Overview
Yunda YD-LJ-W (10kg) Universal Tensile Strength Testing Machine (Vertical) is a professional testing equipment, widely used in rubber, Plastic film, braided belt, packing belt, Wire and cable, Spinning & weaving products, wire and other metals, Non-metallic and composite tensile strength and elongation testing. It is suitable for scientific research institutes, Universities & colleges, industrial and mining enterprises, technical supervision, commodity inspection and arbitration departments.
Features
1. Using imported electrical components and high-speed data processing, large LCD display full Chinese operation menu, can enter sample parameters in advance, automatically calculate and output the maximum force value, elongation, maximum tensile strength, support multiple sets of data storage.
2. Stepless speed range 0.5-500 mm/min, the screen real-time display test force, peak value, speed and running status.
3. Single space test structure, tension and compression bidirectional force value sensor, tensile or compression test is completed below, and the test method can be selected in advance.
4. Driven by precision digital motor and digital speed control system, the precision screw pair is loaded by the deceleration system, and the transmission is stable, low noise, high accuracy, wide speed control range and long life.
5. It has the functions of peak holding, sample breaking and shutdown, return to the origin after the test, and various protections such as upper and lower mechanical limits and electrical overload.
6. A variety of test methods can be selected according to the test object, and corresponding fixtures can be selected to complete tensile, compression, tearing, bending, disbonding, ring stiffness and other tests.
7. Using imported motor, low noise, accurate control; notebook display Chinese/English menu, real-time display of stretching time, load tension, can display printing tensile curve.
8. Directly display measurement results and print statistical reports, including mean, standard deviation and coefficient of variation.
9. Variable sample size and stretching speed, support standard size or custom settings.
10. Degree of automation, with automatic reset, data memory, overload protection function.
11. The built-in network port can be equipped with computer software to provide data communication.
12. Measurement range, can be converted by configuring different dynamometers, suitable for all kinds of paper and material tensile testing.
Principle
The testing machine uses a precision digital motor and a digital speed control system as the driving device. After deceleration by the deceleration system, the precision screw pair is driven to load to achieve smooth transmission and High Accuracy control. The all-digital closed-loop control system supports test functions such as constant stress, constant strain, and constant displacement. The force value and displacement data are collected through the High Accuracy Sensor, and the results are processed and displayed in real time.
Applications
Rubber, Plastic film, Woven belt, Wire and cable, Spinning & weaving products, Wire and other metals, Non-metallic, composite tensile strength and elongation testing, Research institutes, Universities & colleges, Industrial and mining enterprises, Technical supervision, Commodity inspection and arbitration departments
Steps
1. Enter the sample parameters and test parameters in advance.
2. Select the test method (tensile or compression).
3. Set the appropriate stretching speed.
4. Start the test and monitor the test force, peak value, speed, and other data in real time.
5. Automatically calculate and output the results after the test.
6. Return to the initial test position manually or automatically.
Notice
• Make sure that the sample parameters are entered correctly before the test.
• Choose the appropriate test method and fixture according to the test object.
• Pay attention to the upper and lower mechanical limits and electrical overload protection settings.
• To avoid overload use, the maximum load value can be set for automatic protection.
• Regularly check the operating status of the equipment to ensure that the Sensor and motor are working properly.
