4. Starting the pump.
Once the pump is primed, start the pump by turning on the power to the
motor as instructed in the motor manual and follow this recommendation:
• Check for pressure leaks, make an immediate visual inspection of
the pump and suction piping.
• Upon the pump reaching full operating speed, begin to open the
discharge gate valve slowly until complete system flow is achieved.
• The discharge pipe should also be checked for pressure leaks.
• If there are pressure gauges on the pump, record pressure readings
to use as a reference in the future
• Also make sure the pump is falling within the parameters of the
performance curve.
• Check and record Voltage, amperage per phase, and
kilowatts.
Voltage regulation.
While the motor will operate satisfactorily under these voltage and
frequency variations, such operation may not be in accordance with
the standards established for operation in underrated conditions:
•
Variation in the voltage may not exceed ± 10% the rating
specified on the motor data plate.
•
Frequency variation may not exceed ± 5% the rating
specified on the motor data plate.
•
The sum of the voltage and frequency variation may not
exceed ± 10% the motor rating while the frequency variation
does not exceed ± 5%.
WARNING.
If a pump is operated without an approved coupling guard in
place, it may result in injury to personnel operating the
pump. Coupling guard should be installed on flexible
coupled units.
