Embodiment 1

[0037] like Figure 1-Figure 3 As shown, the exhaust ports 71 of the cylinder 5 are all opened on the side of the cylinder 5 at present. During the operation of the compressor, the exhaust port 71 is immersed in the refrigerating oil, and the refrigerant of the compressor is directly discharged into the refrigerating oil on the side, which will cause large exhaust resistance and serious overcompression, which will affect the performance and compression efficiency of the compressor; at the same time, it will As a result, the oil discharge rate of the compressor increases, which affects the energy efficiency of the air conditioning system.

[0038] A compressor pump body, such as Figure 4 and Figure 5 As shown, it includes a rotating shaft 1, a piston 2, a flange 3, a limiting plate 4 and a cylinder 5; the cylinder 5 is provided with a piston 2 and a rotating shaft 1, and the cylinder 5 and the rotating shaft 1 rotate around their respective centers. The suction channel 6 a...

Embodiment 2

[0045] On the basis of Example 1, such as Figure 5 , Figure 9-Figure 10As shown, the flange 3 includes two flanges 3 , the cross-sectional area of ​​the upper flange 3 is larger than that of the lower flange 3 , and the upper flange 3 is provided with an exhaust hole 74 . The limiting plate 4 includes two limiting plates 4 , the cross-sectional area of ​​the upper limiting plate 4 is larger than that of the lower limiting plate 4 , and the upper limiting plate 4 is provided with an exhaust hole 74 . The second exhaust passage 8 includes the exhaust hole 74 on the exhaust groove 73, the exhaust hole 74 of the upper flange 3 and the exhaust hole 74 of the upper limit plate 4, two exhaust holes 74 It is collinear with the center line of the exhaust hole 74 on the exhaust groove 73 . The cross-sectional area of ​​the upper limiting plate 4 is smaller than the cross-sectional area of ​​the upper flange 3 .

[0046] During assembly, the structure of the flange 3 and the limitin...

Embodiment 3

[0048] On the basis of Embodiment 1 and Embodiment 2, the corners of the cover plate 9 are provided with screw holes, and the positions of the screw holes are consistent with the positions of the preset mounting holes on the cylinder 5. 5 connected together. A sealing structure is provided between the cover plate 9 and the cylinder 5 .

[0049] The structure of the cover plate 9 is simple, easy to manufacture, and low in use cost; the cover plate 9 separates the exhaust groove 73 from the refrigerated oil; it is used in conjunction with a gasket, and the isolation effect is good; the upper end of the exhaust groove 73 is provided with an exhaust hole 74 to limit Vent holes 74 are provided at the corresponding positions of the plate 4 and the upper flange 3 to form the second exhaust passage 8, and the traditional side exhaust method is improved to the upper exhaust method.

[0050] The compressor discharges the refrigerant through the exhaust port 71. The refrigerant first en...

Abstract

The invention provides a compressor pump body. The pump body comprises a rotating shaft, a piston, a flange, a limiting plate, a cylinder and another cylinder, wherein an cylinder, a piston and a rotating shaft are arranged in the cylinder, an air suction channel is arranged on the cylinder, the limiting plate and the flange are respectively mounted on upper and lower sides of the cylinder, a first exhaust passage is arranged on a side edge of the cylinder, a cover plate for sealing the first exhaust passage is arranged on the side edge of the cylinder, the limiting plate and the flange at anupper portion of the cylinder are provided with second exhaust passages, the first exhaust channel is communicated with the second exhaust channels. The pump body solves a problem of side exhaust of the compressor pump body and prevents compressed refrigerant from being directly discharged into refrigerant oil. The compressor comprises the compressor pump body, and the compressor pump body is thecompressor pump body. Problems that side exhaust resistance is large, and compression efficiency is affected are solved, the oil spitting rate of the compressor is effectively prevented from being increased, and energy efficiency of an air-conditioning system is prevented from being affected.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to an upper exhaust compressor pump body and a compressor. Background technique [0002] The cylinder and the rotating shaft of the rotary cylinder piston compressor rotate around their respective centers, and the piston reciprocates simultaneously relative to the cylinder and the rotating shaft. The reciprocating motion of the piston relative to the cylinder realizes the periodic enlargement and reduction of the volume cavity; the relative circular motion of the cylinder realizes the communication between the volume cavity and the suction channel and the exhaust channel respectively; the above two compound movements realize the compression of the compressor. Inhalation, compression, exhaust process. [0003] The early scheme only opened one exhaust port, and in the later stage of exhaust, the distance between the piston head and the cylinder gradually decreases. At this time,...
