The life testing machine for liquid cooled fluid connectors (quick connect fittings) is developed and manufactured according to specifications such as CQC/PV 21009-2025, GB/T5816-2003/ISO7241-2:200, and customer customized testing requirements. It can simulate the service environment of high and low temperature ethylene glycol coolant under actual working conditions and conduct pressure pulse durability tests on the samples.

The equipment is composed of four core modules: medium circulation system, electro-hydraulic servo pulse drive system, computer measurement and control system, and high and low temperature liquid constant temperature control device. The whole machine selects high-quality electrical and hydraulic drive components, combined with mature and advanced computer measurement and control technology, and can customize differentiated testing plans according to the working parameters of different specifications of joints and pipeline products, flexibly matching various testing scenarios.

The equipment is mainly used for fatigue life testing of liquid cooled quick connect fittings, water delivery fittings, pressure resistant hoses and other components, to verify the structural stability and sealing reliability of the product under long-term pressure and temperature cycling. The equipment operation interface is simple and intuitive, the overall operating conditions are stable and reliable, the failure rate is low, and the equipment manufacturing cost is reasonable, with outstanding cost-effectiveness in comprehensive use.

The equipment has the ability to customize and adjust parameters, and can set core test parameters such as pulse pressure amplitude, pulse frequency, cycle number, medium constant temperature range, and holding time as needed, to meet the testing needs of multiple types of samples. The measurement and control system collects key data such as pressure, temperature, and cycle times in real-time, and presents the experimental status dynamically and visually throughout the process.

Equipped with a complete safety protection mechanism, it is equipped with pressure overload protection, over temperature protection, pipeline pressure relief protection, emergency stop interlock function, and automatic shutdown warning in case of abnormal testing, effectively avoiding problems such as sample damage and equipment failure. The experimental data can be automatically stored and archived, supporting report generation and data export, facilitating the traceability of experiments, quality judgment, and the issuance of testing reports.

The integrated layout of each system module is compact and orderly, with excellent pipeline sealing performance, which can prevent coolant leakage problems; The equipment has strong fatigue resistance and can conduct durability testing continuously for a long time without interruption. It is easy to debug and maintain, and can stably meet various testing requirements such as laboratory batch testing, product type inspection, and factory sampling.
