DMHUI High Pressure Seal Performance Verification Test: Leak-Proof Results under Continuous Operation

Test Dimensions:

• Continuous Operation Test: The DMHUI high pressure seal was subjected to 1000 continuous hours of operation at a pressure of 30MPa. During this period, the seal showed no signs of degradation or leakage, demonstrating its long-lasting leak-proof performance in continuous high-pressure environments.
• Temperature Cycle Test: The seals were exposed to extreme temperature cycling, with nitrile seals tested from -40°C to 120°C, and Viton seals subjected to temperatures ranging from -20°C to 200°C. Both seal types maintained their sealing performance throughout the test, proving their exceptional thermal stability.
• Chemical Exposure Test: The nitrile seals were immersed in mineral oil for 30 days, with less than a 5% volume change. The Viton seals were exposed to harsh acids, showing no degradation or swelling, confirming their superior chemical resistance.

Data Comparison:

DMHUI high pressure seals outperformed the industry standard in all tested parameters. For instance, the leakage rate of the DMHUI TCV seal was recorded at 0.01ml/h, significantly lower than the industry average of 0.1ml/h, showcasing the superior sealing capability of DMHUI products under extreme conditions.

Additional Observations:

• DMHUI seals demonstrated exceptional performance during both continuous operation and extreme temperature exposure, making them ideal for high-pressure applications in demanding industries.
• The seals’ resistance to chemical exposure further enhances their reliability, providing a long-lasting, cost-effective solution in chemical and industrial environments.
• The low leakage rate and extended service life of DMHUI seals contribute to significant cost savings in maintenance and replacements.

Conclusion:

The DMHUI high pressure seal consistently demonstrates outstanding performance in high-pressure, high-temperature, and chemical environments. These tests validate that DMHUI’s seals offer exceptional leak-proof capabilities and durability, ensuring reliable performance in the most challenging industrial applications.
