Installation and use of air filter

Air filter element is a type of filter, also known as air filter cartridge, air filter, style, etc. Mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms.

The air filter engine needs to suck in a lot of air during the working process. If the air is not filtered, the dust suspended in the air is sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can cause serious "pulling the cylinder", which is especially serious in dry and sandy working environments.

The air filter is installed in front of the carburetor or the intake pipe, and plays the role of filtering out dust and sand in the air, so as to ensure that sufficient and clean air enters the cylinder.

Air filter installation and use

1. When the air filter element is installed, whether it is connected by flange, rubber pipe or direct connection between the air filter and the engine intake pipe, it needs to be tight and reliable to prevent air leakage. Rubber gaskets must be installed on both ends of the filter element; Do not overtighten the wing nut of the filter housing to avoid crushing the paper filter element

2. During the maintenance of the air filter element, the paper filter element must not be cleaned in oil, otherwise the paper filter element will fail, and it is easy to cause a speeding accident. During maintenance, only use the vibration method, the soft brushing method or the compressed air blowback method to remove the dust and dirt attached to the surface of the paper filter element.

3. When the air filter element is in use, it is necessary to strictly prevent the paper core air filter from being wet by rain, because once the paper core absorbs a lot of water, it will greatly increase the air intake resistance and shorten the mission. In addition, the paper core air filter must not come into contact with oil and fire.

Some vehicle engines are equipped with a cyclone air filter. The plastic cover at the end of the paper filter element is a shroud. The blades on the cover make the air rotate, and 80% of the dust is separated under the action of centrifugal force and collected in the dust collector. Among them, the dust reaching the paper filter element is 20% of the inhaled dust, and the total filtration efficiency is about 99.7%. Therefore, when maintaining the cyclone air filter, be careful not to miss the plastic shroud on the filter element.
