MODEL JBDW-300B-196 COMPUTER
CONTROLLED
LOW TEMPERATURE AUTOMATIC
FEEDING PENDULUM IMPACT TESTING MACHINE
Introduction
Model JBDW-300B-196
Computer controlled low temperature
automatic feeding impact
testing machine can be used to
measure the impact resistance of metal materials
under dynamic load. It is a necessary testing instrument for
metallurgical machinery manufacturing and other units. It is also an
indispensable testing instrument for scientific research units to
carry out new material research.
Main Features
-
The impact testing machine adopts liquid
nitrogen refrigeration, and the minimum temperature can reach
-196℃. It is especially suitable for measuring the impact
resistance of metal materials
at extremely low temperature. It is an
important testing means for metallurgical, mechanical
manufacturing, scientific research and testing units to test
materials and research and develop new materials.
-
The main machine of
the testing machine is of split structure, cantilever hanging
and swinging mode, and the pendulum body is U-shaped.
-
The impact knife is fixed by screws, which is
easy to replace.
-
The sample is supported by simply supported
beam, and the end face of the sample is positioned.
-
The main machine is
equipped with safety pin and safety net.
-
This impact
testing machine carries out impact test on metal materials
according to the national standard GB/T 3808-2002
“Pendulum
Impact Testing Machine” and
GB/T 229-2007
“Metal
Charpy Pendulum Impact Test Method”.
