Oil injection, that is, in the oil injection screw In the compressor, a large amount of lubricating oil is sprayed into the compressed gas medium, which plays the role of lubrication, sealing, cooling and noise reduction. In an oil-injected air screw compressor, the output compressed air contains oil. ><:><:>

< r: :rrrrr r. >: >< >Principle of oil-injected screw compressor><:><:>
< r : :rrrrr r. >: >< >There is a pair of precision-machined female and male rotors that mesh with each other in the compressor casing. The motor drives the male rotor through the transmission device, and then the male rotor drives the female rotor. The compressor oil injected into the casing is mixed with air and is effectively compressed between the tooth grooves of the rotor. The main functions of oil in the body are: ><:><:>

There is no inertial force of reciprocating motion, and the dynamic balance of the rotor can be achieved. The vibration of the machine base is small, and there are no wearing parts such as valves and piston rings. It has a long operating life and simple maintenance and management. ><:><:>

) The lubricating oil is directly cooled to increase the compression ratio of each stage. ><:><:>
< r: :rrrrr r. >: >< >(>
) The lubricating oil injected can seal between the rotating bodies and between the rotating bodies and the box. As the cooling internal thermal expansion decreases, the gap is reduced, resulting in high efficiency at low speeds. ><:><:>
