Inferior filter in the filter is good or bad - flaw 【 3 m filter.

Filter is an important part of the filter, pp cotton filter manufacturers often can expose the filter of the problem.

　　1. Using low price of filter paper filter, because of its large filter aperture, poor uniformity and low filtration efficiency, polypropylene filter on the engine can not be effectively filter harmful impurities, cause the engine early wear.

　　2. Use low-quality adhesive, and dosage is very few, neither oil resistant, but not strong adhesive, shorting filter stick it; Use staples or filter the joint connection, unable to seal and short circuit, make a lot of harmful impurities into the engine, reduce engine life.

　　3. To ordinary rubber instead of oil resistant rubber parts, 3 m large flow filter in the process of using or filter internal short circuit formed by the internal seal seal failure cause engine early wear and cutting life or expansion deformation of external the seals, causing oil filter outside sealing ring out, a short time, a large number of drainage, make the engine burn watts, holding shaft, suffered severe damage.

　　4. Empty filter shell parts welding with alternative spot welding seam welding, 3 m rigid PP filter cannot assure tightness, form a short circuit.

　　5. With thin and thick oil filter center tube material, strength is not enough, in use process because of center pipe, flat absorption filter breakage blocking oil, the engine lubrication; Or bite poor reliability, bite mouth opened in use process, the oil in a short time, a large number of leakage, thus cause the tile burning, holding shaft.

　　6. Filter plate, center pipe, casing and other metal parts, without antirust processing, cause metal corrosion impurities, the filter into a pollution source. More serious filter manufacturers, in order to cement instead of adhesive, its harm is greater. Everyone in determining when a filter is good or bad must give priority to with the quality of the filter element. A good filter is very important.

with thin and thick oil filter center tube material, strength is not enough, in use process because of center pipe, flat absorption filter breakage blocking oil, the engine lubrication; Or bite poor reliability, bite mouth opened in use process, the oil in a short time, a large number of leakage, thus cause the tile burning, holding shaft.
