YAW -A series Computer controlled servo pressure testing machine 

YAW-A type screen display hydraulic pressure testing machine (four-post) is mainly used for metal and nonmetal structures, long cylinder specimen mechanical testing can also be used for general metal and nonmetal specimen compressive strength test. Increasing the bending test device (also known as anti-bending beam, is accompanied optional), but also on the bending performance test specimens. Application of modern computer measurement processing technology, the use of computer to test the whole process of acquisition, data processing and the testing results show that is to meet the requirements of modern mechanics testing new test equipment, is also a traditional dial and upgrading products of digital display type machine It made of the host machine, the hydraulic pressure source, computer acquisition and processing systems and other components.

1. Cases in different loading rate of sample precision compression test
2. Equipment has the test force and displacement of the two measurement channels as well as the realization and the corresponding test force, stress, displacement and other parameters of point by point measurement, loading rate by rotating the filling valve handle control at will.
3. Acquisition, processing, display the test data automatically, automatic measurement measured materials of all kinds of feature points;F, Rpc, Rtc, ReHc, ReLc, Rmc, Ec, etc.Also can according to user requirements of modify the test software testing standards, the eigenvalues of the measurement requirements.
4. Automatic drawing force - displacement, force - time, displacement - time curves and other tests, self-editing test reports, and timely printout.
5. It has a powerful database and a variety of interface format for users to choose, to help users achieve LAN communication
6. Equipment has the pressure, piston limit, beam lifting and other protective measures.
7. Host is cylinder underneath type, four column, beam, single space frame structure.
8. Lower platen is the car structure, you can walk on the track for easy loading and unloading of the specimen.
9. The plate is attached to the lower portion of the moving beam by beam spherical support and activities connected to the testing process can instantly adjust the parallelism between the pressure plate.
10. It has a larger test space and large-area platen, the biggest test space or pressure plate area can be manufactured in accordance with user requirements. According to the need can be bending test unit of choose and buy.
11. The host and application of YAW-A type microcomputer controlled servo pressure machine is same to YEW-A type screen display hydraulic pressure testing machine.
12. By the wide speed range of the electro-hydraulic proportional servo valve with computer and measurement and control unit of the servo control system, can accurately control and measurement test process.The whole machine by the host, servo hydraulic source, computer measurement and control system, and other parts.
13. With YEW-A type screen display hydraulic pressure testing machine function, can be carried out under the condition of servo control precision compression test (and increased after the bending test device of servo control under the condition of accurate bending/bending test)
14. With a test force, displacement of the two control channels and the corresponding test force thereto, between stress and displacement three control modes, control can be random / arbitrary switching; PID control parameters can be adjusted online.
15. rate test force can be like, constant stress, constant displacement, constant rate test.
16. can complete the triangular wave and trapezoidal wave lower axle loading in accordance with the set cycle test.
17. The system has an automatic zero, automatic calibration, continuous full measure, variable speed and other functions.
18. with automatic and manual control.
