The main body of the microcomputer controlled electro-hydraulic universal testing machine adopts a cylinder mounted main body, which adopts microcomputer control and display functions! Mainly used for tensile, compressive, bending, and shear tests of metals and non metals. Suitable for fields such as metallurgy, construction, light industry, aviation, aerospace, materials, universities, research institutions, etc. The experimental operation and data processing comply with the requirements of GB228 "Metallic Tensile Test Method for Room Temperature Materials".
Functional Features
1) Flexible protective devices are installed on the upper sliding surfaces of the lower crossbeam and clamp plate to ensure that oxidized inclusions do not fall into the sliding surfaces of the working clamp and clamp plate during sample stretching, thereby extending the service life of the clamp plate.
2) The central axis of the upper and lower jaws is equipped with a compound cylinder hydraulic automatic fixture, which is controlled by a movable manual control box (which controls the clamping and releasing of the upper and lower jaws, and the lifting and lowering of the lower crossbeam).
3) The processing of all components of the product is controlled and managed under the internal ISO9001 quality management system of the company. The key components purchased externally are all imported with original packaging, effectively improving the accuracy and long-term stability of the equipment.
4) By adopting unique pressure following technology, the working pressure of the oil cylinder always changes with the size of the load, thereby reducing the noise during equipment operation, lowering oil temperature, and improving hydraulic control accuracy.
5) A unique piano desktop oil source cabinet with high integration and convenient operation can effectively reduce product footprint.
6) Low noise, below 50 decibels at maximum working load, basically in a silent state. Pressure follow-up is 70% more energy-efficient than conventional equipment, with high control accuracy of up to one ten thousandth (compared to five thousandths for conventional products). No control dead zone, with a starting point of up to 1%. The oil circuit is highly integrated with few leakage points.
7) Multiple high-speed CPUs work in parallel, achieving true multitasking parallel and simultaneous operation.
8) Module unit: Multiple accessories can be flexibly interchanged, and the industrial control bus style electrical hardware is convenient for functional expansion and maintenance.
9) Combined with the modular structure of the industrial control bus slot, it makes function expansion easier and maintenance services more convenient.
10) A high-precision ± 500000 code acquisition card with a resolution of up to 1/± 500000 code, maximizing the measurement range of the sensor.
11) Using PnP (Plug and Play) technology between computers and Windows systems to automatically recognize inserted cards.
12) The backup support for sensor correction data provides highly reliable data measurement accuracy.
13) The scene based operation menu display makes it easy and clear for you to switch between different menus.
14) The active test bench position memory function can achieve software set test bench position protection.
15) The maximum counting frequency for digital quantities is 10M, ensuring accurate counting of displacement and large extension digital quantities.
16) The anti jitter frequency doubling technology of encoder signals significantly improves the resolution of displacement and large extension by several times.
17) The closed-loop control function of any channel not only achieves three closed-loop controls of load, displacement, and strain.
18) The fast and independent overload protection function quickly protects the safety of the equipment in case of overload.
19) The position limit of the associated three-level test bench ensures foolproof protection.
20) Software system: A software package for the Chinese Windows 2000/XP platform, with a beautiful and elegant interface. It has software operation authorization management function. The operator can only start the test software after logging in with a password and confirming with the system.
21) Multiple uses: It can perform tensile, compressive, bending, shear, peel, tear and other tests on metal, non-metal and components. Can meet various testing method standards such as ISO, JIS, ASTM, DIN, GB, etc.
22) Easy to operate: It has an operation guide and online help function, making the system operation very simple.
23) Automatic input of sample size: The computer automatically collects the sample size, greatly reducing the tedious input of operators after measuring the sample size, and also avoiding the deviation of test results caused by input errors again.
24) The testing method is programmable, and users can develop their own testing methods according to different testing requirements.
25) Memory return: After the experiment is completed, remove the sample button, and the upper jaw can automatically return to the initial position of the experiment.
26) Automatic calibration: Load and elongation can be automatically calibrated according to the added standard values.
27) Automatic recognition: After the sample is damaged, it is automatically recognized and automatically stopped to prepare for the next work program.
28) Peak holding: During the testing process, the maximum value of the test item follows the progress of the experiment and is always displayed on the screen.
29) Control mode: It has multiple control modes such as displacement control, force control, elongation control, stress control, strain control, constant load, constant strain, etc.
30) Editable complex test program: For example, it can be divided into four stages. The first stage is preloading, and the other three stages can freely choose six control methods: displacement control, load control, elongation control, strain control, stress control, speed, etc. The control parameters of each stage can be set arbitrarily and automatically switched without impact.
31) Easy to zero: Load, elongation, and displacement can be manually zeroed with just one button press. The system can also automatically zero at the beginning of the test.
32) Data editing: After the experiment is completed, data can be edited on the experimental curve using the mouse.
33) The unique displacement method is used to obtain the yield strength of materials without obvious yield, which specifies a non proportional elongation stress Rp0.2.
34) Multiple curves: Multiple curves can be selected, including true stress-strain, engineering stress-strain, load elongation, load time, stress time, strain time, etc. One of the curves can be displayed in real time, or switched to other curves as needed.
35) Curve comparison: The curves of the same group of samples can be overlaid for comparison or printed.
36) Extended analysis: Any segment on the experimental curve can be locally magnified for analysis.
37) Report programming: can output different report formats according to user needs
38) Automatically calculate: Fm ( Fb )、Feh、Fel、Fp、Rm (σb)、ReH (σsu)、ReL (σsl、σs)、Rp0.2 、Rp0.1 (σp0.2)、Rp0.05 (σp0.05)、Rp0.5 (σp0.5)、E、Et、Ec、Z（ψ）、A (δ)、τ Wait for the test parameters of GB/T 228-2010 standard and select the output parameters. Data files can be stored in multiple formats.
39) Powerful testing software that can achieve networking with detection data management software.
