Garbage truck cylinder wear causes

Garbage engine cylinder wear is divided into normal wear and abnormal wear, the main reason for cylinder grinding into large and small, the upper working temperature is highest, and the oil film is not easy to form, the top of the lubrication is the worst, the main reason for uneven radial cylinder wear, Intake air blows and scours, the lubricating oil using the cylinder wall is diluted and forms more corrosive components, the engine cylinder will produce severe corrosive wear under conditions of low temperature and insufficient fuel combustion, and the engine coolant temperature is relatively high. When low or low temperature starts frequently, it is easy to produce more acidic substances.

The acidic substances are in direct contact with the garbage truck cylinder to form a thin layer of weakness. This thin layer is peeled off by a large and famous role, resulting in corrosive wear. The air entering the cylinder contains a lot of dust and causes severe abrasive wear, impurities in the engine oil, dust particles Such as a serious abrasive wear caused by the new or overhauled cylinder has not been run into the work directly, due to the uneven surface of the cylinder and the piston, wear each other to produce abrasive wear, in the cylinder surface parallel to the axis of the cylinder pull marks.

Adhesive wear , rubbish car cylinder and piston ring sliding in the case of poor lubrication, the direct friction between the metal surface between a very small part of the local high temperature, making it melt and stick, fall off, and gradually increase the adhesive wear, broken After the wear of the ring, the piston ring usually has 3-4 tracks. The first ring is easy to break. After the ring breaks, the lubrication condition of the second ring is destroyed, which intensifies the wear of the cylinder. If the oil is added, the pressure increases. It may be that the piston ring or cylinder bore is worn or damaged.
