Embodiment 1

[0053] Figure 2 to Figure 4 As shown, this embodiment provides a method for making an air supply port. In the step of determining the boundary equation group, each boundary equation group forms a set of setting areas, and the intersection of multiple sets of setting areas is used to determine the boundary range of the air supply port 1 . In this implementation, there are three sets of boundary equations, including boundary equations A, boundary equations B, and boundary equations C.

[0054] In this embodiment, when establishing the above-mentioned boundary equations, the coordinate origin of the boundary equations is set to be the cylinder center O of the rotary compressor, and the coordinate plane is the axial cross-section of the cylinder, represented by the XY plane.

[0055] Specifically, the boundary equations A, such as figure 2 shown, including: Curve Equation A1:X 2 +Y 2 =(r+e+m+a) 2 ;curve equation A2:X 2 +Y 2 =(r+e+m-a) 2 .

[0056] Among them, the curve ...

[0069] The body of the cylinder end cover and the gas supply port arranged on the body.

[0070] The air supply port is processed by the air supply port manufacturing method in the above-mentioned embodiment 1, so the cylinder end cover has all the advantages of the above air supply port structure, which will not be repeated here.

Embodiment 3

[0072] Figure 7 As shown, this embodiment provides a rotary compressor, including:

[0073] The cylinder end cover structure in Embodiment 2, so the rotary compressor has all the air supplement advantages of the above cylinder end cover structure.

[0074] Or include the air supply port obtained by processing the air supply port in the above-mentioned embodiment 1.

Abstract

The invention provides a manufacturing method of an air makeup port and an air cylinder end cover and a rotary compressor. In determining a boundary equation group, each boundary equation group formsa set of setting regions respectively, and a plurality of sets of setting regions intersect to determine a boundary range of the air makeup port. The opening position of the air supply port is definedby the intersection of a plurality of sets of boundary equations, the optimal air supply effect of the opening range of the air supply port is ensured in each set of boundary equations, and the air supply port structure with better air supply effect is finally designed by satisfying the boundary conditions of the plurality of sets of boundary equations.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a method for making an air supply port, a cylinder end cover and a rotary compressor. Background technique [0002] When the existing compressor is heating at low temperature, due to the low evaporation temperature of the refrigerant, the suction density is small, which leads to serious attenuation of the heating capacity of the compressor at low temperature. The common method to solve the low temperature attenuation of the compressor is the air supplement technology. [0003] There are single-stage air-enhancing technology and double-stage air-enhancing technology. Among them, the two-stage air supply technology is also called the two-stage enthalpy-increasing compressor, which has a good air supply effect, but the cost is high and the manufacturability is not good. In particular, the displacement of the two cylinders of the two-stage compression is only counted as the disp...
