Abstract
The utility model discloses an efficient counterstroke mixed flow type water turbine for a cooling tower, which comprises a tail water pipe, wherein a seat ring is arranged at the upper end of the tail water pipe, a water guide blade is arranged in the seat ring, the upper end of the seat ring is provided with a cover plate, a main shaft is arranged in the center part of the seat ring, the lower end of the main shaft is provided with a rotating wheel, a scroll case is arranged at the outer side of the seat ring, the scroll case is arranged at one side of the seat ring in opposite direction of the seat ring axial line, the rotating wheel is in an integral structure, and a gear speed regulator is arranged at the outer side of the main shaft arranged on the cover plate. The efficient counterstroke mixed flow type water turbine for the cooling tower adopts the single scroll case, the weight of a machine body is reduced through the single side water inlet distribution, and the vibration of the water turbine is greatly reduced, so the tower body vibration and the noise during the movement are reduced to a minimum degree, and the work efficiency is higher.
Description
Technical field
The utility model relates to a kind of water turbine, relates in particular to a kind of water turbine for cooling tower.
Background technique
In prior art, the water turbine of the cooling tower of large scale industry hot water generally is with the double volute water turbine of intaking.On the one hand, the water turbine of this structure is provided with the spiral case of two-way water inlet at the seat ring center, be inversion symmetry and distribute, its installation dimension is excessive, and has increased intake pipe, cost is higher, increased water can loss, the increase of water turbine weight has also in a disguised form improved the design strength of water turbine, on the other hand, what this cooling tower water turbine core component adopted usually is the runner of solder type, and the blade of runner is not designing according to fluid mechanics of science, has increased the resistance of water, solder joint is in long-term running in addition, corrosion appears, in the time of serious, and the scolder that comes off, it is first-class that welding slags etc. can stop up the water spray of below, clearly, double volute water inlet structure efficient is low, and energy consumption is big, and construction is difficult, the cost height is safeguarded shortcomings such as inconvenience.
The model utility content
For addressing the above problem, the utility model provides a kind of used for cooling tower that can raise the efficiency efficiently to strike back Francis turbine.
The utility model has been taked following solution: a kind of used for cooling tower is efficiently strikeed back Francis turbine, comprise draft tube, described draft tube epimere is equipped with a seat ring, be provided with water guide blade in the described seat ring, described seat ring upper end is provided with cover plate, described seat ring center is provided with main shaft, and described main shaft lower end is provided with runner, and the described seat ring outside is provided with a spiral case; Described spiral case is with the side of seat ring axis reversed arrangement at seat ring; Described runner is an integral structure; The main shaft outside on the described cover plate is provided with the gear speed regulator.
The utility model adopts single spiral case water inlet structure, has reduced the weight of body, and tower body vibration when making operation and noise all drop to minimum, has reduced the loss of water energy, has reduced cost.

Embodiment
Counterattack Francis turbine as shown in Figure 1, 2, comprise a draft tube 1, described draft tube 1 upper end is equipped with a seat ring 2, be provided with water guide blade 3 in the described seat ring 2, described seat ring 2 upper ends are provided with cover plate 5, and a vertical main shaft 6 that inserts center in the ring is housed by bearing in the center of cover plate 5, and the runner 7 of an integral type is housed in main shaft 6 lower ends, be connected with spiral case 4 in seat ring 2 outsides, spiral case 4 adopts single spiral case water inlet.A gear speed regulator is installed in the epimere outside at main shaft 6.
Working procedure: when current when spiral case 4 enters water turbine, current are along with spiral case 4 directs into seat ring 2, the pilot flow by water guide blade 3 in the seat ring 2 is to runner 7 again, and promotion runner 7 rotates, arrange to draft tube 1 from the water that runner 7 comes out, discharge from draft tube 1 at last, main shaft 6 rotates with runner 7.
Claims (3)
1. a used for cooling tower is efficiently strikeed back Francis turbine, comprise draft tube, described draft tube epimere is equipped with a seat ring, be provided with water guide blade in the described seat ring, described seat ring upper end is provided with cover plate, and described seat ring center is provided with main shaft, and described main shaft lower end is provided with runner, it is characterized in that: the described seat ring outside is provided with a spiral case, and described spiral case is with the side of seat ring axis reversed arrangement at seat ring.
