Product Details
1. Main applications and characters
- The tensile stress relaxation testing machine adopts horizontal
structure. Its test space is made up of four columns and working
bench. Below the working bench, there is driving system which is
made up of servo motor, reduction box and lead screws. The lower
jaw is driven by the lead screw. Via the movement of the lower jaw,
the force is loaded to the specimen. This structure make the
machine possess high rigidity, which can ensure the accurate of the
test results.
- There is software designed according to the test standards GB/T
10120 and ISO15630 installed on the computer. Users can control the
test procedure through the software. The main test parameters (test
force, relaxation force, relaxation rate or logarithmic relaxation
rate and temperature can be displayed and saved on the computer.
After the test, the test curves(including curves of residual test
force, relaxation force, relaxation rate, temperature versus time)
and test results can be printed out or be saved on the computer.
- Power of main machine can be cut off while set test force is
reached to reduce energy consumption.
- Test data will not be lost when there is an outage. And test will
continue when the power is on.
