Why regular maintenance and maintenance of diesel generator
09-08-2015 17:07:03 Click：4540
Diesel generator unit after power failure emergency standby power supply provider. Most of the time unit in standby state, once the blackout, unit "anxious to start, emergency power" or standby unit will lose its meaning and how to achieve the goal of? Practice has proved that: strengthen the daily maintenance is the most economical and effective method, because units long, is static, the unit itself all materials will occur complex chemical and physical changes, and the oil, cooling water, diesel oil, air, thus the unit "stop bad".
1, unit starting battery fault
Maintain the battery for a long time no one, after evaporation of electrolyte water to replenish, no allocation of starting battery charger, battery long time natural discharge after the power is reduced, or using the charger need artificial regular charging of the float switch, due to the negligence of switching operation resulting in the battery power is not up to the requirements. To solve this problem in addition to the configuration of high quality charger and the necessary inspection and maintenance is must.
2, water into the diesel engine
Due to the air moisture in the temperature change of condensation, form bead hanging attached on the inner wall of the oil tank, diesel inflows, resulting in diesel fuel moisture content exceeds, such diesel oil into the engine high pressure oil pump, corrosion precision couplings -- plunger, serious damage to the unit, scheduled maintenance and can effectively avoid.
3, oil retention period (two years)
Engine is a mechanical lubrication and oil have the retention period and stored for a long time, the physical and chemical properties of the oil will change, deterioration of lubrication condition caused by the unit work, easy to cause damage to plant parts, so lubrication oil to regular replacement.
The replacement cycle 4, filter (filter, filter, air filter, water filter)
Cannot filter, filter of diesel oil or water filter to prevent impurities from entering the machine body, and in the diesel oil and impurities is inevitable, so the unit operation process, filter plays an important role, but at the same time the oil or impurities are deposited on the screen wall and the filter capacity decreased, deposition, oil will not flow, so that the oil machine with load operation will be because of the oil supply shock (such as fan hypoxia), so the normal power generation units in use process, we suggest: first, common machine group every 500 hours replacement filter; the second, standby unit every two years to replace the filter.
5, cooling system
Water pump, water tank and pipeline for a long time without cleaning, make water circulation, cooling effect is reduced, water pipe joint is good, water tank, a water channel whether there is leakage, if the cooling system is faulty, consequences: first, cooling effect is bad and the unit internal water temperature is too high and stop, Wilson unit is the most common; second, water leakage of the water tank and the water tank water level decline, units will also not normal (to prevent in the generator is used in winter, frozen pipes, we recommend the best in the cooling system installed water heaters).
6, lubrication system, sealing parts
Due to the lubricating oil or grease in the chemical properties and mechanical wear of iron, which not only reduces the its lubrication effect, also accelerated the damaged parts, also due to the lubricating oil on the rubber sealing ring with a certain degree of corrosion, and seal itself at any time and aging so that the sealing effect is reduced.
7, fuel, gas distribution system
The engine power output is the main fuel in cylinder combustion acting and fuel is through the injector nozzle, which makes the combustion of the coke deposited on nozzle, with the amount of deposited increases the amount of fuel injection nozzle will be affected, resulting in fuel injector ignition advance angle of the time allowed, the motivation of each cylinder fuel injection quantity is not uniform, working state is not stable, so regular cleaning of the fuel system, filter element replacement oil flow, tone of the gas distribution system is the homogeneous ignition.
8, the control unit of the unit
Oil machine control unit is also an important part of the unit maintenance and maintenance, the unit use is too long, the line connection loose, AVR module work is normal.
