Abstract
Provided is a shield sleeve for a shield pump. The shield sleeve for the shield pump is characterized in that concave-convex ring-shaped structures are arranged at two ends of the shield sleeve, when the shield sleeve deforms after the shield sleeve is cooled or is heated, the concave-convex ring-shaped structures can produce displacement and deformation. A stator shield sleeve is composed of one end portion (8a) of the shield sleeve, the other end portion (8e) of the shield sleeve, a portion (8c) which is matched with a stator core in a tight press mode, a concave-convex ring-shaped structure (8b) which is adjacent to the end portion (8a) of the shield sleeve, and a concave-convex ring-shaped structure (8d) which is adjacent to the other end portion (8e) of the shield sleeve. Compared with the prior art, by improving the structure of the shield sleeve, the shield sleeve for the shield pump can effectively absorb rapid deformation of the shield sleeve caused by rapid temperature changes, solves the problem that the shield sleeve is damaged because of temperature changes of components of the shield pump are uneven, desynchronized and inconsistent, and can improve reliability and safety of operation of the shield pump.
