MODEL WDW-300E
COMPUTER
CONTROLLED ELECTRONIC
UNIVERSAL TESTING MACHINE
Main application:
WDW-300E computer
controlled 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
-
Equipped with hydraulic clamping
system.
-
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.
