Abstract
The utility model relates to a water turbine runner fixing device. The water turbine runner fixing device comprises a runner of a water turbine. The water turbine runner fixing device is characterized in that a fixing device on the bottom of the runner is a runner cone. The water turbine runner fixing device is simple in structure and convenient to use, the defects of existing runner fixing devices are overcome, work efficiency is improved, the server life of the water turbine runner fixing device is prolonged, and cost is saved.
Description
Technical field
The utility model relates to a kind of rotary wheel of water turbine fixing device.
Background technique
Water turbine for cooling tower is in the middle of practical process at present, and the runner fixing device is designed to nut, is cylindrical, and block water stream flows out water turbine through behind the runner, causes the part hydraulic loss, the water turbine working efficiency of impact.This situation requires water turbine to reach higher efficient, and cooling tower just can efficiently move.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of rotary wheel of water turbine fixing device is provided, changes the structure of conventional rotor fixing device, improve the efficient of water turbine.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of rotary wheel of water turbine fixing device, comprise it is characterized in that the runner of water turbine, and the fixing device of runner bottom is draft cone.
Described draft cone is conical, and the draft cone bottom is for being horizontally disposed with bolt, and bolt is fixed on the runner bottom with draft cone.
The tapering of described draft cone is identical with the terminal tapering of runner pressed on ring.
Bolt fixed mode is simple and easy to dismounting and arranges, the design angle of draft cone can be 100 ~ 130 ° identical with the terminal tapering of runner pressed on ring, in runner work, rotate simultaneously with it, the water flows gently flows out water turbine in guiding, and then the efficient of raising water turbine.
The beneficial effect that the utility model has is: simple in structure, easy to use, overcome the shortcoming of existing runner fixing device, and improved its working efficiency, increase working life, save cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Arrow is water (flow) direction among the figure;
Among the figure: 1, runner; 2, draft cone; 3, the runner pressed on ring is terminal; 4, bolt.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
Rotary wheel of water turbine fixing device as shown in Figure 1 comprises the runner 1 of water turbine, and the fixing device of runner 1 bottom is draft cone 2.Draft cone 2 is conical, and draft cone 2 bottoms are for being horizontally disposed with bolt 4, and bolt 4 is fixed on runner 1 bottom with draft cone 2.The tapering of draft cone 2 is identical with terminal 3 taperings of runner pressed on ring.Bolt 4 means of fixation are simple and easy to dismounting and arrange, the design angle of draft cone 2 can be 100 ~ 130 ° identical with terminal 3 taperings of runner pressed on ring, in runner 1 work, rotate simultaneously with it, the water flows gently flows out water turbine in guiding, and then the efficient of raising water turbine.
