Abstract

The utility model discloses a mixed-flow type adjustable-speed hydraulic turbine used for an industrial cooling tower, which comprises two lobster-tail water inlet pipes; the water inlet pipes are connected with a fixed seating ring; a device capable of adjusting the rotational speed is arranged in the center of the fixed seating ring; the center of the fixed seating ring is connected with a mixed-flow type turning wheel through the input shaft (the lower shaft) of a reducer; and a blower blade is connected to the output shaft (the upper shaft) of the reducer. The hydraulic turbine adopts the novel mixed-flow type turning wheel and the speed adjusting device, so that the utilization ratio of the return water static energy of the industrial circulating water thereof is higher than that of an impulse-reaction hydraulic turbine, and the efficiency can be higher than 95 percent.

Description

Industrial cooling tower mixed-flow variable-speed water turbine
Technical field
The utility model relates to a kind of industrial cooling tower that is used for.Especially a kind of mixed-flow variable-speed water turbine that relates to 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 lose water flow.
The model utility content
Task of the present utility model provides the industrial cooling tower mixed-flow variable-speed water turbine 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 variable-speed water turbine.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.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 variable-speed water turbine.It comprises the water intake of two different-diameters and the housing of lower outlet, circular seat ring, and the variable-speed valve block, francis turbine runner, planetary reducer, the retarder lower shaft connects runner, and last axle connects fan blade, brake disc and braking force control system.
The model utility water turbine is on the basis of traditional water turbine, and intake pipe is transformed, and adopts two spiral cases of the outer connection of seat ring, spiral case is symmetrically distributed around the axis of seat ring, with the intake pipe of different-diameter, symmetric inlet, the intake pipe of two different-diameters, the runner of driving water turbine.The flow of major diameter intake pipe is big, therefore can dependable flow.The minor diameter intake pipe increases flow velocity, can add the speed of great wheel, solves the problem of rotational speed of water turbine deficiency in the past, and this is that other water turbine are not available.
Described variable-speed valve block is made up of the dash blade.At current is during by the dash blade, enters water pipe and distributes waterpower, promotes the runner rotation.Consistent in order to guarantee to transform the back and to transform preceding parameter matching, can finish adjusting work by the modulating valve of hydraulic pressure.
Described runner by blade and up and down ring connect and to form, current are besiegeed blade.Blade drives the runner rotation, the runner drive main spindle, and main shaft drives speed reducer, and the output shaft of speed reducer drives the fan blade rotation.
Described brake disc and braking force control system are to guarantee blower fan when safeguarding, blade remains static, and avoid safeguarding or service work injury to personnel evil.This also is that other water turbine are not available.
The utility model industrial cooling tower can draw from technique scheme with mixed-flow variable-speed water turbine: this water turbine is mixed-flow, blade profile advanced person, and water inlet distributes rationally, has improved the rotating speed of water turbine, and braking device is safe and reliable.This is that other water turbine are unexistent.Use it to replace the motor of blower fan, can make 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 runner.The variable-speed operation reduces drift ice.
3, operate steadily, noise is low, and the life-span is long, and Security is good.
The problem of blade rotation when 4, braking device solves maintenance.
Description of drawings
Fig. 1 is an industrial cooling tower of the present utility model mixed-flow variable-speed water turbine cross-sectional view.
The intake plan view of housing of Fig. 2.
Embodiment
Embodiment 1
The utility model is to be connected to form with bolt by following components.Referring to Fig. 1 and Fig. 2, this water turbine forms housing by the intake pipe (1) of two different-diameters.The inline set ring stand of housing (2).Be provided with adjusting valve block (3) at ring stand (2).Planetary reducer (4) is arranged on ring stand.Reducer input shaft (5).Under input shaft (5), connecting runner (6).On retarder, there is output shaft (7) to connect blade, brake disc and braking force control system (9).
Embodiment 2
Referring to Fig. 1 and Fig. 2, this machine uses novel mixed-flow variable-speed water turbine, and working procedure is; Backwater is to enter housing ringwise from (1), by (3) control inflow and flow velocity.The annular water flow ecto-entad is besiegeed runner (6) and is rotated.Passing water behind the runner enters draft tube (8) and enters the cloth supply mains downwards.Runner (6) drives reducer input shaft (5) and rotates to clockwise direction, and reducer output shaft (7) drives blade rotation.
