Embodiment 1

[0066] The hoisting and suspension snap ring of the runner of the axial flow paddle type water turbine in this embodiment is composed of two arc-shaped snap ring bodies connected end to end to form a ring. Screw holes; both ends of the clasp body are provided with inner digging cavities, and the inner digging cavities are provided with connectors connecting the two clasps. The connectors in this embodiment are bolts. The principle of this embodiment is to process a ring groove on the outer edge of the cylinder head of the runner servomotor as a clamping ring and the force-bearing area of ​​the runner suspension; to process screw holes on the flange surface of the lower part of the diversion cone to snap ring, so that it is combined with the diversion cone. As a matter of course, the inner diameter of the snap ring should match the ring groove of the cylinder head of the runner servomotor; in order to connect the snap ring with the guide cone, when the snap ring snaps into the ...

Embodiment 2

[0069] The hoisting and suspension snap ring for the runner of the axial-flow paddle-type water turbine in this embodiment includes a three-lobed arc-shaped snap ring body, and the snap ring body is evenly distributed with screw holes for connecting the snap ring body and the turbine diversion cone. The use method of this embodiment is to process a ring groove on the outer edge of the cylinder head of the runner servomotor as a snap ring to snap into and the force-bearing area of ​​the runner suspension; to process screw holes on the flange surface of the lower part of the diversion cone to The clasp ring is combined with the diversion cone; when in use, first snap the three clasp bodies into the ring groove of the cylinder head of the runner servomotor, and then use the screw hole to guide the clasp ring and the turbine cone. As a matter of course, the inner diameter of the snap ring should match the ring groove of the cylinder head of the runner servomotor; in order to conne...

Embodiment 3

[0071] The hoisting and suspension clasps of the runner of the axial flow paddle type water turbine in this embodiment are formed by four-lobed arc clasps connected from end to end to form a ring, and the clasps are evenly distributed with holes for connecting the clasps and the diversion cones of the water turbine. Screw holes; both ends of the clasp body are provided with inner digging cavities, and the inner digging cavities are provided with connectors connecting the two clasps. The connectors in this embodiment are bolts. The principle of this embodiment is to process a ring groove on the outer edge of the cylinder head of the runner servomotor as a clamping ring and the force-bearing area of ​​the runner suspension; to process screw holes on the flange surface of the lower part of the diversion cone to snap ring, so that it is combined with the diversion cone. As a matter of course, the inner diameter of the snap ring should be compatible with the ring groove of the cyli...

Abstract

The invention discloses an axial-flow rotary paddle turbine runner hoisting and suspension snap ring, which is used for overcoming the shortcomings of the existing axial-flow paddle-turbine runner hoisting and suspension methods, such as numerous procedures and inconvenient operation. The present invention includes at least two arc-shaped snap ring bodies, and the snap ring bodies are uniformly distributed with screw holes for engaging the snap ring bodies with the diversion cone of the water turbine. The invention has the advantages of simple structure, no need to open tooling holes on the base ring and the blade body, and no need to process the concave ring groove or the convex ring belt on the main shaft, so the operation is very simple and convenient, many processes are saved, and the improvement is greatly improved. The installation and maintenance work efficiency of the unit is improved.

Description

technical field [0001] The invention belongs to the field of axial-flow paddle-type water turbines, and specifically relates to a method for hoisting and suspending the runners of axial-flow-paddle-type water turbines. The invention is applicable to all axial-flow water turbines, especially suitable for existing units before transformation The hoisting and suspension of the runner is realized by the foundation ring, and the axial-flow turbine unit whose number of blades changes after transformation. Background technique [0002] There are two main ways of hoisting and suspending the runners of the existing turbines. One is to open the joint holes on the base ring and the blades of the runner blades at the same time, which are used to install the pull rod tools for hanging the runners (mainly for large axial flow turbines). The second is to process concave ring grooves or raised ring belts on the main shaft of the turbine, and at the same time use the screw holes of the beari...
