Embodiment Construction

[0038] Such as Figure 1-8c As shown, the present invention provides a compressor main shaft, which includes a main shaft center hole 1 that is opened in the axial direction and can allow back pressure oil to flow through, and communicates with the main shaft center hole 1 in the radial direction. The main shaft radial oil hole 2, the main shaft radial oil hole 2 is used to deliver the oil out of the main shaft 5 to provide the required back pressure and lubrication;

[0039] An oil plug 3 is arranged on the upper part of the spindle center hole 1, and a valve assembly 4 is also arranged in the spindle center hole 1 between the oil plug 3 and the spindle radial oil hole 2 , the upper end of the valve assembly 4 is connected to the oil plug 3;

[0040] The valve assembly is configured such that when the oil pressure in the central hole of the main shaft is greater than the back pressure provided by the valve assembly, the valve assembly opens to allow oil to flow from the cent...

Abstract

The invention provides a compressor spindle and a compressor with the compressor spindle. The compressor spindle comprises a spindle center hole (1) located in the axial direction in the compressor spindle and a spindle radial oil hole (2) communicating with the spindle center hole (1) in the radial direction. An oil plug (3) is arranged at the upper portion of the spindle center hole (1), and a valve assembly (4) is arranged in the spindle center hole (1) and located between the oil plug (3) and the spindle radial oil hole (2). The valve assembly is arranged in the manner that when the oil pressure in the spindle center hole is larger than the backpressure supplied by the valve assembly, the valve assembly is opened so that oil can be allowed to flow to the oil plug (3) from the spindle center hole; and when the oil pressure in the spindle center hole is smaller than the backpressure supplied by the valve assembly, the valve assembly is closed so that oil can be prevented from flowing to the oil plug (3) from the spindle center hole. Through the compressor spindle and the compressor with the compressor spindle, under the situation that the rotation speeds of the spindle are not consistent, the backpressure of backpressure oil finally entering the spindle radial oil hole can reach stability, and backpressure fluctuation cannot be generated.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a compressor main shaft and a compressor with the same. Background technique [0002] At present, in the back pressure oil circuit of the traditional sliding vane compressor, the back pressure oil enters the center hole of the main shaft through the oil pump at the bottom of the pump body, and the oil entering the center hole of the main shaft enters into the center hole of the main shaft by the centrifugal force brought by the rotation of the main shaft. The radial oil hole finally enters the back pressure groove of the slide through the clearance channel to provide back pressure for the slide, and an oil plug is installed on the upper end of the center hole of the spindle to control the flow of oil outlet, which can prevent oil from directly flowing from the upper end of the center hole of the spindle to a certain extent. drain. [0003] However, since the oil ...
