Description

Used for cooling tower high pulling torque reaction turbine
Technical field
The utility model relates to a kind of water turbine for cooling tower, particularly relates to a kind of used for cooling tower high pulling torque reaction turbine.
Background technique
Water turbine is to be the transformation of energy of current the dynamic power machine of rotating mechanical energy, and it belongs to the turbomachinery in the fluid machinery.Water turbine can be divided into impulse turbine and reaction turbine two big classes by working principle.The runner of impulse turbine is subjected to the impact of current and rotates, and the pressure of current is constant in the working procedure, mainly is the conversion of kinetic energy; The runner of reaction turbine is subjected to the reaction force of current and rotates in water, the pressure of current energy and kinetic energy all change in the working procedure, but mainly is the conversion of pressure energy.At present, the various water turbine of employed aborning counterattack type not only can only use in its specific head and range of flow, and can only just can reach higher efficient under optimum operating condition.And its complex structure and huge, the manufacturing of equipment, transportation etc. have very big difficulty, thereby have seriously restricted the development and use process of hydraulic power potentials, even can't develop some hydraulic power potentials at all.
Simultaneously hydrodynamic(al) can cooling tower all be that water turbine is the high rotating speed operation of low moment of torsion all the time, adopts deceleration system to carry out the conversion of rotating speed, complex structure, and runner move damage easily under high-speed state, and it is very inconvenient to keep in repair.Adopt deceleration system to carry out the conversion of rotating speed simultaneously, cause whole water turbine vibrations big, the noise height.Moreover rotary speed system needs to add lubricant oil before work, very easily occurs leakage of oil when high speed operation, causes the pollution of circulating water, thereby influences the normal operation of main process equipment, conversion efficiency is low can not realize truly 100% energy-conservation.
The model utility content
In order to solve the problems of the prior art, the utility model discloses low, the no deceleration system of a kind of rate of fault simple in structure, noise is low, vibrations are little, long service life, used for cooling tower high pulling torque reaction turbine that energy conversion efficiency is high.
Technical solution adopted in the utility model is:
A kind of used for cooling tower high pulling torque reaction turbine, comprise spiral case, runner, waste pipe, it is characterized in that: also comprise gland seal device, bearing housing and running shaft, be provided with pumping chamber in the described spiral case, in pumping chamber, be provided with runner, be connected with waste pipe in the pumping chamber bottom, center, upper-end surface at pumping chamber is fixed with gland seal device, the gland seal device upper end is provided with bearing housing and both are separated from each other, described running shaft is installed by bearing housing and gland seal device, and the lower end of running shaft is inserted pumping chamber inside and is connected with runner, and the upper end of running shaft is equipped with blower fan.
Preferably, described runner is a kind of in francis turbine runner, kaplan turbine runner, inclined flow turbine runner and the tubular turbine runner.
Preferably, described spiral case offers one or two water intake, and when water intake was two, these two water intakes were center symmetrical reverse setting with the runner.
Preferably, described gland seal device is stuffing seal, mechanical seal device, magnetic liquid sealing device.
The beneficial effects of the utility model are: the utility model reaction turbine utilize current pressure can and kinetic energy as the power source of blower fan, be suitable for the low situation of cooling tower head.Adopt the slow-revving mode of operation of high pulling torque during the utility model work, saved deceleration system, optimized structural design, noise is low, vibrations are little, use maintenance convenient, has also reduced the cost of production of enterprise.Simultaneously the leakage of oil situation can not occur, make the main process equipment operation normal, improve the utilization ratio of water energy greatly.Moreover the utility model has adopted the symmetric inlet structure, and the current formation that makes water turbine is that the symmetrical reverse at center distributes with the runner, and water impact and pressure that runner is subjected to are more even.

Fig. 1 is the two water intake cross-sectional view of the utility model;
Fig. 2 is the plan view of the two water intakes of the utility model;
Fig. 3 is the utility model list water intake cross-sectional view;
Fig. 4 is the plan view of the utility model list water intake.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Spiral case water intake of the present utility model can be set to 1-2, is single water intake mode or two water intake mode.When water intake is set to two, these two water intakes are center symmetrical reverse setting with the runner, setting water impact and pressure that runner is subjected to is more even like this, can reduce the vibration of water turbine greatly, and vibration of cooling tower tower body and noise when making operation are effectively reduced.
The used for cooling tower high pulling torque reaction turbine that has two water intakes under the following mask body introduction.
As illustrated in fig. 1 and 2, used for cooling tower high pulling torque reaction turbine, comprise spiral case 1, runner 4, waste pipe 3, it is characterized in that: also comprise gland seal device 8, bearing housing 5 and running shaft 6, be provided with pumping chamber 2 in the described spiral case 1, in pumping chamber 2, be provided with runner 4, be connected with waste pipe 3 in pumping chamber 2 bottoms, center, upper-end surface at pumping chamber 2 is fixed with gland seal device 8, gland seal device 8 upper ends are provided with bearing housing 5 and gland seal device 8 and bearing housing 5 and are separated from each other, such design has prevented gland seal device 8 in case damaged, thereby the water of spiral case 1 enters bearing housing 5 along running shaft 6 causes bearing to damage in early days, described running shaft 6 is installed by bearing housing 5 and gland seal device 8, and the upper end of running shaft 6 is equipped with blower fan.Runner 4 can carry out appropriate design according to the flow velocity of water, the height pressure of water and the efficient of required water turbine, can choose any one kind of them in the runner of Francis turbine, axial flow hydraulic turbine, inclined flow turbine and tubular turbine.It is the setting of center symmetrical reverse with runner 4 that spiral case 1 of the present utility model is provided with 7, two water intakes 7 of two water intakes, and runner 4 is just more steady when rotating like this.Described gland seal device is stuffing seal, mechanical seal device, magnetic liquid sealing device.
