Diesel generator set ten taboos

In order to make diesel genset can operate properly, Shandong huaquan power co.,ltd  Talk to you use generating set of the ten big taboo.
First, no cooling water, or add boiling water after start engine start to add cooling water, can make the hot cylinder liner, cylinder head and other important components caused by the sudden encounter cold cracking or deformation;To the cold snap in body plus 100 ℃ hot water, also can shock crack cylinder head and the body, should stay when the temperature dropped to 60 ~ 70 ℃ to join again.
Second, is not in accordance with the provisions, diesel engine oil supply should not be at start up will stress the handle into the "work" out oil supply, and should be before the launch will throttle lever on the location of the fuel supply.According to the instructions of the harm is: not waste fuel;Redundant diesel will scour the cylinder wall, make the deterioration of lubrication between the piston, piston ring and cylinder liner and aggravate the wear;Residual oil into the oil pan will be diluted oil lubrication and the effect;Incomplete combustion of diesel will be too much in the cylinder form carbon deposition.
Three, cart to start the diesel engine under the condition of the cold car engine oil sticky cart, exacerbate between each moving parts wear and tear, thus reduce the service life of the locomotive.
Four, not on schedule in used lubricating oil, fuel oil in the cold weather season, if not timely change of low viscosity lubricating oil and fuel oil, diesel engine is hard to start.
Five, with open flame roasting the oil pan and the fire started at inlet pipe to prevent fire, application soft fire, coal fire in a certain distance baking of diesel engine oil pan, slowly shake shaft oil at the same time, let the oil evenly heat, make each part have been lubrication.If a fire started on the diesel engine intake pipe, can make the material burning ash and hard sundries sucked into the cylinder, intake and exhaust door closed lax caused to speed up the cylinder wear.Six, long time using electro-thermal plug, flame preheater electro-thermal plug, flame preheater of the heating element for the heating wire, its power consumption and heat output is very big, use for a long time can damage because of rapid discharge of battery, at the same time also can burn out heating wire.Electric plug, therefore, each time not more than 1 minute continuous use, every time the flame preheater of continuous use time to control within 20 seconds.
Seven, to add oil to add oil cylinder cylinder directly, can have the effect of sealing pressurization warming, is advantageous for the diesel engine cold start, but cannot complete combustion engine oil, easy to produce carbon, lessened the flexibility of piston ring, cylinder sealing performance;In addition, will also accelerate the wear of cylinder liner, resulting in a decline in the power of the diesel engine, make it more difficult to start, so can't directly to add oil cylinder.
Eight, directly to the gasoline pumped into the intake pipe gas ignition point was lower than those of diesel, before diesel combustion.So directly to the gas inlet pipe, and can make the engine work rough and produces strong knocking phenomenon, serious when still can happen engine inversion.
Nine, long time continuous to start the diesel engine is under the condition of the low voltage, high current work, use for a long time will damage the battery.The continuous working time shall not be more than 5 seconds;Once started, should every 15 seconds to start again.
Ten, just start the high-speed diesel engine has just started, the temperature of the lubricating oil is low, the liquidity is poor, high-speed operation immediately, easy to cause the movement parts sharply due to lack of lubrication and wear, serious when still can happen tile burning shaft.
