Backwash filter water intrusion method Test principle: water intrusion method dedicated to the test of the hydrophobic filter, the hydrophobic membrane to resist water, the smaller the aperture, and to squeeze the water the greater the pressu re required in the hydrophobic membrane. Therefore, under a certain pressure, the measurement to squeeze into the water flow in the membrane to determine the pore size of the filter element.
Automatic self-cleaning filter test principle bubble point testing theory: When the membranes and filter the solution completely wet, then through the pressure of the gas source on one side (our instrument intake control system, can stabilize the pressure adjusting the intake), as the pressure increases, the gas is discharged from one side of the membranes, the performance of the film side of the size, number ranging bubbles through the instrument determines that the corresponding pressure value is the bubble point.
Why diffusion flow better: bubble point value is only a qualitative value, foaming from the beginning to the final group of blistering is a long process, not an accurate quantitative. And measuring the diffusion flow value is a quantitative value, not only can accur ately determine the integrity of the filter, but also the reaction of the porosity of the film, the automatic brush filter Gao Road work workmanship high quality filtration equipment traffic and effective filtration area, and other aspects of the problem, which is why foreign manufacturers are using the the diffusion flow method test the integrity of the reasons.
A diffusion flow testing theory: diffusion flow test is that when the gas pressure the filter bubble point value of 80%, when is not a large amount of gas perforated over only a small amount of gas is first dissolved in a liquid phase separator , then spread to the other side of the vapor phase from the liquid phase, this part of the gas known as diffusion flow.glass fiber fabric
