Abstract
The invention relates to a shield electric pump for conveying media easy to solidify and crystallize. The shield electric pump comprises a machine case, a stator and a rotor. The rotor is installed through a front bearing pedestal and a rear bearing pedestal which are arranged at the two ends of the machine case respectively. The stator is coaxially arranged in the machine case in a sleeved mode. The rotor protrudes and extends out of the front bearing pedestal and is fixedly connected with an impeller. The impeller is covered with a pump body, and the pump body and the machine case are fixed in a sealed mode. The side end of the pump body is provided with a feed port communicated with a pump cavity of the pump body. The upper end of the pump body is provided with a discharge port communicated with the pump cavity. An air gap passage is formed between the stator and the rotor. The position, corresponding to the stator, of the outer wall of the machine case is fixedly sleeved with a water jacket. Two steam jackets are fixedly arranged on the outer side of the pump body and the outer side of the rear bearing pedestal respectively in an attached mode. Through the arrangement of the steam jackets on the two sides and the water jacket, when solidified or crystallized media remain in the shield electric pump, the temperature of the shield electric pump can be raised by connecting steam to the shield electric pump so that the solidified or crystallized media can be molten; consequently, the problem that the media are solidified or crystallized is effectively and timely solved, and damage caused by blockage is avoided.
