2. Features and Cooling of Hydraulic Station
1) The hydraulic station employs key components such as the Japanese NACHI internal gear high-pressure pump, an Italian Atos servo valve, and American-imported hydraulic components for the pressure-responsive valve, all aimed at enhancing the stability and long-term reliability of the hydraulic system.
2) This oil source utilizes the latest pressure-responsive technology, where the system pressure increases synchronously with the load. This allows the system pressure to avoid maintaining a constant high pressure for extended periods, which would generate excessive heat. This technology makes the hydraulic source more energy-efficient, achieving up to a 60% energy-saving efficiency, while also minimizing the heat generated by the hydraulic system.
3) The hydraulic power unit is cooled by the built-in air-cooling system, allowing for immediate cooling upon power-on without the need for additional cooling water connection.
3. Software Features
User-friendly software interface, simple operation, flexible settings, automatically and continuously loads smoothly according to test standards, auto-holds load, automatically collects and stores data, plots curves, automatically generates and prints test reports, and test data is exportable and traceable.
The software provides online prompts for the current work status and operation steps.
