Product Description
SSCH22-15000-30000 22kW Hydraulic Transmission System Dynamometer Test Bench
Product Description
The SSCH22-15000-30000 hydraulic transmission system dynamometer test bench is designed specifically for the aviation and high-end hydraulics industries. It integrates a high-speed aviation hydraulic pump, a 22kW high-speed electric dynamometer, a multi-mode load module, and an intelligent measurement and control system. It enables comprehensive performance testing of hydraulic components under high-pressure (35MPa), high-speed (30,000r/min), and variable-load conditions. The system supports bidirectional energy transfer (electrical dynamometer power return efficiency >85%) and, when combined with a remote control module, enables unmanned testing. It covers performance calibration, durability verification, and fault simulation of hydraulic pumps, actuators, and other components, meeting the high-precision testing needs of the aviation and high-end industrial hydraulics industries.
Dynamometer Components
SSCH22-15000-30000 22kW Hydraulic Transmission System Dynamometer Test Bench Components
1) High-speed aviation hydraulic pump: Rated pressure 35MPa, flow rate 20L/min, adapted to aviation-grade hydraulic media, with high-pressure stability, can simulate the core power source working conditions of the aircraft hydraulic system, and provide a continuous high-pressure oil source for the load module;
2) Fuel tank module: Available volume 70L, boost adjustment range 0-0.5MPa, negative pressure adjustment range -0.1-0MPa, can accurately control the oil pressure environment, avoid oil cavitation, and ensure oil cleanliness and stability under high-pressure conditions;
3) 22kW electric dynamometer: The core power test unit, capable of stepless speed regulation from 0-30,000 rpm, supports 150% overload operation, precisely controls torque through electromagnetic loading, and simultaneously recovers test power back to the grid.
4) Torque and speed sensor: Torque range 50Nm, speed range 30,000r/min, accuracy level ≤0.1% FS, real-time acquisition of hydraulic pump/motor torque and speed data, providing a highly reliable data source for performance calculations;
5) Variable frequency inverter system: Adopts direct torque control (DTC) with a control accuracy of ±0.01Hz; operating temperature range is 0°C to 40°C, protection level is IP54, and it can operate at full load at altitudes below 1000m with a noise level of ≤80dB, ensuring stable operation in harsh industrial environments;
6) Load module: There are two types of loads: Flow load: Regulates oil flow through throttle and relief valves to test the flow-pressure characteristics of the hydraulic pump; Linear load: Uses hydraulic actuators to simulate aircraft control surface load characteristics to verify the response performance of hydraulic components under reciprocating variable loads;
7) Measurement and control module: Integrates a multi-channel data acquisition unit (sampling frequency 500Hz), supports simultaneous acquisition of 120+ parameters including torque, pressure, flow, temperature, etc., and automatically generates performance curves (such as pump efficiency maps) and test reports;
8) Remote control module: adopts DSP+FPGA dual-core architecture, equipped with X86 architecture CPU (main frequency 750MHz, memory 512MB, DOM disk 4GB), pre-installed Win10 operating system, supports LAN/cloud remote control of test process and data viewing, and realizes unattended testing.

Technical Advantages
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.
4) Remote intelligent control: The DSP+FPGA architecture remote control module supports Windows 10 system operation, enabling remote start-stop testing and data retrieval within 100km. Combined with the automatic report generation function, testing efficiency is improved by 30%;
5) Multifunctional load coverage: Dual-mode design of flow load (throttle valve/relief valve) and linear load (actuator) can simultaneously complete the hydraulic pump "static performance calibration" and "dynamic load response" testing without changing the bench equipment;
6) High reliability and environmental adaptability: The variable frequency inverter system has an IP54 protection level and a -0.1-0.5MPa fuel tank pressure adjustment, making it suitable for multiple scenarios such as laboratories and aviation parts factories, and can operate stably in low temperature (0°C) and dusty environments.
