Beneficial effect：
Main innovation point of the present invention is as follows：
1. one of present invention innovation：Rotor simplifies when transmission flywheel, system.
The transmission shaft of heat power machine, generator, motor and water pump is directly connected in the present invention, when individually using fuel
Drive water pump when, heat power machine must first drive generator and motor, then drive water pump, though at this time motor do not produce it is dynamic
Power, generator also do not generate electricity, and rotor passively dallies, but serve as between heat power machine and water pump with buffering, stablize it is used
Property flywheel.
System relative to other using engine and motor parallel, separates motor when by engine driving water pump,
Although the friction of motor idle running, complicated, poor practicability can be reduced.And the layout structure of mechanical series is used to realize heat
The straight expelling water pump of engine, transmission efficiency, is not only convenient for motor and water pump is operated alone, and also allows for heat power machine Independent Power Generation, makes
Whole device is simple and reliable for structure, while grafting can be facilitated existing and very ripe fuel generator and pump technology, makes this
Invention has good practicality.
The two of innovation of the invention：Generator, motor are transformed into antigravity bearing, system high efficiency.
When motor only makees transmission shaft and inertial flywheel, since rotor weight is heavier, certain friction energy loss can be produced, and
Due to using the structure of antigravity Exciting Windings for Transverse Differential Protection in motor, it will not only increase frictional force, can also reduce whole system on the contrary
Frictional resistance.By increasing extraction wire in generator or motor stator, one group is isolated in stator winding top
Or multigroup winding, individually it is powered as antigravity Exciting Windings for Transverse Differential Protection, and to it, using stator core and rotor core, forms one
The electromagnet structure that can up attract rotor, by controlling electric current, enables electromagnetic attraction size to allow generator or motor
The horizontal support bearing of transmission shaft or together with the pressure straight down suffered by the horizontal support bearing of engine and water pump drive spindle
Reduce or be zero.Since engine, generator, motor and water pump are horizontal installation, and the moving component in four,

It is only related with the radial pressure straight down that bearing is born to wipe power, and it is unrelated with the level of torque of pump load and transmission shaft, one
The denier pressure reduces even zero, will substantially reduce frictional resistance when bearing rotates, while can reduce vibrations and noise.
This plain bearing adds rotor and the frame mode of antigravity Exciting Windings for Transverse Differential Protection, energy similar with magnetic bearing structure
The gravity that bearing radial direction is born is set to reduce even to zero, equivalent under weightlessness, acquisition is similar to magnetic suspension shaft
The effect held.Due to using engine, generator, motor and the direct cascaded structure of water pump, whole generator and electronic at this time
Machine is not only into connection engine and the transmission shaft and flywheel of water pump, and when coupling device is using being rigidly connected, also becoming to prop up
The antigravity bearing of engine and water pump itself transmission shaft is supportted, thus the entirety of this generation antigravity effect is named as bob-weight
Power bearing.
Generator or motor become bearing, and antigravity Exciting Windings for Transverse Differential Protection structure seems very complicated, but in fact and need not send out
Additionally increasing component on motor and motor body again, bearing, rotor and stator are all that generator and motor itself are existing,
Simply by optimization stator winding, increase extraction wire, produce unique antigravity Exciting Windings for Transverse Differential Protection structure, make existing generator and
Motor becomes a huge antigravity bearing, and a more good zero-g inertial flywheel, and cost only has magnetcisuspension
The some thousandths of that floating axle is held, this is exactly the ingenious part of the present invention.
When generator or motor need to recover power generation and driving function, pass through the switching list in antigravity control module
Member, switches over the lead of antigravity Exciting Windings for Transverse Differential Protection, and antigravity Exciting Windings for Transverse Differential Protection is returned to generator or motor immediately
In stator winding.
Further, the present invention also has a variety of operating conditions, and therefore, flexibility is extremely strong.
In conclusion the double dynamical water pump and double dynamical water pump control method of the present invention are easy to implement, it is simple in structure.Operation
Flexibly, energy utilization rate is high, is adapted to promote and apply.
