Why Is Some Dust Filter Bag Especially Easy To Damage

Why is some dust filter bag especially easy to damage
The dust bag is a kind of efficient dust filter material, which is usually made of polyester staple or long fiber. Its service life is usually four to six times that of glass fiber fabric. It has good ventilation performance, high dust removal efficiency, and certain acid, alkali and heat resistance. The dust removal rate can reach 99.999%.
1. Use temperature
The key of filter bag is to select the dust bag suitable for the corresponding dust temperature. If the temperature is too high, the selected dust bag to exceed the normal use temperature, dust filter bag manufacturer filter bag light will shorten the service life, serious will be burned in a short time. Therefore, when selecting filter bag, we must measure and calculate the inlet temperature of dust collector, and select the corresponding dust bag.
2, filter the wind speed
The high filter wind speed of the bag dust collector is the main reason for the damage of the bag. In recent years, some units blindly reduce the cost of equipment, increase profits, in the design of bag dust collector, the filter wind speed is increased, the user has no obvious reaction in a short time, but greatly shorten the service life of the filter bag.
3. Product quality
In recent years, some small manufacturers use small sewing machines as processing equipment, and processing with inferior line as raw material, false and true, processing level is far behind. So that the dust bag in the use of time is not long, the phenomenon of opening, cracking, falling off the bottom. Although the cloth bag size is slightly smaller, it can also be used, but after adsorption of dust with a larger proportion, it will appear to drop the bag phenomenon after a period of use.
The filter bag is the heart of the cloth bag dust collector in the process of operation. Usually, the cylinder type pulse filter bag is suspended vertically in the dust collector. The dust containing gas enters the dust collector through the air inlet and passes through the guide plate of the dust hopper, so that part of the large particle dust in the gas is separated by the action of inertia force and directly falls into the dust hopper. The dusty gas enters the filter bag filter area of the box body, and most of the dust is captured on the outer surface of the filter bag, while the clean gas enters the filter bag through the filter material, and the purified gas enters the upper box through the filter bag mouth, and then is discharged by the outlet. The cage rack inside the filter bag is used to support the filter bag and prevent the collapse of the filter bag. At the same time, it helps to remove and redistribute the dust cake.
