As power supply equipment, diesel generator sets are used in public utilities, education, electronic technology, engineering construction, industrial and mining enterprises, animal husbandry, communication, biogas engineering, trade and other industries.

Basic principle of diesel generator set;

In the diesel engine cylinder, the clean air filtered by the air filter is mixed with the high-pressure atomized diesel oil sprayed by the oil nozzle. Under the upward extrusion of the piston, the volume decreases and the temperature increases, reaching the ignition point of diesel oil. Diesel is ignited, the mixture burns violently, the volume expands, and the piston is pushed down. This is called work. Each cylinder does work in turn according to a certain order, and the thrust acting on the piston becomes the force to push the crankshaft to rotate through the connecting rod, thus driving the crankshaft to rotate.

Maintenance of diesel generator set;

First, daily:

1) Check the daily work report of the generator.

2) Check the generator: oil level and coolant level.

3) Check the generator for damage, leakage and belt looseness or wear every day.

Second, every week:

1) Repeat the daily inspection.

2) Check the air filter and clean or replace the air filter core.

3) Drain water or deposits from the fuel tank and fuel filter.

4) Check the water filter.

5) Check the starting battery.

6) Start the generator and check whether there is any influence.

7) Radiators at the front and rear ends of the fresh water cooler.
