Background
The single screw compressor is a meshing pair consisting of a cylindrical screw and two plane star wheels which are symmetrically arranged and is arranged in a shell. The screw groove, the inner wall of the shell (cylinder) and the star wheel tooth form a closed volume. The power is transmitted to the screw shaft, and the screw drives the star wheel to rotate. The gas enters the spiral groove from the gas suction cavity, and is discharged through the gas discharge hole and the gas discharge cavity after being compressed. The star wheel acts as a piston of a reciprocating piston compressor, and when the star wheel teeth move relatively in the screw grooves, the closed volume is gradually reduced, and the gas is compressed. Since the single screw compressor belongs to the positive displacement compressor, the gas is compressed against the change in volume between the star wheel and the screw. Because the meshing degree between screw rod and the star gear is very high, and in the compression process, star gear and helicobacter are in high-speed rotation state, consequently, must add lubricating oil between screw rod and the star gear, realize lubricating and cooling.
However, the lubricating oil is not required in all positions, for example, in the center of the meshing position of the star wheel and the screw, the required lubricating oil is more, the rest part of the lubricating oil is less in demand, and the required lubricating oil amount is changed according to different compressed gases, different compression flow rates, different compression pressures and the like. Therefore, the adjustment is needed according to the actual working condition, and the current single-screw compressor cannot achieve the purpose.
Therefore, there is a great need in the art for a more flexible oil distribution system.
