一种轻便的卸车管道泵A lightweight unloading pipeline pump

技术领域technical field

本实用新型属于屏蔽泵技术领域，具体为一种轻便的卸车管道泵。The utility model belongs to the technical field of canned pumps, in particular to a portable unloading pipeline pump.

背景技术Background technique

屏蔽泵的工作原理与普通离心泵相同，靠叶轮旋转产生的离心力输送介质。结构上与离心泵不同，屏蔽泵电机与叶轮同轴一体，不需要联轴器连接，并且将动密封转化为静密封，用屏蔽套将转子与定子与输送介质隔离开，做到无泄漏。但由于屏蔽泵输送的介质具有强腐蚀性，所以对轴承提出了很高的要求，屏蔽泵采用具有石墨、碳化硅材质的滑动轴承，价格昂贵。The working principle of the canned pump is the same as that of the ordinary centrifugal pump, and the medium is conveyed by the centrifugal force generated by the rotation of the impeller. Different from the centrifugal pump in structure, the motor of the canned pump is coaxial with the impeller, no coupling is required, and the dynamic seal is converted into a static seal. However, due to the strong corrosiveness of the medium conveyed by the canned pump, high requirements are placed on the bearing. The canned pump uses sliding bearings made of graphite and silicon carbide, which are expensive.
