What is the cause of the liquid filter bag
Filter bag use: filter bag into the filter is not fixed, as the rotation of the fluid is moving, filter bag burst bag out pressure and work as well as the accident cases, the degree of polishing filter basket also determines the use of filter bag, filter system of poorly designed can also lead to explosive bag, etc.
Filter bag itself problem: workmanship problem, filter bag currently do manual work is divided into hot melt welding and line sewing, hot melt welding stress is about 10 kg, and at the bottom of the triangle than arc pressure, seam about 16 kilograms to work under pressure, but if the jump line or off line easy to bag, pressure loss of the filter bag at run time will increase, the impurity scale, very test of the filter bag material and workmanship.
Pressure problem: operating pressure is within the scope of the permit, the differential pressure to be executed in accordance with the relevant provisions, there are two ways to look at the differential, a mechanical pressure gauge is relatively low, but the error is very large, another is the flowmeter, costs a little high.
Accident and material problems: filter bag when installation is not correct, improper use or operators, and there are defects will filter bag filter design problem, the other material choice can no more harm the filter bag use.
