AUTOMATIC OPERATION TYPE WATER CHANNEL SUBMERGED PUMP

Japanese Patent JP2015145626

A

PROBLEM TO BE SOLVED: To provide an automatic operation type water pump channel submerged pump showing a superior heat radiation at a control circuit even if component elements constituting the control circuit is arranged within a limited space such as a head cover where generated heat of a motor is easily influenced.SOLUTION: This invention is constituted in such a way that a command processing part 12 for transmitting, as a command, a command signal of an appropriate control state on the basis of a detected signal of a water level detector for detecting a water level arranged in a pump main body 1; an opening or closing signal supplying control part 13 for supplying a signal to two or more non-contact type electronic power devices for controlling opening or closing supplying of power to a motor 8 with a command signal from the command processing part 12; a connection part 15 for connecting a power force and a control power supply; and a control unit 18 mounting a transformer 16 for stepping down the power supply voltage to a control voltage, the non-contact type electronic power device or the like on a heat sink 17 aiming at radiation heating are stored in a head cover 19 of a motor pump main body.
