Q:What is the line on the top of the filter bag?
Twill is good for wear-resisting and dust removal, but it is softer and less elastic than the satin weave, which is the most used in machine weaving
Q:What about the filtering effect of the lubricating oil filter bag
Lubricating oil filter bag is used on all types of machinery to reduce friction, protection machinery and mechanical parts of the liquid lubricant, mainly for lubrication, cooling, antirust, clean, sealed and buffer, and so on.
Q:What are the benefits of using a filter bag
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:How can the filter bag be processed later?
Dust filter bags can be processed according to specific requirements. Yiqing ash treatment Adopts the patent technology production Yi Qing ash density and breathable, needled felt filter material itself has a good soot cleaning performance, and can work long hours under high filtration velocity. Antistatic processing In certain concentrations, some dust occurs when a spark burns or is generated by friction. Therefore, it is suitable for inflammable and explosive dust to be used in the needle felt filter. Antistatic filter is used to describe the mixing of the filter fibers The conductive fibre (including the dual conductive fibre, graphite-conductive fibre and stainless steel conductive fibre) enables the whole filter to conduct electrical conductivity
Q:How to check the filter bag and the dust collector bag when the dust collector is installed?
You say the bag and the bag cage visual inspection before installation needs, from experience observation, at the time of assembly is the detailed inspection, in principle, a bag and bag cage on the diameter is 2.5 mm clearance, need adjustment of clearance is too large. Be careful when you wear a cloth bag. Are you asking about this question, the bag leak check, The method is to apply fluorescent powder to the surface of the phosphor powder, and see if there is any leakage at run time.
Q:What materials are commonly used in liquid filtration bags?
Chemical etch is good, acid and alkali resistance. The filtration efficiency is high, can reach more than 99.5% Expanding filter cloth (bag), improving filter wind speed and filtration efficiency, reducing the volume of dust removal equipment
Q:What is the filter principle of the high performance filter bag?
Mesh structure load the particles block on the surface of filter bag, can reduce the impact of the dust particles on the filter bag and make it easier to blow, prolong the service life of filter bag.
Q:In what aspects is it convenient to choose the filter bag?
The fabric design of dust filter bag should be designed to be efficient filtration, easy dust stripping and durable effect. Dust filter bag is one of the important parts in the precipitator, bag filter is generally according to the properties of dust, dust removal by way of the nature and filter according to the different filter filter bag, filter bag so select filter attention focus is also different. A filter bag that is suitable for price performance according to the requirement of operating condition. The gas temperature. Gas temperature below 130 ℃ selection filter filter bag at room temperature, the temperature between 130 ℃ to 260 ℃ high temperature dust filter bag. Gas humidity. Dusty gases according to the relative humidity is divided into three states: dry gas (relative humidity below 30%), the general condition (relative humidity between 30% - 80%) and high humidity (relative humidity above 80%) of gas. When the gas moisture is high, you should choose the laminated waterproof cloth bag. The chemical properties of gases. The chemical elements of acid, alkali, oxidizing agent and organic solvents are found in all kinds of furnace gases and chemical exhaust gases. In order to select the filter bag, the filter bag should be chosen according to the chemical composition in the flue gas.
Q:What is the filter bag for the washing machine?
Filtration of all kinds of fine dust that fall on clothing during the laundry process: hair, thread, paper, and other impurities Washing sheets and bedding are the most obvious, and there's a lot of hair that's been collected and useful. Always clean up and don't cause germs.
Q:What is the cause of the liquid filter bag
Filter bag itself problem: workmanship problem, filter bag currently do manual work is divided into hot melt welding and line sewing, hot melt welding stress is about 10 kg, and at the bottom of the triangle than arc pressure, seam about 16 kilograms to work under pressure, but if the jump line or off line easy to bag, pressure loss of the filter bag at run time will increase, the impurity scale, very test of the filter bag material and workmanship.
