AUTOMATIC OPERATION TYPE ONE CHANNEL SUBMERGED PUMP
Document Type and Number:
Japanese Patent JP2015025367
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an automatic operation type one channel submerged pump showing a superior heat radiation of a control circuit even in the case where some elements constituting the control circuit and the like are arranged in a space within a head cover, where influence of generated heat of a motor can be easily attained, and a limited space.SOLUTION: An automatic operation type one channel submerged pump comprises, in a head cover 19 of a motor pump main body: an instruction processing part 12 for transmitting an instruction signal of an appropriate control state on the basis of a detecting signal of a water level sensor for sensing a water level that is installed in a pump main body 1; an opening or closing signal feeding control part 13 for feeding a signal to two or more electronic power devices of non-contact point type controlling an opening or closing of feeding electricity to a motor 8 with the instruction signal from the instruction processing part 12; a connecting part 15 for connecting a power and control power supply; and a control unit 18 where a transformer 16 for dropping a power supply voltage to a control voltage, the non-contact point type electronic power devices and the like are installed on a heat sink 17 aiming at performing a heat radiation cooling.
