Air compressor leakage fault diagnosis and troubleshooting

1. Air compressor leakage, pay attention to observe the oil seal location, check the oil seal for cracks, cracks or cuffs on the inner lip. If one of the above conditions should be replaced; check whether the oil seal and the spindle joint surface are scratched or defective, and the scratches and defects should be replaced. Check whether the oil return is unblocked, and the oil return is too smooth, so that the pressure of the crankcase is too high, causing the oil seal to leak or fall off. The minimum pipe diameter of the oil return pipe must be ensured, and the oil pipe is not twisted, bent, and the oil is smooth. Check the oil seal and the size of the cabinet. Replace it if it does not meet the standard.

2. Force the spindle to check if the neck clearance is too large. If the clearance is too large, the bearing bush and oil seal should be replaced at the same time.

3. Check the sealing of each joint seal, repair or replace the gasket; check the inlet and return joint bolts and the box thread and tighten.

4. Check the air leak of the air compressor and re-adjust the belt tightness. It is advisable to press the thumb 10 mm.

5. If the air compressor leaks oil, it is necessary to check the defects in the casting or processing of the box, and repair or replace the defective parts.

Overheat fault analysis

In the daily operation of the air compressor, the air compressor overheating failure may occur due to the long-time overload operation of the air compressor.

Air compressor overheating failure phenomenon:

1. The air compressor exhaust temperature is too high.

2. The operating part is hot.
