Abstract
The invention relates to an oil spray type double-screw compressor, in particular to a spiral rotor and an oil-gas separating cavity inside the oil spray type double-screw compressor. A screw cavity of a compressor body of the double-screw compressor is connected with the oil-gas separating cavity through an exhaust port in an end cover. According to the rotor in the screw cavity, two needle bearings are used for bearing radial force, and an angular contact ball bearing is used for bearing axial force. A reduction gearbox is installed at the end of the screw cavity, and two end covers are installed at the other side of the screw cavity, wherein the end cover close to the screw cavity is used for sealing of the screw cavity and installation of the bearings, and the end cover at the outer side is used for sealing an oil path and extracting an oil-gas mixture. A filter plate used for filtering the oil-gas mixture is installed on the middle-lower portion inside the oil-gas separating cavity. A one-way exhaust valve and an electromagnetic valve are installed on the upper portion of the oil-gas separating cavity, wherein the exhaust valve is used for exhausting the gas, and the electromagnetic valve is used for controlling oil spraying. According to the compressor cavity of the oil spray type double-screw compressor, the size of the compressor is greatly reduced. The double-screw compressor is analyzed, simulated and verified through fluid dynamics by means of software, and a solid theoretical foundation is achieved.
