Liquid filter bag burst reason


Pressure problem: the operating pressure should be within the allowable range, the pressure difference should be carried out in accordance with the provisions, there are two ways to see the pressure difference, one is a relatively cheap mechanical pressure gauge, but the error is very large, the other is the flow meter, the cost is a little higher.


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.


Filter bag use problem: filter bag in the filter is not fixed, with the rotation of liquid is moving, filter bag burst in the elimination of pressure and work and accident circumstances, the polishing degree of the filter basket also determines the use of filter bag, filter system design will also lead to improper bag burst.


Accidents and material problems: improper installation of filter bags, improper use of operators, and defective filter design will lead to the burst of filter bags. In addition, improper material selection will cause damage to the use of filter bags.
