In 2008, the top three Chinese heavy truck sales were China National Heavy Duty Truck, FAW, and Dongfeng; in 2009, FAW was the first to exceed Shouqi and Dongfeng ranked third. At the end of 2010, the sales volume of all heavy truck companies has basically settled. Looking at the sales of heavy trucks (including whole vehicles, non-integrated vehicles, and semitrailer tractors) in November of 2010 before major automobile companies, 2010 1- In November, the sales rankings of major mainstream heavy truck companies were: FAW, Dongfeng, CNHTC, Shaanxi Auto, Futian, Beiben, Hongyan, Hualing, and Jianghuai. FAW once again won the heavy truck sales championship with sales of 211,625 units and a 65% year-on-year growth rate. The sales performance of other companies is also quite satisfactory. 
The chart above shows that from January to November of 2010, except for SAIC Iveco Hongyan, there is still a little distance from the annual sales target, and most of the heavy truck companies' sales from January to November have far exceeded the targets set at the beginning of the year. Among them, FAW, Dongfeng, CNHTC, Valin and JAC performed particularly well. However, the sales growth of the auto makers in the second half of the year was far less than the year-on-year growth rate from January to June. This shows that the market in the second half of the year did not have the boom and boom of the first six months. 
From January to November 2010, the top three heavy truck sales were FAW, Dongfeng and CNHTC. Heavy truck slipped from the second place in the sales rankings in the third quarter, and the position of second place was occupied by Dongfeng. In view of this, the heavy truck sales throughout the year, the overall market structure of FAW, Dongfeng, heavy truck separated the top three has been set. Compared with the first half of 2010, the sales rankings of Shaanxi Auto, Futian, Beiben, Hongyan, Hualing and Jianghuai continued to remain stable.
In addition, in January-November 2010, Foton sold 96,687 heavy trucks, an increase of 30.71% year-on-year, making it the lowest growth among mainstream heavy truck companies. As a newcomer to the market, Jianghuai Gealfa ranks first in the heavy truck growth rate with a year-on-year growth of 96.09%. It seems that the prospect of JAC heavy truck is still worth the wait.
Precision filter is mainly composed of filter container, support basket and filter bag these three parts. It's made of stainless steel. Flange precision filter is divided into 1,2,3 and 4 filter bags according to the size of the filter bag. Liquid inlet and outlet direction is divided into side in bottom out type and bottom in bottom out type.
When the precision filter is working, the liquid enters the filter bag supported by the supporting mesh frame from the interface. The filter bag will be evenly expanded to the periphery by the impact of the liquid, so that the liquid can be evenly distributed on the inner surface of the whole filter bag. The liquid passes through the filter bag and is discharged from the outlet at the bottom of the filter. The filter residue is left to be intercepted in the filter bag.
When the filter bag can be replaced after running for a long time, or when the pressure difference between the inlet and outlet reaches 0.05-0.07mpa during use, the filter bag also needs to be replaced.
