Wrong practices in the use and maintenance of the dredger will damage the dredger and threaten its personal safety, resulting in dredger performance degradation, accelerated wear (a basic type of component failure), and shortened life span. The dredger has overfilled with oil. When the dredger's oil is insufficient, poor lubrication of bearings and journals will occur, aggravating wear (a basic type of component failure) and even causing bush-burning accidents. But with too much oil, the engine will also fail, that is, the crankshaft handle and the big end of the connecting rod will be violently agitated during work, which will increase the internal power of the dredger's engine (referring to how much work the object does in a unit of time ) Loss will increase the oil splashing on the cylinder wall and cause the failure of burning and draining oil. Therefore, the oil should be controlled between the upper and lower markings of the oil dipstick. The quality of the lubricating oil of the dredger is directly related to the length of the engine life cycle. New-type dredgers have very strict requirements on lubricating oil. The choice of lubricating oil and how to replace it should be carried out in accordance with the manufacturer's regulations. When selecting engine oil, both the quality level and the viscosity level must be paid attention to. First of all, the performance level should be selected according to the compression ratio and displacement. Then select the viscosity level according to temperature and load. Good engine oil can ensure good engine lubrication, reduce wear (a basic type of component failure), reduce maintenance frequency and difficulty, and increase the service life of the dredger. When the dredger chooses the oil viscosity, it should try to use low-viscosity lubricating oil under the condition of ensuring the lubrication and sealing of the engine.
