Beneficial effect:
Needle rotor fluid delivery system of the present invention can produce following beneficial effect as the blower fan of conveying or Compressed Gas:
(1) pinwheel energy transfer mode is superior and transmission efficiency is high
The function of blower fan passes to air-flow to mechanical energy exactly, and target is kinetic energy and the static energy that is converted into air-flow.Blade mainly is by compress mode mechanical energy to be converted into static energy, kinetic energy, because the compressibility of gas, generates heat energy easily in the compression process and loses.Pinwheel pin seedling is than surplus the impeller blade as many as ten times, and specific area is much bigger, mainly is by cut mode mechanical energy to be converted into kinetic energy, and the energy transfer mode is superior.Pin seedling spacing is very little, and pin seedling diameter is also little than blade, and the air-flow between the pin seedling more approaches small a fluid stream, more can satisfy the ideal flow of Euler's moment of momentum energy equation of transfer requirement, and eddy current is little more than blade wedge gap eddy current in the flow field.Eddy current is little, and it is little to generate heat, and in-fighting is just few.So pin seedling energy transfer efficiency is than blade height.
(2) pinwheel startup load is little
The pin seedling can be swung, and is flexible superior.The pinwheel the moment of inertia is littler than impeller, so pinwheel startup load is little.Under with the fan performance parameter, the configuration load of needle rotor fluid delivery system can reduce more than 1/5th than fan impeller.
(3) the pinwheel dynamic balancing realizes and the grade height easily naturally
The pin seedling of hinged constraint axially also is being easy to set, evenly is being connected in series in the evenly distributed layout of hoop energy, and after rotation was got up, the pin seedling leaned on the centrifugal force oneself to seek the equilbrium position, so the natural satisfaction degree of the dynamic balancing of pinwheel integral body is than higher.The simplified processing technology of pinwheel only needs assembling to get final product, and has cancelled the dynamic balance running link, simultaneously, keeps in repair also judicial convenience.
(4) noise is significantly little
The noise of fan impeller is very high.Its noise source has two, aerodynamic noise and mechanical noise.
The fan impeller aerodynamic noise mainly is that the impact and the eddy current of air-flow causes.Impact noise is because impeller rotates at a high speed, and blade is done cycle movement, and the gas particle is subjected to the effect of periodic compression power and produces.Impact noise has fundamental frequency, and its size is the long-pending of the wheel speed and the number of blade.Eddy current crack is that impeller produces because of gas boundary layer separates when rotating at a high speed.Wedge shape space between the blade is big, and there is significant pressure reduction blade lee face and adjacent windward side, produces the wedge shape eddy current that circles round naturally, and this is the main source of eddy current crack.
The fan impeller mechanical noise is to produce mechanical oscillation owing to the impeller revolution is uneven to form.
Compare fan impeller, the noise genesis mechanism of needle rotor fluid delivery system is greatly improved in following several respects.
(a) the pin seedling to the impulse form of gas particle no longer as blade with the boil down to master but to be cut into the master, vibration force has reduced, so the power sound level reduces.
(b) can to reach at least be more than ten times of blade quantity to the number of the arrangement of pin seedling, vibration displacement reduces more than 1/10th, the displacement sound level can reduce more than the 10dB, and pin seedling impact noise frequency increases more than ten times, interferes with other vibration may not had of resonance taken place.
(c) wedge gap of rotation pin seedling is littler more than 1/10th than blade wedge gap maximum ga(u)ge, the lee face that adds the pin seedling is near streamlined, the chance that can form eddy current is much smaller, even it also is small forming its size of eddy current, this just makes gas more smooth with separating of boundary layer, so eddy current crack is much smaller.
(d) startup of pinwheel and rotatable dynamic balance performance increase significantly than impeller.So the mechanical noise that the pinwheel revolution causes also significantly reduces.
Comprehensively estimate, the needle rotor fluid delivery system can be cut down conventional fan aerodynamic noise level, the mechanical noise level can reach 10～40dB (A), concrete apparent wind machine size and deciding.The noise of small-sized needle rotor fluid delivery system can be near about noise of motor 65dB (A), and the noise of large-scale needle rotor fluid delivery system can be controlled at the level of noise of motor.And the minimum normal running noises level of conventional impellers blower fan is 85dB (A), and the highest normal running noises level can reach 130dB (A).
(6) in the running, if the gas of carrying contains the wearing and tearing material, then the wearing and tearing of pin seedling progressively and evenly develop to the lining from table.Wearing and tearing do not influence the pinwheel dynamic balancing.The pin seedling will be opened from the position ring that is scattered naturally week radiation cloth in start-up course, equals to stand the shake effect, so but on the pin seedling coherent substance limited.
(7) the pin seedling can be changed, so prolong the service life of blower fan.
(8) be provided with after the layering blanking structure, because the little and fluid stable of eddy current in the flow field that the pin seedling forms, double braid covering needle rotor fluid delivery system has the performance of the separate solid particles more superior than fan impeller.
The present invention is as the beneficial effect that compressor can produce the same (1)～(5) point.
The present invention can produce following beneficial effect as the centrifugal pump of carrying liquid:
The fluid proterties of liquids and gases is identical.Owing to similar reason, it is superior and transmission efficiency is high, pinwheel starts that load is little, pinwheel dynamic balancing realization and the high beneficial effect of grade naturally easily that the pinwheel centrifugal pump also has pinwheel energy transfer mode.
In addition, conventional centrifugal pump generation cavitation provides to bubble with leaf road vortex and to converge target, and spacing is big and provide sufficient bubble to converge the space direct relation is arranged between the impeller.Pinwheel is owing to gap between the pin seedling spatially is communicated with fully, and the pin seedling gathers, and spacing is also very little, does not possess the local asymmetric possibility that converges and increase of bubble.So pinwheel Cavitation Occurred in Centrifugal Pumps problem has obtained abundant solution.
