Generating pressure
After the commissioning with ventilation, you can generate pressure with the P 700 T. With
increasing back-pressure in the system, the pumping becomes more and more difficult.
WARING! Risk of injury if maximum pressure is exceeded!
Observe the maximum permissible pressures of the individual components in the meas-
urement setup. If the limits are exceeded, this can lead to material failure and injuries.
Stop pumping if the maximum permissible pressure has been reached or an exceed-
ed measuring range is displayed.
CAUTION! Material damage to test sample!
Depending on the volume of the measurement setup, a high pressure can be generated
with only a few pump movements if the hand lever is fully deflected.
Observe the maximum pressure of the test sample.
Use the hand lever to create a prepressure which is less than the required test pres-
sure. Then, carefully increase the pressure with the fine adjustment valve.
Operating notes:
Observe the following notes when operating the P 700 T:
•
Ensure that there is sufficient hydraulic oil in the reservoir.
If necessary, refill the hydraulic oil. This must also be ensured during depressurisation
(
§ 5.3).
•
For small hydraulic volumes and well-ventilated systems, a high pressure is already built
up with a few pumping movements.
Ensure that the maximum permissible pressure is not exceeded.
•
Starting from ~ 200…400 bar, the pressure can only be poorly adjusted with the hand lever.
In this case, increase the pressure via the fine adjustment valve (
p. 33).
Operating the P 700 T:
Switch on reference and test sample (if
necessary).
Close pressure relief valve:
•
Turn the knob of the valve clockwise until it
stops.
Generate pressure:
•
Move the hand lever up and down:
The pressure is built-up.
•
Repeat the pumping movements until the
necessary test pressure is approximately
reached.
