Four functions of oil injection in screw air compressor

1. Cooling action

The injected oil is in the shape of micro drop, mixed with the compressed gas, the huge heat exchange surface quickly absorbs the compressed heat of the gas, cools the compressed medium, and greatly reduces the exhaust temperature.Email:info@fntcompressor.com

2. Lubrication

In the dry screw air compressor, the two rotors do not contact with each other and rely on high-precision synchronous gear to maintain the clearance. In the oil injection compressor, there is a large amount of screw type air compressor oil, and the female rotor only absorbs a small part of the total power consumption of compression, so that the synchronous gear can be eliminated, so that the male rotor directly drives the female rotor.

In addition, since the injected screw type air compressor oil is exactly the same as the lubricating oil used in the bearing, it is no longer necessary to separate the gas from the lubricating oil with a set of complex sealing device, which will make the distance between the rotor support bearing smaller, significantly improve the rigidity of the rotor and reduce the deformation.

3. Sealing function

There are many leakage channels in the screw air compressor, these leakage channels are some narrow and long gaps, the existence of oil greatly strengthens the sealing effect, and the leakage through them will be greatly reduced.

4. Noise reduction

The injected oil is viscous fluid, which can absorb and damp the sound energy and sound wave. Generally, the noise can be reduced by 10 ~ 20 dB after injection.
