Trouble phenomenon: Lubricating oil overflows on the outside of the air compressor.
cause of issue:
1. The oil seal is off or the oil seal is defective and leaks.
2. The main shaft is loose and the oil seal leaks.
3. Leakage of the joint surface, loosening of the oil inlet and return pipe joints.
4. The belt is installed too tightly and the main bearing bush is worn out.
5. Casting or processing defects.
Fault judgment and troubleshooting methods:
1. For the oil seal, check whether the oil seal is cracked, whether the inner lip is cracked or flanged. If there is one of the above conditions, it should be replaced; check whether the joint surface of the oil seal and the main shaft is scratched or defective. If there are scratches or defects, it should be replaced. Check whether the oil return is unobstructed. If the oil return is not smooth, the crankcase pressure is too high and the oil seal leaks or falls off. The diameter of the return pipe must be ensured, and the return pipe must not be twisted or bent, and the oil return is smooth. Check the matching size of the oil seal and box body, and replace those that do not meet the standards.
2. Move the main shaft forcefully to check whether the neck gap is too large. If the gap is too large, replace the bearing bush and oil seal at the same time.
3. Check the sealing conditions of the gaskets of each joint, repair or replace the gaskets; check and tighten the bolts of the oil inlet and return joints and the box body threads.
4. Check and re-adjust the tightness of the belt. It is advisable to press down 10 mm with your thumb.
5. Check the casting or processing defects of the box body (such as whether the oil return hole at the box body installation is unblocked), repair or replace the defective parts.
