Abstract
The utility model relates to a double strike type hydroturbine which consists of a water inlet, a water outlet, a pilot chamber, a shell of a draft tube, a principal shaft, a bearing, a base which can support the shell and an impeller sleeved on the principal shaft. The impeller is installed in the shell. Wherein, the pilot chamber is arranged on one profile of the shell, and the draft tube is arranged on an opposite profile to the pilot chamber in the shell. The hydroturbine also has a vortex cavity which is arranged on the other two profiles of the shell and between the water inlet and the water outlet. The utility model is suitable using in reformation of traditional cooling tower with the aim of improving efficiency of the hydroturbine and adapting to usage of the cooling tower in weak water supply.
Description
Technical field
The utility model belongs to refrigeration air-conditioner plumbing technical field, particularly a kind of general hydraulic turbine for cooling tower.
Background technique
Existing cooling tower generally adopts motoring blower fan exhausting, and its shortcoming is that noise is big, power consumption is high, and the year electricity charge that motor consumed are equivalent to purchase an expense that new cooling tower is required.For this reason, the inventor has designed a kind of cooling tower water turbine to replace the motor and the retarder of existing cooling tower, sees the CN2530233Y China utility model patent specification of bulletin on January 8th, 2003.In this patent, owing to disposed casing at the impeller place, when current through-flow impeller, can form eddy current in the current main flow both sides that flows to the outlet area from water intake, the zone and the outlet area of this swirl flow mix, make water outlet and eddy current produce mutual turbulence effect, hinder the acting of current, thereby reduced the efficient of water turbine.In addition,, make into water resistance increase, also can reduce the utilization efficiency of water turbine owing in the flume of inlet area, be provided with guide plate and branching block.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art, a kind of double click type frog song shaped water turbine is provided, this double click type frog song shaped water turbine can reduce water resistance, improves the efficient of water turbine, thereby can be applicable to better that cooling tower uses under less head situation.
The technological scheme that the utility model adopted is, a kind of double click type frog song shaped water turbine, it comprises the casing, main shaft, the bearing that have water intake, water outlet, flume and draft tube, be used to support the base of casing and be set on impeller on the main shaft, impeller is placed in the casing, wherein, flume is arranged on a side of casing, and draft tube is arranged on the casing opposite side relative with flume; This water turbine also comprises and is arranged on all the other both sides of casing and the vortex cavity between water intake and water outlet.
The utility model is by being provided with vortex cavity in the current main flow direction both sides that flow to water outlet from water intake, thereby reduced the interference of eddy current to water outlet, improved the efficient of water turbine, makes water turbine running balance, prolonged the working life of water turbine; On the other hand, also make to adopt the cold effect of cooling tower of the present utility model not to be subjected to what influence of water flow, all-the-time stable is in the optimum state.
Description of drawings
Fig. 1 is the structural representation of double click type frog song shaped water turbine of the present utility model;
Fig. 2 is the sectional view along A-A line among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1 and Fig. 2, double click type frog song shaped water turbine of the present utility model comprises casing 1, main shaft 2, bearing 3, impeller 4 and is used to support the base 5 of casing 1 that impeller 4 is set on the main shaft 2.Casing 1 is provided with flume 11, water intake 12, vortex cavity 13, water outlet 14 and draft tube 15.The size of water intake 12 and water outlet 14 should with the rapid-result ratio of feed water flow.Flume 11 is introduced water intake 12 with current.Flume 11 is arranged on a side of casing 1, is enclosed to put by coaming plate 112 to form, and coaming plate 112 plays the effect of guide plate, makes the current that flow into water intake 12 have the flow direction of the blade of impeller 4 not being had bump.In flume 11, cancelled guide plate of the prior art and branching block, avoided increasing because of the caused water resistance of guide plate and branching block is set.Draft tube 15 is arranged on the opposite side of the casing 1 relative with flume 11, is enclosed to put by coaming plate 152 to form, and the current that flow out from water outlet 14 flow to water distribution system through draft tube 15.Respectively be provided with a coaming plate 132 in all the other both sides of casing 1, coaming plate 132 is connected as a single entity with casing top plate 1a and inferior surface of machine case plate 1b, constitutes vortex cavity 13.Vortex cavity 13 is positioned at the both sides that flows to the current main flow direction of water outlet 14 from water intake 12, and its space and shape should satisfy the space and the shape of the eddy current that the overcurrent current are generated.Vortex cavity 13 is not communicated with mutually with flume 11 and draft tube 15.For eliminating noise, preferably, the hole as the pit shape is set on the wall of the chamber of vortex cavity 13.Impeller 4 is placed in the casing 1, and general direction of intaking on the radial plane of impeller 4 and water outlet general direction are on a diameter line.The number of blade of impeller 4 is 6 to 19, even more.
Below in conjunction with said structure of the present utility model working procedure of the present utility model is done a description.Hot water enters from water intake 12 through flume 11, cuts and hits impeller 4, cuts the geometrical shape of hitting the impeller water column and the geometrical shape of impeller intake and intersects.When water inlet through-flow impeller 4, can form eddy current in the current main flow both sides that flows to water outlet 14 from water intake 12, enter interior flowing water flow of vortex cavity and air and can produce pressure above-mentioned current main flow, this pressure helps to reduce the interference of eddy current to the current main flow, thereby has improved the efficient of water turbine.Current main flow through-flow impeller 4 makes impeller 4 drive the blade rotation after water outlet 14 enters draft tube 15, and whole flow process is happy, does not have the bump resistance.
Technical characterstic of the present utility model and beneficial effect are as follows:
1, energy savings is compared with the power consumption of the cooling tower that adopts motor, saves 100%.
2, noiseless, noise are the outstanding environmental protection indexs of cooling tower, and volume is little during the utility model running Trickle noise in tower satisfies environmental requirement.
3, be applicable to all cooling towers are transformed.
4, safety, cooling tower motor have the risk of spark blast, and the utility model has increased the Security of running environment.
5, simple in structure, maintenance is checked convenient.
6, the cold effect of cooling tower is not subjected to what influence of water flow, is in the optimum state all the time.
7, water turbine running balance, long service life.
Primary condition of the present utility model is flow and head, and cooling tower necessarily possesses into tower water flow and hydraulic pressure in actual applications, and water flow and hydraulic pressure can convert the air horsepower of impeller to, general all can satisfy condition of the present utility model.
Double click type frog song shaped water turbine of the present utility model not only can be used for cooling tower, and can be used for technical fields such as hydroelectric power.
