Embodiment 1

[0034] Such as figure 1 As shown, the present invention provides a horizontal rotor compressor, which is mainly composed of a motor 3, a crankshaft 2, a low-pressure stage (compressed by a low-pressure cylinder 11), a high-pressure stage (compressed by a high-pressure cylinder 9), an upper flange 8, a sealing structure 19, a lower Flange 12 (including medium-pressure chamber 23), lower flange cover plate 13, enthalpy-increasing air supply structure, shell sealing structure, and liquid separator components. The liquid distributor part is fixed on the shell assembly by welding, the low-pressure cylinder 11, the lower flange 12 and the lower flange cover plate 13 are connected in sequence and centered with screws, the suction elbow of the liquid distributor part and the suction chamber of the low-pressure cylinder 11 Connected; the high-pressure cylinder 9, the upper flange 8 and the upper muffler 7 are connected in sequence and centered with screws, the sealing structure 19 is i...

Embodiment 2

[0042] Such as figure 2 , this embodiment is a further improvement made on the basis of Embodiment 1. Preferably, the oil stabilizing channel 17 is arranged on the upper flange 8 and runs through the upper flange 8 along the axial direction. The upper flange 8 is located below the axis of the upper flange 8 . The upper flange is a structure with an axis, and when it is installed, the axis coincides with the axis of the crankshaft. The purpose of oil supply and oil guide can be effectively realized by connecting the oil stabilizing channel through the upper flange, so that the refrigerant oil can pass through from the high pressure chamber side according to the pressure difference. The oil stabilizing channel is pressed into the low-pressure chamber side, and the position of the oil stabilizing channel is set to be located below the axis of the upper flange, that is, on the negative Y axis in the vertical direction of the horizontal compressor, so that the position of the oil ...

Embodiment 3

[0045] Such as Figure 4 , this embodiment is a further improvement made on the basis of Embodiment 1 and / or 2, preferably, it also includes a lower flange 12 and a lower flange cover plate 13, and on the lower flange cover plate 13 A first enthalpy-increasing air hole 20 is opened, and a medium-pressure chamber 23 is provided on the lower flange 12, so that the gas in the low-pressure chamber 15 can enter the medium-pressure chamber through the first enthalpy-increasing air hole 20. cavity 23. By opening the first enthalpy-increasing gas supply hole on the lower flange cover plate, the medium-pressure gas supplemented into the low-pressure cavity through the gas-supplementing enthalpy-increasing pipeline 16 can be effectively guided to the medium-pressure cavity on the lower flange, so that It is mixed with the medium-pressure gas compressed from the low-pressure cylinder, and then enters the high-pressure cylinder to complete the process of replenishing gas and increasing e...

Abstract

The invention provides a horizontal rotor compressor comprising a shell (22), a motor (3), an upper flange (8), a seal structure (19), a gas supplementing and enthalpy increasing pipeline (16) and an oil stabilization channel (17). The upper flange (8) is arranged on the high-pressure side of the compressor. The seal structure (19) is arranged between the upper flange (8) and the shell (22). A cavity of the shell (22) is divided into a high-pressure cavity (4) and a low-pressure cavity (15), wherein the high-pressure cavity (4) and the low-pressure cavity (15) do not communicate. High-pressure exhausted gas of the compressor communicates to the high-pressure cavity (4). Medium-pressure gas outside the compressor communicates to the low-pressure cavity (15) through the gas supplementing and enthalpy increasing pipeline (16). The oil stabilization channel (17) is arranged on the upper flange (8) and allows oil to communicate to the low-pressure cavity (15) from the high-pressure cavity (4). By means of the horizontal rotor compressor, the required high and low pressure difference can be formed on the two sides of the upper flange, oil can smoothly flow to the side of the low-pressure cavity from the side of the high-pressure cavity, the oil can be effectively supplied to the internal structure of the compressor, meanwhile, the existing situation of small-interval throttling is further overcome, the throttling loss is prevented, and the energy efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a horizontal rotor compressor. Background technique [0002] At present, the horizontal rotor compressors used in the fields of refrigeration, small refrigerators, and vehicle air conditioners mainly adopt an oil baffle at the exhaust muffler, so that the oil baffle forms a small gap with the upper flange or the inner wall of the housing to throttle the flow. , under the action of the oil baffle at the upper muffler, a pressure difference is formed, so that a high-pressure chamber is formed on the motor side, so that the pressure on the motor side is higher than the pressure on the lower cover side, and the refrigerant oil passes through the bottommost gap in the vertical direction of the oil baffle from the high pressure chamber. The side flows to the low-pressure side to ensure the oil level and stabilize the oil supply system. However, the structure of the oil baffle caus...
