The maintenance methods for stainless steel titanium rod filters involve daily cleaning, regular inspections, and handling of special working conditions. The specific operations are as follows:
1、 Daily maintenance
1. Cleaning and rust prevention
Immediately soak and soften stains with clean water or weakly acidic cleaning agents after use to avoid scratching the surface with hard objects. Brush gently along the direction of the filter mesh texture. When used in a humid environment for a long time, it is necessary to dry off the moisture and apply anti rust oil to prevent oxidation.
2. Sealing inspection
Regularly check whether the flange cover, bolts and other connection parts are loose, whether the sealing ring is aging, and replace the faulty parts in a timely manner. During installation, tighten the bolts diagonally to ensure even force distribution.
2、 Regular in-depth maintenance
1. Filter element treatment
Check the blockage of the filter element every 1-3 months. If the pressure difference significantly increases, backwash or replace the filter element. When disassembling, the valve should be closed and the pressure should be released to avoid splashing of the medium.
2. Special maintenance of titanium rod
Titanium rod filter element is a consumable part and cannot be reused. If deformation or damage is found, it needs to be replaced immediately, otherwise it will affect the filtration accuracy.
3、 Response to special working conditions
1. Corrosive medium
When filtering strong acid/alkali media, the cleaning cycle should be shortened to once a week and the corrosion of the shell should be checked. When shutting down, it is necessary to drain the residual medium to prevent crystallization corrosion.
2. Long term discontinuation
After cleaning and drying, place desiccants inside, wrap them with dust covers outside, and store them in a ventilated and dark environment.
4、 Safety operation standards
1. Before maintenance, it is necessary to cut off the power or close the valve to ensure that there is no pressure residue in the system.
2. It is prohibited to dismantle core components without authorization. Filter replacement or electrical faults must be operated by professional personnel.
The above measures can effectively extend the lifespan of the equipment and maintain stable filtering performance.
