What is the wrong way to start the generator set?

If there is no cooling water after starting, the temperature of the cylinder assembly, cylinder head and cylinder block will rise rapidly. At this time, adding cooling water can cause important components such as hot cylinder liners and cylinder heads to burst or deform suddenly. However, if boiling water at about 100 ° C is suddenly added to the cold body before starting, cracks may also appear in the cylinder head, cylinder block and cylinder liner. Suggestion: Wait until the water temperature drops to 60 ℃ and 70 ℃ before adding.

Misunderstanding 2: Start on the accelerator

Do not use the oil filler port when the generator is started. Reminder: The correct way is to let the throttle idle. But in order to make diesel generators start quickly, before or during the start of the generator set. Here, I will tell you the dangers of this method: 1. Spent fuel and excessive diesel will flush the cylinder wall, deteriorating the lubrication between pistons, piston rings and cylinder liners, exacerbating wear; excess oil flowing into the oil pan will dilute the oil and weaken the lubrication effect; excessive diesel in the cylinder will not Will completely burn and form carbon deposits; after the diesel engine starts with a large throttle, the speed may rise rapidly, causing great damage to moving parts (increasing wear or causing failures such as cylinders).

Error 3. Forced refrigerated trailer to start

In the case of a cold car, the viscosity of the oil is large, which forces the trailer to start. This will exacerbate the wear between the moving parts of the diesel engine, which is not conducive to the extension of the service life of the diesel engine.

Four errors, the intake pipe is on ignition

If the intake pipe of the diesel generator is ignited, the ashes and hard debris generated by the combustion of materials will be sucked into the cylinder, which will easily cause the intake and exhaust valves to close improperly and damage the cylinder.

Long-term use of glow plug or flame preheater

The heater of the electric plug or flame preheater is a heating wire, which consumes a lot of power and generates heat. Long-term use will cause a large amount of battery discharge and damage in a short time, and it may also burn the heating wire.

Recommended: The continuous use time of the plug should not exceed 1 min, and the continuous use time of the flame preheater should be controlled within 30 s.

Error six, the oil is added directly to the cartridge

Adding engine oil to the cylinder can increase the temperature and pressure of the seal, which is beneficial to the cold start of the generator. However, the engine oil cannot be completely burned, it is easy to generate carbon deposits, reduce the elasticity of the piston ring, and reduce the sealing performance of the cylinder. It also accelerates the wear of cylinder liners, resulting in reduced generator power.

Error 7.Inject gasoline directly into the intake pipe

The ignition point of gasoline is lower than the ignition point of diesel, and the diesel burns in front. The gasoline is poured directly into the intake pipe, making the diesel generator rough and causing a strong knock on the cylinder. When the diesel engine is severe, the diesel engine can be reversed.
