Controlling instrument for secondary pump in heat exchanging station

The invention discloses a controlling instrument for a secondary pump in a heat exchanging station. The controlling instrument comprises a secondary pump body, a high-area regulating valve, a low-arearegulating valve, a low-area plate type heat exchanger, a high-area plate type heat exchanger, a low-area secondary circulating pump, a high-area secondary circulating pump and a central controller ALK; one end of the secondary pump body is connected with the high-area regulating valve and the low-area regulating valve, and the high-area regulating valve is further connected with the low-area plate type heat exchanger and the high-area plate type heat exchanger; and the low-area plate type heat exchanger further outputs low-area water supply through the low-area secondary circulating pump. According to the controlling instrument for the secondary pump in the heat exchanging station, balance temperature supplying of all areas in the heat exchanging station can be achieved by using only onesecondary pump, the contr
