Abstract
PURPOSE: To prevent bad influence caused when the rotary shaft moved over the setting position, by providing a slip ring on the rotary shaft and detecting the movement of rotary shaft by means of abnormal balancing detecting circuit.
CONSTITUTION: When the balancing disc 9 and receiving sheet 10 are abrased to move the rotary shaft 5 to suction side more than allowable amount, the slip ring 14 contacts with a contactor thus to turn on the limit switch 15. Consequently the abnormal balancing detector circuit 24 is actuated to produce a detection signal while alarm circuit 24 produces abnormal balancing detection signal thus to function alarm circuit or pump stopping circuit, bad influence such as contact between the impeller 4 and the casing 1 can be prevented.
