1. Brief introduction of WLY-50 microcomputer controlled slow tensile stress corrosion testing machine

   The WLY-50 type microcomputer controlled slow tensile stress corrosion testing machine uses a servo motor as a power source to drive a precision ball screw for loading, and a self-developed electronic testing machine closed-loop measurement and control system for automatic control of the machine, with simple structure and noise Low, high control precision, simple operation, etc. Mainly used to detect and study the mechanical properties of metal materials such as static permanent tensile, creep, stress corrosion, etc. It can be used in NaOH, NO3, H2S, CL solution, methanol, N2O4, NH3, humid air and water and other media The stress corrosion damage characteristic test of metal in the environment, the load, deformation, speed, time and test curve can be dynamically displayed in real time during the loading process, and the test results can be automatically saved after the test. The test results can be queried and printed, and the data of the test process can be exported .

2. Product function of WLY-50 microcomputer controlled slow tensile stress corrosion testing machine

1. With a remote control box, it can realize the fast/slow movement adjustment of the moving head, and the operation is flexible and can be switched at will;

2. It has the function of returning to the initial position after the test, which is intelligent, efficient and fast;

3. It has the limit protection function of the maximum working position and the overload and overcurrent protection function, which is reliable and safe;

4. Self-built powerful test database, test data can be saved, inquired and recalled at any time;

5. It can realize various control methods such as constant rate force control, constant rate displacement control, displacement retention and user self-programming control;

6. It can switch to display multiple test curves: stress-strain curve, force-deformation curve, force-displacement curve, force-time curve, deformation-time curve, displacement-time curve, force-strain curve. Partial enlargement of test curve, multi-curve overlay comparison;

7. It can work continuously for more than 3 months without failure, and the test can be continued on the basis of the original test after the power is restored.
