Reasons for the oil leakage of the air compressor oil seal and the troubleshooting methods:
There are three main types of faults commonly encountered in the use of Dongguan Lingge air compressors: oil leakage faults, overheat faults and abnormal sound faults. The following classifications are analyzed and resolved.
Fault phenomenon: In the daily operation of the air compressor, the oil leakage phenomenon of the air compressor often occurs, and the surface has lubricating oil overflow.
cause of issue:
1. Stainless steel oil seals fall off or oil seal defects leak oil.
2. The loose spindle causes the oil seal to leak oil.
3. The joint surface leaks, and the inlet and return oil pipe joints are loose.
4. The belt is installed too tightly and the main shaft is worn.
5, casting or processing defects will also cause air compressor oil leakage.
Method of exclusion:
1. Lingge air compressor leaks oil, pay attention to observe the oil seal part, check whether the oil seal is cracked, whether the inner lip is cracked or flanging. One of the above conditions should be replaced; the valve  Imported pump  Industrial washing machine
2. Check whether the oil seal and the spindle joint surface are scratched or defective. If there are scratches and defects, it should be replaced.
3. Check whether the oil return is smooth, 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 diameter of the oil return pipe must be ensured, and the oil pipe is not twisted, bent, and the oil is smooth.
4. Check the oil seal and the matching size of the box, and replace it if it does not meet the standard.
5. Move the spindle to check whether the neck clearance is too large. If the clearance is too large, the air compressor bushing and oil seal should be replaced at the same time.
6. Check the sealing condition of each joint seal, repair or replace the gasket; check the inlet and return oil joint bolts and the box thread and tighten.
7. Check the oil leakage of the air compressor and re-adjust the tightness of the belt. It is advisable to press the thumb 10 mm.
8. Air compressor leakage, need to check the defects in the casting or processing of the box, repair or replace the defective parts 
The characteristics of rope core drill pipe are "three highs and one low", that is, high drilling speed, long life of diamond bit, high time utilization rate, low labor intensity of workers, so it is widely used in geological prospecting, coal field exploration and other fields. Among the whole set of drilling tools, the most important and most valuable is the drill pipe. The quality of the drill pipe is directly related to the use of the advantages of rope core drilling, and is also vital to the accurate acquisition of geological data and the control of drilling costs.
