d. Inspect all vacuum pump control devices (such as flow control valves, solenoid valves, orifices, etc.)
to
make certain that they have been located in accordance with the
BeaconMedæs
installation drawing(s).
Make certain that these components are correctly oriented in the piping scheme in order to achieve the
proper direction of flow and functional operation.
e. Open the shut-off valve for the seal liquid supply and the initial prime bypass shut-off valve. Allow the
seal liquid to flow until it flows from the pump discharge to prime the pump. Close the initial prime
bypass shut-off valve.
f. Remove the motor fan guard and rotate the motor fan in the specified direction of rotation as marked on
the pump body. Because of the direct-drive configuration, the pump shaft will also turn.
THE PUMP
SHAFT MUST ROTATE FREELY
. If the pump shaft is bound and cannot be turned freely by
rotating it manually, contact your
BeaconMedæs
representative for assistance. Reinstall the guard.
B.3.5 Start-Up and Operating Checks
Once the preliminary inspection and pre-operational check procedures have been completed, start the pump and
check pump operation as follows:
a. Make certain that the pump is primed and the shut-off valve for the seal liquid supply is open.
b. Apply power to the drive motor.
c. Check the speed of the pump shaft rotation with a tachometer and compare the measured speed with the
rated rpm for the pump. The rated rpm and capacity can be determined from the Engineering Data Sheet
or by consulting your
BeaconMedæs
representative. (A test rpm is shown on the nameplate fastened to
the pump lobe; however, this nameplate data may not show the exact operating speed for your
application.)
d. Maintain a constant check on the temperature of the pump casing. If the temperature rises rapidly or is
25°F (14°C) or more above the temperature of the seal liquid,
SHUT DOWN THE PUMP
IMMEDIATELY AND DETERMINE THE CAUSE
.
e. Check the temperature at the motor bearing housing areas. The temperature should not exceed the limits
specified in the motor manufacturer's instructions.
WARNING
Do not attempt to free a pump shaft from a binding or bound condition by
applying power to the drive motor. Severe damage may result.
WARNING
Never operate the pump without adequate prime and service liquid flow.
Severe damage may result. High service liquid supply pressures do not
necessarily indicate that the flow is adequate. Check for flow from vacuum
pump discharge or water trap silencer.
WARNING
If the pump is to be checked in a system, notify the appropriate hospital
personnel before placing a pump on line, particularly when placing the
pump online for the first time. Starting up a system unexpectedly may
cause personnel injury.
