Martel Electronics MECP10K - Manual (Page 2)

The MECP10K Hydraulic Hand Pump provides a hydraulic pressure
source up to 10,000 PSI. A wide variety of pressure media may be used;
distilled water, mineral based hydraulic oil, or up to hydraulic oil 100 (30W).
The seals are Fluorocarbon and the only other non-metallic materials are
plastic. Viscous oils above 30W should not be used.
CAUTION: Hydrocarbon fluids should never be used in oxygen
service applications.
1. Isolate the device to be calibrated. CAUTION: Do not connect to
high pressure sources. Safe operating procedures must be
exercised to avoid personal injury and damage to the calibration
system.
2. Select a fluid compatible with the system and the MECP10K.
Remove the fill cap and fill the reservoir to the fill line. During usage
do not allow the fluid level to drop below 50% of the reservoir
capacity. (Doing so will allow air to be introduced into the test
system).
3. Care should be exercised to minimize the total test system volume.
Connect the device(s) to be calibrated to the pump port(s) using
fittings or braided hose with the appropriate pressure ratings.
4. Adjust the vernier control to the mid position and close the needle
bleed valve.
5. Push the stroke limiter into the prime mode to allow the handles to
have maximum travel. With the hose to the device under test open
to air squeeze the handles to begin the priming process. (See
figure 1). NOTE: This can take many strokes of the pump
depending on the volume of the system and if the pump has not
been used for a while. It is important to use the full stroke of the
handles to make sure a full charge of hydraulic fluid is pulled from
the reservoir with each stroke.
6. Once the fluid starts to exit the end of the hose connect the hose to
the device to be calibrated and continue to squeeze the handles
until the reference gauge starts to show a sharp rise in the
pressure. At this point squeeze the handles and push the stroke
limiter into the pump mode thereby limiting the stroke of handles.
NOTE: failure to use the stroke limiter will greatly reduce the
mechanical advantage the user has and will limit the maximum
pressure that can be generated with reasonable handle pressure.
7. NOTE: Air in the system should be minimized because it
can effect calibration and high pressure gases can be
dangerous. It may be necessary to "prime" the test system
to eliminate gases. Repeat until bubbles are not seen in the
reservoir.
