Abstract

The utility model discloses a cooling tower water power machine, which belongs to the technical field of cooling tower auxiliary equipment and is mainly characterized technically in that the cooling tower water power machine comprises a casing body with a water inlet and a water outlet, a covering body with a spray nozzle at a certain inclined angle is arranged inside the casing body, and a main shaft with a vane wheel is disposed inside the covering body. As a further improvement of the cooling tower water power machine, the vane wheel includes 5-17 vanes. The main shaft is connected with a power input shaft of a cooling tower, and water flow enters the covering body through the spray nozzle on the covering body after entering the casing body through the water inlet. Then eddy current whirling along a fixed direction is formed inside the covering body, and the eddy current pushes the vane wheel to rotate, thereby driving the main shaft to rotate. Consequently, as the excess pressure of the cooling tower is used for driving a fan to rotate without using an electric motor to supply power, the cooling tower water power machine can save electric energy and have low noise, uniform windspeed of the fan, fine cooling effect and strengthened safety of operation and maintenance of the cooling tower.

Description

Used for cooling tower hydrodynamic force machine

Technical field

The utility model belongs to cooling tower supplementary equipment technical field, relates in particular to a kind of used for cooling tower hydrodynamic force machine.

Background technique

Cooling tower is more and more wider in the application of industrial fields such as chemical industry, the cooling tower that uses adopts the motoring blower fan to carry out heat exchange mostly at present, the cooling tower of said structure is owing to adopt motoring to have following defective: one, and noise is big, the blower fan wind speed is inhomogeneous, cooling effect is poor; They are two years old, wasted the energy, its three, cooling tower is worked under high-risk condition, the potential risk that electric leakage is hurted sb.'s feelings, spark explodes is arranged, its four, motor weight is big, need to be equipped with speed reducer, and all need motor and speed reducer are safeguarded every year, when installing and overhaul, high-rise working needs lifting, has increased the operation of cooling tower, the cost of maintenance.

The model utility content

The technical problems to be solved in the utility model just provides that a kind of noise is little, the blower fan wind speed evenly, good cooling results, the used for cooling tower hydrodynamic force machine of safe, saving power that makes the operation of cooling tower and maintenance.

For addressing the above problem, the technological scheme that the utility model used for cooling tower hydrodynamic force machine adopts is: comprise the housing that has water intake and water outlet, in described housing, be provided with the cover body that has several inclination several angle nozzles, in described cover body, be provided with the main shaft that has impeller.

Its additional technical feature is:

Described impeller comprises 5-17 sheet blade.

Used for cooling tower hydrodynamic force machine provided by the utility model compared with prior art, have the following advantages: one, owing to comprise the housing that has water intake and water outlet, in described housing, be provided with the cover body that has several inclination several angle nozzles, in described cover body, be provided with the main shaft that has impeller, after current enter housing by water intake, nozzle on cover body enters cover body, in cover body, form along the eddy current of fixed-direction rotation, eddy current promotes wheel rotation, rotates thereby drive main shaft, and main shaft is connected with the power input shaft of cooling tower, like this, utilize the cooling tower overbottom pressure to promote fan and rotate, not needing provides power with motor, has saved electric energy, noise is little, the blower fan wind speed is even, good cooling results makes the operation of cooling tower and the Security of maintenance strengthen; Its two because described impeller comprises 5-17 sheet blade, make the utilization of structure and flow energy reach optimum efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model used for cooling tower hydrodynamic force machine;

Fig. 2 is the cross section structural representation of cover body.

Embodiment

Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model used for cooling tower hydrodynamic force machine.

As depicted in figs. 1 and 2, the utility model used for cooling tower hydrodynamic force machine comprises the housing 1 that has water intake 2 and water outlet 3, be provided with the cover body 4 that has several inclination several angle nozzles 5 in housing 1, the number of nozzle 5 can be set according to the diameter of cover body 4.In cover body 4, be provided with the main shaft 7 that has impeller 6.Main shaft 7 is connected with the power input shaft of cooling tower, after current entered housing 1 by water intake 2, the nozzle 5 on cover body 4 entered cover body, formed in cover body 4 along the eddy current of fixed-direction rotation, eddy current promotes impeller 6 and rotates, rotate thereby drive main shaft 7, like this, utilize the cooling tower overbottom pressure to promote fan and rotate, not needing provides power with motor, saved electric energy, noise is little, the blower fan wind speed even, good cooling results, makes the operation of cooling tower and the Security of maintenance strengthen.

For the quantity that makes the utilization of structure and flow energy reach the blade 8 on the optimum efficiency impeller 6 is 6, certainly, the quantity of blade 8 can be any sheet of 5-17.

The foregoing description is just to explanation of the present utility model, and therefore, protection domain of the present utility model not only is confined to the foregoing description, as long as structure is identical with the utility model used for cooling tower hydrodynamic force machine, just drops on the scope of the utility model protection.
