What is the difference between the selection basis of the water filter element and the dust removal filter element?

In terms of dust filter, dust filter element plays a key role. So, what kind of dust filter is more suitable? The Lvyuan water filter element manufacturer analyzes the characteristics of the dust filter element and shows you the basis for choosing the dust filter element. 1. Rated air intake. The air chlorine flow rate in the technical parameters of the dust filter element should be greater than the rated intake air volume of the equipped engine. 2. Dust removal filter element filter material. There are requirements for the thickness, tension resistance, original air intake resistance and filtration accuracy of the filter material of the dust removal filter element. Imported diesel requires air filtration accuracy of 5μm, and domestic diesel engines should also be less than 20μm. The filtration accuracy of high-efficiency filter paper is 2μm, the ordinary imported filter paper is 30μm, and the domestic dust filter cartridge filter paper is only 80μm. 3. Performance test of dust removal filter element. ① Flow-resistance (pressure drop) test Determine the air flow pressure loss (flow-resistance or flow-pressure curve). ②In the original filtration efficiency test, the dust collection efficiency of the dust filter element can be calculated, and the dust reduction rate of the normal dust filter element should be more than 99%. ③Dust storage capacity test and cumulative efficiency test. Excessive dust accumulation in the dust removal filter will cause blockage and increase the air intake resistance. The air intake resistance when the engine power is reduced by 5% or the fuel consumption is increased by 5% is a limit value. When this value is reached, the dust filter element must be cleaned or replaced. During the test, the dust weight when the air intake resistance or pressure drop reaches 7-46kPa is the dust storage capacity of the dust removal filter element, and the filtration efficiency during this test is the cumulative efficiency. ④In the original air intake resistance test, the pressure difference between the inlet and outlet when the air volume at the rated air intake resistance passes through the dust filter element) should not exceed 3.2kPa, and the power will drop and the engine will emit black smoke.
