Partition plate structure and compressor

Abstract

The invention discloses a partition plate structure and a compressor. The end face of a partition plate is provided with a composite hole groove, the composite hole groove comprises annular shallow grooves and dynamic pressure holes, the annular shallow grooves are formed at equal intervals with the axis of the partition plate as the circle center, and the dynamic pressure holes are communicated with the annular shallow grooves. The annular shallow grooves can increase the contact angle between oil drops and the solid end face, improve wettability between the oil drops and the solid end face, improve the adsorption capacity of an oil film on the end face of the partition plate and guarantee that lubricating media are not prone to loss. The dynamic pressure hole structure provides a sufficient dynamic pressure effect, the bearing capacity of a fluid film is improved, the composite hole groove structure can store lubricating liquid, the stored lubricating liquid can be extruded, carried or permeated to the matched surface along with shearing motion, the secondary lubricating effect is achieved, the composite hole groove structure can contain abrasive dust or impurity particles, and continuous abrasion of abrasive particles is prevented. The dynamic pressure holes are communicated with the annular shallow grooves, so that the lubricating oil film is quickly spread, sufficient lubricating oil is provided for the dynamic pressure holes, and the pressure of the oil film is increased.

Description

Technical field[0001]The present invention relates to the field of compressor, in particular a partition structure and a compressor.Background technique[0002]The end surface wear of the pump body is a common failure form of rotating compressors. For double cylinders or multi-cylinder compressors, the partition part is easy to lose due to lubrication, it is difficult to maintain a stable fluid lubrication state, especially by thermal elastic deformation. If the running gap is reduced, the lubricant is not enough, and the load capacity is limited. It is easy to cause the oil film to rupture discontinuous, forcing the end surface to quickly enter the mixed lubrication or boundary lubrication state, severe mechanical contact wear, material deformation stripping and other phenomena, and destroy compression Reliability and performance of the machine.Inventive content[0003]The present invention is directed to the above-mentioned deficiencies of the prior art, providing a separator structur...

[0002] The end face wear of pump body parts is a common failure form of rotary compressors. For double-cylinder or multi-cylinder compressors, it is difficult to maintain a stable fluid lubrication state due to the easy loss of the lubricating medium at the diaphragm part, especially affected by thermoelastic deformation, etc. , the running clearance is reduced, the lubricating oil is insufficient and the bearing capacity is limited, which can easily cause the oil film to break and be discontinuous, forcing the mating end face to quickly enter the state of mixed lubrication or boundary lubrication, resulting in severe mechanical contact wear, material deformation and peeling, and then destroying the compression machine reliability and performance
