This machine is a new generation of electronic multi-function testing machine specially designed for universities and scientific research institutes. The design of the testing machine host draws on international professional technology, with beautiful appearance, easy operation, stable and reliable performance. It is widely used in material inspection and analysis in construction and building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, textiles, medical, home appliances and other industries. , is a satisfactory testing equipment for scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments.
The machine adopts a fully digital speed regulation system and motor with high speed regulation accuracy and stable performance as the driving system, a fully digital controller as the core of the control system, and a touch screen as the operating interface for control and data processing to achieve test force, test force peak, The displacement, test deformation and test curve are displayed on the screen, and all test operations are completed on the touch screen. Good humanized design makes the test operation easier. Combining the above technologies, the machine can achieve nearly perfect closed-loop control of parameters such as test force and displacement, and can realize control modes such as constant stress and constant displacement, and can switch smoothly between various control modes. This machine meets the requirements of national standards, and can conduct testing and data processing according to GB, ISO, JIS, ASTM, DIN and various standards provided by users, and has good scalability.
ASTM, DIN, JIS, BS, GB/T528-1998/T529-1999, etc.
This machine can produce curve categories:
Load VS displacement, load VS time
Displacement VS time, stress VS strain, load VS two-point extension
A. High-precision force sensor: 0~1000N. Force accuracy is within ±1%.
B. Capacity segmentation: stepless speed change throughout the entire process, using high-precision 24 bits A/D, sampling frequency 200Hz, maximum resolution of the entire force 1/1000,000
C. Power system: servo motor + reducer + ball screw + linear bearing + high-precision sensor
D. The speed control system adopts servo speed control system and reduction motor, which has stable and reliable performance and has overcurrent, overVoltage, overload and other protection devices.
