Overview
The problem of oil leakage in the air compressor is inevitable. Once discovered, it must be dealt with in time. The oil leakage of the air compressor unit will bury hidden fire hazards.
Four General Solutions for Oil Leakage of the Compressor Air Tubing – Air Hose
(1) Shut down the system for maintenance and replace the related spare parts;
(2) Adjust the process plan to reduce the pressure in the fuel tank;
(3) Take measures to repair and plug the leaking parts, and the common use is the mining technology;
(4) Purchase a new compression cylinder for replacement;
Purchasing a new compression cylinder is among the most time-consuming and cost-prohibitive methods, which not only puts pressure on the production unit’s budget but also affects the unit’s normal operation.
The oil return pipe in the air compressor accessories is connected with a cooler. It is necessary for the condensed lubricating oil in the oil-gas separation filter element to be led by the oil return pipe to the air inlet cavity of the machine head in time to prevent the separated oil from entering the pipe network system with compressed air.
In order to prevent the oil and gas in the air end from flowing back through the oil return pipe during the shutdown, a check valve is installed in the oil return pipe. There is a throttle hole on the one-way valve to prevent a large amount of compressed air from following the lubricating oil from the oil and gas tank into the air inlet cavity of the machine head through the oil return line. The diameter of the orifice is generally 0.5~1mm, which is very sensitive to dirt. Once blocked, it will cause a large amount of oil in the exhaust.
Once the exhaust gas is found to contain abnormal oil, the temperature of the oil return pipe should be checked first. If the temperature of the oil pipe is close to normal temperature, it indicates that the oil return pipe is blocked. Above the oil and gas separator is the oil return pipe. It is to return the oil inside the oil component to the nose. Otherwise, the exhaust port will run out of oil.
