The Multifaceted Role of Oil Injection Screw Compressors in Modern Industrial Operations

In the wave of modern industrial production, oil injection screw compressor, with its unique advantages, provides a strong guarantee for the continuous and stable operation of industrial production. It has become an indispensable and important equipment in many fields. This article will introduce the four roles of oil injection screw compressor.


When injecting oil, the oil mixes with the compressed gas in the form of micro-droplets, a huge heat exchange surface is formed, which rapidly absorbs the heat generated by the gas in the process of compression. Oil injection screw compressor effectively cools the compressed medium, so that the temperature of the exhaust gas is greatly reduced.


In the oil injection screw compressor, the friction between the two rotors is effectively lubricated due to the presence of a large amount of oil. What's more, the oil is identical to the lubricant used in the bearings, so there is no need for complicated seals to isolate the gas from the lubricant. This allows the distance between the rotor support bearings to be reduced, improving the stiffness of the rotor and reducing deformation.


Inside the oil injection screw compressor, there are multiple leakage channels, which often consist of narrow gaps. The presence of oil greatly enhances the sealing effect of these passages and significantly reduces the amount of leakage.

Noise Reduction

Due to the viscous nature of the injected oil, oil injected screw compressor has a good absorption and damping effect on acoustic energy and sound waves. Usually, after oil injection, the noise can be reduced by 10 to 20 decibels, which makes the equipment run more quietly.

In summary, oil injection screw compressor with its excellent cooling, lubrication, sealing and noise reduction performance, plays a pivotal role in industrial production. In the future, with the continuous progress of technology and the broadening of application areas, oil injection screw compressor will certainly show its strong vitality and broad application prospects in more fields.
