5. SSCH22-15000-30000 22kW Hydraulic Transmission System Dynamometer Test Bench Core Advantages

1) High-speed, high-precision testing capabilities: The electric dynamometer has a maximum speed of 30,000 r/min and is equipped with a torque sensor with an accuracy of ±0.1% FS. This allows it to capture transient performance fluctuations of aircraft hydraulic pumps at high speeds, meeting the "high-speed, low-error" testing requirements of high-end hydraulic components.

 

2) Deeply adapted for aviation scenarios: The linear load module simulates aircraft control surface load characteristics through hydraulic actuators. Combined with a 35MPa high-pressure aviation hydraulic pump, it can replicate the actual operating conditions of aviation hydraulic systems, providing a realistic testing environment for the development of aviation hydraulic components.

 

3) Energy recovery and energy saving: The electric dynamometer achieves over 85% power retransmission, reducing annual energy consumption by over 40% compared to traditional resistive load test benches. It is particularly suitable for long-term endurance testing of hydraulic pumps for over 500 hours, significantly reducing operating costs.
