Protect our lungs and talk about air filters that are easily overlooked

Today, with the spread of PM2.5, various masks that have a protective effect on PM2.5 have appeared on the scene, becoming the main "weapons" against the haze in daily life. Once the body inhales harmful substances excessively, it will have a major impact on health. Then, for the engine, the dust is the main cause of the early wear of the engine. The air filter is equivalent to the mask we wear to isolate the harmful substances in the air, and it plays the role of filtering dust and sand in the air to ensure the cylinder. Enter enough, clean air.
Because the air filter can be used continuously for a long time without maintenance, the replacement cycle is also long. Many construction machinery users tend to neglect to maintain it during use. Sometimes, when the alarm is blocked, it will be remembered. It is cleaned or replaced. Among the many components of construction machinery, the air filter may be a very inconspicuous part. However, air filters play a vital role in construction machinery and equipment. They can directly affect important parts of engine life and are one of the important reasons for engine failure.

Regular maintenance of the air filter can greatly improve engine performance and extend engine life.

Construction machinery and equipment are mostly used in municipal construction, mining and other high dust working environment. The engine should absorb a lot of air during the working process. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, which will accelerate the piston group. And the wear of the cylinder. Larger particles enter between the piston and the cylinder, and can even cause severe "pull-cylinder" phenomena, which is especially serious in dry and sandy working environments. The installation of the air filter is the main means to solve this problem. After the air filter is used for a period of time, due to the increase of the amount of dust adhering to the filter element, the intake resistance will increase, and the intake air will decrease, making the engine Performance is declining. Therefore, the filter element of the air filter must be regularly maintained and maintained. Under normal circumstances, the maintenance period of the air filter used in construction machinery and equipment is: clean the outer filter element of the filter every 250 hours, and replace the inner and outer filter elements after each cleaning for 6 times or after 1 year.

The specific steps for cleaning the air filter are as follows: remove the end cap, remove the outer filter to clean it, and remove the dust on the paper air filter, apply a soft brush to remove the dust on the surface of the filter element along the direction of the crease. Gently tap the end face to remove the dust. It should be noted that: when removing ash, use a clean cotton cloth or rubber stopper to block the two ends of the filter element to prevent dust from falling into the filter element. A better method is to compress the air machine or the air pump (the air pressure must not exceed 0.2-0.3MPA, Anti-corruption filter paper) Blows air from inside the filter element to blow off dust adhering to the outer surface of the filter element. The dry air filter uses water or diesel or gasoline to clean the paper filter. Otherwise, the filter element pores are blocked and air is added.

In the air filter instruction manual, the working hours are specified as data for maintenance or replacement. However, the maintenance and replacement cycle of the air filter is actually related to environmental factors. Frequently working in an environment with a lot of dust, the replacement cycle should be shortened slightly; in actual work, many owners will not be flexible according to different factors such as the environment, and even the outside of the air filter will continue to be used as long as it is not damaged. It should be noted that the air filter will fail. At this time, maintenance will not be able to recover the damage already caused. Buying an air filter is not worth much, and if the engine is damaged, it will not be worth the loss. When removing dust from the air filter, when the filter paper is seriously damaged, damaged, or the upper and lower end faces of the filter element are not flat or the rubber seal ring is aging and deformed, new parts should be replaced.

What is the danger of false air filtration, how to identify true and false air filters?

Because the air filter is simple in process and low in production cost, it is extremely easy to be imitated. It is understood that the air filter is currently filled with more than 80% of counterfeit goods in the market, and the fake filter element is made of cheap low-quality non-woven fabric. Or it is made of low-quality or even counterfeit activated carbon, the cost is less than 10 yuan. This kind of filter element not only does not have good protection effect on the machine, and even some workmanship is inferior in the process of using slag. Directly enter the engine, causing damage to the engine.
Xiaobian here to share with you a simple true and false air filter identification method, open the package with a pungent smell of recycled plastic, must be fake, genuine air filter has no pungent taste. The overall workmanship of the filter element is not neat, the filter paper is not arranged neatly, and there is obvious flaw. The thin material can be judged as a fake. The filter paper of the genuine filter has high regularity, thick material and strong air permeability. Secondly, you can look at the package, look at the code, and check the serial number of the Internet to identify the authenticity. In addition to the above, there are some high-efficiency air filters on the market, which are not suitable for identification. Therefore, users are advised to find regular channels and trusted suppliers when purchasing air filters.

to sum up

Many engineering machinery owners are more concerned about what kind of machine filter and diesel filter they use on a daily basis, but they are more casual about air filters. After reading this article, you may already understand the importance of air filter, for the engine. In terms of no good air filtration, it is no good to use even the best machine filter and diesel filter. Secondly, Xiao Bian would like to appeal to all colleagues in the industry to consider using genuine parts when purchasing maintenance parts. The price of a set of genuine maintenance parts may be much higher than the price of a set of deputy parts, but it is nothing more than It’s a few hundred dollars, compared to millions of construction machinery and equipment, it’s really very small. Even if an excavator is working for more than one hundred hours, the cost of maintenance parts for life will come back. You said Is it such a thing?
