The maintenance and upkeep of fiberglass folding filter cartridges should be combined with material characteristics and usage scenarios. The specific methods are as follows:
1. Regular inspection and monitoring
Appearance inspection: Check if the filter element is damaged, deformed, or if fibers have fallen off. Special attention should be paid to the fiber integrity of the fiberglass material.
Differential pressure monitoring: The blockage situation is determined by the pressure difference between the inlet and outlet. If the pressure difference exceeds 0.1MPa, it needs to be cleaned or replaced.
2. Cleaning method
Backwash: supports reverse water or gas flow to remove surface impurities, suitable for mild pollution.
Chemical cleaning: In case of severe pollution, soak in neutral cleaning agent (avoiding strong acidity and alkalinity), and then rinse thoroughly with water.
Disinfection: Regularly disinfect with 75% alcohol or ozone water to prevent microbial growth.
3. Replacement cycle
Universal cycle: 3-6 months for replacement, shortened to 1-3 months for high load or harsh environments (high temperature, strong corrosion).
Material difference: Glass fiber filter element is resistant to high temperatures (below 90 ℃), but long-term high temperatures will accelerate aging and need to be replaced in advance.
4. System maintenance
Shell cleaning: Regularly clean the filter shell and pipeline to avoid secondary pollution.
Sealing inspection: Ensure that the sealing ring is not deformed or aged to prevent leakage.
5. Optimization of operating environment
Flow control: To avoid overload operation, it is recommended that the flow rate does not exceed 80% of the rated value.
Pre treated influent: Install a pre filter to reduce large particle impurities and extend the lifespan of the filter element.
6. Precautions
Wear protective equipment during operation to prevent fiberglass debris from coming into contact with the skin.
Record each maintenance time and filter status, and establish a replacement file.
The above methods can effectively extend the service life of fiberglass folding filter cartridges and ensure filtration efficiency.
