The increase of motor load, the stress of thrust bearing shoe valve is also gradually increased and causes a watt temperature rise, finally causes tile kilning
Accident.
Utility model content
This utility model provides a kind of Double shaft-extension without thrust horizontal mixed-flow water turbine generator set, to solve water
Turbine generator group, along with the increase of generator load, makes the stress of thrust bearing shoe valve also be gradually increased and cause Wa Wen
Raise, the problem finally causing burning accident.
This utility model be employed technical scheme comprise that, a kind of Double shaft-extension is sent out without thrust horizontal mixed flow water wheels

Figure.
Wherein, 1. main shaft, 2. journal bearing, the 3. hydraulic turbine, 4. electromotor, 5. runner.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
This utility model provides a kind of Double shaft-extension without thrust horizontal mixed-flow water turbine generator set, such as Fig. 1 institute
Show,
Including electromotor 4, run through electromotor 4 and be provided with the main shaft 1 for providing power for it, main shaft 1
Two ends are respectively erected on main shaft 1 on journal bearing 2, and the two ends of main shaft 1 are connected to the hydraulic turbine
3, two journal bearings 2 are respectively used to bear the radial force that the hydraulic turbine 3 of correspondence produces, two water wheels
Machine 3 is used to drive shaft 1 and rotates.Wherein, the hydraulic turbine 3 is connected with main shaft 1 by runner 5.
This utility model one twin shaft without thrust horizontal mixed-flow water turbine electricity-generating method is, the master of electromotor 4
Axle 1 two ends are connected to the hydraulic turbine 3, rotate to drive by two hydraulic turbine 3 drive shaft 1 and send out
Motor 4 generates electricity.Wherein, two sections of stretching out of main shaft 1 are respectively erected on journal bearing 2.
Existing horizontal mixed-flow water turbine generator set is the structure that a hydraulic turbine connects an electromotor, when
When the load of the hydraulic turbine is the biggest, its axial thrust produced on main shaft is the biggest, so generally by arranging
Thrust bearing offsets the axial thrust that main shaft is produced by the hydraulic turbine.
And this utility model by being all connected with the hydraulic turbine at main shaft two ends so that two hydraulic turbines are to main shaft
Axial thrust is cancelled out each other, and eliminates the thrust bearing being arranged on main shaft, between the hydraulic turbine and electromotor
Only need to set up common journal bearing, owing to the volume of journal bearing is less than thrust bearing, such one
It is reduced by the volume of whole generating equipment.
Simultaneously as an electromotor can connect two hydraulic turbines in this utility model, so in generating
In the case of machine output is constant, the power of the single hydraulic turbine can only connect a hydraulic turbine than original
Power reduce half, i.e. runner diameter reduces, rotational speed of water turbine improve, the number of pole-pairs of electromotor
Decrease, it also reduce the volume of overall generating set, the turbine-generator units of flow big to low water head
Reduction to cost is particularly evident.
Such as: originally driven the electrical power generators of 2000KW by the hydraulic turbine of 2000KW, according to
Structure of the present utility model, by the turbine-generator units of the 2000KW hydraulic turbine of two 1000KW
Drive, on the premise of ensureing generated output, reduce the volume of overall generating set.
Otherwise, originally need the electromotor of two 1000KW to work, according to knot of the present utility model simultaneously
Structure, only need to use the hydraulic turbine of two 1000KW to drive the electromotor of a 2000KW, is protecting
On the premise of card generated output, reduce the volume of overall generating set and decrease factory building area.
The hydraulic turbine of same type, mirror image is arranged on generator shaft two ends, is just being equivalent to a hydraulic turbine
Turning, another hydraulic turbine inverts, owing to two hydraulic turbines use same speed regulator, so it is basic to exert oneself
Relative equilibrium, and each turbine efficiency is not changed in, journal bearing end face is provided with thrust surface, can prevent
The small play of axial force.
