Sanitation garbage truck maintenance arm garbage truck engine maintenance skills
Before the maintenance of the arm dump truck engine, we must first understand its working conditions before maintenance of its important parts, especially the arm ring garbage truck engine piston ring, the general garbage truck piston ring sliding surface is most likely to wear The top dead center position of the cylinder is because the piston ring in the swing arm garbage truck engine under this condition breaks its oil film under the effect of high temperature gas and appears to be easily melted. This accelerates the piston ring in the swing arm garbage truck engine. Wear and tear.
The abrasion of the upper and lower end surfaces of the piston ring of the swing arm garbage truck engine is mainly due to the hard residue in the engine oil of the garbage truck and the mechanical grinding formed on the upper and lower end surfaces of the dust particles mixed in from the atmosphere, and is essentially abrasive wear. However, when the abnormal thermal deformation of the piston of the swing arm garbage truck engine occurs and the ring groove backlash becomes small, melt wear may also occur.
So how can we reduce the wear of the swing arm garbage engine piston?
There are many factors that affect the piston ring wear of the swing arm garbage truck engine, and these factors are often intertwined. In addition, the type of swing arm garbage truck engine and the use of different conditions, swing arm garbage truck engine piston ring wear is also very different, it can not rely solely on improving the swing arm garbage truck engine piston ring structure and material itself to solve the problem, mainly It can be started from the following aspects: materials and good matching of the piston ring and cylinder liner of the swing arm garbage truck engine; surface treatment; structural state; selection of lubricating oil and additives; cylinder liners caused by heat during assembly and operation; Swing arm dump truck engine piston deformation and so on.
There are many factors that affect the piston ring wear of the swing arm garbage truck engine. Among them, the material and shape of the swing arm garbage truck engine piston ring, the material and structure of the cylinder sleeve swing arm garbage truck engine piston, the lubrication state, the engine's structural form, operating conditions, Fuel and lubricant quality are the main factors. Of course, in the same cylinder, the effect of the lubrication state on the piston ring wear of the swing arm garbage truck engine is the largest. The ideal inter-ring lubrication is a uniform film of oil between the two sliding surfaces. However, this condition does not exist in fact, especially the first air ring, due to the influence of high temperature, it is difficult to establish a better lubrication state. .
At ordinary times, we must do a good job in the maintenance of the arm dump truck engine so as to avoid temporary failure of the swing arm garbage truck.
