The vacuum pump durability testing machine is a high-end detection device specifically designed to evaluate the reliability of vacuum pumps (such as rotary vane pumps, screw pumps, dry pumps, and Roots pumps) under extreme continuous operation conditions. By simulating harsh working conditions such as high and low temperatures, high-frequency start-stop, overload pressure, and dusty/corrosive environments, it comprehensively tests the mechanical durability, sealing stability, and performance degradation trends of vacuum pumps. It is widely used in semiconductor manufacturing, medical equipment, aerospace, industrial vacuum systems, and other fields, providing precise data support for product research and development improvements, quality certification, and after-sales maintenance.
Core functional modules
1) It can set the pumping pressure, automatically release the gas to the designated pressure when the set pressure is reached, and conduct cyclic tests.
2) It can control the pump's operation by time, for example: work for 4.8 seconds and stop for 1 second, and conduct cyclic tests.
3) It can be controlled by both time and pressure, for instance: work for 4.8 seconds, check if the vacuum degree reaches the set value of -70KPa, stop for 1 second and release the pressure to -50KPa, then the pump starts working again, and conduct cyclic tests. During the working cycle, it can monitor the current and vacuum degree (if the current exceeds the set value, it will alarm and stop the machine), record the cycle count and cumulative working time, and has the function of saving data when power is off. One device can run two vacuum pumps at a time.
Full-scenario condition simulation
Extreme environment testing: Supports temperature range from -40℃ to 150℃ and humidity from 10% to 98% RH (optional salt spray/dust simulation module), to verify the stability of vacuum pumps in harsh environments.
Dynamic load testing: Simulates pressure fluctuations (0.1Pa to 100kPa) and sudden changes in pumping speed (±30% instantaneous change) in actual working conditions, to test the pump's anti-shock capability.
Accelerated life testing
High-frequency start-stop cycle: Supports up to 500 start-stop operations per hour, accelerating the wear test of the motor and valves, and shortening the test cycle to 1/5.
Overload durability test: Can set an overload (120% to 150%) for continuous operation to test the ultimate lifespan of the pump.
Intelligent monitoring and diagnosis
Real-time multi-parameter collection: Simultaneously monitor vacuum degree, current, vibration, temperature, noise, etc., and dynamically generate performance degradation curves.
Fault warning system: AI algorithm automatically identifies abnormal data (such as abnormal bearing noise, seal leakage), locates the faulty component and generates maintenance suggestions.
Data management
Supports one-click export of test reports (PDF/Excel), cloud storage of data and remote monitoring (4G/WiFi), and is compatible with industrial Internet of Things (IIoT) platforms.
