Liquid filter bag burst bag causes

Analysis of the causes of bag burst filter bag.

Pressure problems: operating pressure to be within the allowable range, differential pressure to be implemented in accordance with the regulations, there are two ways to see the differential pressure, one is a relatively inexpensive mechanical pressure gauge, but the error is very large, the other is a flow meter, the cost is slightly higher.

Filter bag itself: the problem of workmanship, filter bag workmanship is currently divided into hot fusion welding and wire stitching, hot fusion welding to withstand the pressure is about 10 kg, and the bottom of the triangle than the circular arc pressure resistance, wire stitching workmanship to withstand the pressure of about 16 kg, but if the jump line or off the line is easy to burst the bag, the filter bag in the operation of the pressure loss will increase, impurities scaling, very test the filter bag material and workmanship.

Filter bag use problems: filter bag in the filter into the filter is not fixed, with the rotation of the liquid is moving, the filter bag burst in the exclusion of pressure and workmanship and accidents, the degree of polishing of the filter basket also determines the use of the filter bag, improper design of the filter system, etc. will also lead to burst bags.

Accidents and material problems: the filter bag in the installation is not correct, or operator improper use, as well as filter design defects will exist in the filter bag burst problem, in addition to the wrong choice of material will be more damage to the use of filter bags.
