Items to check during equipment commissioning
①
Power supply
①
Electromagnetic switch capacity
②
Installation
③
Connection to the power supply
④
Correct switch connection
De-energization of any one line due to
the disconnection of a power line or
poor switch connection will cause
single-phase operation, and the motor
will burn.
②
Rotational
direction
Rotational direction matches the
arrow-marked plate.
When the motor rotation is in the
reverse, change the two power supply
lines for each other.
③
Operating
static pressure
and current
A pressure gage and an ammeter show
that the operating static pressure and
current are below the maximum
operating static pressure and current.
If pressure is above the maximum
operatic static pressure, provide a
bypass hole to let air out.
④
Operating status
No abnormal vibration or noise.
If any, please contact us.
Maintenance inspections
We recommend checking for any deterioration in insulation, and for abnormal vibration or noise every three
months. The motor bearing uses a sealed ball bearing requiring no lubrication. The grease life is roughly one
year, although it varies greatly depending on the operating environment.
