How to avoid air compressor oil leakage

1. Air compressor working environment The location of air compressor work requires less dust, clean air and good ventilation. Dust, particles and other impurities in the air entering the air compressor system will chemically react with the lubricating oil, resulting in carbon deposits and sludge. For example, cement, coal, textile and other industries must do a good job of air filtration, as well as "three filters and one oil" timely maintenance and replacement.

2. The air filter with low precision and poor filtration precision will make some dust particles in the air unable to be intercepted, and will directly enter the air compressor system, causing excessive oil filter and oil load, resulting in blockage. Impurities, oil oxides, worn metal particles, etc. entering the air compressor system are partially intercepted on the oil filter layer due to poor oil filtration accuracy, and the other impurities have been circulating in the machine until they rise to the oil content. After separation, they stay in the oil content. In the filter layer, the oil and gas separator is blocked prematurely.

3. The lubricating oil with low quality and poor oxidation resistance is not suitable for use. Even if the working time is short, it will produce carbon deposits and jelly, which will block the oil.

4, different oil mixed use Do not mix different grades, different types of air compressor lubricating oil phase. Do not mix compressor lubricants from different manufacturers.

5. Excessive moisture in the filter material. Excessive moisture in the oil filter material causes the filter material to swell and shrink its pores, reducing the effective separation area of the oil, resulting in increased oil resistance and early blockage by the Ness oil and gas separator.

6. Running in a harsh environment The operating environment will affect the actual working conditions. Long-term operation under high temperature, high humidity or high pressure will speed up the replacement cycle of the three filters and lubricating oil.

1. avoid blocking of the one-way valve and vent valve. If the one-way valve and vent valve are blocked, the temperature in the box shell will rise, and the oil and gas will fill the entire space, which will increase the pressure in the box shell and increase the movement resistance of the piston. The fuel consumption increases. At the same time, due to the air pressure difference between the inside and outside of the box shell, it often causes weak sealing and oil leakage.

It is 2. to ensure that the pipe nuts used for sealing engineering machinery of various oil pipe joints are often disassembled and assembled, which are easy to loosen due to the breakage of sliding wires. For example, poor precision of bell mouth of two joints, misalignment of center lines of two conical surfaces or different conicity will cause oil leakage. The grinding method can be used to repair the cone seal, so that the nut is tightly sealed and reliable.

3. correctly install the gasket between the air compressor accessories plays a leak-proof sealing function. If the material, production quality and installation do not meet the technical specifications, oil leakage can be caused.

4. if the nut is tightened correctly, too loose will cause the lining to leak, and too tight will cause the metal around the screw hole to bulge, or the screw thread will slip and cause oil leakage.

5. Replace the failed oil seal in time. Many parts of the oil seal on the air compressor will be thrown away due to improper installation, causing the journal and the oil seal edge to be different. Some oil seals will lose their elasticity due to rubber aging after being used for too long.

6. Replace the worn parts in time. The air compressor parts are worn too much after use, causing high-pressure gas in the combustion chamber to escape into the crankcase, forcing the oil to leak.
