Oil pressure alarm is one of the most common but easily ignored alarms. Each time the engine is started, the oil pressure warning lamp will go out within 5 seconds. If it is always on or flashing, it indicates that there is a fault problem. However, because it will not immediately affect the normal operation of the excavator, many drivers directly ignore it.
Engine oil is mainly used to reduce the friction between the moving parts of the engine and ensure the flexible operation of the engine. This is the lubrication function. In fact, besides lubrication, engine oil also has many functions, such as cleaning, cooling, rust prevention, sealing, oxidation resistance, buffering, etc. Therefore, once the engine has an oil pressure alarm, if it is ignored, the engine will have a serious failure and will be scrapped. This article will summarize the causes of oil pressure alarm for reference.
1) When maintaining the engine and changing the oil filter, the oil output from the engine oil pump must first break through the air resistance because the oil filter is not filled with oil. Then it enters the oil pipe, enters the filter, and finally enters the main oil passage of the engine. In this process, the engine oil did not play the role of lubrication, cooling, sealing and cleaning, resulting in engine damage.
2) If the excavator is not maintained on time for a long time and the engine oil is not changed frequently, the engine oil pump will be seriously worn and lose the function of the oil pump, which will eventually lead to an alarm. At this time, the engine must be shut down for inspection. If it continues to be used, the engine will be seriously worn.
