The invention provides and discloses an oil-free lubrication two-stage scroll compressor. Scroll teeth of fixed scroll plates and scroll teeth of moving scroll plates are each of a single-scroll-tooth structure, and cooling fins are distributed on the opposite faces. Solid self-lubrication friction pairs are additionally mounted at the tops of the scroll teeth of the fixed scroll plates and the tops of the scroll teeth of the moving scroll plates. A small crank throw rotationally moving is mounted on a tray and provided with a self-lubricating sealing bearing. The moving scroll plates do plane motion between the fixed scroll plates and support bodies. A spindle is connected with a steering box. The centers of the moving scroll plates are connected with a transmission shaft in the steering box. The moving scroll plates are driven by the transmission shaft to rotate, and gas sequentially passes through a left compressor body and a right compressor body. The oil-free lubrication two-stage scroll compressor has the beneficial effects that the compression ratio is increased, no lubrication oil is contained in a compression cavity of the compressor, and the requirement of the food medical field for the compressor is met.
Description
technical field [0001] The invention belongs to the technical field of compressors, and relates to an oil-free two-stage scroll compressor. Background technique [0002] At present, compressors for air transportation used in food, medicine and other fields must meet the following conditions: the compressor has a small size and light weight; the displacement is large; the gas to be transported does not contain lubricating oil. At present, lubricating oil is needed in the compression chamber of most compressors for lubrication, so that there is a small amount of lubricating oil in the conveying gas. [0003] The oil-lubricated scroll compressors in the prior art have the following disadvantages: 1) the pressure of the compressed gas is not enough, that is, the compression ratio is not enough; 2) the compressed gas must be in contact with lubricating oil, and the compressed gas must be transported. Contains lubricating oil; 3) Adding auxiliary machines in the compression syste...
