Abstract:
1. A starting system for a pump comprising: a motor for driving the pump; an electric source connected to the driving motor for supplying the driving motor with electric power; a selector switch located between the driving motor and the electric source for reversing polarity of the electric power supplied from the electric source to the driving motor while selectively connecting the driving motor to the electric source and disconnecting the driving motor from the electric source; a starter sensor provided with the driving motor for sensing whether or not the driving motor has been started; a temperature sensor provided for sensing a temperature; and a control unit connected to the electric source, the selector switch, the starter sensor and the temperature sensor, wherein the control unit operates the selector switch so as to repeatedly give the driving motor indications of reverse rotation and normal rotation in a case where the starter sensor does not sense that the driving motor has been started even if the control unit operates the selector switch so as to give the driving motor the indication of normal rotation in a state where the temperature sensed by the temperature sensor is a preset temperature or below.
