Reasons for periodic maintenance of MTU diesel generator sets

Generating sets are widely used in industrial and agricultural production, national defense, science and technology and daily life. In recent years, with the progress of technology, as a high-quality choice for family emergency power supply and outdoor travel power supply, lightweight portable small generator sets have also begun to enter the daily life of residents. However, the generator set should be regularly maintained. What is the cause of that?

Practice has proved that strengthening daily maintenance is the most economical and effective method, because the unit chief is static, the unit itself of various materials and oil, cooling water, diesel, air and other complex chemical and physical changes, so as to "stop broken" the unit.

1. Starter battery failure battery for a long time no maintenance, electrolyte after moisture volatilizes not promptly added, without starting battery charger, battery after long time 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, To solve this problem in addition to the configuration of high quality charger, the necessary inspection and maintenance is necessary.

2. Water into diesel engine because of the moisture in the air condensing phenomenon in the change in temperature, forming water attached to the tank wall, into the diesel oil, diesel fuel moisture content exceeds bid, the diesel oil into the engine high pressure oil pump, will rust precision coupled parts -- -- -- -- -- plunger, serious damage units, regular maintenance that can be avoided effectively.

3. Oil retention period (two years) the engine oil is mechanical lubrication, and the oil also has a certain retention period, long time storage, the physical and chemical properties of the oil will change, resulting in deterioration of the lubrication condition of the unit, easy to cause damage to the unit parts, so the lubricating oil should be replaced regularly.

4. Three filter replacement cycle (wood filter, machine filter, air filter, water filter) filter is to play a role in the diesel, oil or water filtration, to prevent impurities into the body, and in the diesel oil, impurities are inevitable, so in the process of unit operation, the filter plays an important role, But at the same time these oil or impurities will be deposited on the screen wall, so that the filter filtration capacity is reduced, too much deposition, the oil will not be smooth, so the oil machine will be transported with oil supply shock (like hypoxia), so the normal generator set in the process of use, we suggest:

First, the common unit every 500 hours to replace the filter;

Second, the standby unit every two years to replace the filter;

5. The cooling system water pump, water tank and water pipe for a long time not cleaned, so that the water circulation is not smooth, the cooling effect is decreased, whether the water pipe joint is good, water tank, water channel is leaking, etc., if the cooling system is faulty, the consequences are: first, the cooling effect is not good and the water temperature in the unit is too high and stop; Second, the water tank leakage and make the water level in the water tank drop, the unit will not work properly (in order to prevent the use of generators in winter, water pipe freezing, we recommend that the best installation of water heaters in the cooling system).

6. Lubrication system, oil seal due to oil or ester chemical properties and mechanical wear of iron filings, which not only reduce the lubrication effect, also accelerated the damage of the parts, at the same time due to the lubricating oil has certain corrosion effect to the rubber sealing ring, oil seal itself also at any time and aging decreased its sealing effect.

7. Fuel oil, the output of the engine power distribution system is mainly the fuel in the combustion in cylinder power and fuel is through nozzle jet, this makes after combustion of coke deposit on the nozzle, with the increase of the deposition quantity of nozzle certain influence on the fuel injection quantity, 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 adjustment of the gas distribution system make the ignition uniform.

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 for too long, the line joint is loose, and the AVR module works normally.

Jiangsu Meiao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
