Cummins Engine Parts Daily Management and Maintenance Considerations

Cummins engine performance is stable, low maintenance rate, has been the main engine of large trucks. Scientific management and use to enhance engine performance, extend engine life plays an important role, this article will introduce you to how to carry out scientific, lean management and maintenance of Cummins engine parts, in order to optimize engine performance.

1.Cooling system

Cummins engine, as the core part of the main transportation equipment in the mine, is often in a high power state when working, therefore, the engine requirements are very high. The high utilization rate of long-time full-load operation makes the cooling system of the engine extremely strict, so we require that the cooling system of the engine must be highly efficient in heat dissipation.

In the selection of coolant, should not use natural water and mineral-containing groundwater, so as to ensure that the engine cooling system less corrosion, less scaling, keep smooth, keep cool. Such as the use of low-quality coolant, the cooling system will produce scaling, affecting the coolant cycle, blocking the radiator cooling water pipe. Theoretically, it is necessary to use softened distilled water. Now all seasons with antifreeze, the more ideal is to use four preventive agents, that is, anticorrosion, anti-scaling, anti-freezing, anti-bursting, and then to meet the cooling needs of the engine, antifreeze should not be reused, if reused, it must be filtered and then refilled.

In order to ensure adequate heat dissipation, it is necessary to choose the engine water tank with a large cooling area, as well as a good quality fan, for the use of fan shafts and bearings, need to be carefully selected. In addition, Cummins engine are monoblock cylinder head, due to the mining equipment operating conditions are harsh, dirt and dust, such as dirt and dust attached to the external surface of the engine, will seriously impede the engine block heat dissipation. In order to ensure that the engine block is clean and dissipate heat, the engine must be cleaned in a timely manner at low temperatures to ensure that the engine is clean.

2. Air intake system

Inspection of suction pipe. Mining road surface is characterized by insufficient flatness, trucks run inevitably bumpy, very easy to cause the suction pipe card loose into the ash. For this reason, firstly, we should ensure that the deck platform is firm, such as the deck crosstalk, the suction pipe will produce tensile force, resulting in the loosening of the pipe card, rubber sleeve damage. Second, use reliable quality suction sleeve to prevent cracks into the ash. Third, the suction system for testing, the method is, the engine at a low idle speed 750 r/min running conditions, in the dust into the tube card at the injection of ether, such as engine speed is stable and unchanged, it is shown that the suction pipe closed well, such as the engine speed fluctuations, it shows that the ether into the engine here, then the dust may also be entered, it must be refurbished.

The supercharger is vital to the normal operation of the engine, and the life of the supercharger depends mainly on the pressure and flow of the lubricating oil, and the cleanliness of the lubricating oil and air. In the process of use, for a long time unused engine, must be started before the floating bearing system to inject a considerable amount of clean oil, to prevent the bearings in the boundary friction state operation. Long downtime, especially in winter cold start vehicles must be warmed up the engine to ensure the lubrication of the supercharger, to extend its life.
