HST RCW-50E-5 5 station Computer Control Electronic high temperature creep testing machine
1. Features
5 station high temperature creep test machine is mainly used for the determination of tensile creep of metal materials under constant high temperature state, using a main engine frame, 5 station high temperature furnace and loading mechanism. Each test station can be controlled separately and can work independently. Five stations can be measured at the same time, and different types of tests can be done simultaneously.
2. In addition to the creep test, the test machine controller software can also complete the lasting test, stress relaxation test and cycle loading test (low weekly fatigue test). After the test software sets the test (test force / stress loading speed, test force / stress loading constant target value, test temperature) conditions, automatically record and save the test force / stress-time, deformation / stress-time, temperature-time curve.
3. Dual control system, with an independent large screen touch screen measurement controller, each machine can work independently, can also work online with the computer, the LCD touch screen durability is better than the push-button hand control box
4. The temperature can be set in real time on the touch screen and software, and can run automatically without pressing the temperature control table button. The test software automatically displays and records the temperature curve.
5.The GTC650 fully digital ARM measurement and control device and low noise sensor independently developed and produced by our company are adopted. The ARM chip adopts imported NXP chip from the Netherlands, and the system drift is very small, so it can fully meet the needs of creep and lasting long time test. The test software automatically records the test force / stress-time, deformation / stress-time, temperature-time curve.
6. The measuring controller and the computer form a distributed control system. All the functions of the test data, which can be online or disconnected from the computer at any time to receive or transmit data through the network interface; the data collection interval can be set according to time, deformation variation and test force variation. After the sampling starts, it has the function of deformation and zero password protection to prevent data loss caused by misoperation.
7. The controller can communicate with the temperature controller and control it to ensure that the whole experiment process is not disturbed by human beings, automatically heat up according to the experimental conditions, and automatically conduct the specified test when the set ambient temperature is reached.
8.Measures to ensure the long-term stable and reliable operation of the system (over 5000 hours) to overcome the drift of the side force sensor is the basis of electronic creep and lasting test machine. The strain force sensor is mainly affected by the creep of the internal elastomer of the sensor and the temperature of the sensor. We make the following treatment: The 50 KN creep and lasting test machine provided by our company uses 100 KN force sensor, which aims to minimize the impact of the creep of the sensor elastomer itself.
9.Unattended function. The test machine has automatic control, sensitive response and high accuracy. When beyond the adjustment range, alert the operator with sound and light alarm, and automatically stop, and no one needs to guard after the test starts.
10.The deformation measurement system first chooses the lead-out structure and adopts the bilateral grating ruler measurement to avoid the long time drift error of the strain extension meter.
11.Using Japan Panasonic drive system, stable and reliable.
12 The sensor sensor is used. High resolution, good linearity and high accuracy.
13. The high temperature temperature control table adopts Japan island power number display table or select configuration touch control temperature control screen, with high precision and good stability.
14. Test engine, measurement and control device, test software and high temperature furnace are independently developed and produced by our company, and the technology is mature and stable, and the after-sales service is guaranteed.
