Problems solved by technology

Regardless of the oil supply method and circulating oil circuit, it is necessary to ensure sufficient oil flow to lubricate and cool the bearings. Due to the limitations of the space and structure of the compressor and design restrictions, the compressor lubrication system usually has complex structures, low efficiency, and low cost. High, poor lubrication effect, additional increase in compressor power consumption and other issues

Abstract

The invention discloses an oil way of an oil-free dry type screw compressor and the oil-free dry type screw compressor comprising the oil way. The oil way of the oil-free dry type screw compressor comprises a gearbox shell, a gearbox, a cylinder body seat and a front cover plate, wherein an oil bin is arranged in the gearbox, an oil pump is arranged in the gearbox shell, first oil outlet pipes are arranged on two sides of the oil pump, one end of each first oil outlet pipe is connected with the oil pump, the other end of each first oil outlet pipe is connected with the oil bin, first oil inlet pipes corresponding to the first oil outlet pipes are arranged on the gearbox, second oil outlet pipes are arranged at the other end of the gearbox, third oil inlet pipes corresponding to the second oil outlet pipes are arranged on the cylinder body seat, an oil return pipe is arranged at the other end of the cylinder body seat, and the oil return pipe is connected with the oil bin. The technical scheme has the advantages that the structure is simple, the lubricating and cooling effects are good, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of oil-free dry screw compressors, in particular to an oil circuit of an oil-free dry screw compressor and the oil-free dry screw compressor. Background technique [0002] Oil-free dry screw compressors usually need lubricating oil to lubricate the bearings and gears. The bearings usually rely on the pressure difference between suction and exhaust to supply oil, or use an external oil pump to force oil supply, and then send the oil to each part through the external or internal circulating oil circuit. Bearing lubrication points. Regardless of the oil supply method and circulating oil circuit, it is necessary to ensure sufficient oil flow to lubricate and cool the bearings. Due to the limitations of the space and structure of the compressor and design restrictions, the compressor lubrication system usually has complex structures, low efficiency, and low cost. High, poor lubrication, additional increase in co...
