The air filter is a filter, also known as air filter, air filter, style, etc. Mainly used in engineering locomotives, automotive, agricultural locomotives, laboratory, sterile operation charts, and air filtration in various precision operating rooms.

The engine should suck a large amount of air during operation. If the air is not filtered, the suspended dust in the air is inhaled in the cylinder, and the wear of the piston group and the cylinder will be accelerated. The larger particles enter the piston and the cylinders, which can cause serious "pull tank" phenomena, which is particularly serious in the drying and sandwatch. The air cleaner is mounted in front of the oil or intake pipe, which functions as dust and granulation in the air, ensuring that the cylinder enters the sufficient amount, cleaner air.

3.Product Feature and application+Installation and maintenance

A) At the time of installation, the air filter and the engine intake pipe must be tight and reliable, prevent leakage, and the filter belt must be installed in both ends of the filter. Fixed air filter The airfoil nut of the outer cover cannot be screwed, so as not to press the bad paper filter.

B) At maintenance, the paper filter can not be placed in oil, otherwise the paper filter will fail, and it is easy to cause a speed of the car. When maintenance, only the vibration method can be used, and the brush brush is removed (to brush its wrinkle brush) or the compressed air back blow method is removed from dust and dirt at the surface of the paper filter. For the rough filter part, dust in the dust elimination, blade and cyclone tube should be removed in time. Even if it is carefully maintained every time, the paper filter cannot completely restore the original performance, and its intake resistance will increase, so, when the paper filter needs to be maintained for the 4th maintenance, the new filter should be replaced. If the paper filter is ruptured, the perforation or filter paper and end cap de rubse should be replaced immediately.

C) In use, strictly prevent the paper core air filter by rain, because once the paper core adsorbs a lot of moisture, it will greatly increase the intake resistance and shorten the mission. In addition, the paper core air filter cannot be in contact with the oil and fire.

D) Some vehicle engines are equipped with a cyclone air filter. The plastic cover of the paper filter end is a guide cover. The blades on the cover make the air rotate, and 80% dust is separated under the action of centrifugation, collecting in the dust cup, The dust reaching the paper filter is 20% of the amount of dust inhaled, and the total filter efficiency is about 99.7%. Therefore, when maintaining a cyclone air filter, be careful not to drain the plastic flow cover on the filter.

1. The filter element is the core component of the filter, made from special materials, belonging to the loss, requiring special maintenance, maintenance;

2. After the filter is working for a long time, the filter element has intercepted certain impurities, which will cause the pressure to increase, the flow rate is reduced, and it needs timely cleaning at this time;

3. When cleaning, be careful not to deform or damage the filter.

It is generally different depending on the use of the raw materials used, but with the extension of the use time, the impurities in the air will block the filter element, so in general, the PP filter needs to be replaced for three months; the activated carbon filter is required for six months Replacement; while the fiber filter cannot be cleaned, it is generally placed in the rear end of PP cotton and activated carbon, it is not easy to cause clogging; the ceramic filter can usually use 9-12 months.
