Abstract

The invention discloses a slurry-rotating-type turbine runner connecting rod pin limiting device. The slurry-rotating-type turbine runner connecting rod pin limiting device comprises a limiting part,an outer lug and an inner lug, wherein the outer lug and the inner lug are fixed to a turbine runner relay cylinder, connecting rod pins are assembled in pin holes of the outer lug and the inner lug,a clamping groove is formed in the outer lug, the lower portion of the limiting part is arranged in the clamping groove, the upper portion of the limiting part blocks the lower areas of the outer endfaces of the connecting rod pins, the limiting part is limited in the clamping groove through the connecting part and does not fall off, axial displacement force of the connecting rod pins is totallyborne by the limiting part and the clamping groove, and the connecting part does not bear the axial displacement force of the connecting rod pins. By means of the slurry-rotating-type runner connecting rod pin limiting device, the limiting part which is used for limiting axial displacement of the connecting rod pins is limited in the clamping groove through the connecting part, so that the axial displacement force in the working process of the connecting rod pins is completely borne by the limiting part and the clamping groove, the connecting part only achieves the effect of fixing the limiting part and does not bear the axial displacement force of the connecting rod pins, and the working safety and reliability of a slurry-rotating-type turbine runner are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water turbine design, and in particular relates to a limiting device for a runner connecting rod pin of a rotary paddle type water turbine. Background technique [0002] Due to assembly requirements, the connecting rod pin on the rotor servomotor cylinder of the rotary paddle type (axial flow type, tubular flow type) is generally designed as a stepped pin, which is small on the inside and large on the outside, and the connecting rod pin is assembled from the outside to the inside. During the operation of the unit, due to the influence of related components manufacturing, installation quality and centrifugal force, the connecting rod pin may move outward axially, endangering the operation safety of the unit. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a rotary paddle turbine runner connecting rod that can effectively limit the axial m...
