As a leading manufacturer of non-standard testing equipment, Ziwei Testing offers a wide range of solutions for automotive and industrial applications. Today, we are pleased to introduce our: High-Temperature Clamp Bending Fatigue and Pressure Cycling Test Module.
This equipment is designed for bending load and pressure cycling tests of quick-release clamps used in high-temperature and high-pressure aviation air pipeline connections. The system is a three-variable coupled testing system integrating high-temperature gas, high-pressure alternating pressure, and bending load fatigue. The system operates fully automatically and can run unattended 24/7. The test specimen is installed in a high-strength protective chamber to ensure the safety of operators and surrounding laboratory equipment. The chamber is equipped with temperature monitoring to prevent danger caused by leakage of high-temperature compressed air. Combined with protection logic such as pressure control protection, over-temperature protection, and overload protection, it achieves automatic shutdown and alarm in abnormal situations.
The gas inside the test specimen is heated using a three-stage heating system, which effectively reduces temperature fluctuations during the pressure pulse process and extends the service life of the heater. At the same time, heat recovery is achieved in the first heating stage, reducing equipment energy consumption and lowering exhaust temperature. The bending load adopts electro-servo loading control technology to achieve bending load and pulse pressure output control according to a predetermined phase difference.
