How to judge whether the filter bag has failed during use?

Determining whether a filter bag has failed requires observation and inspection of multiple factors. The main function of filter bags is to filter solid or liquid particles and prevent them from entering the air or liquid flow. Here are some common ways to tell if a filter bag has failed:

Observe the filtration effect: Check the outlet of the filtration system to see if there are any particles or dirt passing through. If a large amount of particulate matter or dirt is present, it may be a sign that the filter bag is failing.

Differential pressure monitoring: Monitor the pressure difference between the inlet and outlet of the filtration system. Over time, filter bags can accumulate particulate matter, causing the pressure differential to increase. If the pressure difference continues to increase to a certain level, it may indicate that the filter bag has failed or is about to fail.

Touch inspection: Carefully touch the outer surface of the filter bag with your hands to feel for any agglomerations, hardening or damage. If there is visible damage to the surface of the filter bag, it may have failed.

Check for leaks: Check for particulate or liquid leaks around the filtration system. Leaks may indicate a damaged filter bag or a poor seal.

Regular replacement: According to the material of the filter bag and the working environment, the replacement cycle is determined. Regular replacement of filter bags is an important measure to prevent failure.

Visual inspection: If the filter bag is visible, regularly inspect the surface of the filter bag for damage or blockage.

Check the filtration efficiency: Test equipment such as particle counters can be used to check the filtration efficiency of the filtration system to ensure that it meets the design requirements.

The filter bag manufacturer reminds you to pay attention: different types of filter bags may have different failure signs and judgment methods, so it is recommended to refer to the relevant operation manual and manufacturer's recommendations when using the filter system to ensure that the state of the filter bag is correctly judged. Regular maintenance and replacement of filter bags is essential to ensure the normal operation and effectiveness of the filtration system.
