3.Key description

1. Host machine: This machine adopts desktop dual space structure, which can be adjusted steplessly by lifting and lowering. The test space can be changed after changing the column, screw and cover. The transmission system consists of a dedicated reducer for stepper motor control, a circular arc synchronous toothed belt, and a screw pair. No pollution.

2. Attachment: one pair of fixtures, other fixtures are purchased separately, and accessory fixtures are available.

4.Function introduction

a) The stepping motor is adopted, which has stable and reliable performance, and has protection devices such as overcurrent, overvoltage, overspeed, and overload. The speed ratio can reach 1: 5000.

b) The electrical control circuit is based on international standards and meets the national test machine electrical standards. It has strong anti-interference ability, which ensures the stability of the controller and the accuracy of the experimental data.

c) Condition saving: test control data and sample conditions can be made into modules, which facilitates the batch test;

d) Automatic speed change: The speed of the moving beam during the test can be changed automatically according to a preset program or manually;

e) automatic calibration: the system can automatically achieve the accuracy of the indicated value;

f) Process realization: The test process, measurement, display and analysis are all completed by a computer;

g) Batch test: For samples with the same parameters, it can be completed sequentially after one setting;

h) Test software: Chinese WINDOWS interface, menu prompts, mouse operation;

i) Display mode: The data and curve are dynamically displayed with the test process; curve traversal: after the test is completed, the curve can be reanalyzed. Right-click in the curve display window to pop up the graphical operation menu:

j) Curve selection: stress-strain, force-displacement, force-time, displacement-time and other curves can be selected for display and printing as required;

Test report: The report can be prepared and printed according to the format required by the user; it has a network interface for data transmission, storage, printing records and network transmission printing, and can be connected to the internal LAN or Internet of the enterprise.

k) Limit protection: with two levels of program-controlled and mechanical limit protection;

l) Automatic stop: After the sample breaks, the mobile beam will stop automatically;
