Electro-hydraulic universal testing machine for static testing of different materials, high precision, good repeatability; Tensile, compression, bending, shearing and stripping tests of various materials can be carried out according to relevant standards, or strain or other better test methods can be used, so what are the functions and application characteristics of rail hex bolt?

What are the functions and application features of rail hex bolt?

The electro-hydraulic universal testing machine integrates servo automatic control, automatic measurement, data acquisition, screen display and test result processing. With imported oil pump, electro-hydraulic servo valve and PC servo controller as the platform, the multi-channel closed-loop control is realized, and the automatic control and automatic measurement functions are completed in the test process. It has the characteristics of good professionalism, high reliability and easy upgrade. It can be continuously enriched and improved with the development of testing and control technology and the change of testing standards.

1. The testing machine uses a microcomputer controlled full digital broadband electro-hydraulic digital valve to drive the hydraulic cylinder, automatically control the test force, displacement and deformation of various modes, and complete the tensile, compression and bending test of the sample. The expert system with fully digital programmable amplifier and intelligent setting control mode can realize closed-loop control of various modes, complete tensile, compression, bending and shear tests of metal and non-metal materials, and can automatically calculate elastic modulus E and other parameters. It belongs to the requirements of material tensile test method at room temperature and other standard requirements.

2. The testing machine adopts hydraulic cylinder under; The bottom of the testing machine is equipped with a power and transmission device to adjust the test space, and the transmission is stable; The upper and lower clamp seat is fully open structure, with automatic hydraulic clamping system, easy sample clamping, good stability, automatic control, measurement, data acquisition and processing, drawing and printing test curve and test report.

3. The machine can realize the speed control of test force, deformation and displacement, and the control error is better than 1% of the set value. During the test process, the control speed and control mode can be smoothly switched and maintained at will; Test force overload automatic protection function, its protection range can be arbitrarily set; It can be networked between computers and is suitable for large-scale laboratory management.
