Bag filter itself has a lot of advantages, such as a relatively new structure, small size, very simple operation, high filtration efficiency, low energy consumption, wide range of applications and strong applicability, and the filter bag replacement is also very convenient. A filter with so many advantages, if not properly used, or will affect the service life, so what to pay attention to in the process of using the bag filter?

When replacing the filter bag of the bag filter, we should pay attention to the way of replacing the bag filter bag, generally speaking, we will first close the water inlet valve, and then open the exhaust valve, so that the pressure inside the bag filter can be reduced to the normal pressure state. After that, we should open the bolt on the top cover, and then open the snap ring that fixes the filter bag, and pay attention to the correct way of operation, not violent disassembly. After disassembling the bag filter, take out the clogged filter bag, replace it with a new one, then fix the filter bag's snap ring, close the top cover, lock the top cover tightly, then open the inlet valve, wait until the exhaust valve has liquid flowing out, then you can close the exhaust valve. This operation process is very fast, basically the entire replacement of the filter bag time of less than 15 minutes.

When replacing the bag filter, it should be noted that when dismantling the bag filter, it is necessary to find a method and use reasonable tools to dismantle it, so as not to damage the bolts of the snap ring and the top cover, and avoid that the filter bag cannot be fixed well or the sealing of the bag filter is affected due to incorrect operation.

When bag filter to pay attention to these issues.

1. to check whether the link bag filter pipeline is strong enough, there is no leakage or damage phenomenon.

2. to check the bag filter pressure gauge to see if the value of the pressure is normal, to see these values during normal operation and shutdown of the machine, to see if the import and export valves are sealed enough and if the rate of pressure reduction is normal.

3. Bag filter should check whether the O-ring is deformed or scratched, whether there is damage to the phenomenon, if there is a similar phenomenon, it needs to be replaced in time. Of course, in reminding everyone, in the process of inspection must pay attention to safety, to avoid incorrect inspection methods lead to inspectors in the inspection process can not ensure personal safety.

When using the bag filter, whether it is the operation process, or the process of changing the filter bag, or in the inspection and maintenance, it is necessary to pay attention to the use of the correct way and process.
