Product description:

WDW-D series of computer-controlled electronic universal testing machine
WDW-D series of computer-controlled electronic universal testing machine (door)
• The main purpose:
W DW-D series of computer-controlled electronic universal testing machine is mainly used for metal and nonmetal materials tensile, compression, testing and analysis of mechanical properties of bending, shear, tear, according to GB, ISO, JIS, ASTM , a variety of standard and user-supplied DIN testing and data processing, scientific research institutes, universities, industrial and mining enterprises, technical supervision, inspection and arbitration department of the ideal test equipment.
• Features:
1 Host
1.1 host high degree of portal frame steel structure, high strength, small deformation;
1.2 imported high-precision ball screw, drive smoothly and efficiently;
1.3 Transmission part adopts arc tooth belt drive, two-way transmission process without gaps;
1.4 AC servo motor and drive system to ensure smooth transmission, torque stability, with overcurrent, overvoltage, overload protection devices, speed ratio can be large 1: 100,000;
1.5 jig specially designed holding firm, easy to operate, no jaw slippage;
1.6 special process to ensure concentricity test machine, good to eliminate the irregular sample sensor.
2 Control System
1, to achieve the test force, the specimen deformation, beam displacement and four closed-loop control of the test process;
2, the data acquisition system consists of four high-precision 24 A / D converter channel consisting maximum resolution of 1/300000, entire file, regardless.;
3, the choice of BB, AD, Xilinx and other original brand integrated devices, digital design;
4, in line with the PCI bus standard, computer automatic identification and installation, so Plug and Measure;
5, electronic measuring system without potentiometer and other analog components to ensure interchangeability, easy maintenance and replacement.
