2. Repair and maintain the battery every 50 hours.
3. The maintenance cycle of the belt is once every 100 hours.
4, the radiator maintenance for every 200 hours of operation.
5, lubrication oil system every 200 hours of maintenance.
6. The maintenance of diesel filter shall be carried out once every 200 hours.Remove the diesel filter, replace it with a new one, fill it with new diesel, and put it back in.
7. The maintenance of charging generator and starting motor shall be carried out once every 600 hours.
8. The maintenance of the control panel of the generator set shall be carried out every six months.Remove the dust with compressed air and tighten the wiring heads. The rusty or overheated wiring heads should be handled and tightened.
One, daily inspection
In the daily inspection, it is necessary to check the external of the generator set, whether there is a phenomenon of leakage of the battery solution, and check the voltage value of the battery and the temperature of the water in the cylinder liner.In addition, it is necessary to check whether the heater of the cylinder liner water, the charger of the battery and the dehumidification heater are maintained in normal operation.
Need to check:
1. The unit starts the battery
Battery for a long time no maintenance, electrolyte moisture volatilizes not timely supplement, no configuration starter battery charger, the battery for a long time after natural discharge capacity is reduced, or the charger need manual on a regular basis are used by floating rearrangement of, due to gross negligence make rearrangement of the battery power can not meet the requirements, solve the problem in addition to configure high quality charger,Necessary testing and maintenance is required.
2. Water enters the diesel engine
Due to the condensation phenomenon of water vapor in the air at the temperature change, water droplets form and hang on the inner wall of the oil tank and flow into the diesel oil, resulting in excessive water content of the diesel oil. Such diesel oil into the engine high-pressure oil pump will rust the plunger of precision coupling parts and seriously damage the unit. Regular maintenance can be effectively avoided.
3, lubrication system, seals
Due to the chemical characteristics of the lubricating oil and the iron filings produced after mechanical wear, these not only reduce its lubrication effect, but also accelerate the damage of parts. At the same time, because the lubricating oil has a certain corrosion effect on the rubber sealing ring, and the oil seal itself is also aging at any time, so that the sealing effect decreases.
4. Fuel and gas distribution system
Engine power output is mainly the fuel in the combustion in cylinder power and fuel is through nozzle jet, this makes the combustion of carbon deposit on the nozzle, with the increase of the deposition quantity of nozzle spray oil it will have certain influence, cause the nozzle ignition advance Angle of time, each cylinder engine fuel injection quantity is not uniform, working condition is not stable,Therefore, the regular cleaning of the fuel system, the replacement of the filter parts, the smooth oil supply, and the alignment of the gas distribution system make the ignition uniform.
5. Control part of the unit
The control part of the machine is also an important part of the maintenance of the unit. The unit is used too long, the line joint is loose, and whether the AVR module works normally.
Second, monthly inspection
The monthly inspection needs to switch between the generator set and the mains power, and the start-up of the generator set and the on-load experiment need to carry out in-depth inspection.
Three, quarterly inspection
During the quarterly inspection, the generator set needs to be at more than 70% load before it can operate for 1 hour to burn up the mixture of diesel and oil in the cylinder.
Four, yearly check
Annual inspection is an important part of the maintenance cycle of standby diesel generator sets, which not only needs quarterly and monthly inspection, but also needs to carry out more maintenance projects.
The service life and power of diesel generator sets are not only important for seasonal maintenance, but also for daily maintenance of diesel generator sets.Starting from the details, we can make better use of diesel generator sets.
Maintenance needs to be replaced:
1, oil
The engine oil is mechanical lubrication, and the oil also has a certain retention period. When stored for a long time, the physical and chemical properties of the oil will change, resulting in the deterioration of the lubrication condition at work of the unit, which is easy to cause the damage of the unit parts. Therefore, it needs to be replaced once a year.
2, filter
Filter is refers to the wood filter, filter, air filter, water filter, is, the role of diesel oil, engine oil or water filtration, prevent impurities into the body and impurities in diesel oil, is also the inevitable existence, so in the process of unit operation, the filter has played an important role, but at the same time, the oil pollution or impurities will be deposited in the screen wall and make the filter ability, deposit too much,The oil circuit will not be unblocked, so the oil machine will be unable to supply shock due to oil (like people lack of oxygen) when carrying, so the normal generator set in the use of the process, we suggest: common unit to replace the filter every 500 hours;The standby unit replaces the filter every year.
3. Antifreeze
Antifreeze is an indispensable heat dissipation medium for the normal operation of diesel generator sets. One is to give the unit water tank antifreeze, which will not freeze and expand in winter and burst;The second is to cool the engine. When the engine is running, the effect of using antifreeze as circulating cooling liquid is obvious.The long-term use of antifreeze is easy to contact with air and oxidation, affecting the antifreeze performance, so it needs to be replaced once a year.
