6.2 START-UP CHECKLIST
We recommend that these startup procedures be followed in sequence and checked off ( ) in the
boxes provided in any of the following cases:
• During initial installation
• After any shutdown period
• After maintenance work has been performed
• After booster has been moved to a new location
DATES CHECKED:
Check the unit for proper lubrication. Proper oil level cannot be over-emphasized.
Refer to the
Lubrication
section. Please see
Recommended Lubricants
for information
on acceptable lubricants for your product.
Check V-belt drive for proper belt alignment and tension.
Carefully turn the rotors by hand to be certain they do not bind.
WARNING
Disconnect power. Make certain power is off and locked out before touching
any rotating element of the booster, motor, or drive components.
“Bump” the unit with the motor to check rotation (counter-clockwise [CCW] when
facing shaft) and to be certain it turns freely and smoothly.
Start the unit and operate it for 30 minutes at no load. During this time, feel the
cylinder for hot spots. If minor hot spots occur, refer to the
Troubleshooting
chart.
Apply the load and observe the operation of the unit for one hour.
If minor malfunctions occur, discontinue operation and refer to the
Troubleshooting
chart.
6.3 STARTING
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 4. 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 [21° to 26° C]).
6.4 OPERATING
The upper temperature limit for booster pump operation is 375° F (190° C)
measured in the exhaust gas
stream with a low mass 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.
DANGER
The booster is not intended to be used with explosive products or in
explosive environments.
