The new UNIFLEX® hose line test bench P
200 E with the digital
microprocessor based UNIMATIControl®-E system
and the special clamping system with sealing cones makes testing
of hose pipes up to I.D. 1" (DN 25) even more flexible,
quicker and simpler.
All test data are entered in the easy-to-use, menu-assisted control,
and, if necessary, they can be saved under a freely selectable
number. The fact that any saved test data can be called up again
results in a considerable reduction of setup times and ensures
repeat accuracy. Moreover, a test record of every test can be printed
out, documenting the result in "black and white". Due
to the patented clamping system with sealing cone, screwing operations
and hundreds of threaded adapters are no longer needed. The hose
is simply placed into the spacious test chamber, filled with the
test medium, clamped hydraulically, subjected to a static load
up to 3000 bar (43500 psi), and emptied automatically.
Loading - One end of the hose line is inserted in a fixed,
stationary testing head, the other end is placed in a movable testing
head. The fittings are then located between quick- release locks
and cone-shaped sealing heads. A hydraulic unit supplies the precisely
adjustable clamping pressure to the sealing heads.
Testing - The filing pump rinses and ventilates the hose
line in the test chamber. After the window is lowered, the previously
set clamping and test pressure is generated automatically. The hose
line can be observed in the well lighted test chamber. During the
test, additional pressure surges can be applied to the hose line
when the system is in manual mode. An environmentally acceptable
water-and-oil emulsion is used as the test medium (certificates
of the Bavarian Biological Testing Institute and the Institute for
Hygiene in Essen, Germany).
Blowing Out - The pressure test is ended with one push of
a button, i.e. the test pressure is reduced and the blow- out time
has expired, the hose line can be removed from the machine.
