[0002] Solenoid valves play a vital role in industrial automation control systems and are widely used in various mechanical equipment and production processes. To ensure their reliability in real-world applications, rigorous performance testing is required. Existing solenoid valve testing primarily focuses on static functional verification at room temperature. However, actual applications often involve extreme temperatures, high pressure, vibration, and other complex operating conditions, placing higher demands on solenoid valve performance.
[0003] Among the currently commonly used solenoid valve testing methods, the normal temperature test method mainly detects the basic performance indicators of the solenoid valve under room temperature conditions, but it cannot simulate the extreme temperature environment in actual applications; the simple temperature control test method simply changes the ambient temperature through a heating or cooling device for testing, but it is still difficult to fully simulate complex working conditions; the static hydraulic boost test applies constant pressure to the solenoid valve through an external hydraulic pump to detect its performance changes, but this method also fails to combine different temperatures for comprehensive evaluation.
[0004] The above-mentioned conventional testing methods in the existing technology are difficult to comprehensively evaluate the performance of the solenoid valve under different temperature environments and its stability under high hydraulic conditions. Especially when it is necessary to consider high and low temperature and high pressure factors at the same time, there is a lack of an effective integrated testing system to comprehensively test the reliability and durability of the solenoid valve.
