The maintenance and upkeep of the bag filter pulse valve is the key to ensuring its long-term stable operation.

1. Regular inspection and cleaning

As the core component of the dust collector, the performance of the pulse valve directly affects the dust cleaning effect. According to multiple documents, regularly checking whether the pulse valve operates flexibly and without any jamming, cleaning internal impurities and moisture, and ensuring sealing performance are the key points of maintenance. For instance, it is mentioned that if the pulse solenoid valve malfunctions, internal impurities and moisture should be removed in a timely manner, and the diaphragm should be replaced promptly if it is damaged.

2. Diaphragm and sealing maintenance

The diaphragm of the pulse valve is a vulnerable part. Its damage will lead to a decline in the ash cleaning effect. It was all pointed out that when the diaphragm is damaged, it should be replaced in time to prevent air leakage or seal failure. In addition, regularly check the sealing performance of the cylinder and flange surface. If air leakage or aging of the sealing strip is found, replace it in time.

3. Maintenance of air sources and compressed air systems

The cleanliness and dryness of the air source system are crucial for the normal operation of the pulse valve. It is mentioned that the oil-water separator and oil mist lubricator should be cleaned regularly to ensure that the compressed air is dry and free of impurities, preventing moisture and oil from mixing into the gas path, and avoiding filter bag clogging and pulse valve failure.

4. Regular inspection and adjustment

Regularly check whether the operation of the pulse valve is normal and whether the injection pressure and cleaning cycle need to be adjusted. It is recommended to regularly measure process parameters (such as flue gas volume, concentration, and temperature), and adjust the operating parameters according to changes in operating resistance to ensure the efficient operation of the equipment.

5. Emergency response and troubleshooting

If any abnormality of the pulse valve is detected during the operation of the equipment, the machine should be stopped immediately for inspection to identify the cause of the fault. It is mentioned that if the diaphragm is damaged or blocked by internal impurities, it should be replaced or cleaned in time to avoid equipment damage.

6. Operating norms and safety

During the maintenance process, strictly follow the operation norms, such as cutting off the power supply and gas source, and ensuring that the equipment is shut down before conducting maintenance. At the same time, regularly check the sealing performance of the equipment to prevent dust leakage and the risk of dust explosion.

Summary

The maintenance and upkeep of pulse valves should be combined with regular inspections, cleaning, adjustments and emergency handling to ensure their long-term stable operation. Through scientific maintenance strategies, the service life of equipment can be prolonged, the dust removal efficiency can be improved, and production safety can be ensured.
