The reasons why the diesel generator cannot turn on are:
1. There is no oil in the fuel tank and the engine cannot ignite due to a blockage in the oil circuit.
2. There is moisture in the diesel fuel, which prevents the engine from starting.
3. When air enters the oil supply system and the piston of the high pressure oil pump rises, it can only compress the air, preventing the engine from igniting.
A generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by water turbine, steam turbine, diesel engine or other electric machines to convert the energy generated by water flow, air. flow, fuel combustion or atomic nuclear fission. Mechanical energy is transmitted to the generator, which is then converted into electrical energy.
The reasons why the diesel generator does not catch fire: 1. The friction surface is not lubricated in time. 2. The lubricating oil film on the cylinder wall is damaged. 3. Corroded by acidic substances.
1. The friction surface is not lubricated in time. During a cold start, the oil pump cannot immediately pump lubricating oil to each friction surface. Deterioration of initial lubrication conditions;
2. The lubricating oil film on the cylinder wall is damaged. Due to the low temperature, it is difficult for gasoline to atomize, and some of the unatomized fuel enters the cylinder in a liquid state, eliminating the oil film remaining on the cylinder wall, aggravating the lubrication conditions between the cylinder wall and the piston ring, which leads to a sharp increase in wear. This condition exists in varying degrees until the enginereaches a normal temperature. Therefore, the practice of abruptly “pressing” the accelerator after a cold start is very harmful and must be resolutely corrected.
3. Corroded by acidic substances. Before the engine reaches normal operating temperature, the sulfide produced by gasoline combustion combines with water vapor condensed on the cylinder to form acidic substances, corroding the cylinder wall and rings. piston and accelerating wear. The lower the engine operating temperature, the greater the wear.
It is difficult to preheat part of the transmission. Its normal temperature is often guaranteed by the friction between the parts and the heat generated by the brewing oil, and the temperature rises slowly. At this point, the gears and bearings are not fully lubricated, increasing their wear. At low temperatures, the engine cylinder and lThe intake pipe are filled with cold air, the starting speed is slow, the heat dissipation is large, and the gasoline cannot be completely vaporized and burned, which not only increases fuel consumption, but also reduces the power of the engine. .
