Highlight has successfully completed the supply and delivery of a customized Liquid Test Fatigue Test Bench for the China National Institute of Metrology (NIM). The project represents another milestone in Highlight’s development of high-precision pressure testing equipment and customized fatigue testing solutions for professional research institutions and industrial customers.

Designed for repeated pressure loading and durability evaluation, the delivered liquid fatigue test bench provides reliable testing capabilities for pressure-bearing components, hydraulic systems, and precision testing applications.

By integrating liquid pressure control technology, automatic cycle testing, high-accuracy measurement, and intelligent data acquisition, the system helps users evaluate product performance under long-term cyclic pressure conditions.

Project Background: Supporting High-Precision Fatigue Testing Requirements

The China National Institute of Metrology is a professional organization responsible for national measurement standards, calibration technology research, and advanced testing evaluation.

For research institutions and testing laboratories, traditional static pressure tests cannot fully evaluate the long-term reliability of pressure components. Many products experience continuous pressure fluctuations during actual operation, making fatigue performance testing essential.

The customized Flüssigkeitstest Ermüdungsprüfstand supplied by Highlight was developed to meet these requirements by providing:

• Repeated pressure cycle testing
• Stable liquid pressure control
• High-precision measurement
• Automated test operation
• Long-term fatigue evaluation

This system enables users to analyze how components perform under repeated pressure loading and verify their durability before practical application.

What Is a Liquid Test Fatigue Test Bench?

A Liquid Test Fatigue Test Bench is specialized equipment designed to perform fatigue testing using liquid as the pressure transmission medium.

During testing, the system repeatedly applies and releases pressure according to preset parameters, simulating real operating conditions.

Typical test parameters include:

• Maximaler Druck
• Minimum pressure
• Pressure cycle frequency
• Holding time
• Number of cycles
• Pressure waveform

Compared with conventional pressure testing equipment, a fatigue test bench focuses not only on whether a component can withstand pressure, but also on how long it can maintain stable performance during repeated operation.

Why Choose Liquid Pressure Fatigue Testing?

Liquid-based fatigue testing is widely used because liquids provide stable pressure transmission characteristics.

Compared with pneumatic fatigue testing, liquid testing offers:

Lower Stored Energy

Because liquids are nearly incompressible, the stored energy during pressurization is much lower than compressed gas systems.

This provides:

• Improved testing safety
• Better pressure stability
• More controlled failure analysis

Higher Measurement Accuracy

Liquid pressure systems allow precise monitoring of:

• Pressure changes
• Leakage conditions
• Pressure holding performance
• Fatigue behavior

Suitable for Long-Term Cycling

The system can perform continuous pressure cycles required for:

• Durability verification
• Life testing
• Reliability analysis
