Overview

YYF-40 slow strain rate tensile stress corrosion testing machine. According to different experimental requirements, the working conditions of the environmental container can be raised from normal temperature and pressure to over 22MPa (3300 psi), 350 C. This high-temperature and high-pressure container is specifically designed for conducting tensile tests in simulated high-temperature and high-pressure corrosive environments on site. *The high-temperature and high-pressure container adopts a dynamic sealing device to achieve loading experiments of test samples in high-temperature and high-pressure environments.

Product Details

YYF-40Slow strain rate tensile stress corrosion testing machineFunctional purpose:

The slow strain rate corrosion testing machine provides users with a method that can withstand high temperatures
An effective method for conducting tensile tests on metal materials in high-pressure corrosive environments.
Under the control of the computer control system, this testing machine can complete constant rate tensile tests
Various tests such as constant stress creep test, corrosion fatigue test, crack growth rate test, etc.

YYF-40Slow strain rate tensile stress corrosion testing machinePerformance characteristics:
1. Adopting a highly integrated, powerful control, data processing capability, and high reliability control measurement system.
2. Adopting a fully digital, three closed loop (force, deformation, displacement) control system based on neuron adaptive PID algorithm to achieve fully digital three closed loop control of force, deformation, and displacement. The control loops can be automatically switched between, and a smooth transition without impact can be achieved when switching between different modes.
3. Multiple closed-loop control modes such as positioning, fixed speed, fixed strain, fixed strain rate, fixed load, and fixed load rate can be implemented.
4. High precision 24 bit data acquisition system, high resolution, expandable to 8-channel AD acquisition.
The entire control system has high cost-effectiveness and high reliability.
6. It can be adjusted at any speed during the testing process to improve testing efficiency.
7. The entire testing process is controlled by a microcomputer, which dynamically displays the load value, displacement value, deformation value, testing speed, and testing curve in real time.
8. Data processing and analysis are carried out using a microcomputer, and the test results can be automatically saved. After the test is completed, the test curve can be retrieved again, and the test process can be reproduced by traversing the curve, or curve comparison and curve amplification can be performed.
9. The synchronous belt circular arc tooth symmetrical reduction system has the advantages of high efficiency, long service life, low noise, and no maintenance required. Adopting phase-locked loop pulse position control mode, without drifting or misalignment
10. The data can be easily imported into an EXCEL spreadsheet, making it convenient for users to process later.
