DMHUI High Pressure Seal Maintenance: Extend Service Life in Extreme Conditions

Key Maintenance Issues:

• Seal Degradation: Exposure to high pressure and extreme temperatures can lead to seal wear and eventual leakage. Solution: Regular inspection and maintenance are critical. Switch to DMHUI’s Viton TCV high pressure seals for extended durability and resistance to high-pressure environments.

• Contaminant Build-Up: Contaminants on the shaft or in the hydraulic fluid can lead to poor sealing performance. Solution: Regularly clean the shaft surface and ensure that hydraulic fluid is properly filtered. Consider adding a guide sleeve during installation to prevent debris buildup.

• Incorrect Shaft Surface Finish: A rough shaft surface (Ra > 0.8μm) can cause seals to wear prematurely. Solution: Polish the shaft surface and use DMHUI’s thick-lipped TCV seal to ensure better contact and sealing.

Extended Service Life Tips:

• Choose the right seal material based on the operational environment (e.g., Viton for high-temperature and chemical resistance).

• Perform regular maintenance checks to identify early signs of wear, such as minor leaks or abnormal noise.

• Replace seals at regular intervals as part of a preventive maintenance schedule to reduce the risk of failure.
