How to maintain a diesel filter? How to filter diesel to be clean?

Air filter is an important part of the diesel engine air supply system, it can make the air into the intake pipe be purified, if the air filter maintenance is not timely or incorrect, it will make the cylinder liner, piston ring, intake and exhaust valves and other parts seriously wear early, so that the engine power decreases, and even seriously shortens the service life of the engine. The specific maintenance method is: when the dust of the dust collection cup exceeds 1 3, it must be removed, and the dust in the pipeline should be removed in time.

When installing the dust cup, the gasket should be installed, and its tightness should be paid attention to. Regularly check and change the oil in the oil pan of the oil-bath air filter. The oil level should not exceed the ring groove in the oil pan, so as to prevent the oil from being sucked into the cylinder, causing carbon deposits or causing speeding.

When the oil thickens and the fluidity is poor, it should be cleaned and replaced in time, and the filtered waste engine oil should be diluted by adding 1 3 diesel fuel to the engine oil in winter. Clean the metal filter screen in time according to the operating conditions, and then soak the oil after the cleaning oil drips dry during installation, and then assemble it after the excess oil is exhausted. Dry paper filters can not be cleaned with diesel, and can be cleaned by gently pat the ends of the filter to shake off the dust during maintenance, and then sweep it with a soft brush or blow it from the reverse side with compressed air.

It is best not to clean, and then see or change the kilometers directly, because cleaning you can not ensure that there is no debris entering, and replace the diesel filter regularly according to the quality of the diesel oil added.

What car are you? The diesel filter of the EFI engine is very critical, and the 2-30,000 highway replacement, and the oil-water separator should be released frequently. I haven't heard that the diesel filter has a clean, mine.

Generally, it is cleaned in half a month.

1. For solid impurities, such as sand or ants, filtration methods can be used. Find clean filter materials (filter cotton, filter gauze, etc., if you can't buy these special filter cloths, use clean towels, fabrics, etc.), find a funnel, and then fold the filter material into a funnel shape and put it into the funnel, and pour the oil mixed with impurities into the funnel. If the impurities are not completely removed after filtration, change the filter material and continue to filter, and repeat many times to remove the impurities.

2. Water mixed into the oil can easily cause the grease to smell, so after the oil enters the water, the water should be removed. For a small amount of water, it can be removed by heating and evaporating the water, and the oil is poured into a hot pan, preferably with a pot that can control the temperature, it is recommended to control the temperature of the pot at 100 degrees Celsius.

Left and right, stir while heating, the oil with moisture will bubble in the hot pan, and heat until the oil does not bubble, and the water can be completely removed.

3. For the case of mixing more water, desiccant can be used.

Water absorption, after the desiccant absorbs water, and then the desiccant is removed by filtration, and may also participate in trace moisture, and then removed by heating. Generally, quicklime granules desiccant can be used. The desiccant dewatering process is like this: put quicklime powder.

The desiccant is sprinkled into the mixed oil, stirred while slowly sprinkled, until the quicklime particles are no longer dissolved, fully stirred for about half an hour, and then the oil is placed in a cool and dry place to stand and precipitate for about 12 hours, and finally the upper layer of clarified oil is poured out for filtration and trace water removal.

4. For the oil mixed with water-soluble impurities such as mud and dust, if the impurities cannot be filtered out, the dust can be removed by water treatment. Pour more water into the oil (the amount of water added is more than double the oil), and then use a spoon and other tools to stir constantly, it is recommended to stir for about half an hour, the specific time can be decided, and then put the oil in a cool and dry place to stand for about 12 hours, and then pour out the clarified part of the upper layer, and finally remove the water.

The method of cleaning the oil filter element of a diesel engine is as follows:

1. Use the tool to remove the buckle.

2. Put the buckle away and gently remove the engine panel.

3. The upper right corner of the engine is the air filter, which is hidden in the box. Pull the three active buckles of the air filter outward, and the box will come loose.

4. After opening, the white card is the air filter. With a high-pressure water gun.

Or a hair dryer.

Or some other way to clean it up.

5. The plane is on the top, the convex one is placed below, and after the movable buckle is all in place, you can wipe the engine compartment parts with a wet towel to wipe the dust clean.

6. The buckles are returned to their positions one by one, and they can be pressed down.

Cleaning method of diesel engine filter:1. The air filter should be cleaned every 50-100 hours before the previous training, and the surface dust can be brushed off with a soft brush.

2.For oil bath air filters, clean the filter element with clean diesel every 100-200 hours. 3. Oil filter, the method is to use oil, kerosene and diesel fuel mixed as cleaning oil for cleaning.

Cleaning method of diesel engine filter:1. The air filter should be cleaned every 50-100 hours, and the surface dust can be brushed off with a soft brush.

If the working time is more than 500 hours or it has been damaged, it should be replaced in time. When installing, the sealing gasket and rubber connecting pipe should not be missed, reversed or misplaced, and the tightness of the embedded parts should be ensured.

2.For oil bath air filters, wash the filter with clean diesel fuel every 100-200 hours and change the oil in it. If the filter element is broken, it needs to be replaced immediately, and pay attention to refueling according to the regulations when using.

Engine oil is an important grease for lubricating diesel engines, which plays an irreplaceable role in ensuring the stable operation of diesel engines.

3. Oil filter, the method is to use oil, kerosene and diesel fuel mixed as cleaning oil for cleaning. During the use of the diesel engine, if the oil filter is not maintained in time, the filter element is blocked, the oil and pressure rise, the safety valve is opened, and the lubricating oil flows directly into the main oil circuit, which will aggravate the wear of the lubrication surface and affect the service life of the diesel engine. The oil cleaning filter should be cleaned every 180-200 hours.

If damaged, it should be replaced immediately to prevent impurities from entering the lubricated surface. Clean the parts. The diesel fuel used should meet the seasonal requirements and should be precipitated and purified for 48 hours.
