Installation and use

1. During installation, whether the air filter and the engine intake pipe are connected by a flange, a rubber tube or a direct connection, it must be tight and reliable to prevent air leakage. Rubber gaskets must be installed on both ends of the filter element; fix the air filter The wing nut of the filter cover should not be over-tightened, so as not to crush the paper filter element.

2. During maintenance, 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, the dust and dirt attached to the surface of the paper filter element can only be removed by vibration method, soft brush removal method (brush along its creases) or compressed air back blowing method. For the coarse filter part, the dust in the dust collection parts, blades and cyclone pipes 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, when the paper filter element needs to be maintained for the fourth time, it should be replaced with a new one. If the paper filter element is cracked, perforated, or the filter paper is debonded from the end cap, 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 air intake resistance and shorten the working time. In addition, the paper core air filter cannot be in contact with oil and fire.

4. 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 cup. The dust that reaches 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.

maintenance

1. The filter element is the core component of the filter. It is made of special materials and is a vulnerable part that requires special maintenance and maintenance;

2. After the filter has been working for a long time, the filter element has intercepted certain impurities, which will lead to an increase in pressure and a decrease in flow rate. At this time, it needs to be cleaned in time;

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

Generally, according to the different raw materials used, the service life of the filter element is also different, but as the use time prolongs, impurities in the air will block the filter element, so generally speaking, the PP filter element needs to be replaced every three months; the activated carbon filter element needs to be replaced after six months. Replacement; because the fiber filter element cannot be cleaned, it is generally placed behind the PP cotton and activated carbon for use, which is not easy to cause blockage; the ceramic filter element can usually be used for 9-12 months.

The filter paper in the equipment is also one of the keys. The filter paper in high-quality filter equipment usually uses ultra-fine fiber paper filled with synthetic resin, which can effectively filter impurities and has a strong ability to store dirt. According to relevant statistics, when a passenger car with an output power of 180 kilowatts travels 30,000 kilometers, the impurities filtered out by the filter 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 air flow, the strength of the filter paper can resist the strong air flow, ensure the filtration efficiency and prolong the service life of the equipment.
