Abstract
This invention relates to a general water-turbine of a cooling tower including a case with inlet and outlet, a mainshaft, bearing and a blade wheel mounted on the mainshaft, a delivery zone in the case. The invention eliminates motor and reducing device. The blade wheel is set at the inlet, its intale direction on the sagitted plane is on the same line with the delivery, and strikes the blade wheel in water post geometric shape crossing that of the inlet and slowly releases at the delivery zone after breaking through the impeller to rotate blades and flow out through the outlet.
Description
Technical field
The invention belongs to refrigeration air-conditioner plumbing technical field, particularly a kind of general hydraulic turbine for cooling tower.
Background technique
Existing cooling tower generally needs the blower fan exhausting, and blower fan is by motoring, and the related retarder that has still is difficult to eliminate the mechanical noise that is produced.Moreover, the electricity charge that motor consumed, its running can be purchased the cooling tower of a respective handling water yield in 1 year.
Existing water turbine then is not suitable for cooling tower, because the intake pressure of cooling tower is generally less than 0.1MPa, the required hydraulic pressure of various water turbine is had relatively high expectations mostly.The structural type of axial flow and Francis turbine difficulty is applicable to cooling tower, tubular turbine can structurally be suitable for owing to having the characteristics that flow is big, pressure head is little, but its vibration cause usually makes noise be difficult to eliminate, and efficient is lower, does not usually satisfy the requirement that old old cooling tower cancellation motor when transforming does not increase pump head.
Summary of the invention
Task of the present invention provides a kind of improved general hydraulic turbine for cooling tower, has cancelled motor and retarder, has solved the existing in prior technology problem, need not increase lift again by the desired pump head of existing cooling tower, as power, economize on electricity noiseless with water.
Technological scheme of the present invention is as follows:
A kind of general hydraulic turbine for cooling tower, it comprises the casing that has water intake and water outlet, main shaft, bearing and be placed in impeller on the main shaft, it has cancelled motor and retarder; Be provided with the outlet area in the described casing; Described impeller is arranged on the water inlet, general direction of intaking on the radial plane of impeller and water outlet general direction are on a diameter line, water inlet is cut and is hit impeller, cutting the geometrical shape of hitting the impeller water column and the geometrical shape of impeller intake intersects, behind the water inlet through-flow impeller at the outlet area slowly-releasing, make impeller drive the blade rotation, after the water outlet outflow.
Cooling tower adopts general hydraulic turbine for cooling tower of the present invention, has cancelled the motor and the retarder of existing cooling tower, is replaced by general hydraulic turbine for cooling tower, as power, promotes general hydraulic turbine for cooling tower with hot water, and the impeller blade draws water.Characteristics of the present invention are no power consumptions, and noiseless is simple and effective, and the power consumption than existing cooling tower when running well saves 100%, are applicable to all cooling towers, and can transform all old towers, are mounted on the front of water-dispensing device in the circulating water route.
Technical characterstic of the present invention and beneficial effect are as follows:
1. energy saving is compared with the power consumption of existing cooling tower, saves 100%.
2. noiseless, noise is the most outstanding environmental protection index of cooling tower, volume was less than the environmental protection index requirement when the present invention was turned round.
3. be applicable to that improved effect is the same with the new technology of whole tower to the transformation of all turriforms such as existing cooling tower.
4. the gas-water ratio all-the-time stable of cooling tower is in the optimum state, and cold effect is best.
5. vibration reduces, and has prolonged working life.
6. safety, the cooling tower motor can leak electricity and hurt sb.'s feelings, because its weight is big, is therefore preventing the spark blast, prohibiting in the high-risk district scope of fire and can not use that the present invention has then increased the Security of running environment.
7. maintenance is checked conveniently.
Description of drawings
Fig. 1 is the structural representation of a kind of general hydraulic turbine for cooling tower of the present invention.
Fig. 2 is the plan view of Fig. 1 water turbine.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of general hydraulic turbine for cooling tower of the present invention is equipped with casing 1, main shaft 2, bearing 3 and impeller 4, and impeller 4 is placed on the main shaft 2.Casing 1 is provided with water intake 11 and water outlet 12.Be provided with outlet area 13 in the casing 1, the slowly-releasing space must be satisfied in outlet area 13.Complete machine has been cancelled motor and retarder.
Water intake 11 is provided with into water guide plate 14.Water intake 11 can also be provided with branching block 15.Outlet area 13 is enclosed to put by coaming plate 16 and is formed, and its space should be enough big.Water intake 11 oblique settings, the blade of impeller 4 are vertical the setting.Also water intake 11 vertically can be provided with, the blade of impeller 4 is oblique setting.
Hot water is entered by water intake 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.Water inlet through-flow impeller 4 backs are 13 slowly-releasings in the outlet area, make impeller 4 drive the blade rotation, after water outlet 12 outflows.Whole flow process is happy.
The primary condition of work of the present invention is flow and lift, and lift was exactly the energy of water turbine when flow was determined, cooling tower necessarily possesses into tower hydraulic pressure in actual applications, advances tower hydraulic pressure and is the energy that can change, satisfies the actual axle power of impeller blade.
The tubular turbine impeller is subjected to twice impact, and current reduce at the moment of momentum of the initial blade inlet moment of momentum to initial blade outlet port, this part momentum of minimizing be exactly for the first time the water impact impeller convert the momentum of kinetic energy to.Then entered the next blade of the runner on diameter opposite by flowing water flow, current also reduce at the moment of momentum of the ingress of the next blade moment of momentum to the outlet port, make impeller accept water impact for the second time and convert kinetic energy to.
Tubular impeller has the advantages that to be hit for twice.Because of current continuous, the outlet velocity of initial blade equals the entrance velocity of next blade, the exit momentum later by initial blade reduces, this part momentum that reduces is the energy that promotes the impeller rotation, water flow behind the minimizing momentum has become the momentum of Driving force to the ingress of next blade, thereby has obtained the energy that impacts once more.In order to obtain impeller adiabatic efficiency preferably, require as far as possible little at the unemployed energy in the outlet port of impeller, promptly the absolute velocity in the outlet port of next blade trend zero as far as possible.The lift of current is exactly the energy of water turbine, and lift is high more, and the merit that momentum is done is just big more.Cooling tower necessarily possesses into tower hydraulic pressure in actual applications, advances tower hydraulic pressure and is convertible energy, can satisfy the actual axle power of blade.
