Overview
YONGLIDA WDW-50 electronic universal testing machine is a mechanical properties testing equipment with beautiful appearance, easy operation and stable and reliable performance. It is suitable for testing various metals, Non-metallic and composite, and is widely used in Building materials, aerospace, machinery manufacturing, Wire and cable, rubber and plastics, Spinning & weaving, home appliances and other industries. It is an ideal testing equipment for scientific research institutions, Universities & colleges, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments.
Features
1. The programmable device CPLD is used to achieve high-speed processing, programmable amplification, and stable and reliable operation.
2. With force, displacement, deformation three closed-loop Control mode, real-time data display, and can display force-displacement, force-deformation, force-time and other test Linear dispersion.
3. After the test, the results of resilience modulus, upper and lower yield strength, tensile strength and elongation are automatically calculated.
4. Built-in GB/T 228-2002 and other metal or non-metallic test methods, with various reporting formats and database management standards.
5. AC servo speed control motor and system drive, through the arc timing belt and synchronous pulley deceleration drive precision screw pair loading, smooth transmission, low noise, high efficiency, high accuracy, wide speed range.
6. Equipped with a variety of protection functions such as peak holding, automatic shutdown of sample breakage, electrical overload, and upper and lower mechanical limits.
7. Tensile, bending, compression, shear, and other tests can be completed according to corresponding standards.
Principle
The testing machine adopts AC servo speed control motor and speed control system as the driving device. The power is transmitted through the deceleration system composed of arc timing belt and synchronous pulley, and finally drives the precision lead screw pair to generate loading force to realize the mechanical properties test of the sample. The control system is processed at high speed through the programmable device CPLD, and adopts three closed-loop Control modes of force, displacement and deformation to ensure the accuracy and stability of the test process.
Applications
Building materials, Aerospace, Machine building, Wires and cables, Rubber plastics, Spinning & weaving, Home appliances
Steps
1. Install the appropriate fixture according to the test requirements.
2. Clamp the specimen correctly on the testing machine.
3. Select or set the corresponding test method in the control system (e.g. the built-in GB/T 228-2002 standard).
4. Set test parameters, such as beam traverse speed.
5. Start the test, the equipment automatically loads, and displays data and Linear dispersion in real time.
6. After the test, the equipment automatically calculates and outputs the test results.
7. Generate and save or print the test report.
Notice
The equipment should use a single-phase 220V, 50Hz power supply with a power of about 1000W.
* Before operation, make sure that the sample is firmly clamped to prevent peeling during the test.
Pay attention to the upper and lower mechanical limits indicated by the equipment to avoid overrunning the beam.
* Regular maintenance of transmission components (such as timing belts, screw pairs) to ensure smooth operation and accuracy.
Non-professional personnel should not disassemble or adjust the electrical and control systems.
