Oil-free lubrication whirlpool compressor

Abstract

The non- oil lubrication vortex compressor, its goal is in can relatively move with the gas contact rubs vice- center, through installs self lubrication the compression, reduces in the gas loading system to have the separator and so on other supporting facilities, causes the oil duct system to change simply, vortex line the addendum and on the static vortex ledger wall installs in the rotation vortex between has by self lubrication the material constitution packing, is equipped with the ring-like packing in the rotation vortex ledger wall edge and between the static vortex lower extremity, installs between the rotation vortex rear end board and the support body has 2 packing rings which constitutes by self lubrication the material. Installs in the rotation vortex front end board and between the static vortex in end surface has the ring-like packing which constitutes by self lubrication the material.

Description

technical field [0001] The invention relates to a scroll compressor in a fluid displacement machine, which can realize oil-free lubricated compression of gas, and is mainly used in the compression of special media and the compression of ordinary media in special requirements. Background technique [0002] Oil-free scroll compressor means that there is no lubricating oil in the compression chamber. The relative sliding motion of the dynamic and static scrolls is lubricated by solid self-lubricating materials, while transmission mechanisms such as crankshaft bearings still rely on lubricating oil to achieve real-time lubrication; that is, the compressed gas does not come into contact with the lubricating oil to ensure that the compressed air is not in contact with the lubricating oil. The gas is clean. [0003] The oil-lubricated scroll compressors are more common in the prior art. The oil-lubricated scroll compressors have the following disadvantages: 1) The compressed gas m...

Problems solved by technology

[0003] The oil-lubricated scroll compressors are more common in the prior art. The oil-lubricated scroll compressors have the following disadvantages: 1) The compressed gas must be in contact with lubricating oil, and the compressed gas must contain lubricating oil. Oil, which limits the application field of the scroll compressor; 2) Increase the auxiliary machine in the compression system, such as adding an oil-gas separator; 3) The lubricating oil contained in the compressed gas condenses on other equipment in the compression system, Affect the normal work of other equipment

If the lubricating oil condenses on the tube wall of the cooler, it affects its heat exchange efficiency; 4) It makes the oil supply system of the compressor complicated and increases the oil path leading to the compression chamber
