Electrical
Connections
Wire the motor and other electricals such as solenoid valves and
temperature switch to the proper voltage and amperage as indicated
on the nameplate of each component being wired. Turn the booster
by hand after wiring is completed to determine that there are no
obstructions and if the booster turns freely; then momentarily start
the booster to check the direction of rotation. The illustration on
page 2 shows direction of air flow in relation to rotor rotation. The
air flow direction can be reversed by reversing the appropriate
motor leads.
OPERATION
Starting the Pump
Check the oil for proper level at both ends of the booster. Add or
drain oil as necessary to bring the oil to the correct level. See Figure
1. Too much oil particularly on the gear end can result in excessive
heat generation. Too little oil will possibly result in failure of the
timing gears, bearings, and mechanical seals.
Start the backing pump. When pressure is reduced sufficiently, start
booster pump. A pressure switch can be installed to start the
booster at a predetermined pressure. If the booster is water cooled,
turn on the cooling water when the booster is started. Adjust the
water flow so that the discharge water temperature is no more than
lukewarm (70° to 80° F).
Operating
The upper temperature limits for booster pump operation are
between 350° and 375° F measured in the exhaust gas stream with a
thermocouple. When this temperature limit switch is installed, as
the temperature exceeds the predetermined temperature, the booster
motor will stop and cannot be restarted until the temperature drops
below the trip setting of the temperature switch.
NOTE:
These upper limits are not for continuous operation.
Consult Kinney for detailed information or assistance.
CAUTION:
Use of a thermowell insulates the thermocouple.
Invalid and delayed reading will result. This can result in
ineffective protection devices.
Stopping the
Booster
CAUTION:
Venting the booster to pressures above cut-in while
running can damage the booster.
Stop the booster by turning off the motor. Isolate the booster
from the vacuum system and vent the booster to atmosphere.
Turn off the cooling water if water cooled. Stop the backing
pump. Refer to component instruction manual.
