| Abstract: | Aiming at the larger surplus capacity of the heat supply network circulating pump in Xixia Thermal Power Generation Company, caused heavy throttle loss, higher delivery lift of the pump and overload of the motor. According to the basic theory of the pump, fixed on improvement project of impeller turning technics for thermal grid circulating pump. The result shows that after improvement the throttle loss of the outlet valve of circulating pump and the load current of the motor decrease, the effects of energy saving and efficiency increasing are obvious. |
