When selecting a hydraulic universal testing machine, users need to decide whether to choose a servo valve controlled or servo pump controlled system based on factors such as testing requirements, accuracy requirements, ease of operation, and budget.
Hydraulic universal testing machine controlled by servo valve
1. Characteristics:
-High precision control: Servo valves can achieve high-precision closed-loop control, suitable for experiments that require precise control of test force, displacement, and deformation.
-Multiple control modes: Supports multiple control modes such as constant velocity test force, constant velocity displacement, constant velocity strain, etc., and can be smoothly switched.
-Superior dynamic performance: suitable for conducting dynamic tests such as fatigue tests, creep tests, etc.
-Good adaptability to complex experiments: can meet the testing needs of high stiffness materials such as metals and composite materials.
2. Applicable scenarios:
-High precision testing: fields such as aerospace and materials science research that require extremely high testing accuracy.
-Dynamic testing: occasions that require cyclic loading and fatigue testing.
-Large tonnage test: Testing of large tonnage materials weighing over 30 tons.
Hydraulic universal testing machine controlled by servo pump
1. Characteristics:
-Energy saving and efficient: Servo pumps can dynamically adjust flow and pressure according to experimental requirements, resulting in significant energy-saving effects.
-Low noise operation: Compared to traditional hydraulic systems, servo pump controlled systems operate more smoothly and with lower noise.
-Strong adaptability: suitable for experimental scenarios with large load changes.
-Easy to operate: The system design is simple, easy to operate and maintain.
2. Applicable scenarios:
-Conventional material testing: such as tensile and compressive testing of building materials and ordinary metal materials.
-Small and medium-sized tonnage testing: testing requirements for less than 30 tons.
-Environments that require energy efficiency and noise, such as laboratories and precision machining workshops.
Choose Suggestions
-If the testing requirements require high precision and dynamic performance, it is recommended to choose a hydraulic universal testing machine controlled by servo valves.
-If the experimental requirements place more emphasis on energy saving and ease of operation, and the test load varies greatly, it is recommended to choose a hydraulic universal testing machine controlled by a servo pump.
-For the testing needs of small and medium-sized tonnage, servo pump controlled systems may be more cost-effective.
Users can choose the most suitable hydraulic universal testing machine control method based on their own testing needs, budget, as well as factors such as testing accuracy, operational convenience, and energy-saving requirements.
