Description
Technical field
The present invention relates to propeller, and in particular to a kind of combined type pump-jet propulsor.
Background technology
At present, waterborne vessel and submarine mainly use propeller to be rotated as mechanical equivalent of light feeding device, propeller by blade
Engine rotation power is converted into the device of propulsive force, shortcoming is that propulsive efficiency is low, and noise is big, as propeller of new generation
Although pump-jet propulsor and water jet propulsion pump performance are better than propeller, the rotor of pump-jet propulsor after current acceleration to that can transmit
Stator rectification is given, behind the end of transmission mechanism, high speed side fluid layer on the outside of flow field can be driven current to drawing close at center
Mechanism end forms one section of low regime（Low-pressure area）.No matter the speed of fluid has much, this section of low-pressure area can all exist, then pass through
After a distance, the high speed side fluid layer in outside can be drawn close to this region, and after drawing close, friction will be produced between fluid（Trailing vortex）Make
Into energy loss, the propulsive efficiency of pump-jet propulsor is reduced；Water jet propulsion pump requirement has enough and relatively stable influent streams.And
And water jet propulsion pump is in the low speed of a ship or plane（Less than 20 sections）Under it is less efficient.
The content of the invention
High it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of propulsive efficiency, radiated noise is low, faces
The high combined type pump-jet propulsor of boundary's speed of a ship or plane.
The technical scheme is that：
Combined type pump-jet propulsor, including outer conduit, outer conduit are in collapsed shape, and outer conduit both ends are respectively water inlet
And water outlet, propeller inside set pump-jet propulsor and water jet propulsion pump, pump-jet propulsor includes pump spray rotor, pumps spray stator
Motor is sprayed with pump, pump spray motor is fixed in outer conduit by four fixed-wings, pump spray motor rear portion connection pump spray rotor, pump
Spray rotor rear and pump spray stator rectification is set, pump spray stator is connected with outer conduit, and spray pump impeller is set at pump spray stator center
Motor, spray pump impeller motor connection water jet propulsion pump.
The beneficial effects of the invention are as follows：Pump-jet propulsor and water jet propulsion pump on the premise of respective advantage is retained, the two
Shortcoming mutually makes up, and the propeller radiated noise after combination is low, and thrust loss can be less, and propulsive efficiency higher, the critical speed of a ship or plane is high,
Suitable for submarine and waterborne vessel.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
The 1 outer conduit 2 pump spray motor 3 fixed-wing 4 pump spray pump spray 6 spray pump impeller motor of stator of rotor 5
7 water jet propulsion pumps.
Embodiment
Combined type pump-jet propulsor, including outer conduit 1, outer conduit 1 are in collapsed shape, and 1 both ends of outer conduit are distinguished
For water inlet and water outlet, propeller inside sets pump-jet propulsor and water jet propulsion pump 7, and pump-jet propulsor includes pump and sprays rotor
4, pump spray stator 5 and pump spray motor 2, pump spray motor 2 are fixed in outer conduit 1 by four fixed-wings 3, after pump spray motor 2
Portion's connection pump spray rotor 4,4 rear of pump spray rotor set pump spray 5 rectification of stator, and pump spray stator 5 is connected with outer conduit 1, pump spray
Spray pump impeller motor 6 is set at 5 center of stator, and spray pump impeller motor 6 connects water jet propulsion pump 7.
The present invention promotes the propeller mode combined with hydraulic jet propulsion using pump spray, avoids conventional propeller and promotes anti-sky
The shortcomings of property changed is poor, and radiated noise is big.During work, pump spray rotor 4 can pass to pump spray 5 rectification of stator, make after accelerating to water
The fluid stable outflow that must be accelerated.According to the velocity profile of pump spray, since the gravity by water and outer conduit 1 shrink shape
The influence of shape, fluid, in the end of motor unit, can form a bit of low speed after the acceleration rectification of rotor and stator
Area's (low-pressure area）.No matter the speed of fluid has much, this section of low-pressure area can all exist, then after a distance, the height in outside
Fast side fluid layer can be drawn close to this region, and will produce friction after drawing close, between fluid causes energy loss, this is pump spray efficiency
Major influence factors, and water jet propulsion pump 7 is installed on this area of low pressure, it will improve this problem, because low regime is phase
To low speed, fluid still has higher kinetic energy, and this satisfies the influent stream requirement of water jet propulsion pump 7, water jet propulsion pump 7 can be with
Its performance is given play to.During optimal collocation, whole low-pressure section can just be filled up by the fluid that spray pump accelerated.This has just reached
On the premise of performance pump is sprayed with spray pump each advantage, make the purpose of the two shortcoming complementation, make propeller radiated noise of the present invention low,
Thrust loss can be less, propulsive efficiency higher,.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
It can modify to the embodiment of the present invention or equivalent substitution is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical solution, it should all cover among the claimed technical solution scope of the present invention.
