Installation and use of air filter

Air filter element is a kind of filter, also called air filter cartridge, air filter, style, etc.

Mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms.

The engine takes in a lot of air during its work.

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 assembly and the cylinder.

Larger particles entering between the piston and the cylinder will cause serious “cylinder pull” phenomenon, which is especially serious in a dry and sandy working environment.

The air filter is installed in front of the carburetor or the air intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.

Install and use

1.When installing, whether the air filter and the engine intake pipe are connected by flanges, rubber pipes or directly, they must be tight and reliable to prevent air leakage.

Rubber washers must be installed on both ends of the filter element; fixed air filter The wing nut of the outer cover of the filter should not be tightened too tightly to avoid crushing the paper filter element.

2.During maintenance, the paper filter element must not be cleaned in oil, otherwise the paper filter element will become invalid and easily cause a speed accident.

During maintenance, only use vibration method, soft brush removal method (to brush along the crease) or compressed air blowback method to remove dust and dirt attached to the surface of the paper filter element.

For the coarse filter part, the dust in the dust collection part, blades and cyclone tube should be removed in time.

Even if it can be carefully maintained every time, the paper filter element cannot fully restore its original performance, and its air intake resistance will increase.

Therefore, generally when the paper filter element needs to be maintained for the fourth time, it should be replaced with a new filter element.

If the paper filter element is broken, perforated, or the filter paper and the end cap are degummed, it should be replaced immediately.

3.When in use, it is necessary to strictly prevent the paper core air filter from being wetted by rain.

Because once the paper core absorbs a large amount of water, it will greatly increase the air intake resistance and shorten the mission.

In addition, the paper core air filter should not be in contact with oil and fire.

4.Some vehicle engines are equipped with cyclone air filters. The plastic cover at the end of the paper filter element is a diversion cover.

The blades on the cover make the air rotate. 80% of the dust is separated under the action of centrifugal force and collected in the dust collector.

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 flow cover on the filter element.
