Air filter is an important part of air compressor maintenance. However, there are many brands of air filters on the market, and the quality is uneven, and many people buy poor quality products in order to be cheap, so what impact does the poor quality air filter have on the engine?
1. Spot welding is used instead of seam welding at the welding of the air filter shell, which cannot ensure the tightness, forming a short circuit and causing damage.
The end cover of the filter element, the center tube, the shell and other metal parts are not treated with rust prevention, causing metal corrosion and impurities, making the filter a source of pollution, and what is more, replacing the cement with the adhesive is more harmful.
2, the use of low-cost filter paper to make filter element, because of its large aperture, poor uniformity, low filtration efficiency, can not effectively remove harmful impurities in the engine, resulting in early engine wear.
3, the oil filter center pipe material is not thick, not thin, strength is not enough. In the process of use, because the center pipe is sucked out, the filter element breaks and blocks the oil circuit, resulting in insufficient engine lubrication; Or poor occlusal reliability, occlusal is pulled apart during use, resulting in a large amount of oil leakage in a short period of time, resulting in tile burning and shaft holding.
4, the use of inferior adhesive, and the amount is very small, neither oil resistance, and can not be firmly bonded, resulting in short circuit bonding filter element; Or the filter joint is connected with a clamp, which can not be sealed and short circuit, so that a large number of harmful impurities enter the engine and reduce the engine life.
5, the use of ordinary rubber parts instead of oil-resistant rubber parts, early engine wear, internal seal seal failure causes the filter internal short circuit resulting in the outer seal life reduction or expansion deformation, resulting in the outer seal extruding the oil filter ring, a large amount of oil in a short time, so that the engine burning tile, holding the shaft. Suffered serious damage.
Mengma filter adopts imported top filter paper with high filtration accuracy. Adopt high strength steel plate, sandblasting treatment, make the bonding more firm. Using top glue and automatic injection molding machine processing, with higher stability. With high strength steel plate and spiral processing technology, the support strength is higher and the pressure difference can withstand 5bar. Mature technology, after many tests, can be applied to 5-10bar working pressure. Graphite gaskets have better sealing and electrical conductivity.
