Description

Integrated screw medium-pressure air compressor for water chiller

Technical Field

The invention relates to the technical field of air compressors, in particular to an integrated screw medium-pressure air compressor for a water chiller.

Background

Screw compressors are also known as screw compressors. The screw compressor cylinder is provided with a pair of intermeshing helical male and female rotors, both of which have a plurality of concave teeth and rotate in opposite directions. The clearance between the rotors and between the casing and the rotors is only 5-10 filaments, the main rotor (also called male rotor or male rotor) is driven by an engine or a motor (mostly driven by the motor), and the other rotor (also called female rotor or female 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 female rotor. There is no metal contact in the drive (theoretically). The length and diameter of the rotor determine the displacement (flow) and discharge pressure of the compressor, and the longer the rotor, the higher the pressure; the larger the rotor diameter, the greater the flow. The working cycle can be divided into three processes of suction, compression and exhaust. As the rotor rotates, each pair of intermeshing teeth successively completes the same duty cycle.
