b. Diesel filter original filtration efficiency

c. Blockage life of diesel filter assembly stand

d. Engine filter original filtraton effciency

【Equipment introduction】

Filter Testing Equipment is used to determine the ability of fuel oil filter to filter test impurities under specified test conditions, it represents the relative percentage of test impurities filtered by the filter and the added test impurities; Filter Testing Equipment is also used to determine the time and cumulative oil amount when the pressure difference reaches 0.07 MPa of the time that test liquid containing the specified impurities is passed through the fuel filter as a filter plugging test at a specified volume flow rate. The original filtration efficiency test shall be carried out after the cleanliness test, the bubble test, the original resistance test and the sealing test. Filter Testing Equipment blocking up life test shall be carried out after the cleanliness test, the original resistance test, the sealing test and the original filtration efficiency test.
