MODEL WDS-20E
DIGITAL DISPLAY ELECTRONIC
UNIVERSAL TESTING MACHINE
Main application:
WDS-20E digital
display electronic
universal testing machine is mainly used for testing and analyzing the tensile,
compression, bending, shearing, tearing, peeling and other mechanical properties
of non-metallic materials, such as metal wire, rubber plastic, waterproof roll,
wire and cable, chemical fiber textile, etc. according to GB, ISO, JIS, ASTM,
DIN and various standards provided by users.
It is
an ideal testing equipment for scientific research institutes, colleges and
universities, industrial and mining enterprises, technical supervision,
commodity inspection and arbitration departments.
Main machine
-
The main machine adopts
floor type frame structure with high strength, small deformation and
beautiful appearance.
-
Imported high-precision ball screw is adopted, with
efficient and stable transmission.
-
High precision spoke load sensor is adopted, with high
measurement accuracy and good stability.
-
The transmission part adopts circular arc tooth
synchronous belt transmission, and there is no gap in both directions during
the transmission process.
-
AC servo motor and drive system are adopted to ensure
stable transmission and torque, with overcurrent, overvoltage, overload and
other protection devices, and the speed regulation ratio can be greater than
1:100000
-
The clamp is specially designed, with firm clamping,
convenient operation and no jaw slip.
-
The special process ensures the coaxiality of the testing
machine and eliminates the influence of irregular samples on the sensor.
Control system
The full digital closed-loop measurement
and control system has many advanced characteristics and technological
innovations:
-
Four closed-loop controls of test force, sample
deformation, beam displacement and test process are realized.
-
The data acquisition system consists of 4 high-precision
32-bit A / D conversion channels. The highest resolution is 1 / 300000, and
the whole process is not divided.
-
Original famous brand integrated devices are selected,
with full digital design.
-
Comply with PCI bus standard, microcomputer automatic
identification and installation, and achieve "plug and test".
-
The electronic measuring system has no potentiometer and
other analog components to ensure interchangeability and facilitate
maintenance and replacement.
