Abstract
The invention disclosed a tubular runner turbine vertical hydraulic static equilibrium device, and the tubular runner turbine vertical hydraulic static equilibrium device includes a bearing 1, a hanger 2 on the bearing 1, the hanger 2 having the connecting axis 3, the runner 9 through the flange 4 to connect with the connecting axis 3, the dispensing system 5 connecting the fuel tank 6, the fuel tank 6 equipped with convex spherical ball 7 and concave spherical ball 8. The invention has the following advantages: simple operation, safe and reliable, able to meet the requirements of large turbine static equilibrium experiments.
Description
Technical field
The present invention relates to the static balancing apparatus of tubular turbine runner, particularly vertical hydraulic static balancing apparatus for through flow turbine rotary wheel.
Background technology
Rotary wheel of water turbine is a rotary body, in manufacture process, after processing and assembling, certainly will have size, shape, the various errors in position, thereby produce the imbalance of weight.On the other hand, the critical part of forming runner is foundry goods mostly, the inhomogeneous weight imbalance that makes of the material of foundry goods, these all will cause runner in dynamic and static imbalance, out-of-balance force and moment are scratched power to the hydraulic turbine and generator generation, thereby cause unit vibration, simultaneously turbine guide bearing is produced the additional force of a rotation, unit operation stability is damaged.Therefore, the runner balance is significant, and concerning large-scale water turbine, the runner quality is big especially, the also corresponding increase of uneven weight, and balance is particularly important.The static equilibrium mode, use always vertical and horizontal two kinds, large rotary wheel all adopts vertical, promptly adopt the method for ball rolling pendulum on flat board, but this method has relatively high expectations to static state, the balance place should be more solid, after runner is put on the balance base, platform below the base and basis do not allow distortion, around the balance place bigger vibration can not be arranged, and a balance ball and a support should have higher intensity and hardness.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, and vertical hydraulic static balancing apparatus for through flow turbine rotary wheel a kind of simple to operate, safe and reliable is provided, and can satisfy large-scale water turbine static equilibrium experimental requirements.
Purpose of the present invention is achieved through the following technical solutions: vertical hydraulic static balancing apparatus for through flow turbine rotary wheel, it comprises bearing, suspension bracket is installed on the bearing, suspension bracket is provided with coupling shaft, web links to each other with coupling shaft by flange, oil supply system connects fuel tank, is provided with protruding spheroid and recessed spheroid in the fuel tank.
By top narration as can be seen, the present invention has the following advantages: simple to operate, safe and reliable, can satisfy large-scale water turbine static equilibrium experimental requirements.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure, the 1-bearing, 2-suspension bracket 2, the 3-coupling shaft, the 4-flange, the 5-oil supply system, 6-connects fuel tank, the protruding spheroid of 7-, the recessed spheroid of 8-, 9-web.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing: certain power station rotary wheel of water turbine is high about 3.5 meters, weight reaches 41 tons when doing static balancing test, adopt vertical hydraulic static balancing apparatus for through flow turbine rotary wheel to do static balancing test, it comprises bearing 1 vertical hydraulic static balancing apparatus for through flow turbine rotary wheel, suspension bracket 2 is installed on the bearing 1, suspension bracket 2 is provided with coupling shaft 3, web 9 links to each other with coupling shaft 3 by flange 4, oil supply system 5 connects fuel tank 6, is provided with protruding spheroid 7 and recessed spheroid 8 in the fuel tank 6.
Tubular turbine runner vertical hydraulic static balancing method, it may further comprise the steps: a, oil supply system 5 oil-feeds, between protruding spheroid 7 and recessed spheroid 8, form oil film, web 9 is held up slightly; B, web 9 utilize own wt to keep stationary state, can tilt to a certain direction during web 9 imbalances, and it is poor to measure each blade height; C, use the balancing weight balancing, reach the designing requirement equilibrium state up to web 9.
