Description

Screw compressor

Technical Field

The utility model relates to a compressor technical field specifically relates to a screw compressor.

Background

A screw compressor cylinder is provided with a pair of intermeshing helical male and female rotors, both of which have a plurality of female teeth and which rotate in opposite directions. The clearance between the rotors and between the casing and the rotors is only 5-10 wires, the main rotor is driven by an engine or a motor, and the other rotor is driven by an oil film formed by oil injection of the main rotor or driven by synchronous gears at the ends of the main rotor and the concave rotor. There is theoretically no metal contact in the drive. The length and diameter of the rotor determine the compressor displacement and discharge pressure, with longer rotors giving higher pressures. The larger the rotor diameter, the greater the flow. The spiral rotor groove is filled with air when passing through the air suction port. When the rotor rotates, the rotor groove is sealed by the shell wall to form a compression chamber, and after the rotor groove is sealed, lubricating oil is sprayed into the compression chamber to play roles in sealing, cooling and lubricating. When the rotor rotates to compress the oil-gas mixture, the volume of the compression chamber is reduced, and the oil-gas mixture is compressed towards the exhaust port. When the compression chamber passes through the exhaust port, the oil-gas mixture is discharged from the compressor, and a process of suction, compression and exhaust is completed.

CN216131082U discloses a screw compressor, which comprises a main case and a motor casing, wherein a first screw and a second screw which are engaged with each other are arranged in the main case, a rotor is arranged in the motor casing, one end of the main case is connected with one end of the motor casing, the first screw and the second screw are arranged in parallel, the horizontal height of the first screw is higher than that of the second screw, and a shaft head of the first screw sequentially penetrates through the main case and is connected with the rotor.
