In empty situation, jet pump may replace liquid-ring type, rotary vane type, reciprocating vacuum pump.
The research and application of jet pump have had very long history, and most earlier than 16th century, people just have found the mixed of jet stream
Close phenomenon.With hydrodynamics and Aerodynamics and the development of application, fluidics also obtains very big mention therewith
It is high.Jet pump is as a kind of common apparatus that can produce great economic benefit, it has shown that in human economy life
Increasingly important role.Fluidic nozzle configurations do not disappear as a kind of basic and easy physical transport mixed method for many years
Medicament is consumed, it is always the hot spot of domestic and foreign scholars' research that without secondary pollution, operation and maintenance cost is low, therefore, expedites the emergence of out more height
Imitate energy-efficient jet nozzle patent of invention.These result of design are applied in the petroleum of developed country, chemical field.
Currently, developed country has obtained a large amount of data through a large number of experiments and has obtained many patents, these patents for they with
Huge economic benefit is carried out.However, expected efficiency mechanism must be taken into consideration in the design of jet stream pumping system, this point is ground at present
In studying carefully not enough sufficiently;Both many factors for restricting jet stream efficiency are not understood in depth and jet stream sprays the machine being vacuum formed
Reason, the condition also formed without grasping best efficiency point, therefore, it is difficult to design highly efficient energy-efficient device.
Jet stream pumping system is that the swiftly flowing liquid sprayed with jet nozzle realizes the mesh conveyed to solid-liquid mixtures
Mark, in the process, jet pump nozzle material-feeding efficiency directly influences jet stream pump system efficiency, therefore, how to improve jet pump
The efficiency of system just seems most important.It is worth noting that whole efficiency of the jet pump nozzle material-feeding mouth distribution device to system
Also it can have a certain impact.Such as be added in jet stream Unit injector powder product (such as starch) humidity is excessive, wet weather causes
Powder humidity is excessive and operator's overfeeding can all cause the excessive heap of powder at the feed opening of jet pump jet nozzle inside
Product is blocking, is commonly called as " stick together material ", causes powder to cannot rely on self gravity and freely glide, can not generate in jet pump jet nozzle
Jetting stream vacuum under be inhaled into jet nozzle, cause jet stream pumping system dry run, i.e. generation jet nozzle efficiency bottle neck.Cause
This, in no jet pump nozzle material-feeding mouth distribution device, operator cannot use iron rod to be stirred cloth to powder
Material, because dust encounters open fire may when operator feeds to jet stream Unit injector there may be a large amount of dust in workshop
It sets off an explosion.Therefore, operator can only carry out cloth and dredging to feed opening bottleneck with waddy, this is just artificially increased
The investment of labor cost;Being also possible to, which causes sawdust to fall into product quality in hopper, is difficult to ensure.Therefore, traditional system design
Method does not carry out cloth synergy to jet pump nozzle interior feed inlet, causes the investment of a large amount of man power and material, and exist
Possible security risk, so that jet stream pump system efficiency reduces, it is not only uneconomical but also not environmentally.

It is few, the decrease of potential energy of liquid and kinetic energy increases, in this way, liquid is increased considerably by its jet velocity when the outlet of pumping chamber A,
Form jet effect.Swiftly flowing liquid is injected into diffusion type via vacuum mixing chamber B, and space hold volume increases, entrainment
Partial air enters expansion chambers C, and the spatial volume of liquid further increases, subsequently into the conveying isometrical with the outlet end of C
Pipeline.Swiftly flowing liquid generates vacuum during via pumping chamber A to expansion chambers C, and the powdery under free skating is consolidated
Body sucks mixing chamber, and enters expansion chambers C after mixing with the high-speed liquid continuously entered.Mixing liquid is returned via conveyance conduit
It sizes mixing and tank and is sucked again by highly pressurised liquid delivery pump, then squeeze into jet nozzle, form a circulation.

Be: jet nozzle has the characteristics that rotatability and unsymmetric structure, and therefore, it is true that it can produce periodically variable pulsation
Sky, and pulse vacuum will lead to solid powder and generate relaxation during entering jet nozzle and accelerate the unstable pulsation glided
State is not accumulated blocking so that powder can reach and be uniformly distributed before entering jet area, and good fluidity is avoided and " sticked together
Material ", and jet stream pumping system dry run is prevented, also prevent jet nozzle efficiency bottle neck.Traditional design method is silent
Recognizing flowing after solid powder enters in hopper is free downslide flow regime, jet stream Unit injector is directly entered, without to flowing
The distribution of powder carries out synergy in the process, causes wasting for a large amount of fluid dynamic energy and potential energy, but also system is imitated
Rate reduces.Intuitively show themselves in that be added in jet stream Unit injector powder product (such as starch) humidity is excessive, wet weather causes powder
Material humidity is excessive and operator's overfeeding can all cause powder excess accumulation at the feed inlet of jet pump jet nozzle inside
It is blocking, it is commonly called as " stick together material ", causes powder to cannot rely on self gravity and freely glides, can not be generated in jet pump jet nozzle
It is inhaled into jet nozzle under jetting stream vacuum effect, causes jet stream pumping system dry run, i.e. generation jet nozzle efficiency bottle neck.
