If there is no cooling water after starting, the temperature of the cylinder assembly, cylinder head and cylinder block will rise rapidly. At this point, the addition of cooling water will lead to hot cylinder liner, cylinder head and other important parts suddenly burst or deformation. However, if boiling water of about 100℃ is suddenly added to the cold body before starting, the cylinder head, cylinder block and cylinder liner will also appear cracks. Suggestion: Wait until the water temperature drops to 60℃ and 70℃ before adding.
Error 2: Hit the gas and start
Do not use oil filling port when the generator is starting. Warning: The correct way to do this is to leave the throttle idling. But many people in order to get the diesel generator to start quickly, before or during starting the generator set. Here, I will tell you the harm of this method: 1. Spent fuel, excess diesel will wash the cylinder wall, so that the piston, piston ring and cylinder liner lubrication deterioration, aggravating wear; Excess oil flowing into the oil pan will dilute the oil and weaken the lubrication effect; Too much diesel in the cylinder will not completely burn and form carbon deposition; Diesel engine throttle start, the speed may rise rapidly, causing great damage to the moving parts (increase wear or cause cylinder failure).
Error 3. Force refrigerated trailer to start
Diesel generator set in the case of cold cars, the viscosity of oil, forcing the trailer to start, which will exacerbate the wear between the diesel engine moving parts, which is not conducive to the extension of the service life of the diesel engine.
Error 4. intake pipe at ignition start
If the intake pipe of the diesel generator is ignited and started, ash and hard debris generated by material combustion will be sucked into the cylinder, which is easy to cause lax closure of the intake and exhaust doors and damage the cylinder.
Error 5.Use electric plug or flame preheater for a long time
The heater of electric plug or flame preheater is electric heating wire, its power consumption and heat are very large. Prolonged use can cause the battery to be damaged by a large discharge in a short period of time, and may also burn the heating wire.
Suggestion: The continuous use time of electric plug should not exceed 1 min, and the continuous use time of flame preheater should be controlled within 30 s.
Error 6. oil is added directly to the cylinder
Adding oil in the cylinder can improve the temperature and pressure of the seal, which is conducive to the cold start of the generator, but the oil can not completely burn, easy to produce carbon, reduce the elasticity of the piston ring, reduce the sealing performance of the cylinder. It also speeds jacket wear and reduces generator power.
Error 7. Putting gasoline directly into the intake pipe
Gasoline ignition point is lower than diesel ignition point, diesel combustion before.Pouring gasoline directly into the intake pipe will make the diesel generator work rough and produce a strong knock on the cylinder. When the diesel engine is serious, it can make the diesel engine reverse.
