A diesel generator is just like its literal meaning. It belongs to a kind of mechanical equipment for generating electricity. We can often see it in many mountainous areas and power outages. It can effectively provide electricity. So what is the relevant knowledge about it? What do we not know? Let's find out with Xiaobian below. The following is the introduction of "care methods for diesel generators and their brand categories".
[Daily maintenance tips for diesel generators]
Some items of diesel generator filter maintenance:
1. The baffle plate of the air filter should be not deformed or corroded. Its inclination angle should be 30 to 45 °. If it is too small, the resistance will increase, which will affect the air intake. If it is too large, the airflow will rotate and weaken. Decrease. The surface of the blades must not be painted to prevent oxidation particles from entering the cylinder. The direction of the dust outlet should be able to discharge dust particles.
2. The ventilation mesh should be cleaned during maintenance; for dust cups, the dust particles should not exceed one third of the height, otherwise it should be removed in time; the mouth of the dust cup should be tightly sealed, and the rubber seals must not be damaged or lost. .
3. The oil level of the fine filter should comply with the standard requirements. Too high will cause the oil to enter the cylinder and deposit carbon, while too low will reduce the filtering effect and make it wear faster.
4. If the metal mesh (wire) in the fine filter is used instead, the diameter of the perforations or wire can only be slightly smaller, it cannot be increased, and the filling amount must not be reduced, otherwise the filtering effect will be reduced.
5. There must be no air leakage in the air inlet pipe. Oil change and cleaning should be performed in a place without wind and dust. Blow the filter with high pressure air in a low humidity environment. The direction of the blow should be with the air entering the filter. The directions are opposite; when installing, the fold directions of adjacent filters should cross each other.
Main points of oil filter maintenance:
The oil filter must be maintained according to the specified time, and the following points must be noted: Centrifugal oil filter. Pay special attention to the installation after removing and washing the centrifugal fine filter:
① There should be no card blocking phenomenon. The inspection method is that when the rotor is reassembled, turn the rotor by hand and force it. After letting go, the rotor can freely rotate 2-3 times and then stop.
② You can also install a fine filter on the car, start the engine, and run it for a few minutes at the rated speed. When the oil temperature reaches 70 ° C, it will stop. At this time, listening to the rotor outside the housing continues to rotate, which can reach more than 1.5 minutes, that is Qualified for installation. If the above indicators are not achieved, the installation is unqualified and reassembly should be performed.
The third filter is an important protection device for diesel generators, and it is also easy to be damaged and needs maintenance. Good maintenance and maintenance can ensure the normal operation and service life of diesel generators.
[Brand of Diesel Generator]
I. Imported brand diesel generator sets
We are talking about imported diesel generators from international famous brand companies. Such as Caterpillar in the United States, Cummins, Rolls-Royce in the United Kingdom, Deutz in Germany, the rich in Sweden and so on. This writing machine has fine workmanship, stable performance and rich money, of course.
Joint venture diesel generator sets
In recent years, some Chinese companies have begun to introduce advanced diesel engine technology from abroad to produce diesel engines in joint ventures with well-known foreign engine companies. The generator set produced by this engine is a joint venture. These machines have introduced many advanced technologies.
The quality of workmanship is very good. The performance is also quite good. It is a unit that has been sold for several years. Because these units are cost effective.
Third, domestic diesel generators
In the past few years, the level of domestic diesel engines that have absorbed foreign technology has greatly improved. Many domestic diesel engines perform no less well than joint ventures.
When buying, not only the brand of the diesel engine must be considered, the brand of the motor is also very important. The parameters and performance of the regular big brand motors are very standard, and the energy conversion has reached the state. We must pay attention to domestic Weichai and Shangchai. To distinguish between fakes and fakes, fakes are so-called branch factories that use Chinese naming habits to mix fish and fish. They are called Weichai in production and Shangchai in production. The quality of these small factories is uneven and it is difficult to guarantee the quality.
