Abstract
The invention discloses a sinking pump automatic control device and a control method of the sinking pump automatic control device and relates to the technical field of sinking pump automatic control. The sinking pump automatic control device comprises a sinking pump, a water level limiting gauge, an alternating current contactor, a fuse protector, a time relay and a heat relay. The time relay is in series connection with a limiting switch of the water level limiting gauge. A coil of the alternating current contactor is in series connection with a delaying normally open contact of the time relay. After two series branches are connected in parallel, a normally closed contact of the heat relay and the fuse protector are in series connection between any firing line and a null line of a supply circuit of a three-phase alternating current motor of the sinking pump. A main contact of the alternating current contactor and a coil of the heat relay are in series connection in a supply loop of the three-phase alternating current motor. When a water level rises to the level higher than that of the water level limiting gauge, the limiting switch is switched off and the sinking pump starts to operate. When the water level drops to the level lower than that of the water level limiting gauge, the time delay starts to time, and the sinking pump stops operating after timing is end. The sinking pump automatic control device has the advantage of automatically controlling the sinking pump and is suitable for being used in basements with water seepage or water leakage.
