Product function and purpose

This machine is mainly suitable for the torsion test of various materials such as metal and non-metal shaft products and connectors, for static or dynamic torsion fatigue durability test, and can realize the measurement and control of torque and torsion angle. Increasing the corresponding environmental temperature test box can carry out torsion fatigue test of various parts environment simulation.

Performance features / advantages

1. The hydraulic rotary motor drive technology has the advantages of high efficiency, long service life, low noise and maintenance free;

2. The testing machine adopts "horizontal floor structure" with good dynamic stability, and the upper and lower parts of the test bench are convenient, random, safe and reliable;

3. The parameters required by different tests, such as torque, frequency and angle, can be set and displayed on the computer screen, and the test process can also be called and inquired at any time;

4. User interface: the test software can be operated under Windows system, and the microcomputer system can complete the test setting, working state control, data acquisition and operation processing. Simple and reliable human-computer interaction interface and data processing interface can complete different experimental requirements selected by users, display and print test results;

5. Open data structure: both result parameters and process data can be called randomly by users, which is very convenient for scientific research and teaching;

6. A variety of protection measures: in case of sample damage, fracture and equipment failure, the test machine will automatically stop the test and give an alarm. In the process of automatic control test, the testing machine has various electrical protection of overload, over angle, over temperature, electronic limit protection, over-current, over-voltage and other power links, software overload, mechanical mandatory safety limit protection, etc.
