Everything has its own lifespan, and the use time of diesel generator sets depends on the usual use process. The service life of a diesel generator set is affected by many factors. Environmental factors such as temperature, height, and humidity will have an impact on the operation of diesel generator sets.

For generators, the ambient temperature should be the inlet air temperature of the generator. Since the generator is working with the diesel engine, the diesel engine heating will cause the temperature in the entire space to exceed 40. It is very important that the ambient temperature of the generator should not exceed 40 during actual operation.

If it is below 40, the power of the generator can be higher than the rated power. When the ambient temperature exceeds 40, the higher the temperature, the lower the power of the generator.

There are also corrosive gases in the air that contain other gases of chemical nature, such as sulfur dioxide, carbon dioxide, etc.; (On the seaside) there is salt water (fog), which is easy to oxidize the surface of the diesel generator set; dust or sandstorms; Rainwater;

Therefore, we must fully consider the impact of various complex climates on diesel generator sets to ensure the normal operation of generators.

10 years.

The life of the diesel generator set depends on the brand, frequency, use environment and maintenance of the diesel generator set, the general warranty period of the diesel generator set is one year or 1000 hours (whichever comes first), if the normal use and good maintenance, the Dingbo power diesel generator set is not overhauled within 1000 hours.

In order to prolong the service life of diesel generator sets, the maintenance of air filters, oil filters and diesel filters should be strengthened to give full play to their functions.

Precautions for the use of diesel generators.

Smoking, sparking or other ignition in the vicinity of batteries and fuels is not permitted, as volatile gases from fuels and hydrogen from battery charging can be caused by sparks or open flames**.

The machine room should be equipped with BC and ABC fire extinguishers, and the operation and maintenance personnel should know how to use them.

Do not attempt to turn on the machine when the fan guard or other safety cover is removed; Do not attempt to reach under or near these protectors for service while the device is turned on.

Unless otherwise stipulated by the competent financial and tax authorities, the minimum period for calculating depreciation of fixed assets is as follows:

1) 20 years for houses and buildings;

ii) 10 years for aircraft, trains, ships, machines, machinery and other production equipment;

3) 5 years for appliances, tools, furniture, etc. related to production and business activities;

4) 4 years for means of transport other than airplanes, trains, and ships; (5) Electronic equipment, for 3 years.

Machines, machinery and other production equipment, including all kinds of machines, machinery, units, production lines and their supporting equipment, all kinds of power, transportation, transmission equipment, etc.; Electronic equipment refers to equipment composed of electronic components such as integrated circuits, transistors, and electron tubes, and the application of electronic technology (including software) to play a role, including electronic computers and robots, numerical control or program-controlled systems controlled by electronic computers. According to the provisions of the above-mentioned documents, the enterprise can judge the depreciation period of the asset in combination with the actual situation of the enterprise.

This is a relevant document, but it still depends on the economic benefits provided by the assets, and the depreciation is calculated only after considering the actual situation of your enterprise.

Generally, the service life of diesel generators is more than 20 years. But it depends on the maintenance. Regular maintenance and maintenance of the unit, if the unit is operated correctly, the life of the unit will be longer.

If the unit is not maintained, and the operation and use of the unit is incorrect, the service life of the unit will be shortened.

Therefore, it is very important for users to maintain the unit correctly when using diesel generators, which will prolong the service life of the unit.

It depends on your machine, and it's different for everyone.

Depending on how long it has been running, there will be instructions in the instruction manual of the general diesel power generation unit. You can take a look.

1. The service life of general diesel generators is more than 20 years. But it depends on the maintenance. Regularly maintain and maintain the machine Jianmengkai group, and if the unit is operated correctly, the life of the unit will be longer.

2. If the unit is not maintained, and the method of operating and using the unit is incorrect, the service life of the unit will be shortened.

3. Therefore, it is very important for users to maintain the unit correctly when using the diesel generator, which will prolong the service life of the machine car.

How to extend the service life of 200kw diesel generator set:

The correct use of diesel generator sets and the maintenance of diesel generator sets can prolong the life of diesel generator sets and increase the service time of generator sets.

Run-in: This is the basis for extending the service life of the engine, whether it is a new engine or an overhauled Qilu engine, it must be run-in according to the regulations before it can be put into normal operation.

Oil purification, water purification, gas purification and body purification: if diesel and gasoline are not pure, it will wear out the precision fitting body, increase the matching gap, cause oil leakage, oil dripping, reduce the oil supply pressure, increase the clearance, and even cause serious failures such as oil circuit blockage, shaft holding, and tile burning; If there is a lot of dust in the air, it will accelerate the wear of cylinder liners, pistons and piston rings; If the cooling water is not pure, the cooling system will be blocked due to scale, which will hinder the heat dissipation of the engine, the lubrication conditions will deteriorate, and the body will be seriously worn; If the appearance of the body is not clean, the surface will be corroded and the service life will be shortened.

Enough oil, enough water, enough air: if the high stool is insufficient or interrupted, the engine will be poorly lubricated, the body will be seriously worn and even burned; If the cooling water is insufficient, the temperature will be too high, the power will decrease, the wear will be aggravated, and the service life will be shortened; If the air is not timely or interrupted, there will be difficulties in starting, poor combustion, power drop, and the engine can not run normally.

Check the fastening parts frequently: because the diesel engine and gasoline engine are affected by vibration, impact and uneven load during use, the bolts and nuts are easy to loosen. The adjustment bolts of each part should be checked to avoid accidents that damage the body due to loosening.

The valve clearance, valve phase, fuel supply advance angle, fuel injection pressure and ignition timing of diesel or gasoline engine should be checked and adjusted in time to ensure that the engine is in good condition, so as to save fuel and prolong service life. Correct use of the engine: Before driving, lubrication parts such as shafts and pads should be lubricated.

After starting, it should wait until the water temperature is above 40 before putting into operation. It is strictly forbidden to work at high speed or overload for a long time. Before stopping, the load should be unloaded and the speed should be reduced.

After parking in winter, when the water temperature drops to 50, the cooling water should be drained (except for engines that have been filled with antifreeze). Usually do a good job of engine maintenance, so that the machine is always in good condition. It is necessary to observe and inspect frequently, find faults, and eliminate them in time. Rough rolling.

The actual operation of the diesel generator set will be affected by the environment, and the altitude and other factors such as the temperature and heat, and the size of the air pressure will interfere with the operation of the unit. What we will introduce to you is the influence of ambient temperature on the power of the generator set.

According to the international technical requirements, the ambient temperature of the generator is generally defined as 40 degrees Celsius, and all designs and powers are based on this ambient temperature.

In fact, for generators, the ambient temperature should be the inlet air temperature of the generator. Since the generator works with the diesel engine, the heating of the diesel engine will cause the temperature in the entire space to exceed 40 degrees Celsius.

It is very important that the ambient temperature of the generator should not exceed 40 degrees Celsius during actual operation. If the actual ambient temperature exceeds 40 degrees Celsius, then the generator should be operated at reduced power.

For ambient temperatures, if it is below 40 degrees Celsius, the power of the generator can be higher than the rated power.

When the ambient temperature exceeds 40 degrees Celsius, the power correction factor of the generator:

Ambient temperature (degrees Celsius) factor.
