Easily overhauled micro full mixed flow horizontal water-turbine generator set

Abstract

The invention relates to an easily overhauled micro full mixed flow horizontal water-turbine generator set which solves the problem of overhauling and replacing a damaged pushing-guiding bearing of the set effectively without detaching any large parts of the water-turbine generator set. A generator and a water turbine are mounted on a base; a rotor shaft of the generator is transversely and concentrically connected to a rotary shaft of the water turbine through a middle connecting structure; a generator side shaft coupling device and a water turbine side shaft coupling device are mounted at two ends of the middle shaft; the generator side shaft coupling device connects the middle shaft to the rotary shaft of the generator concentrically; the water turbine side shaft coupling device connects the middle shaft to the rotary shaft of the water turbine concentrically; a main shaft seal is mounted at the connection part of the rotary shaft and the shell of the water turbine; one end, close to the middle shaft, of the generator shaft is mounted on a pushing-guiding bearing on the shell and is connected to the middle shaft through the generator side shaft coupling device; the rotary shaftextending out the other side of the shell of the generator is mounted in a guiding bearing on the shell of the generator; and a water turbine guiding bearing is mounted on the rotary shaft between thewater turbine side shaft coupling device and the water turbine.

Description

technical field [0001] The invention relates to power generation equipment, in particular to a miniature self-contained mixed-flow horizontal hydroelectric generating set which is easy to repair. technical background [0002] Hydrogenerator is a commonly used power generation equipment. Although the 2-fulcrum rolling bearing integrated Francis hydrogenerator set currently used has the advantages of simple structure, small size, no need for cooling water for the bearing, and quick on-site installation, it is used in small and micro hydropower stations. Get widely used. But this unit has a serious deficiency, is exactly difficult, bother to change one group of derivation-guide bearings that are contained on the generator during unit overhaul. [0003] The original whole-package Francis turbine generator set adopts a 2-support structure, the turbine and the generator share the same shaft, the generator uses end rolling bearings, the turbine end is a pusher-guide bearing, and t...

AI Technical Summary

Problems solved by technology

After the bearing is replaced, since the generator is moved, the axis of the unit must be readjusted when reinstalling, which makes the maintenance time-consuming and laborious, and becomes a difficult problem in the maintenance of the unit
