摘要
PURPOSE: A preheating water circulating pump with a water leakage prevention member is provided to accommodate a tiny amount of preheating water being leaked to outside of a pump case and to selectively evaporate the preheating water, thereby secluding an inflow of the preheating water into the inside of a motor.;CONSTITUTION: A preheating water circulating pump(10) comprises a motor assembly(12), an impeller(14), a pump case(16), and a water leakage prevention unit. The motor assembly generates torque with power supplied from outside. The impeller is axially joined to a motor shaft(13) of the motor assembly, thereby connected to the motor assembly. The pump case comprises the impeller in inside. The pump case guides a flow of preheating water. The water leakage prevention unit collects steam discharged to outside of the pump case between the pump case and the motor assembly. The water leakage prevention unit selectively evaporates the discharged steam.;COPYRIGHT KIPO 2013
