Overview
HBO ZT-300 Desktop Electric Spring Testing Machine is a special testing equipment for precision springs. It adopts automatic control and data collection system to improve test accuracy and reduce operation requirements. It is mainly used for the detection of performance parameters such as spring deformation, tensile pressure, spring coefficient, etc. It can also be tested on resilience samples and similar parts. It meets the JB/T7796-2017 standard and supports national standards and ISO, JIS, ASTM, DIN and other international standards. It is suitable for industrial and mining enterprises, technical supervision, commodity inspection and arbitration, scientific research institutes, Universities & colleges, Quality control units and other departments.
Features
1. High Accuracy, High resolution, High Stability
2.7-Inch touch screen, friendly human-machine interaction interface, easy to operate
3.6 units of force value: N, kgf, lbf, gf, kN, tf
4.3 displacement units: mm, cm, in
5. Graduation can be set freely: force value Graduation can be set up to 4 decimal places; displacement Graduation can be set up to 4 decimal places
6. Four test modes: fixed height force measurement value, fixed deformation force measurement value, fixed force value to measure height, fixed force value to measure deformation
7. The test interface directly displays parameters such as force value, displacement, spring free length/height, deformation value, test time, speed, test point stiffness and average stiffness
8. 10 sets of test points can be customized, and the qualification interval judgment of the corresponding test parameters can be set
9. Linear dispersion and tabular display of test data
10. After the test is completed, the data bar is automatically saved, up to 10,000 pieces of data can be saved
11. The machine comes with a micro printer, which can directly print the test results
12. Comes with memory function, overload protection, emergency shutdown device, leakage protection device
Principle
This testing machine is driven by a stepper motor to achieve accurate displacement control, combined with an automatic data collection system to measure the force value and deformation parameters of the spring in real time. The system automatically performs the test and calculates the spring coefficient and other performance indicators according to the set test mode (such as the fixed height force value or the fixed force value to measure the deformation). The data is displayed and saved through Touchscreen.
Applications
Industrial and mining enterprises, technical supervision, commodity inspection and arbitration, research institutes, Universities & colleges, Quality control units
Standards
JB/T7796-2017, national standards, ISO, JIS, ASTM, DIN
Steps
1. Connect the power supply and turn it on.
2. Set test parameters through Touchscreen, including force value units, displacement units, test modes, etc
3. Install spring specimen in Test space
4. Start the test, the system automatically executes and displays the data in real time
5. After the test is completed, the data is automatically saved and the results can be printed
6. Shut down and disconnect the power
Notice
* Power supply voltage is 220V 50HZ to avoid voltage instability
Check whether the overload protection and emergency shutdown device are normal before operation
* When testing, pay attention to the sample installation firmly to prevent accidental peeling
Regularly calibrate equipment to ensure force and displacement accuracy
* Clean the pressure plate and Test space in time after use to keep the equipment tidy
* Avoid operating in humid or high temperature environments to prevent leakage or equipment damage
