The cause of the explosion of liquid filter bag
Mar 20, 2018

1. Pressure problem: the operating pressure should be within the allowable range, and the pressure difference should be carried out in accordance with the regulations. There are two ways to see the pressure difference, one is a relatively low mechanical pressure gauge, but the other is a Flowmeter, the cost is slightly higher.

2. The filter bag itself is a problem of workmanship. At present, the making of the filter bag is divided into hot melt welding and wire sewing. The pressure on the hot melt welding is about 10 kilograms, and the triangle bottom is more resistant to pressure than the circular arc, and the seam workmanship bears about 16 kilograms of pressure. However, if the jumper or take-off is easy to burst the bag, the filter bag will increase in pressure loss, impurity fouling, and test the material and workmanship of the filter bag.

3.Filter bag use problem: the filter bag is not fixed in the filter, as the liquid rotates, the filter bag explodes under the condition of removing pressure and workmanship and accident, and the polishing degree of the filter basket also determines the use of the filter bag. Improper design of filtration system will also lead to bag explosion.

4.Unexpected and filter material problems: the filter bag is not installed correctly, or the operator uses it incorrectly, as well as the filter design is defective, there will be filter bag burst problem, and the material selection will cause more damage to the filter bag use.
