【Meiruier Filter】The function of air filter

2021-05-18 View:

A device for removing particulate impurities in the air. When piston machinery (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts: a filter element and a shell. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance.

Effect: 

The 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 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 and ensure that sufficient and clean air enters the cylinder.
Among the tens of thousands of parts and components of the car, the air filter is a very inconspicuous component, because it is not directly related to the technical performance of the car, but in the actual use of the car, the air filter has a great influence on the service life of the car (especially the engine). On the one hand, if there is no filtering effect of the air filter, the engine will inhale a large amount of air containing dust and particles, causing serious wear of the engine cylinder; On the other hand, if it is not maintained for a long time during use, the filter element of the air filter will be filled with dust in the air, which will not only reduce the filtering capacity, but also hinder the circulation of air, causing the mixture to be too thick and causing the engine to work abnormally. Therefore, regular maintenance of the air filter is essential.
