Abstract
The utility model provides a mixed-flow type efficient double volute hydraulic turbine for an industrial cooling tower, which comprises two water inlet pipes (1) on the same side, and water inlet pipes (10) symmetrically distributed in a lobster-tail manner; the water inlet pipes are fixedly connected with a seating ring (2); a water guide blade (3) is arranged in the seating ring; a cover plate is arranged on the upper end surface of the seating ring; a hub connection component (4) is mounted at the upper end of the cover plate; and the center of the cover plate is connected with a mixed-flow type turning wheel (5) through a shaft (a lower shaft) and connected with a blower blade through another shaft (an upper shaft (9)). The hydraulic turbine adopts a novel mixed-flow type turning wheel structure and a braking device, so that the utilization ratio of hydraulic energy of industrial circulating water thereof is higher than that of an impulse-reaction hydraulic turbine, and the efficiency can be higher than 95 percent.
Description
Technical field
The utility model relates to a kind of industrial cooling tower that is used for.A kind of mixed-flow double volute highly effective water wheel machine of especially alternative motor.
Background technique
Industrial cooling tower is all wanted forced ventilation generally speaking.Drive fan blade by the motor driving retarder and rotate the suction air quantity.Make the hot water of the need cooling that produces in process of production take away heat through air exchange.Used motor of industrial cooling tower and retarder are abominable because of environment, and working life is short, noise of motor is big, consumed power is big, and motor-driven fan blade rotating speed is unadjustable, easily produce the water that wafts, and cause waste.Existing water turbine is to the circulating water working condition requirement height of cooling tower.Add that form turbine efficiencies such as impact type, impact are lower, do not reach specified standards so produce the fan blade rotating speed, or loss water flow.
The model utility content
Task of the present utility model provides the industrial cooling tower mixed-flow double volute highly effective water wheel machine after a kind of the improvement.This water turbine head is low, and flow loss is few.Make full use of the transformation of energy of industrial cooling tower backwater.Water can be become mechanical energy to rotate.Substitute motor and energy-conservation.Because the efficient height of novel mixed-flow double volute highly effective water wheel machine.Rotating speed is far above the specified standards of blower fan.So this water turbine needs retarder just to can be used for blower fan of cooling tower.Fundamentally solved the problem of former rotational speed of water turbine deficiency.For the safety of safeguarding and overhauling, design and installed additional braking device.Its Mi has mended deficiency and the defective that does not have braking device in all blower fan of cooling tower that national patent is announced.
It is as follows that the utility model solves its technological scheme:
A kind of mixed-flow double volute highly effective water wheel machine.It forms housing by two intake pipes (10) with diameter homonymy intake pipe (1) shrimp shape of tail.By circular seat ring (2) coupling housing.The modulating valve (3) of 6 to 8 adjustable flows and hydraulic pressure is set in circular seat ring (2).Connect francis turbine runner (5) at circular seat ring center by coupling shaft assembly (4) main shaft lower end.Coupling shaft assembly (4) main shaft upper end (9) connects fan blade.Brake disc (7) is connected with main shaft (9).Braking force control system (6) is fixed on the coupling shaft assembly (4).Connect firmly seat ring (2) in tail water (8) pipe upper end.The water intake of two same diameter and be the housing of the shrimp tail pipe water outlet that distributes of symmetry axis with the seat ring axis, circular seat ring, francis turbine runner, coupling shaft assembly lower shaft connects runner, last axle connection fan blade.
The intake pipe of described two same diameter, dependable flow, smooth running.
Described runner by 14-17 piece blade and up and down ring connect and to form, current are besiegeed blade.Blade drives the runner rotation.
Current enter water pipe and distribute waterpower by 6-8 dash blade.
The utility model industrial cooling tower can draw from technique scheme with mixed-flow double volute highly effective water wheel machine: this water turbine is mixed-flow, blade profile advanced person, makes full use of potential energy, flow, the lift acting of industrial cooling tower backwater.Efficient can be brought up to more than 95%.Variable-speed, anti-drift ice.The alternative motor power of this water turbine makes industrial cooling tower economize on electricity 100%.
The utility model technical characterstic and effect are as follows:
1, substitute machine operation, economize on electricity significantly.
2, novel mixed-flow water turbine reduces drift ice, falls low pipe resistance.
3, reduce windage.
4, operate steadily, noise is low, and the life-span is long, and Security is good.
Safety problem such as blade rotation when 5, braking device solves maintenance.
6, easy construction, economical with materials.
Description of drawings
Fig. 1 is an industrial cooling tower of the present utility model mixed-flow double volute highly effective water wheel machine cross-sectional view.
The intake plan view of housing of Fig. 2.
Embodiment
The utility model is to be connected to form with bolt by following components.Referring to Fig. 1 and Fig. 2, this water turbine is formed housing by two intake pipes (10) with diameter homonymy intake pipe (1) shrimp shape of tail.The inline set ring stand of housing (2).Be provided with adjusting valve block (3) at ring stand (2).A connection part (4) is arranged on ring stand.Axle connection part (4) lower end is connecting runner (5).Connect blade in axle connection part (4) upper end.Brake disc (7) connects main shaft (9), and braking force control system (6) is fixed on a connection part (4) and goes up control brake dish (7).
Working procedure of the present invention is: when current from spiral case (10) when entering water turbine, current are along with the guiding of spiral case arrives seat ring (2), the pilot flow of water guide blade (3) is to runner (5) in passing through seat ring, promoting runner (5) rotates, discharge from draft tube (8) from the water that runner (5) comes out, main shaft rotates with runner (5), rotates thereby drive fan blade.
Referring to Fig. 1 and Fig. 2, this machine uses novel mixed-flow double volute highly effective water wheel machine, and working procedure is; Water is to enter housing ringwise from (1), along with the guiding arrival seat ring (2) of spiral case, by (3) control inflow and flow velocity.The annular water flow ecto-entad is besiegeed runner (5) and is rotated.Enter draft tube (8) by the water behind the runner (5) and enter the cloth supply mains downwards.Runner (5) drives main shaft (9) and rotates to clockwise direction, thereby drives blade rotation.When not working, brake disc (7) and braking force control system (6) work stop operating blade, guarantee maintainer's safety.
