Routine maintenance: on the basis of routine maintenance, every six months or a year to do maintenance can be
1, the generator set of water, electricity, oil, gas and other Carry out a comprehensive inspection to confirm whether the unit is normal;
2, no-load test 5-10 minutes, so that the unit is fully lubricated; by listening, watching, smelling and other methods to determine the use of the unit condition;
3, replacement of air filters, diesel fuel filters, oil, oil filters, water filters, oil-water separator cartridges and other consumables;
4, replacement of the radiator tank coolant, water tank treasure;
5, add the battery battery liquid or distilled water;
6, maintenance is completed, the unit for another inspection, and cleaning and cleaning;
7, no-load test machine 5-10 minutes, the unit's performance parameters to record, put forward rationalization proposals, customer acceptance.
Applicable to long-term operation of the generator set maintenance program: (such as construction sites, frequent power outages in factories, transformer load is not enough, project testing, can not pull the utility, etc., the need for frequent or continuous operation of the generator set)
Level I Technical Maintenance: (50-80 hours) in the daily maintenance of the contents of the increase
1, clean air filters, necessary Replace when necessary;
2, replace the diesel filter, air filter, water filter;

1, check and adjust the injection lifting angle;
2, clean the fuel tank;
3, clean the oil sump;
4, check the atomization of the injector nozzle
Why generator sets for maintenance?
Diesel generator sets are for utility failures and power outages after the emergency standby power provider, the vast majority of the time the unit is on standby standby state, once the power outage, the unit is required to "start in a hurry, in a hurry to power supply," otherwise the standby unit will be meaningless, how can we achieve this purpose? Practice has proved: to strengthen the daily maintenance is the most cost-effective way, because the unit is long in static, the unit itself a variety of materials and oil, cooling water, diesel fuel, air, etc., complex chemical and physical changes, so that the unit "stop bad".
1, failure of starting battery of the set
The battery is not maintained for a long time, the electrolyte is not replenished in a timely manner after the water is volatilized, there is no charger for the starting battery, and the battery power is reduced after a long time of natural discharging, or the charger used is required to manually carry out the inverting of equalizing and floating charging on a regular basis, and due to the negligence of not carrying out the inverting operation, the power level of the battery is not up to the requirement. In addition to the configuration of high-quality chargers, the necessary testing and maintenance is necessary.
2, water into the diesel engine
The air condensation phenomenon occurs due to changes in the temperature of the water, formed into a water droplet hanging attached to the inner wall of the tank, into the diesel, resulting in the diesel water content of the diesel exceeds the standard, such diesel fuel into the engine high-pressure oil pumps, will be rusted Precision Coupling Parts ----- plunger, serious damage to the unit, regular maintenance that is effective can be avoided.
3, oil retention period (two years)
Engine oil is a mechanical lubrication, and the oil has a certain retention period, long time storage, the physical and chemical properties of the oil will change, resulting in the deterioration of lubrication when the unit is working, easily triggered by the unit parts damage, so the lubricant should be replaced regularly.
4, three filter replacement cycle (diesel filter, filter, air filter, water filter)
Filter is to play a role in diesel fuel, oil or water filtration, in order to prevent impurities into the body, and in the diesel fuel oil, impurities are unavoidable, so in the process of the unit's operation, the filter plays an important role, but at the same time, these oil or impurities will be deposited in the wall of the filter to make the Filter filtration capacity is reduced, too much deposition, the oil circuit will not be able to smooth, so the oil machine running with load will be unable to supply oil and shock (as people lack of oxygen), so the normal generator set in the use of the process, we recommend that: First, commonly used units every 500 hours to replace the three filters; Second, standby units every two years to replace the three filters;
5, cooling system
Water pumps, tanks and water pipelines have not been cleaned for a long time. Water pumps, water tanks and water pipelines have not been cleaned for a long time, so that the water circulation is not smooth, the cooling effect is reduced, whether the water pipe joints are good, water tanks, watercourses, water leakage, etc., if the cooling system has a fault, leading to the consequences of: First, the cooling effect is not good and make the set of water temperature is too high and shut down, wilson set is the most common; Second, the water tank leakage and make the water level in the water tank drops, the unit will not work properly (in order to prevent the use of generators in winter, the water pipe freezing, the unit will not work properly). using the generator, the water pipe freezes, we suggest that it is best to install a water heater in the cooling system).
6, lubrication system, seals
Because of the chemical properties of lubricating oil or oil ester and mechanical wear and tear of iron filings, which not only reduces its lubricating effect, but also accelerates the damage to the parts, and at the same time, because of the lubricating oil on the rubber seals have a certain degree of corrosive effect, in addition to the oil seals themselves at any time and the aging of the seal to make its sealing effect decreased.
7, fuel, gas distribution system
Engine power output is mainly fuel combustion in the cylinder work and fuel is sprayed through the injector nozzle, which makes the combustion of carbon deposits in the injector nozzle, with the increase in the amount of deposition of the injector nozzle injection will be affected by a certain amount of injector nozzle ignition advance angle is not allowed to lead to the time, the engine cylinder injection is not uniform, the working condition is not stable. Therefore, regular cleaning of the fuel system, the replacement of filtering parts of the fuel supply is smooth, the gas distribution system correction to make its ignition uniform.
8, the control part of the set
The control part of the oil machine is also an important part of the maintenance of the set, if the set is used for too long, the line connector is loose, and whether the AVR module is working normally or not.
