Jam. The main reasons for the failure of bag filter bag are: The oil is in a jam. Oil mist blockage mainly boiler start-up and low load operation for oil fuel, not the filter bag protection or protection does not reach the designated position, this will lead to the residual resistance increase of filter bag, even the powerful soot cleaning is difficult to solve this problem. Dust jam. In the process of filter bag dust collector of fine dust can enter into layers of filter bag, but when the ash removal is not possible to these all back into the inside of the filter bag dust filter bag outside, so after years of running the residual resistance of filter bag will continue to increase, in addition low boiler load for a long time when the filter is not clear ash can also lead to the emergence of the problem.

It is. Finally, there is a kind of liquid filter bag, the filter bag is used in the welding technology of stainless steel, greatly reduces the probability of filter bag sliding sideways, this technique can well improve the sealing of filter bag, reduce error, seal degree is high
Q:What is the advantage of the oil filter bag?
In addition to oil filtering bags: Multi-layer melt polypropylene filtration material, which helps to filter liquid level by stage
Q:How is the filter bag type and filtration efficiency
Viscose particles in the more, especially the more big particles (diameter greater than 15 1 xm) and spinnability of spinning and viscose fiber the greater is the impact on the quality of the finished product, these impurities cause increased congestion, breakage, spinneret spinning when produce plastic blocks and hair silk, causing changes in the size.
Q:Is there a filter bag for the washer?
A cylinder washer is not a filter bag. And there's no drain valve, but he has a pump. So where did the dirt go? You can look at the structure of the drainage pump first.In fact, he is a vane pump, so the dirt not sensitive, general MAO flocculant, can be directly into the sewer, there is no need to filter bag, larger smudgy, can open the cover to remove. The experience I've been using for a decade or so is that there is no such thing at all
