The filter  bag length is too long will cause the lower part of the filter bag wear, especially the bag bottom up within 100㎜, mainly dust bag length more than the bag cage length of more than 30㎜, the filter bag in the filter shrinkage is too large, the filter bag bottom up 100㎜, and the bottom of the bag cage friction, eventually wear the bag. Damage marks are mostly from inside to outside, in the lower fold of the bag damage.

Bag spring ring is related to the seal of filter bag, bearing and other important links, spring piece breakage occurs in dust bag storage improper spring piece oxidation rust or spring piece steel is too hard and brittle, the former belongs to the customer's reason, the latter belongs to the supplier's reason. If the spring plate is too soft, as long as it does not affect the installation of the filter bag, there is no problem. If it cannot be installed, please replace it with the supplier.

Sewing thread breakage is mostly caused by wear, and there are obvious wear marks on the fracture surface. It is also caused by different materials of sewing thread and filter bag, but the probability of this situation is very low, and the fracture surface is in the form of crushing or strong falling fracture.

Bag detection: professional inspection tools, perfect quality inspection system, to ensure the quality of each dust filter bag.

THE COMPETITION OF FILTER MATERIAL MARKET IS FIERCER DAY BY DAY, MANY MANUFACTURERS DISCOUNT GREATLY FROM QUALITY RESPECT, REMIND BROAD USER HERE ESPECIALLY WHEN ORDERING DUST COLLECTOR CLOTH BAG TO PAY ATTENTION TO THE FOLLOWING MATTERS.


Dust filter bag from raw materials to finished products need a lot of processes, each process needs to be strictly checked, if the filter bag quality problems, more in the filter bag raw material, bag diameter, bag length, bag spring coil, sewing line.

The wrong use of dust filter bag raw materials is the lowest level of the supplier's mistake, but there are a few suppliers to make up the number in order to save costs. All the filter materials on the filter bag should be made of the same material. High-grade materials can be used instead, but low-grade materials can not be used. For example, PTFE sewing thread is acceptable for PPS filter bag, but glass fiber sewing thread is not.

The diameter of the bag mouth determines the tightness of the filter bag and the porous plate. In the process of new filter bag, the supplier and customer should communicate well to avoid mistakes. If the diameter of the bag mouth is too large, you can cut the filter material at the groove of the bag mouth equilateral distance, the length of the removal should not exceed 20mm, reduce the outer diameter of the bag mouth for installation. If the diameter of the bag mouth is too small, you can outsource 300 ~ 400㎜ edge of the same material at the bag mouth, and the length of the edge is adjusted according to the tightness of the installation filter  bag mouth.
