DMHUI High Pressure Seal Fatigue Resistance Test: Leak-Proof Performance Under Repeated Stress

Test Dimensions:

• Fatigue Resistance Test: The DMHUI high pressure seal underwent a rigorous fatigue resistance test where it was exposed to repeated pressure cycles (30MPa) for 1000 cycles. The seal showed no signs of leakage or degradation, demonstrating its exceptional durability and resistance to fatigue.
• Pressure Resistance Test: The seal was subjected to a continuous pressure of 30MPa for 72 hours without leakage. This proves that the seal is reliable even under sustained high-pressure environments.
• Temperature Resistance Test: The seal was tested in extreme temperatures ranging from -40°C to 120°C for nitrile seals, and from -20°C to 200°C for Viton seals. The seals showed no signs of performance degradation even under fluctuating temperature conditions.

Data Comparison:

DMHUI’s high pressure seal performed exceptionally well compared to industry standards. The leakage rate of DMHUI’s seal was recorded at 0.01ml/h, which is ten times lower than the typical leakage rate of 0.1ml/h seen in competitor seals.

Additional Observations:

• DMHUI seals exhibit superior performance in both fatigue resistance and high-pressure resistance, ensuring that they provide reliable and long-lasting sealing solutions in demanding industrial applications.
• The seals’ resistance to temperature and chemical fluctuations contributes to their reliability, even in extreme conditions.
• By reducing leakage and extending the service life of the seals, DMHUI products significantly reduce maintenance costs and improve system reliability.

Conclusion:

The results of the fatigue resistance test, combined with the other high-pressure and temperature tests, prove that DMHUI high pressure seals offer outstanding leak-proof performance, even under the most extreme conditions. The durability and performance of these seals make them an ideal solution for industries requiring reliable sealing solutions for high-pressure applications.
