Description

Buffer tank of dry-type oil-free screw rod compressor

Technical Field

The utility model belongs to the technical field of a helical-lobe compressor technique and specifically relates to a dry-type does not have oily hob compressor buffer tank.

Background

The first oil-free screw compressor in the world in 1956 appeared that the medium in the compression cavity of the oil-free screw did not contact with lubricating oil, so the compressor was called "oil-free screw". Because the compression chamber is dry, it is also referred to as a "dry screw". The dry type screw compressor is still classified as an oil-free screw due to the structural characteristics of the oil-free screws such as ' non-contact between a male rotor and a female rotor ', ' driving of the screw by a synchronous gear ', ' separation of oil in a gear box from liquid in a compression cavity ', and the like, but the characteristic that the gas medium of the compressed gas is not in contact with any other medium ' which is the most important characteristic of the dry type screw compressor is lost functionally. The liquid injected into the compression chambers acts as a lubricant, seal, cooling and noise reduction. Of course, under the condition that "the liquid medium does not react with the medium to be compressed", the cost of the liquid jet compressor is relatively low compared with that of a dry screw, and therefore, the liquid jet compressor is widely used in some domestic fields. In the prior art, the gas containing dust and the gas carrying water vapor in the buffer tank enter the screw compressor to cause damage to the normal operation of the compressor. Therefore, a dry-type oil-free screw rod compressor buffer tank is provided.
