What are the benefits of frequency conversion screw air compressor oil injection?
I have introduced a lot of basic knowledge about air compressors before, then the following editors of Wenzhou air compressors introduce the four major functions of screw frequency inverter air compressor oil injection:
(1) Cooling effect:
The injected oil is in the form of microdroplets, mixed with the compressed gas, and the extremely large heat exchange surface quickly absorbs the compression heat of the gas, which cools the compressed medium and greatly reduces the exhaust temperature.
(2) Lubrication:
In dry screw air compressors, the two rotors are not in contact with each other and rely on high-precision synchronous gears to maintain the gap. In the oil-injected air compressor, because there is a large amount of oil, and the female rotor absorbs only a small part of the total power consumption of the compression, the synchronous gear can be saved, so that the male rotor directly drives the female rotor. In addition, because the injected oil is exactly the same as the lubricating oil used in the bearing, it is no longer necessary to use a complex sealing device to separate the gas from the lubricating oil, which allows the distance between the rotor support bearings to be smaller and significantly improved The rigidity of the rotor is reduced, and the deformation is reduced.
(3) Sealing effect:
There are many leakage channels inside the screw air compressor, these leakage channels are some narrow gaps, the presence of oil greatly strengthens the sealing effect, so that the leakage through them is greatly reduced.
(4) Noise reduction effect:
The injected oil is a viscous fluid, which has absorption and damping effects on sound energy and sound waves. Generally, the noise can be reduced by 10-20 decibels after oil injection.
