MTH Bearing Monitors take the guess work out of operating a canned motor
pump. They continuously monitor the direction of rotation and critical
running clearances between the stator and the rotor.
This bearing monitor system not only monitors the running clearance but
also indicates bearing condition. This allows the operator to plan in
advance for pump maintenance.
The bearing monitor operates on the principle of induced voltage. A magnetic
field is created in the monitor coils by the current flowing through the
stator winding. When the rotor is perfectly centered in the stator, the
magnetic fields are essentially concentric and balanced. When bearing
wear or unequal running clearance occurs, and the rotor drifts off center,
the flux created by the imbalance in the magnetic fields induces a voltage
in the monitor coils. This voltage is displayed on the monitor volt meter
as an indication of bearing condition. The meter is mounted on the pump
terminal box as standard, but is also available in a remote panel mount
package by customer request. |
