The accessories for screw air compressor maintenance and replacement include air filter, oil filter, oil separator, and screw air compressor oil. How should we judge the quality of these accessories?
The air filter element can basically be seen. It mainly depends on the paper density and quality of the filter element. It can be seen with the naked eye. If the quality is not good, a large amount of impurities and dust will run into the inside of the screw compressor, which is easy to block the oil separator core, resulting in excessive internal pressure, causing the safety valve to open and spray oil.
The quality of the oil filter is not easy to identify. It mainly depends on the time of use. If the alarm is not blocked in advance at the specified time, or the oil pressure is low, and the exhaust temperature is too high, most of these are caused by the blockage of the oil filter. If the oil filter is of poor quality, it is also easy to cause failures in air compressor maintenance.
The oil-gas separator is also the most expensive consumable among the four. The reason why it is expensive is because of its high cost. The quality of imported oil-gas separators is relatively good. Its pressure difference ratio and oil filter are very good. Generally, replacing imported oil-gas separators basically guarantees that there will be no oil separator core failure.
Screw compressor oil is the lifeblood of the air compressor. Without good oil, the air compressor basically cannot operate. We all know that air compressor manufacturers do not produce screw compressor oil. Screw compressor oil is basically a kind of petroleum. There are three common grades of synthetic oil with 8000 hours, semi-synthetic oil with 4000 hours, and mineral oil with 2000 hours. Choosing good synthetic oil is more important for air compressors.
