What are the hazards of unmaintained Shangchai diesel generators? Let me explain it for everyone:
1. Cooling system
If the cooling system is faulty, it will cause two results. 1) The cooling effect is not good and the water temperature in the unit is too high and the unit stops; 2) the water tank leaks and the water level in the water tank drops, and the unit cannot operate normally.
2. Fuel/air distribution system
The increase in the amount of coke deposits will affect the fuel injection volume of the fuel injector to a certain extent, resulting in insufficient fuel injection, and the fuel injection volume of each cylinder of the engine is not uniform, and the operating conditions are also unstable.
3. battery
If the battery is not maintained for a long time, the electrolyte moisture will not be compensated in time after evaporation, and the battery charger is not equipped to start the battery, and the battery power will be reduced after a long-term natural discharge.
4. engine oil
Engine oil has a certain persistence period, that is to say, if it is not used for a long time, the physical and chemical functions of the oil will change, and the cleanliness of the unit will deteriorate during operation, which will cause damage to the unit parts.
5. fuel tank
Water entering the air of the diesel generator set will condense when the temperature changes, forming water droplets and hanging on the inner wall of the fuel tank. When the water droplets flow into the diesel, the water content of the diesel will exceed the standard. When such diesel enters After the engine’s high-pressure oil pump, the precision coupling parts will be corroded. If it is serious, the unit will be damaged.
6. three filters
During the operation of the diesel generator set, oil stains or impurities will deposit on the wall of the filter screen, and the filtering function of the filter will be reduced if the filter is too much deposited, the oil path will not be dredged, and the equipment will be unable to supply oil when the equipment is working. malfunction.
7. lubrication system, seals
Due to the chemical properties of lubricating oil or oil ester and the iron filings that occur after mechanical wear, these not only reduce its lubricating effect, but also damage other parts. At the same time, because lubricating oil has a certain corrosive effect on rubber seals, other oil seals It also deteriorates due to its aging at any time.
