The oil circuit system of the screw compressor is sealed very tightly, and under normal circumstances there will be no oil leakage fault, but when the maintenance is not enough or accidents occur in the process of operation, there may be oil leakage.The phenomenon of oil leakage also has a variety of, one is seepage oil, oil leakage is very slow;One is oil leakage, faster;The other is oil injection, which is almost instantaneous.No matter what kind of fault can not be ignored.
Screw compressor oil leakage fault is divided into three: oil seepage, drop oil and spray oil, for these three conditions according to different phenomena to make different treatment.So, when you find that the machine leak, do not rush to repair, but should find out the cause of the leak, and then repair.
In the case of oil seepage, if the reason is not caused by more complicated factors, but only due to loose or poor tightening of the connection part or increased pressure, the connection part can be tightened for a while under the stop state.
In the case of dripping oil, the treatment method is basically the same as that of oil infiltration.However, if there are deep-seated reasons, we must eliminate the hidden dangers according to the deep-seated reasons before dealing with them.
In the case of oil injection, it is generally because the oil cooler of the screw compressor is blocked.The method is to take out the core of the oil cooler, put it in the iron trough, fill the water with scale-removing agent, soak in the water for 1 ~ 3 days, and then take out the core of the cooler, with soft copper wire will be in the core of the cooler scale one by one dredge open.
When the cooler core is dredged, the whole oil system is cleaned.The method is to connect the oil system with pipe fitting and the cleaning pump truck to form a self-circulation system.The cleaning pump truck we use is an iron box more than one meter square. It is equipped with a trolley wheel that can be pushed to move the box freely and push it to the front of the compressor when using it.A pressurized water pump and an electric heater are set up to pour the detergent into the water in the iron tank. The water pump is started and the detergent starts circulating in the oil road system. After 1 ~ 3 days of immersion, the dirt of the oil road system is cleaned.
