Problems solved by technology

However, in the dry two-stage oil-free screw compressors on the market, although the compression cavity is not lubricated by oil, the bearings are still lubricated by oil, which cannot be completely sealed, and the overall energy efficiency of the host is also poor.

Abstract

The invention relates to a two-stage water spraying screw mainframe, which comprises an air cylinder. The air cylinder is provided with two independent and communicated compression cavities includinga primary compression cavity and a secondary compression cavity. The primary compression cavity is internally provided with an exhaust passage, the secondary compression cavity is internally providedwith an air suction passage, the wall of the air cylinder is provided with a nozzle communicated with an atomizing water cooling mechanism, and the nozzle is positioned between the exhaust passage andthe air suction passage and used for atomizing cooling. A gear box is mounted at air inlet ends of the primary compression cavity and the secondary compression cavity, and a gear mechanism with a spray lubricating effect is arranged in the gear box and connected with a rotor in one of the primary compression cavity and the secondary compression cavity. The two-stage water spraying screw mainframehas advantages that the mainframe integrally adopts a two-stage compression structure and is lubricated through water spraying, and energy saving and environmental friendliness are realized.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a two-stage water-spraying screw main engine. Background technique [0002] As people pay more and more attention to the concept of energy saving, two-stage screw extruders have become the mainstream trend. At present, the common two-stage screw main engine usually adopts oil injection lubrication, and it is impossible to obtain pure air energy when the oil and gas separation technology is not qualified. Due to the increasing demand for pure air power energy in the market, whether the oil-free quality of compressed air and the quality of air supply can be improved in the field of air compressor air supply has become a topic of our concern; especially in food, medical, textile , chemical industry, aerospace and other industries. However, in the dry two-stage oil-free screw compressors on the market, although the compression cavity is not lubricated by oil, the bearings are s...
