Cause of PTFE Filter Bag Damaged
1. The opening part of PTFE filter bag is damaged
Most of the damages at the open mouth of the filter bag are within 400 downward, and most of the damage marks are from inside to outside, even the bag head and bag body are separated. Cause: the damage is caused by too high compressed air, deflection of spray pipe, deformation of flower plate, etc. the damage can be avoided after adjustment.
2. PTFE filter bag body is damaged
If the damage trace is from inside to outside and the damage is on the vertical reinforcement of the bag cage, it indicates that the vertical reinforcement of the bag cage is desoldered or rusted, the filter bag is worn off, or the injection pressure is too high and the injection is too frequent, so that the contact position between the filter bag and the bag cage is folded, broken and damaged. Replacing the bag cage or adjusting the injection device can solve the problem.
3. The lower part of PTFE filter bag is damaged
The outer damage of the lower part of the filter bag is mostly found within 300mm upward from the bottom of the filter bag, and the damage is mostly on one side. The lower part is particularly serious and gradually reduces upward. The local sewing thread will be worn off, and the strength of the sewing thread is good where there is no wear. Such damages are often caused by deformation of perforated plates, too close spacing of perforated plates, deformation of bag cage, too long PTFE filter bag and so on. In some cases, the filter bag and the dust collector box wall are worn and damaged.
4. The bottom of PTFE filter bag is damaged
The bottom of PTFE filter bag is mostly damaged on the outside, and there are obvious wear marks on the damaged surface. The bottom sewing thread is worn off, and the filter material base cloth is worn off. In serious cases, the bag bottom is damaged or falls off as a whole. Adjust the ash unloading of the ash hopper of the dust remover to avoid excessive dust accumulation and vortex wear of the filter bag.
