Description

Technical Field

[0001] The utility model relates to the technical field of screw compressors, in particular to an open type novel screw compressor unit. Background Art

[0002] The open screw compressor is a compression device with a specific structure. Its main features include a pair of male and female rotors that compress the gas, and no suction and exhaust valves are set at both ends of the cylinder. The gas output is regulated by the oil piston controlled by oil pressure pushing the slide valve. The main function of the balance piston is to balance the axial force on the male rotor to prevent its axial movement. In addition, the oil injection hole on the slide valve will spray lubricating oil to achieve cooling, lubrication and sealing during the compression process.

[0003] When the existing screw compressor is in use, the vibration of the screw compressor during operation is one of the problems that often occur during the operation of the screw compressor, which may not only affect the stability and efficiency of the compressor, but also cause damage to its internal components. In addition, due to the large size of the screw compressor, it is not convenient to move it. Utility Model Content
