranged on the bearing, and comprises at least two air injection sub-channels; and the at least two air injection sub-channels can communicate with an exhaust cavity of the compressor. The air injection channel is formed in the bearing, and can be used for conveying medium-pressure air into the exhaust cavity of the compressor, so that the exhaust temperature of the compressor is reduced, and meanwhile, the heating capacity of the heat pump equipment applying the compressor under the low-temperature working condition can be improved. Due to the fact that the bearing is only one part in the compressor, the air injection channel is arranged on the part, and the main structure can be improved and concentrated on the part, so that the influence on other parts of the compressor issmall, and the improvement cost of the compressor can be reduced.

Description

technical field [0001] The invention belongs to the technical field of heat pump compressors, and in particular relates to a bearing assembly, a compressor and a heat pump device. Background technique [0002] Compressor is the core component of air-conditioning equipment, which can compress low-pressure refrigerant to form high-pressure gas. In the process of compressing the refrigerant by the compressor, the medium-pressure and medium-temperature refrigerant whose external pressure is between the suction and discharge pressure is injected into the cylinder, which can reduce the discharge temperature of the compressor, increase the suction and discharge flow, and improve the performance of the compressor. heating capacity and performance. However, under high speed conditions, the amount of air injection is often small, and the effect of improving the low-temperature heating capacity of the compressor is insufficient. Contents of the invention [0003] The present invent...
