Filter knowledge

In daily operation, many users are familiar with the construction of the filter.
Often causes the diesel filter to be the same,
Causes the three precision parts of the generator, especially the fuel system, to wear rapidly, causing undue loss

At present, many low-cost diesel generators are simple in structure, small in size, small in quality, and good in filtering effect.
And a low-cost paper diesel filter.
The paper filter is mainly composed of an aluminum filter, a steel plate stamped outer casing, and a paper filter.
The oil inlet of the filter cover is connected to the oil pump.
The oil outlet is connected to the fuel injection pump.
The oil return pipe joint is connected to the injector oil pipe,
The cover is also equipped with a venting screw plug.
Inside the paper filter assembly is a drum with many small holes.
a special filter paper that is folded on the outside,
Both ends are glued and sealed with a cover plate.
After the diesel enters the filter,
Through the filter paper,
Collected in the filter drum,
Then through the oil outlet to the fuel injection pump.
The impurities and moisture accumulated in the bottom of the casing are discharged by the oil drain plug at the lower portion of the casing.

Several problems that are easily overlooked during maintenance:

1: Some users lose the upper and lower sealing rubber gaskets and oil cover of the filter element when maintaining the diesel filter, so that the diesel oil is not filtered through the filter core, and the gap between the filter element and the filter cover flows into the filter element without resistance. The cavity causes the diesel filter to lose its filtration and purification effect.

2: Some users reverse the position of the diesel filter tray and spring, or even throw them away, so that the inlet and outlet oil holes on the diesel filter cover are open, and the diesel oil is not filtered and directly enters the fuel injection pump.

3: When someone was cleaning the diesel generator set, after removing the filter, it was found that the inside and the filter element were particularly clean and free of impurities and moisture, which means that the diesel used was very clean. As everyone knows, this is an illusion, because the filter paper of the filter element is loose and the micropores are too large. At this time, the filter paper has not been filtered at all. If during use, it is found that the three precision parts of the diesel fuel system, especially the damper pair, are seriously worn, it may be caused by inferior filter elements.

From the above, you can get a conclusion.
Everyone needs to be part of the diesel generator set,
In particular, the three-filter part of the generator set should be given great attention.
Everyone should replace or clean the filter under the normal maintenance requirements of the generator set.
