DMHUI High Pressure Seal Performance Test: 30MPa Leak-Proof Verification

Test Dimensions:

• Pressure Test: The DMHUI high pressure seal was subjected to continuous operation under a pressure of 30MPa for 72 hours without any leakage. This rigorous test was conducted to validate the seal's leak-proof capabilities under extreme conditions. The results clearly demonstrate that the seal maintains its integrity under high pressure, far exceeding industry standards.

• Temperature Cycle Test: The seal was exposed to temperature cycling ranging from -40°C to 120°C (for nitrile seals) and -20°C to 200°C (for Viton seals). Throughout the testing period, the seals showed no degradation in sealing performance, demonstrating excellent resistance to extreme temperatures.

• Medium Immersion Test: The nitrile seal was immersed in mineral oil for 30 days, and its volume change was less than 5%. The Viton seal was exposed to strong acids for the same period with no swelling or degradation, proving that both materials offer exceptional resistance to harsh chemicals and operational environments.

Data Comparison:

In comparison with industry-standard high pressure seals, the DMHUI TCV seal performed at an exceptional level. For instance, the leakage rate of the DMHUI high pressure seal was measured at only 0.01ml/h, which is 10 times lower than the industry average of 0.1ml/h. This significant reduction in leakage rates highlights the superior performance and reliability of DMHUI's high pressure seal in challenging environments.

Additional Observations:

• The seal's exceptional durability in both high-pressure and high-temperature environments ensures that it performs reliably for extended periods, reducing the need for frequent maintenance and replacement.

• DMHUI’s high pressure seal offers a high level of leak-proof performance, even when exposed to aggressive chemicals and extreme environmental conditions.

• The test results validate that DMHUI’s high pressure seal is among the best in the industry, making it the optimal choice for various industrial applications requiring reliable, long-lasting sealing solutions.
