ADD: No.13 Dongping Middle Road, Baiyun District, Guangzhou, China
1. Replacing oil-resistant rubber parts with ordinary rubber parts, the early wear and tear of the engine caused by the short-circuit of the filter caused by the seal failure of the internal seals or the expansion and deformation of the external seals, resulting in the extrusion of the outer seal ring of the oil filter, a large amount of oil leakage in a short time, so that the engine burns tiles and holds the shaft. Suffered serious damage.
2. Spot welding replaces seam welding at the welded parts of the air filter shell, which can not guarantee the sealing and form a short circuit.
3. The material of the central pipe of the oil filter is thin instead of thick, and the strength is not enough. In the course of using, the central pipe is sucked out, the filter core is broken and blocked the oil circuit, resulting in insufficient lubrication of the engine; or the reliability of the bite is poor, and the bite is pulled open in the course of using, resulting in a large amount of oil leakage in a short period of time, thus causing tile burning and shaft holding.
4. Using low-priced filter paper to make filter element, because of its large aperture, poor uniformity and low filtration efficiency, it can not effectively remove harmful impurities from the engine, resulting in early engine wear.
5. Use low-quality adhesives, and the amount is very small, neither oil-resistant, and can not be firmly bonded, resulting in short-circuit filter element bonding; or filter element joint using stapler connection, can not seal and short-circuit, so that a large number of harmful impurities into the engine, reduce engine life
6. Replacing oil-resistant rubber parts with ordinary rubber parts, the early wear and tear of the engine caused by the short-circuit of the filter caused by the sealing failure of the inner seal or the expansion and deformation of the outer seal, resulting in the extrusion of the outer seal ring of the oil filter, a large amount of oil discharged in a short time, resulting in the burning of the engine Bush and the holding shaft. Suffered serious damage.
