Background
Fluid propulsion technical products are more, mainly including centrifugal pumps, reciprocating pumps, screw pumps, gear pumps, axial-flow pumps, propellers and the like, the existing underwater propulsion system mainly comprises the axial-flow pumps and the propellers, but the underwater propulsion system is complex in structure and obviously low in efficiency, and the fundamental reason of the system is negative influence caused by shafting.
Therefore, a technical route of magnetic suspension and spiral ring fluid structures is disclosed in the prior patent CN201210436592.2, and the technical product is approved by the industry through actual test and scene experience, namely the industry is called a linear fluid technology and is commonly called a shaftless pump jet propeller technology, and in the hydrodynamic environments of navigation, spaceflight, industry and agriculture, buildings and civil consumer products, users apply the technology as a key product of future hydrodynamic energy conservation and emission reduction, and the technology is derived from the fact that the fluid propulsion efficiency can be greatly improved, and social resources can be saved by simply realizing the body structure. The realization of the technical function necessarily introduces a plurality of new key technologies.
The comprehensive efficiency of the propeller and the motor of the conventional underwater propeller is about 15-25%, the most important point is that the rotating speed is increased, and the efficiency is reduced more quickly although the navigational speed is also increased. The invention relates to a straight line fluid technology underwater application technology, which is characterized in that the efficiency of a shaftless pump jet propeller product is over 50 percent, the efficiency is not reduced mainly due to the fact that the rotating speed is increased, the navigational speed is increased, and the shaftless pump jet propeller product is simple in process and high in manufacturability.
The shaftless pump-jet propeller is generally divided into three types of ordinary type, rapid type and high-speed propulsion according to the navigational speed capability of underwater propulsion, generally bears lives, comprises that passenger ship propulsion belongs to the ordinary type, the navigational speed is 1-15 knots, the acceleration of the over-rapid navigational speed is not suitable for life bodies, an underwater robot with special purposes needs to quickly react, actively avoid risks and track preys, the navigational speed is 25-35 knots, the faster requirement exceeds 50 knots, and even 150-knot navigational speed propellers in some countries are reported according to information. The requirement of the flow speed of the discharged water of the high-speed shaftless pump jet propeller is very fast, the design of a fluid module of the propeller is obviously different from that of a common propeller, so that the algorithms of the propelled fluid are different, the corresponding structures of the algorithms are also different, and particularly, the bypass structure of the fluid module belongs to a specific technology. Therefore, the inventor group of the patent applicant carries out intensive research on the characteristics to obtain the ducted structure characteristics of the fluid module of the A2B2C type shaftless pump jet propeller, and the results are disclosed and claimed.
The technology of the invention is a key technology introduced by a linear fluid technology in a deep water environment, namely an A2B2C type shaftless pump jet propeller fluid module ducted structure technology, and the traditional underwater propulsion technology does not relate to the technology and has no direct comparison. However, in practice, without this technique, the high-pressure and high-speed propelling function of the shaftless pump jet propeller will be lost.

Detailed Description
According to the technical characteristics of the invention, the axial three-dimensional schematic diagram of the A2B2C type shaftless pump jet propeller fluid module duct structure in the attached figure 1 shows that the inner wall of the rotor duct drives all stages of spiral rings to rotate, when fluid medium is pressurized from a first-stage spiral ring (1) entering the duct, the fluid medium enters a first-stage guide ring (13) for pressurization, then is pressurized by a second-stage spiral ring (2), then enters a second-stage guide ring (12) for pressurization, and so on, the fluid medium is pressurized by n stages of guide rings, and is jetted out of the duct after the kinetic energy is pressurized step by step, so that the kinetic energy increasing process of the fluid medium is completed.
According to the technical characteristics of the invention, the axial three-dimensional schematic diagram of the A2B2C type shaftless pump jet propeller fluid module culvert structure in the attached figure 1 shows that when fluid enters the culvert, the core rod is static and motionless relative to the inner wall of the rotor culvert, and the guide ring is static and motionless relative to the inner wall of the rotor culvert due to the synchronous fixing function of the core rod and the guide ring, so that the fluid medium is restrained from rotating radially in the culvert, and the radial energy is converted into axial energy, thereby achieving the effect of forward pressurization of the fluid culvert.
