Oil-injected screw air compressor is a kind of screw air compressor, and what is the difference between oil-injected screw air compressor and ordinary air compressor?
In fact, the oil-injected screw air compressor can be understood as a feature-enhanced version of ordinary air compressors. When many companies purchase and use air compressors, they have various element conditions for the air compressor equipment based on production conditions, or mute noise reduction or It is because the operating environment temperature affects, etc., when ordinary air compressors can no longer meet the needs of customers under such individual factors, and at this time, the oil-injected screw air compressor is the right choice.
Ingersoll Rand's oil-injected screw air compressors mainly provide enhanced solutions for the four major functions of cooling, lubrication, sealing, and noise reduction.
Features of the four main functions of Ingersoll Rand's oil-injected screw air compressor:
1. Sealing function: There are many leakage passages inside the Ingersoll Rand screw air compressor, these leakage passages are some long and narrow gaps, the existence of oil greatly strengthens the sealing effect, making the leakage through them large cut back.
2. Cooling effect: The injected oil is in the form of droplets and is mixed with the compressed gas. The large heat exchange surface quickly absorbs the compression heat of the gas, cooling the compressed medium and greatly reducing the exhaust temperature.
3. Noise reduction effect: The injected oil is a viscous fluid, which can absorb and dampen sound energy and sound waves. Generally, the noise can be reduced by 10-20 decibels after fuel injection.
4. Lubrication: In the dry screw compressor, the two rotors do not contact each other, and the gap is maintained by high-precision synchronous gears. In the oil-injected compressor, because there is a large amount of oil, and the female rotor only absorbs a small part of the total power consumption of compression, the synchronous gear can be omitted, and the male rotor can directly drive the female rotor. In addition, since the injected oil is exactly the same as the lubricating oil used in the bearings, it is no longer necessary to use a complex sealing device to separate the gas from the lubricating oil. This makes the distance between the rotor support bearings smaller and significantly improved The stiffness of the rotor is improved, and the deformation is reduced.
