Q:How can you not damage the filter bag when the filter bag is installed?
The dust filter bag has a great effect on the dust removal effect, and the filter bag must not be damaged by the installation. 1 should pack the filter bags to the installation location and install one of them. The filter bag cannot be dragged carelessly on the board, to prevent the metal burrs from the surface of the filter bag, and damage the filter bag. Remove from the packing box until it is installed to the orifice of the flower plate, not touching any metal or surface roughness. Use the protective cover provided by the supplier when using the orifice, in case the filter is touching the plate hole.
Q:How do you clean a filter bag with oil stains?
Clear the dust filter bag with oil: using high frequency vibration, will enter the dust filter bag inside the wall of the larger dust particles removed, will not affect fiber entanglement of fastness, keep the filter bag is good, easy tear of dirt. Chemical experiment treatment: extract the bag samples, using the professional instrument laboratory detection filter filter bag oil composition, to adapt to washing raw materials, the maximum cleaning filter bag and without causing any damage to the filter bag.
Q:Problem with the washing machine filter bag
You see if the filter is blocked, or the hole in the inner drum is blocked
Q:What are the features and methods of using filter bags?
Self-flow open filtering: the filter bag is directly connected to the pipe by suitable connectors, and it is filtered by the differential pressure differential. It is characterized by the need not to invest in the equipment, the filter is simple and feasible, especially suitable for small specification, various kinds, intermittent type of economical liquid filtration
Q:Filtration efficiency of liquid filtration bag
Absolute filter: filter is absolutely intercept surface filtering method, is greater than a certain size particles of 95-99.9% were intercepted, less than the size of the particles by all. Pore size must be same size on the surface of the filter bag material, weave fabric must be tight and firm, material requirements after joint can bear high pressure, can prevent leakage occurs, absolute filtering effect can be assured.
Q:How does the filter bag work?
The automatic grey way of the filter is the high-pressure gas pulse and the mechanical vibration.
Q:How to choose a liquid filter bag
1, first of all, according to the chemical name to filter the fluid, according to the chemical with taboo to find available filter material, commonly used in PE, PP, PTFE, NMO, again according to its operating temperature, operating pressure, ph, operating conditions (such as whether to need to tolerate steam, hot water or chemical sterilization, etc.), assessed and eliminate shall not apply to the filter material. Use is also an important consideration, such as pharmaceutical, food or cosmetic ingredients that must be approved by the FDA; Ultra-pure water should be chosen for pure and not contain the filter material that will affect the impedance. Filter gases should be selected for hydrophobic materials and whether "health grade filtering" design is required. The main foreign Filter bags are GAF, FSI, 3M, CUNO, U.S. Filter, LOEFFLER, PARK, Vablue Filter bag etc
Q:In what aspects is it convenient to choose the filter bag?
First, it is important to understand the temperature of the smoke that is being processed. If the normal temperature of the filter is lower than the temperature of the flue gas, it is possible to cause the cloth bag to burn down and cause a large economic loss. So how do you select the filter by the smoke temperature? Filter material by using temperature is divided into: under normal temperature is below 130 ℃, the temperature filter material of 130 ~ 180 ℃, high temperature filter material of 180 ~ 280 ℃. It is known that the temperature of the flue gas and the temperature of the filter can be selected by the filter. The second step is to understand the composition of smoke: this includes the content of the dust, the proportion, the size of the particle size, the viscosity and the moisture content of the flue. The method of cleaning the dust dust, the method of reprocessing and the filter wind speed of the filter were obtained. Usually a large amount of dust and dust is sticky and light condition choose pulse bag filter, filtration speed most control over 1.2 m/min, the minority under 1 m/min. The third step is to understand the amount of smoke that needs to be processed: the amount of air that dust can be treated by the dust collector is usually the operating air volume and the system leakage coefficient (10% ~ 15%). The formula: S = Q / 60V gives the total filter area by the formula: S = Q / 60V. S: total filter area Q: system processing air volume V: filter wind speed.
Q:Who has used a liquid filter bag? What is its feature?
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:Why is the filter bag material PE a polyester, not a polyethylene
PE (Polyethylene) : Polyethylene, is the most simple structure of high polymer organic compounds, in today's world the most PE Polyethylene widely used polymer materials, composed of ethylene polymerization.
