Description
Technical field
What the present invention relates to is the centrifugal pump parts, and concrete is the no impeller taper hollow screw axis that a kind of centrifugal pump is used.
Background technique
Along with the continuous development of science and technology, the application of liquid drive technology is also more and more wider, and just seems very important as the core liquid pump of liquid driving mechanism, has reached the stage that can't abandon at present.Liquid pump is various in style, various informative at present, can under the different environment occasion, use, and shows its different advantages and performance fully, following common problem yet sum up the pump shaft ubiquity of concluding liquid pump commonly used at present:
1, power consumption is bigger: liquid pump commonly used drives pump shaft and wheel rotation by motor, and the moment of rotating undoubtedly is just big, and especially the big negative angle component of impeller rotational resistance in water is many, many actings, and energy consumption is just big naturally.
2, the complex structure consumptive material is more, and the pump shaft of the liquid pump of all size model of using at present mostly has impeller, more complicated all comparatively speaking structurally, and the corresponding raw material that consume are just more, and this also means the increase of cost.Dismounting brings certain degree of difficulty when also giving maintenance.
3, efficient is not high, and the life-span is not long: pump shaft commonly used is now compared with the power of pump housing output from the energy consumption of input, and efficient does not all include too high, and damaged situation will occur behind the operation certain hour, and working life is generally not long.
4, unit list usefulness, non-interchangeability; The pump shaft of the various liquid pump that uses now, the many places sealing seals bad bearing and is easy to damage, and reduces working life greatly.
Do not have as yet at present simple in structure, do not have that impeller, consumptive material are few, power consumption less, pump shaft that efficient is high.
Summary of the invention
The objective of the invention is to the liquid pump pump shaft that uses at present exist that the complex structure consumptive material is many, power consumption greatly, problem such as efficient is not high, and provide simple in structure, consumptive material is few, less energy consumption, leak free a kind of centrifugal pump are used blade wheel-free hollow screw axis.
The technological scheme that adopts is:
The blade wheel-free hollow screw axis that a kind of centrifugal pump is used comprises taper hollow shaft, preceding spiral stream guidance body, rear screw deflector, cavity cone, rotor, lock nut;
The two ends of said taper hollow shaft are respectively arranged with water intake, water outlet, spiral stream guidance body and rear screw deflector before being equiped with in the taper hollow shaft, and forward and backward spiral stream guidance body is fixedly connected with taper hollow shaft inwall respectively; The front end of rear screw deflector is provided with a cavity cone, and the rear end of cavity cone is fixedly connected with the rear screw deflector, and the front end of cavity cone is fixedly connected with taper hollow shaft inwall; The wall of cavity cone is provided with a plurality of osculums.
Above-mentioned rotor is set in the outside of taper hollow shaft, and the end top of rotor is stuck on the taper hollow shaft, and the other end of rotor is fixed through lock nut, and lock nut is connected through screw threads for fastening with the taper hollow shaft.
The front end of above-mentioned cavity cone is provided with import.
Working principle
Water flows to from the water intake of blade wheel-free hollow screw axis; Enter into the import of cavity cone front end along preceding spiral stream guidance body; Rotor rotate in the magnetic field of stator and drives the taper hollow shaft and rapidly rotate after the energising, because of the centrifugal force of rotation generation makes water rapidly rotation in the cavity of cavity cone, " throws away " from a plurality of osculums hastily; The glassware for drinking water that " throws away " has very high speed; Very big kinetic energy, the cavity between cavity cone and taper hollow shaft inwall are done swirling motion and " are flushed to " the rear screw deflector apace, and water just sprays from water outlet with great kinetic energy along the rear screw deflector continuously.
The present invention has adopted new technology, new method, thereby have tangible advantage:
1, the present invention is an internal spiral tube chamber exocentric structure, greatly reduces the resistance of fluid, does not produce component because of the spiral stream guidance body flows fluid; Fluid all moves in the chamber, reduces fluid resistance, the eddy current negative angle; So unpowered loss, liquid speed is big, and discharge capacity is big; The efficient of comparing with present general liquid pump has improved 30%, and fluid flows in the hollow axocoel of taper, plays the effect of cooled rotor simultaneously; The motor that complete machine need not look like common water pump specially installs fan cooled additional, and energy consumption has reduced by 24% on year-on-year basis.
2, liquids in general has floating wall phenomenon in running shaft; And be converted into hydraulic power to floating wall phenomenon through spiral motion, and making no impeller taper hollow shaft obtain the secondary pressurization and quicken, pump shaft is to integrate spiral, eddy current, centrifugal; Give full play to advantage separately, cut down the consumption of energy.
3, owing to be no blade wheel structure, so reduced the cycle of raw material and processing, cost reduces greatly, and pump shaft is small and exquisite, and is very unique.
4, because simple in structure, rate of fault is just few, and the maintenance nature is just low, adds and makes the meticulous of processing and adopt the quality material machine life to increase greatly, and long-time use is not leaked, and does not stop up cooling certainly, selflubricating.Life-span is higher more than 20 times than common Pump Axle.
Global design science of the present invention, reasonable, simple in structure, easy to make, materials used is few, and quality of materials is good, and is with low cost.Dismounting is simple and direct, and the regular maintenance amount is few, and is stable and reliable for performance; Energy saving, efficient is high, and is practical; The present invention is key, a core component of manufacturing centrifugal pump, also can be used as the spare part of the centrifugal pump of corresponding work unit use such as family, factories and miness, enterprises and institutions, agricultural irrigation, tap water.
Need to prove: under the prerequisite that does not change the principle of the invention and design, change of having done or distortion all belong to protection scope of the present invention.
