Common knowledge of construction machine filter core maintenance

Filter element is an important part of construction machinery, oil filter, fuel filter, air filter, hydraulic filter, for these construction machinery filter, do you understand their specific role and maintenance of the main points?

Small collection of engineering machinery filter elements should pay attention to the daily use of problems, as well as some maintenance knowledge!

The function of the oil filter is to filter the sludge in the engine and the impurities produced by the deterioration of the engine oil to prevent the deterioration of the engine oil, and to minimize the wear and tear of the parts during operation.

Under normal circumstances, the engine oil filter replacement cycle for the first time 50 hours of replacement, and then every 250 hours to replace.

Common problems of oil and fuel filter

1., in any special case, you need to replace the oil filter, fuel filter?

Fuel filter is to remove the iron oxide, dust and other magazines in the fuel, to prevent fuel system congestion, reduce mechanical wear and tear, and ensure the stable operation of the engine.

Under normal circumstances, the engine fuel filter replacement cycle for the first time 250 hours of replacement, then every 500 hours for replacement, should be in accordance with the different quality of fuel quality, flexible replacement time.

When the filter pressure gauge alarm or indicate the pressure is not normal, you need to check the filter is abnormal, if it has, must be changed.

When the filter surface leakage or deformation phenomenon, you need to check the filter is abnormal, if it has, must be replaced.

2. whether the filtration accuracy of the oil filter is better?

For an engine or equipment, a proper filter core should be balanced between the filtration efficiency and the ash content.

If the filter element with high filtering accuracy is used, the service life of the filter core can be shortened because of the low ash content of the filter element, thereby increasing the risk of premature plugging of the oil filter element.

3., poor quality oil, fuel filter and pure oil, fuel filter on the role of equipment, what is the difference?

Oil, fuel filter can effectively protect the pure equipment, prolong the service life of other protective equipment installed, inferior oil, fuel filter is not good, can not prolong the service life of the devices, or even worsen equipment usage.

4. what advantages can you bring to the machine by using high quality engine oil and fuel filter?

The use of high quality oil, fuel filter can effectively extend the life of equipment, reduce maintenance costs and save money for users.

5. equipment warranty period, and the service life has been long, is not necessary to use high quality excellent filter?

It's easier to wear the equipment engine, causing cylinder. Therefore, the old equipment needs high quality filter core to stabilize the gradual wear and tear and maintain the performance of the engine.

Otherwise, you'll have to spend a lot of money on repairs, or you'll have to scrap your engine ahead of time. Through the use of pure filter core, can ensure that you spent the total operating costs (maintenance, maintenance, overhaul and depreciation of the total cost) minimum, but also to extend the service life of the engine.

6. filter as long as cheap, can be installed on the engine well on it?

The size and appearance of many domestic manufacturers of geometric filter will simply copy the original pieces, and the filter should be the standard engineering importance, even don't know what is the content of the standard project.

When the filter core is designed, in order to protect the engine system, if the performance of the filter can not meet the technical requirements and lose the filtering effect, then the performance of the engine will be significantly reduced, and shorten the service life of the engine.

For example, the life of a diesel engine is directly related to the engine damage in advance of "eating" into the 110-230 grams of dust. As a result, inefficient, inferior filter elements will allow more magazines to enter the engine system, resulting in an early overhaul of the engine.

7., the filter used does not cause any problems in the machine, so the user is not necessary to buy more money to buy good quality?

The effect of low efficiency inferior filter elements on the engine may not be immediately apparent to you. The engine seems to be running well, but harmful impurities may have entered the engine system and have begun to cause corrosion, rust, wear, etc. of engine parts.

These injuries are recessive and will break out when accumulated to a certain extent. Although there is no sign now, it does not mean that the problem does not exist. It may be too late to find a problem. Therefore, the use of high quality, guaranteed pure filter elements ensures maximum protection of the engine.

The air filter is located in the intake system of the engine, its main function is to remove harmful impurities in the air entering the cylinder, in order to reduce the early wear of cylinder, piston, piston rings, valve and valve seat, so as to provide guarantee for the normal operation, the output power of motor.

In general, the air filter used by different models of different replacement time, but when the filter clogging indicator lights up, must clean air filter. If the working environment is bad, the period of replacement of the filter elements inside and outside the air should be shortened.
