Where do diesel generators need maintenance?

Diesel generator sets are usually bought for backup, so they have been waiting for use in standby mode, but they are rarely used. In the normal state, generators are in a standby state, lacking detection, maintenance, etc., but generators are necessary. Indispensable standby power supply, if it is discovered in an emergency that the generator can not be used, it is not very crazy? The following describes the solution, in fact, can maintain the performance of the generator maintenance through regular maintenance methods to achieve Purpose, but maintenance requires an understanding of the following areas. 

The diesel engine generally includes the body, the crank connecting rod mechanism, the gas distribution mechanism, the fuel system, the lubrication system, the cooling system, and the electrical system. 

Body: It is the skeleton of a diesel engine. It is used to support and install other components, including cylinder block, cylinder liner, cylinder head, cylinder pad, oil pan, flywheel housing, timing gear housing, front and rear feet. 

Fuel supply system: According to the needs of diesel engines, diesel fuel is fed to the combustion chamber in a regular and quantitative manner. Including diesel tanks, oil pipelines, diesel filters, fuel injection pumps, fuel injectors, etc. 

Lubrication system: Lubricating oil is supplied to each moving friction pair, including oil pump, oil filter, pressure regulating valve, pipeline, meter, oil cooler, and so on.

Crank and connecting rod mechanism: It is the main moving part of a diesel engine. It can convert the energy generated by fuel combustion into pistons, piston pins, connecting rods, crankshafts, and flywheels and transfer them into mechanical energy. Including the crankshaft, connecting rod, piston, piston pin, piston pin clamping spring, piston pin bushing, piston ring, main bearing tile, connecting rod, thrust bearing, crankshaft front and rear oil seal, flywheel, shock absorber, and so on. 

Gas distribution mechanism: It is time to open and close the intake and exhaust valves. Including timing gears, camshafts, seats, jacks, rocker arms, valves, valve springs, valve seats, valve guides, valve lock blocks, intake and exhaust pipes, air filters, boosters, and more.
