Causes of air compressor running oil
1. Oil leakage in the pipeline: Check the pipeline and eliminate the fault.
2. Improper use of air pressure: For example, if you buy an 8kg air compressor, the actual air consumption is 5kg. During the operation of the air compressor, there is a one-time oversupply of air, and the oil leaks with the air.
3. Oil in the gas storage tank: Drain the gas storage tank to see if there is oil mixture.
4. Too much oil: the air compressor will overflow during the working process.
5. Poor quality of air compressor oil: low viscosity and poor filterability.
6. The minimum pressure valve malfunctions: the screw head is high temperature and high pressure, the oil and gas mixture quickly passes through the oil separation core, and the oil is running. Check the minimum pressure valve and eliminate the malfunction.
The choice of air compressor oil
Select the type of air compressor oil according to the design type of compressor oil, environmental conditions, and operating load. Generally, it is better to choose demulsibility and less residual carbon; pour point: ≤-10°C, flash point: ≥180 °C air compressor oil.
Under long-term high temperature environment (30℃), synthetic oil can be selected; low-viscosity compressor oil can be selected for high-speed water-cooled or low-pressure compressor with small compression ratio.
① The output power of the air-cooled piston shaft is 20KW, and the air compressor oil of 32, 46, 100 viscosity is selected.
②The water-cooled piston type uses 68 or 100 viscosity air compressor oil.
③Drip oil rotary type selects 100, 150, 220 viscosity air compressor oil.
④ 32-viscosity air compressor oil is selected for the injection rotary type.
