Diesel generator sets are used as emergency backup power sources after mains failure and power failure. Most of the time, the generator sets are in standby standby state. After the mains power failure, the unit needs to \"start in an emergency, supply power immediately\". It is very important to strengthen the maintenance and maintenance of the generator set on a daily basis, because the unit is in a static state for a long time, and its various materials will undergo complex chemical and physical changes with the oil, cooling water, diesel, air, etc., causing the unit to stop. \"The phenomenon.
1. Water enters the diesel engine
As the water vapor in the air condenses due to changes in temperature, it forms water droplets that hang on the inner wall of the fuel tank and flow into the diesel, causing the water content of the diesel to exceed the standard. Such diesel enters the engine's high-pressure oil pump and will rust the precision coupling-the plunger. Serious damage to the unit, regular maintenance is effective and avoidable.
2. Oil retention period (one year)
Engine oil is mechanical lubrication, and the oil also has a certain retention period, long-term storage, the physical and chemical properties of the oil will change, causing the deterioration of the lubrication condition of the unit when it is working, and it is easy to cause damage to the unit parts.
3. Failure of the unit starting battery
The battery is unmaintained for a long time, and the electrolyte cannot be replenished in time after the water evaporates. The battery charger is not equipped to start the battery. After the battery is discharged for a long time, the power will be reduced, or the charger used needs to be manually balanced and floated , Due to negligence and failure to perform the switching operation, the battery power cannot meet the requirements. In addition to the configuration of high-quality chargers, necessary inspection and maintenance are necessary to solve this problem.
4. Cooling system
The water pump, water tank and water pipeline have not been cleaned for a long time, which makes the water circulation difficult and reduces the cooling effect. Check whether the water pipe joints are in good condition, and whether there is water leakage in the water tank and water pipe. If the cooling system fails, the consequences are as follows: first, the cooling effect is not good and the water temperature in the unit is too high and the unit shuts down; If the water level drops, the unit will not work normally (to prevent the water pipes from freezing when the generator is used in winter, it is recommended to install a water heater in the cooling system).
5. Replacement cycle of three filters (diesel filter, machine filter, air filter, water filter)
The filter element plays a role in filtering diesel, engine oil or water and air to prevent impurities from entering the body; and the oil and impurities in the diesel are also unavoidable, so the filter plays an important role in the operation of the unit. But at the same time, these oil stains or impurities are also deposited on the wall of the filter screen, resulting in a decrease in the filtering capacity of the filter. If the deposit is too much, the oil circuit will not be unblocked. When the oil machine is running with load, it will be shocked due to the lack of oil supply. So normalGenerator setDuring use, we suggest: First, every 500 Replace the three filters every hour; second, the standby unit replaces the three filters every two years.
