In the tantalum-niobium wet extraction process, the extraction equipment is central, and its operating condition is crucial to production efficiency and product quality. To ensure long-term, stable operation, regular maintenance is essential to extend equipment life, reduce malfunctions, and ensure safety. The following are key points for routine maintenance of extraction equipment:

1. Inspection and Replacement of Sealing Components

Seals and rings in extraction equipment are crucial for leak prevention. Because the process involves corrosive substances, sealing materials are susceptible to aging and wear. Regular inspection of seal integrity is essential, and any leaks should be replaced immediately to minimize material loss, contamination, and safety hazards.

2. Lubrication of Agitation and Transmission Devices

The agitator and transmission components, such as bearings and gearboxes, require proper lubrication. Regular addition or replacement of high-performance lubricants reduces wear, prevents seizures, and overheating. A lubrication schedule based on equipment usage frequency is recommended.

3. Internal Cleaning

Extraction tower packing and stripping equipment separation components are prone to accumulation of impurities. Prolonged cleaning can lead to blockage, reduced efficiency, and even failure. Regular shutdown and cleaning are necessary, using chemical or mechanical methods to remove residues and inspecting and replacing damaged packing. 4. Electrical System Inspection and Calibration

Modern extraction equipment features automated electrical control systems. Regular inspection of sensors and controllers, system calibration, and cable connections are essential.

5. Corrosion and Wear Monitoring

The wet extraction environment is highly corrosive, and equipment is susceptible to corrosion and wear. Regularly monitor wall thickness using nondestructive testing techniques and preventively replace worn parts.

In short, regular maintenance of extraction equipment is essential for stable process operation. A detailed maintenance plan should be developed and strictly adhered to ensure optimal equipment condition and high-quality production.
