Abstract
The invention relates to a submerged pump adopting a squirrel-cage type middle elastic support. A shell sleeve of the submerged pump is divided into an upper shell sleeve and a lower shell sleeve, and the squirrel-cage type middle elastic support is arranged between the upper shell sleeve and the lower shell sleeve. Because the submerged pump has a structure of a slender shaft rotor system, and compared with the bending amplitude of a slender shaft, the bending moment born by a guide bearing has greater influence on the dynamic property of the rotor system. The middle elastic support of the submerged pump can effectively reduce the bending moment born by the guide bearing and the bending amplitude of the slender shaft, thus the vibration of the slender shaft rotor system of the submerged pump is controlled and the dynamic property of the slender shaft rotor system is improved.
