Description
Technical field
The utility model relates to water turbine, cooling tower, particularly a kind of water turbine and adopt the cooling tower of this water turbine.
Background technique
Existing water turbine is all by setting into water flow passage, eddy chamber and water outlet, relies on the impact force of current to drive the runner in eddy chamber, thereby drives main shaft to rotate, and realizes power output.But, in actual use, but find existing water turbine because it exists the various defect youngsters that have much room for improvement to fail to reach best using effect.
The first, coordinate one and enter water flow passage because traditional water turbine mostly is water inlet, impact force is limited, causes the rotating speed of water turbine to be restricted, be difficult to reach at a high speed, and traditional water turbine to enter the angle of water flow passage and wheel blade also scientific and reasonable not.
The second, the eddy chamber of traditional water turbine is welded and fixed by coaming plate and upper cover, lower cover, becomes the entirety of shutting, so must be by cutting equipment by its rigid cutting open while causing maintenance or nursing.This structure being welded not only causes maintenance cost high, and is extremely easily damaging water turbine, uses because water turbine after cutting open through the rigid cutting of two to three times, is just again difficult to welding.
The 3rd, what traditional water turbine adopted is the built-in form of bearing, water seal, in the upper end of eddy chamber, water seal need to be set.This bearing, water seal embedding structure, once bearing or water seal damage, need whole water turbine to decompose, and cuts eddy chamber open, just can carry out replacing or the maintenance of bearing, water seal.
The 4th, current water turbine, in the time of flow pressure that water source head is not had more than needed, the pressure versus flow deficiency of water, can directly cause the reduction of runner rotating speed, is difficult to reach needed rotating speed, thereby affects the power output effect of water turbine.In the time that water turbine is used for cooling tower, above-mentioned defect can make water turbine in the time of hydraulic pressure and underfed, fails to reach rated speed, especially can not be suitable for the needs of large-tonnage cooling tower, once because rotating speed does not reach minimum requirements, cooling effect can not be guaranteed, can cause a series of pernicious impact.
As can be seen here, still there are many deficiencies in existing water turbine, and be urgently further improved on unitary construction.
