Abstract

The invention discloses a disassembling and assembling tool for a mixed flow horizontal water turbine. The disassembling and assembling tool comprises a spindle and rotary wheels and further comprises a pull rod; the pull rod is sleeved with a bushing, and a flange plate is fixedly connected to the bushing and detachably connected with the rotary wheels; and the pull rod and the spindle are coaxial and are detachably connected. According to the scheme, the rotary wheels can be prevented from shaking or deflecting, so that the rotary wheels always move in the axis direction of the spindle without shaking or deflecting in the process that the rotary wheels are lifted and installed on the spindle, the rotary wheels can be better positioned in the process of being assembled on or disassembled from the spindle, the situation that center holes of the rotary wheels collide with the surface of the spindle and is abraded can be avoided, the assembling or disassembling precision is higher, and the errors are smaller.

Description

technical field [0001] The invention relates to the field of water turbines, in particular to a disassembly tool for a mixed-flow horizontal water turbine runner. Background technique [0002] A Francis water turbine is a kind of existing hydroelectric power generation equipment, and its main structure includes a main shaft, a running wheel connected to the main shaft, and a water guiding mechanism arranged correspondingly to the running wheel. When the runner needs to be overhauled or replaced, the runner needs to be disassembled and installed. In the process of installing and dismounting the runner in the prior art, because the weight and volume of the runner are very large, the runner is usually disassembled by hoisting the runner by driving. However, because the runner is suspended during the disassembly process, it is very difficult to It is easy to shake, which makes disassembly and assembly very inconvenient, and it is easy to cause large disassembly deviation or dam...
