A, rotary filter period
Spin pack filter is developed in the 1970 s with filter paper as filter material filter varieties. Rotary filter structure is compact, light weight, reliable operation, convenient maintenance, is widely used in automobiles, tractors, combine harvesters, engineering machinery engines. Spin pack filter including spin machine oil filter diesel filter and spin. Oil, fuel that is installed by the oil filter or spin pack diesel filter, depending on the filter when gravity deposition, aggregation, adhesion, diffusion mechanism, filter out the impurity in the oil and water.
First in the history of Chinese spin pack filter production line by the Italian castle group (Sophie brand owned by the Philippines group) sell to bengbu factory in 1982, and provide the most advanced production equipment for the technical support. The China agricultural machinery production of filter manufacturers now become China's leading automotive filter manufacturer. Since then, bengbu developed automotive filter manufacturers have sprung up, the mature scale until today.
Second, the period of efi fuel filter
The fuel filter of before 1996, China is still at the carburetor and fuel filter of adsorption phase. Castle group with European advanced at the time of efi fuel filter technology (the technology is still occupy the leading position), a light spot in view of the Chinese market for this technology and strong demand, the group decided to invest in China. Now China's leading domestic auto start to enjoy the Philippines group efi fuel technology (S1500B and S1718B) is the first project. With the world's leading efi fuel technology, in the stage of a castle group coverage once more than 80% market share.
Three, the filter module
In the design of the traditional engine lubrication system, oil filter and oil cooler respectively as two separate assembly installed on the engine cylinder block, using external or internal channel pipe connected between them. In modern cars, due to the limitation of the engine installation space, require the structure of the attachment is very compact. The usual solution is to set the two assembly together. Modular technology was born.
With the strengthening of environmental protection consciousness, filter module technology is accepted by more and more car manufacturers. Sophie in filter module technology also continue to stay ahead, between 2004 and 2005 was successfully win the dragon Peugeot series TU5JP4 / EW10 oil module project. Sophie tamar oil filter in the oil module S5057PE was aftermarket, occupied high market share. In China's current oil module project, Sophie, she once again created the same achievements and efi fuel filter, accounted for 80% of the market.
