【Meiruier Filter】What's the difference between primary diesel filter and diesel

2021-08-19 View:

The difference between primary diesel filter and diesel filter:
1. As the main filter in the two-stage filtration, the diesel fine filter is also the last line of defense against impurities. It has high requirements for filtration efficiency and service life;
2. At present, for diesel heavy trucks of the National Three Standards, the filtration efficiency of 35 micron particles is required to be as high as 98.6%, the filtration efficiency of particles above 510 microns is 99.8%, and the filtration efficiency of particles above 10 microns is required to be 99.9%;
3. While ensuring high filtration efficiency, it must also meet small flow resistance to ensure the reliable operation of the engine and sufficient power;
4. Strainer is mainly used to retain large particles. Most hydraulic systems have strainers from the tank inlet to the pump suction inlet. The coarse filter is used to replace the general filter, because the general filter will be blocked, and the pump water or other media cannot enter the pump if it is "starved";
5. But because the coarse filter is installed inside the fuel tank, the maintenance of the coarse filter is often overlooked. When silt and heavy dust gather on the strainer of the suction inlet, the pump will quickly cavitation, and it is prone to malfunction.
