1, The unit starts battery failure

The battery is unmaintained for a long time, and the electrolyte cannot be replenished in time after evaporation. The battery charger is not configured. The battery is discharged after a long period of natural discharge, or the charger used needs to be manually charged and floated. Due to the failure to perform the switching operation, the battery power is not required. To solve this problem, in addition to configuring a high-quality charger, necessary inspection and maintenance is necessary.


2. Water enters the diesel engine

As the water vapor in the air condenses in the temperature change, the water droplets are attached to the inner wall of the fuel tank and flow into the diesel oil, causing the diesel water content to exceed the standard. Such diesel oil enters the engine high-pressure oil pump and will corrode the precision coupling parts----- Plungers can seriously damage the unit, and regular maintenance is effective.


3, The retention period of the oil (two years)

The engine oil is mechanically lubricated, and the oil has a certain retention period. When stored for a long time, the physicochemical properties of the oil will change, causing the lubrication condition of the diesel generator set to deteriorate during operation, which is easy to cause damage to the unit parts. replace.


4, Three filter replacement cycle (wood filter, machine filter, air filter, water filter)

The filter is used to filter diesel oil, oil or water to prevent impurities from entering the body. In diesel, oil and impurities are inevitable, so the filter plays an important role in the operation of the unit, but At the same time, these oils or impurities are deposited on the wall of the filter to reduce the filter capacity of the filter. If the deposit is too much, the oil path will not be unblocked, so that the oil machine will be shocked when the load is running. Oxygen), so in the normal use of the generator set, we recommend: First, the common unit replaces the three filters every 500 hours; second, the standby unit replaces the three filters every two years.


5, Cooling system

The water pump, water tank and water supply pipeline have not been cleaned for a long time, so that the water circulation is not smooth, the cooling effect is reduced, the water pipe joint is good, the water tank and the water channel are leaking, etc. If the cooling system is faulty, the consequences are: first, cooling The effect is not good, so the water temperature in the unit is too high and the machine is shut down. The unit is the most common. Second, the water tank leaks and the water level in the water tank drops, and the unit will not work properly. (To prevent the water pipe from freezing when using the generator in winter, we recommend It is best to install a water heater in the cooling system).


6, Lubrication system, seals

Due to the chemical properties of the lubricating oil or oil ester and the iron filings generated after mechanical wear, these not only reduce its lubricating effect, but also accelerate the damage of the parts, and at the same time, due to the corrosion of the rubber sealing ring, the oil seal It is also aging at any time and its sealing effect is reduced.


7, Fuel, gas distribution system

The output of the engine power is mainly that the fuel is burned in the cylinder and the fuel is sprayed through the injector. This causes the deposited carbon to deposit on the injector. As the amount of deposition increases, the injector will receive a certain amount of fuel. The effect is that the ignition timing of the injector is not accurate, the fuel injection amount of each cylinder of the engine is not uniform, and the working state is not stable. Therefore, the fuel system is cleaned regularly, and the filter components are replaced with oil supply. The adjustment of the gas system makes it evenly ignited.


8, The control part of the unit

The control part of the oil machine is also an important part of the maintenance of the unit. The unit is used too long, the line joint is loose, and the AVR module works normally.
