The oil cylinder mounted under the host space is at the top of the stretch, compression, bending test space is at the top of the table under the beams and between.
Down under the crossbar by the gear motor, chain drive mechanism, Ball Screw drive, to achieve tensile, compression of space to adjust
Hydraulic principles as shown, for the load adaptive speed control system into the oil throttle, manual valve control test process.
Hydraulic oil tank high-pressure gear pump driven by the motor into the circuit, through one-way valve, 10μ high-pressure filter, pressure valve, valve delivery into the fuel tank. Manual control valve to send the oil through the size of the opening to control the flow into the tank to meet the load requirements. After the test, open the oil return valve cylinder unloading and to return. Upper and lower jaw of the clamping, release through two solenoid valve control.
4. Screen display and software system
4.1 with the test force, force, peak, sample deformation, piston displacement, the screen display the test curve.
4.2 can GB228-2002 "Metallic materials Tensile testing method at room temperature"in the data processing required to complete testing.
4.3 The original record the value of the test, reporting the value of the requirements of the standard GB228 rounding.
4.4 The loading rate can be manually controlled through the test force - time curve display.
4.5 metal tensile test can be automatically strike Fm, Rel, Reh, Rp, Rt, Agt, Z, A, Rm and other parameters, but also on Fel, Fm, etc. manually identified, and accordingly print the results. Different content available on request to print the reports and curves.
4.6 can output and print force - strain, force - displacement, force - time curve of 3 different forms.
When the test force exceeds the maximum test force each file to 2% -5%, the overload protection, shut down.
When the piston reaches the upper limit raised position, the travel protection, pump motor stops.
6. Attached
Accompanied by a full set includes: stretch attachments, accompanied by compression, bending attached.
7. Other
Install the debugging tools, seals, manual, certificate, packing list and other technical documents, see random.
