Connect the 5000psi maximum pressure
gauge to the upper connection of the
Calibration Piping Assembly using the quick
connect coupling assembly. See
Figure 9
:
NOTE:
Each of the four pressure gauges
that come equipped with the apparatus are
equipped with quick connect couplings for user
friendly connection and disconnect.

3.
Close Right-Hand Needle Valve. Refer to
Figure 3, Item 10
.
4.
Open Left-Hand Needle Valve. Refer to
Figure 3, Item 8
.
5.
Press Gear Switch
(Figure 4, Item 15)
to
simulate a 40-tooth flow rate.
6.
Turn on Drive Motor / Circulating Pump
Switch. Refer to
Figure 4, Item 13
. The
hydraulic oil will begin circulating through the
system.
NOTE:
During operation and while hydraulic oil
is flowing throughout the system the reservoir
volume should be at least ¼ filled with oil.
7.
Wait for a period of at least 25-30 minutes for
the oil to completely circulate throughout the
system at the test temperature.
8.
Open Right-Hand Needle Valve. Refer to
Figure 3, Item 10
.
9.
Close Left-Hand Needle Valve. Refer to
Figure 3, Item 8
.
10.
Observe the hydraulic oil flow as it drips from
the Calibration Piping Assembly exit port. See
Figure 10, Item 26
.
NOTE:
It is recommended to place a
small collection beaker or towel underneath
the exit port while the hydraulic system is
being primed.
11.
Once a steady flow or constant drip rate is
observed, the hydraulic system is primed and
free of air bubbles.
12.
Using the relief valve at the right-hand side of
the calibration piping assembly
(Figure 10,
Item 25)
, turn counter-clockwise to completely
open the valve. This allows the system to flow
at atmospheric pressure and will serve as the
reference value (100% free flow delivery) of
the calibration curve vs. pressure, psi.
13.
Place a 60-mL Saybolt Receiving Flask
(Figure 10, Item 27)
or other receiving device
capable of collecting 60-mL of oil, under the
exit port and start a timer.
14.
Determine the delivery time for 60-mL of
hydraulic oil to flow and calculate the flow rate
in cubic centimeters per second assuming 1
mL equal to 1 cm
3
. Again, this calculated flow
rate is the 100% free flow delivery value on
the calibration curve vs pressure.
15.
To obtain additional points for the curve
perform
the
60-mL
timing
observation
sequence at 500, 1000, 1500 psi and at
sufficient pressures above 1500 psi.
16.
Turn the relief valve clockwise to increase the
pressure to 500psi, place the 60-mL flask
under the exit port and measure the delivery
time for 60-mL of hydraulic oil to collect.
17.
Repeat this procedure for 1000psi, 1500psi
and pressures above to develop a sufficient
calibration curve.
18.
Finally, repeat the entire procedure for the
same pressures using the 64-tooth flow rate
by pressing the Gear Switch
(Figure 4, Item
15)
.
19.
When Calibration Curve is determined and
sufficient for use, open the Left-Hand Needle
Valve
(Figure 3, Item 8)
and close the Right-
Hand Needle Valve
(Figure 3, Item 10)
.
