Function of lubricating and coolant oil for air compressor.
– Cooling: air when compressed to high pressure creates a huge amount of heat. Oil has a partial cooling effect for the generated compressed air. This heat then follows the oil to the cooler for cooling.
– Lubrication: oil used to lubricate gears, transmissions in air compressors.
– Sealing (sealing): for oil-based machines, there is a certain clearance between the screw pairs. Air compressor oil has the effect of sealing this gap, preventing pressure from bouncing back into the compression chamber.
– Cleaning: the oil will wash away some of the dust in the compressed air. Effects of using non-genuine air compressor oil
– Poor quality oil has very poor heat exchange which makes the cooling process in the air compressor inefficient. Leads to overheating and possibly sudden shutdown.
– Oil is quickly scaled and glued to the compression assembly. Reduces the life of gears, compression chamber.
– Imitation oil is usually very liquid, easy to evaporate when the temperature is too high. The amount of oil is quickly depleted, so it is not time for you to buy more oil.
– Liquid oil should reduce the ability to gas the screw pair. This leads to a decrease in compression efficiency.
Conclude
– The use of fake oil, of unknown origin will reduce the life of the air compressor, and the quality of the compressed air will be poor. And the fact that you have to buy a new air compressor is just a matter of time.
