Under normal circumstances, the dust bag is gradually worn, the main cause of wear is the grinding power of dust, high temperature caused by deterioration of the filter material and chemical corrosion, when the grinding power of dust is strong, the bottom of the bag wear the most serious , The system capacity increase caused by increased filtration speed can accelerate wear and tear. Dust collector can not use the damaged bag to work, otherwise it will speed up the scraper scrapped. When the individual bag small area damage occurs, you can use the old cloth bag or the same material new filter cloth to make up the use of holes, hole filling method is to use silicone rubber compound for bonding, as long as the adhesive temperature, chemical Performance and process conditions can be. When most of the bags are damaged, they should be replaced completely (when the filter is working for a long time, the fine dust accumulated in the filter layer will reduce its air permeability and affect the system air volume, but it should be replaced completely if it is not damaged) , Replace the bag is best to stop working when the precipitator, cleaning controller should be closed at this time, open the top of the manhole door, you can remove the bag, remove the bag cage first, and then the bag catchy Spring coil into a concave shape, pull out the bag up, install the new bag, the flower hole should be cleaned on the dust. Install the bag, dust skeleton method: the installation of cage and bag is the whole installation of the most careful and careful work, so should be placed at the end of the installation, installation, the bag must not be hit with the sharp objects, hooked even small Scratches, will also greatly shorten the life of the bag. The method of installing the bag is that the bag is put in the bag hole from the flower plate hole of the box first and then the spring ring in the upper part of the bag hole is pinched into a concave shape and put into the flower hole plate of the box body and then the spring ring is restored to make it Press tightly tightly around the circumference of the flower hole, and finally insert the bag cage gently from the pocket until the cover on the upper part of the cage does press against the flower hole in the box. In order to prevent trampled on the bag, each bag is required to install a bag cage. Such as replacement bag, the precipitator can not stop working, should be isolated off-line of each room, and then change the bag chamber compartment, the room should be isolated lift valve is closed, while the pulse valve does not work (to be safe, the Room pulse valve power off). When disassembling the bag, due to a small amount of negative pressure bag should be particularly careful not to drop the bag into the ash bucket.
