What should we pay attention to when using small diesel generators?
1. After a cold start, the machine operates under load without preheating. When the diesel generator starts cold, due to the high viscosity and poor fluidity of the oil, the oil pump does not supply enough oil, and the friction surface of the machine is poorly lubricated due to lack of oil, causing rapid wear and even malfunctions such as cylinder pulling and tile burning.
2. The diesel generator works when there is insufficient engine oil. At this time, insufficient oil supply will cause insufficient oil supply to the surfaces of each friction pair, resulting in abnormal wear or burns. It is for this reason that it is necessary to ensure that there is sufficient engine oil before starting the machine and during engine operation.ur diesel to avoid cylinder pulling and tile combustion failures caused by lack of oil.
3. Emergency stop with load or stop immediately after sudden removal of the load. After the diesel engine stalls, the circulation of cooling water stops, the heat dissipation capacity decreases sharply, and the heated parts lose cooling, which can easily cause overheating of the cylinder head, cylinder liner , cylinder block and other mechanical parts, producing cracks, or causing the piston to overexpand and get stuck in the cylinder liner. Therefore, before the diesel generator stalls, the load must be discharged, the speed must be gradually reduced, and the engine must run without load for a few minutes.
4. Accelerate the diesel engine hard after a cold start. If the accelerator is pressed hard, the engine speeddiesel engine will increase sharply, which will lead to violent wear of some friction surfaces of the engine due to dry friction.
5. Operate when cooling water and engine oil temperatures are too low. During diesel engine operation, the cooling water temperature is too low and the cylinder wall temperature drops accordingly. The water vapor generated by combustion condenses into water droplets and comes into contact with the exhaust gases to generate acidic substances that stick to the engine. cylinder wall, causing corrosion and wear.
The amount of diesel a diesel generator needs to generate one kilowatt hour of electricity is related to the following two factors:
1. Fuel consumption rates of generators of different brands. have different fuel consumption rates. , fuel consumption edifferent st;
2. The size of the electric load is large, the fuel consumption will be higher if the accelerator is used. , if the load is small, the fuel consumption will be less.
The specific calculation method of generator fuel consumption is as follows:
One liter of diesel is approximately equivalent to 0.84-0.86 kg (1L=0. 8-0.85KG).
Most parameters used by generator manufacturers use G/KW.H, which means how many grams (G) of oil the generator consumes per kilowatt per hour, then the unit is converted to liters (L) This way you can know how much fuel you consume per hour.
In order for everyone to understand the approximate fuel consumption of the generator, calculate the cost of using the generator; give yourself an approximate reference value (30 kW-500 kW).
Fuel consumptiont of 30kw generator set = 6.3 kilograms (kg) = 7.8 liters (L)
The fuel consumption of 45kw generator set = 9.45 kilograms (kg)? = 11.84 liters (L)
Fuel consumption of 50 kW generator set=10.5 kilograms (kg)?=13.1 liters ?(L)
Consumption fuel consumption of 75 kW generator set=15.7 kilograms ( kg)?=19.7 liters?( L)
10Fuel consumption of 0 kW generator set = 21 kilograms (kg) = 26 .25 liters (L)
Fuel consumption of 150 kW generator set = 31.5 kilograms (kg) = 39.4 liters (L)? p>Fuel consumption of 200 kW generator set = 40 kilograms (kg)? = 50 liters (L)
Fuel consumption of 250 kW generator set = 52.5 kilograms (kg = 65.6 liters)?
Fuel consumption of the 300 kW generator = 63 kilograms (kg)? = 78.75 liters? (L) ?
Fuel consumption of 350 kW generator set = 73.5 kilograms (kg)? = 91.8 liters (L)
p>Fuel consumption of 400 kW generator set = 84.00 kilograms (kg) = 105.00 liters (L)
Consumption fuel of 450 kW generator set = 94.50 kilograms (kg = 118.00)? liters (L)
Fuel consumption of a 500 kW generator = 105.00 kilograms (kg = 131.20 liters)
