1. Not in Use: Immediate Replacement or Return
If the equipment is not yet installed or is in the acceptance phase, refuse to sign for it and require the supplier to replace it with a qualified product according to the contract and national standards (such as JB/T 9035-2015).
Require materials such as certificates and SGS test reports to ensure that the 304/316 stainless steel and wear-resistant nylon tubing meet the standards.
2. Installed but Not Operating: Partial Replacement of Key Components
Hydrocyclone Tube: If the main body is stainless steel but the inner lining is of inferior material, it can be replaced separately with high-wear-resistant nylon or polyurethane tubing to reduce overall losses.
Seals and Connections: Replace with corrosion-resistant fluororubber or silicone gaskets to prevent leakage due to material incompatibility.
3. In Operation: Emergency Handling and Temporary Protection
Add a Filtration System: Add a precision filter before the feed to reduce the scouring of the inferior inner wall by impurities and delay wear.
4. Reduce Operating Pressure: Reduce operating pressure from 0.8 MPa to below 0.5 MPa to lessen stress on vulnerable areas.
Shorten Operating Cycles: Implement a "short-time, high-frequency" operating mode, stopping the machine for inspection every 2 hours to promptly clear blockages and prevent sudden malfunctions.
5. Long-Term Countermeasures: Install anti-corrosion and wear-resistant coatings. For corroded or roughened inner walls, ceramic epoxy coatings or polyurethane spraying techniques can be used for surface repair, improving corrosion resistance and smoothness.
Some cases show that coating repair can extend equipment life by 1-2 years.
6. Monitoring and Early Warning Mechanism: Install online pressure sensors and leakage alarm devices to monitor operating status in real time.
Establish a daily inspection system, focusing on checking welds and cone connections for signs of leakage, discoloration, or deformation.
