Dust bag from the raw material to the finished product requires a lot of processes, each process needs to be strictly controlled, if the filter bag quality problems, appear in the filter bag material, bag mouth diameter, filter bag length, bag mouth spring coil, sewing thread and so on.
Dust bag processing need to pay attention to matters:
1. The bag spring coil is related to the important aspects such as the sealing and load-bearing of the filter bag. The spring chip breakage occurs when the dust bag is stored improperly, the spring piece is oxidized or the spring piece is too hard and brittle. If the spring piece is soft, there is no problem if it does not affect the installation of the filter bag. If it cannot be installed, it needs to be replaced with the supplier.
2. The length of the bag will cause the lower part of the filter bag to wear out, especially within 100mm from the bottom of the bag. The main reason is that the length of the dust bag exceeds the length of the bag by more than 30mm. The filter bag shrinks too much during filtration and the bottom of the filter bag is 100 Mm, will rub with the bottom of the cage, and eventually wear the bag. The signs of damage mostly from the inside to the outside, broken at the bottom of the bag wrinkles.
3. Most of the sewing thread breakage is caused by wear, and the fracture surface has obvious wear marks. There are also different sewing thread and filter bag materials, but the probability of this situation is very low, the fracture surface was crushed or strongly broken down.
