1、 Appearance inspection

Regular inspection: Regularly inspect the appearance of the filter to ensure that there is no damage or corrosion on the surface of the equipment. The integrity of the casing is the foundation for the normal operation of the filter.

2、 Sealing inspection

Interface inspection: Check the sealing of each interface of the filter to ensure that there is no leakage or air leakage. If the sealing components are aged or damaged, they should be replaced in a timely manner to ensure the tightness of the system.

3、 Replacement cycle

Reasonable formulation: Based on actual usage and the characteristics of the filter medium, establish a reasonable replacement cycle for the filter bag. In general, when the pressure drop of the filter increases significantly, replacement of the filter bag should be considered.

4、 Cleaning and drying

Cleaning the filter bag: In some cases, the filter bag can be cleaned and reused. Appropriate cleaning agents should be used during cleaning to avoid damage to the filter bag material. After cleaning, the filter bag should be thoroughly dried before reinstalling for use.

Cleaning agent selection: When cleaning, choose the appropriate cleaning agent based on the material of the filter and the properties of the filter medium, avoiding the use of highly corrosive or damaging cleaning agents to the filter bag material.

5、 Correct installation

Installation steps: After replacing or cleaning the filter bag, ensure that it is installed correctly. The filter bag should be fully unfolded and tightly attached to the filter housing to avoid a decrease in filtration efficiency due to improper installation.

6、 Environmental control

Suitable temperature: The filter should operate at a suitable ambient temperature. Excessively high or low temperatures can affect filtration efficiency and equipment lifespan. Ensure that the operating environment temperature is within the allowable range of the filter design.

Above, the maintenance and upkeep of bag filters involve multiple aspects, including visual inspection, sealing inspection, establishment of replacement cycles, cleaning and drying, correct installation, environmental control, media pretreatment, pressure monitoring and adjustment, establishment of maintenance records, regular evaluation, and reserve of spare filter bags. Through these measures, the service life of the filter can be effectively extended, ensuring its stable and reliable operation.
