Air filter element.
Air filter element is a kind of filter, also called air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operation rooms and various precision operation rooms.
The engine in the working process to suck in a lot of air, if the air is not filtered clear, the suspended dust in the air is sucked into the cylinder, it will accelerate the piston group and cylinder wear. Larger particles entering between the piston and the cylinder will cause a serious "cylinder pulling" phenomenon, which is particularly serious in a dry and sandy working environment. The air filter is installed in the front of the carburetor or the intake pipe to filter the dust and sand in the air to ensure that sufficient and clean air is entered into the cylinder.
Installation and use
1. During installation, whether the air filter and the engine intake pipe are connected by flanges, rubber tubes or direct connections, they must be tight and reliable to prevent air leakage, and rubber gaskets must be installed on both ends of the filter element; The wing nut holding the air filter outer cover should not be screwed too tightly to avoid crushing the paper filter element.
2. In the maintenance, the paper filter must not be cleaned in the oil, otherwise the paper filter will fail, and it is easy to cause a car accident. Maintenance, only use the vibration method, soft brush removal (along with its crease brush) or compressed air blowback method to remove dust and dirt attached to the surface of the paper filter. For the coarse filter part, the dust in the dust collecting part, the blade and the cyclone tube should be removed in time. Even if each time can be carefully maintained, the paper filter can not fully restore the original performance, the air intake resistance will increase, therefore, generally when the paper filter needs to carry out the fourth maintenance, it should be replaced with a new filter. If the paper filter element is broken, perforated, or the filter paper and the end cap are degumming, it should be replaced immediately.
3. When in use, it is necessary to 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 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 a whirlwind air filter, the plastic cover at the end of the paper filter element is a diversion cover, the blade on the cover makes the air rotate, 80% of the dust is separated under the action of centrifugal force, collected in the dust collection cup, the dust reaching the paper filter element is 20% of the amount of dust inhaled, the total filtration efficiency is about 99.7%. Therefore, when maintaining the whirlwind air filter, be careful not to leak the plastic deflector on the filter element.
maintenance
1, the filter element is the core component of the filter, made of special materials, belongs to the wearing parts, need special maintenance, maintenance;
2, when the filter has been working for a long time, the filter element has intercepted a certain amount of impurities, which will lead to an increase in pressure and a decrease in flow, at this time, it is necessary to clean in time;
3, when cleaning, be sure to pay attention to the filter element can not be deformed or damaged.
Generally, according to the different raw materials used, the service life of the filter element is different, but with the extension of the use time, impurities in the air will block the filter element, so in general, PP filter element needs to be replaced for three months; The activated carbon filter needs to be replaced in six months; Because the fiber filter can not be cleaned, it is generally placed in the back end of PP cotton and activated carbon, which is not easy to cause blockage; Ceramic filters can usually be used for 9-12 months.
The filter paper in the equipment is also one of the key, and the filter paper in the high-quality filter equipment is usually filled with microfiber paper filled with synthetic resin, which can effectively filter impurities and have a strong pollution storage capacity. According to relevant statistics, a bus with an output power of 180 kilowatts travels 30,000 kilometers, and the impurities filtered out by the filtration equipment are about 1.5 kilograms. In addition, the equipment also has great requirements for the strength of the filter paper, due to the large flow of air, the strength of the filter paper can resist the strong airflow, ensure the efficiency of filtration, and extend the service life of the equipment.
