Hydraulic valve test bench

Hydraulic valve test bench

The hydraulic valve test bench is a device specifically designed to test and evaluate the performance of hydraulic valves. Its main function is to simulate the working environment of hydraulic systems and ensure their reliability and stability in practical applications by testing hydraulic valves under various working conditions. Hydraulic valves play a crucial role in industrial automation, mechanical manufacturing, and automotive fields, making accurate performance evaluation particularly important. The test bench is usually equipped with various measuring devices such as pressure sensors, flow meters, and temperature sensors to monitor the working status of hydraulic valves in real time. Through these tests, engineers can obtain key parameters such as flow characteristics, pressure loss, and response time of hydraulic valves, providing a basis for subsequent design improvements and quality control. Our test bench is well-designed, easy to operate, and suitable for testing various hydraulic equipment.

Core advantages and characteristics：

1. High testing accuracy and reliable data

Equipped with high-precision sensors, the pressure accuracy can reach ± 0.5% FS, and the flow accuracy can be ± 1% FS.

The system has minimal pressure fluctuations and can accurately simulate actual working conditions, ensuring accurate and highly repetitive test data.

Support multi-dimensional testing of dynamic (response time, overshoot) and static (pressure regulation characteristics, flow characteristics).

2. High degree of automation, efficient and energy-saving

Adopting PLC+touch screen control, automatic loading, voltage regulation, current regulation, and one click completion of testing.

Automatic clamping and data recording, efficiency improved by over 50%, reducing human error.

Electric proportional stepless pressure/flow regulation, on-demand energy supply, low energy consumption, and stable loading.

3. Comprehensive safety protection, stable and durable

Multiple protections including overpressure, overheating, overload, and emergency shutdown ensure the safety of equipment and personnel.

The key components are imported or first tier brands with a lifespan of over 15 years and a failure rate of less than 2%.

Closed structure+residual oil recovery, clean and environmentally friendly, easy to maintain.

4. Comprehensive functionality and strong compatibility

Almost all hydraulic valves can be measured, including overflow valves, pressure reducing valves, directional valves, multi way valves, proportional/servo valves, etc.

Complete testing items: pressure resistance, pressure regulation range, internal leakage, pressure loss, steady-state/dynamic response, etc.

Supports USB/Ethernet data transmission, automatically generates curves and reports for easy traceability and analysis.

Main application areas：

1. Manufacturing of hydraulic components (factory quality inspection)

Conduct 100% factory inspection on multi way valves, balance valves, overflow valves, etc. to ensure compliance with JB/T, GB and other standards.

Typical scenarios: valve body leakage, pressure regulation accuracy, directional performance, flow characteristic testing.

2. Host and construction machinery manufacturing

Hydraulic valves for excavators, loaders, cranes, and other equipment undergo factory calibration and pre assembly testing.

Verify the compatibility of valve components to avoid complete machine shutdown or safety accidents caused by valve failures.

3. Research and testing institutions (R&D/certification)

Universities and laboratories are used for valve performance research, new product development, aging/life testing.

Third party testing institutions provide type testing, certification testing, and arbitration appraisal services.

4. Maintenance and Remanufacturing (Fault Diagnosis)

Perform performance recovery testing on the repaired hydraulic valve to determine if it meets the original factory standards.

Quickly locate faults such as internal leakage, jamming, and slow response to improve maintenance quality and efficiency.

5. Aerospace, military, and new energy

Aerospace: Dynamic response and high-pressure sealing testing of high-precision servo valves and proportional valves.

Military industry: Verification of hydraulic system reliability and environmental adaptability (high and low temperature, vibration).

New energy: Leakage and flow control accuracy testing of energy storage liquid cooling systems and wind turbine hydraulic valves.
