Overview
HBO ZT-20 Desktop Electric Spring Testing Machine is a special equipment for spring performance testing. It adopts precision automatic control and data collection system to improve test accuracy and reduce operation requirements. It is mainly used for spring deformation, tensile pressure, spring coefficient and other parameters testing, and can also test resilience samples and similar parts. It meets JB/T7796-2017 standards. It 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
The testing machine adopts a precision automatic control and data collection system, which is driven by a stepper motor to achieve accurate measurement of spring deformation, tensile pressure and other parameters. The system automatically performs tests and collects data according to the set test mode (such as fixed height force measurement value or fixed force value to measure deformation), and displays force value, displacement and other parameters in real time through the Touchscreen interface, and supports data saving and printing.
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. Turn on the power of the device and start the system.
2. Set test parameters through 7-inch Touchscreen, including force value units, displacement units, Graduation, test mode, etc
3. Customize test points (up to 10 groups) and set the qualification interval
4. Place spring or resilience specimen in Test space
5. Start the test, the device automatically executes the test and displays the data in real time
6. After the test is completed, the data is automatically saved or the results are printed through a micro-printer
7. Power off the device
Notice
• Power supply voltage 220V 50HZ
• Check that overload protection and emergency shutdown devices are functioning properly before operation
• Avoid use in humid or flammable environments, pay attention to leakage protection
• Do not touch moving parts during the test to prevent accidental injury
Regularly calibrate equipment to maintain accuracy and comply with relevant standards
