ChineseIn the daily operation of the air compressor, the air compressor often leaks oil, and there is lubricating oil spilling on the outside. The reasons for the oil leakage of the air compressor are as follows:
1. The oil seal falls off or the oil seal is defective and leaks oil
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, causing the main bearing bush to wear
5. Casting or machining defects can also cause oil leakage in the air compressor
Judgment and troubleshooting methods of air compressor oil leakage failure:
Judgment and troubleshooting methods of air compressor oil leakage failure:
1. If the air compressor leaks oil, pay attention to observe the oil seal, check whether the oil seal is cracked, and the inner lip is cracked or flanged by mistake. 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 unblocked. If the oil return is not smooth, the crankcase pressure is too high and the oil seal is caused. If the oil leaks or falls off, the minimum diameter of the oil return pipe must be ensured, and it is not twisted or bent, and the oil returns smoothly. Check the oil seal and the matching size of the box. Replace if it does not meet the standard.
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 the oil leakage of the air compressor and readjust the tightness of the belt. It is advisable to press 10 mm with the thumb; if the air compressor is leaking, it is necessary to check the box casting or processing defects, repair or replace the defective parts.
