A, use:
Instruments for measuring of cotton, wool, Chemical fiber and other strong Bundle fiber.
B, principle structure
Instrument is from the rack, the pendulum, the main components of other devices and buffer manipulation components. Belongs to a pendulum rod Bundle fiber fracture strength tester, the body is vertical, transmission part of the weight of the formula and to adjust its rate of decline in oil buffer, when Bundle fiber sandwiched between the upper and lower gripper, When and pulled the handle to lift the constraints on leverage, leverage by pressing hammer gravity deflected the piston and rod buffers simultaneously began to decline, the next holder along with the decline, this time by the fiber bundle tensile load, When the fiber bundle fracture, supported on curved rack detent lever backwards to stop the fan, can be read directly from the scale breaking load -cN strong number. Reset the rotation of the rotating six pawl disengaged from the rack, so strong scale reset.
C, Main Technical Data
1, strong test range: 0 ~ 3000cN
2, the gripper type formula:.. A waveform holder; b BU's jaws
3, lower gripper stroke: 0 ~ 50mm
4, the next holder rate of decline: 4 ~ 25mm / min
5, buffer: The adjustable hydraulic cylinder type device
6, nominal weight weight: 3Kg
