Vertical suspended semi submersible vertical turbine pump impeller locking device

A vertical suspended semi submersible vertical turbine pump impeller locking device belongs to the technical field of chemical production equipment, comprising a locking back cap, characterized in that it further comprises a locking clamp fitted on the locking back cap, the locking clamp comprising a main body and a contact part, the main body and the contact part are integrally formed, the center of the end face of the contact part is provided with a circular convex platform, and a brake pin is provided on the circumference of the end face of the contact part. There are six strip-shaped holes in the circumferential axis of the main body, and the spacing between any two adjacent strip-shaped holes is the same. The height of the strip-shaped hole is two-thirds of the height of the main body, and the cross-section of the locking back cap is a regular hexagon. This technical method achieves axial and radial fixation of the impeller through a good fit between the locking clamp and the locking back cap, making the fixation more secure and effectively preventing the impeller from shaking during long-term operation and sudden start-up, thereby ensuring the long-term stability of the vertical suspended semi submersible vertical turbine pump.
