Power.Since impeller 51 is during rotation conveys air, the reaction force of air is pressed on impeller 51, and impeller 51 can crush
Onto bearing 8, and then it is be easy to cause 8 service life reduction of bearing, the thrust of impeller 51 can be effectively limited using positioning element 6, is made
Obtaining bearing 8 can rotate freely, and thrust is distributed to end cap 3, so that whole service life improves, work relatively reliable.
For Fig. 3, by taking function of increasing pressure as an example, air goes out to enter from two end caps 3, symmetrically converges to middle shell 4,
And therefrom second in shell 4 connects the discharge of port 41, realizes supercharging effect.
Further, refering to what is shown in Fig. 4, be provided in the air inlet face 521 of shell 52 axis hole 523 that is passed through for shaft 2 with
And it is arranged fluted 525 on the inner wall of air inlet 524, shell 52.Groove 525 has other than guide functions, can also be to dust
Accumulation there is apparent reduction to act on.
With reference to 51 structure of Fig. 5 and impeller shown in fig. 6.Impeller 51 includes circular substrate 511, is set to substrate 511
Axle bed 512 that center is connected for shaft 2, positioned at substrate 511 vortex leaf 513 of the first side centered on axle bed 512 and
Positioned at centrifugation leaf 514 of the second side centered on axle bed 512 of substrate 511；Vortex leaf 513 is arranged multiple equal around axle bed 512
Even distribution, forms convergence runner 515 between adjacent vortex leaf 513, centrifugation leaf 514 be arranged it is multiple be uniformly distributed around axle bed 512, phase
Centrifugation runner 516 is formed between neighbour's centrifugation leaf 514.The starting point of vortex leaf 513 and the side wall integrally connected of axle bed 512 are vortexed
The end end edge of leaf 513 extends to 511 edge of substrate.Air can be made effectively to reach in the groove 525 of shell 52.It is centrifuged leaf
514 with the gradually evolution of vortex leaf 513 to consistent.So as to keep the eddy flow direction of air consistent, air can be mentioned constantly
Speed and convey over.Impeller 51 plays the role of apparent vibration-inhibition and noise, work using centrifugation leaf 514 plus vortex leaf 513
It is more steady to make state.It can be seen that noise control can be obtained more preferably on the whole, quieter, the non-maintaining time is long, and needs
Less lubricating grease, more environmentally-friendly energy conservation.
For assembly method refering to what is shown in Fig. 4, centrifugation leaf 514 is located at the air inlet face 521 of shell 52, vortex leaf 513 is located at shell
52 outlet face 522.Wherein, the fluid of first side is gone out by centrifugation runner 516, excessively arrives second side by groove 525,
The fluid of second side enters from convergence runner 515.
The cooperation of the structure of impeller 51 and shell 52, so that in 51 rotary course of impeller, it will by the air inlet face 521 of shell 52
Air is divided into multiply, and air is displaced into the groove 525 of shell 52 using centrifugal force, then air is had first side flowing
Second side is converged air using the vortex leaf 513 in second side again, and the air after convergence can be for next pump
Body 5 carries out.
It is provided with 2,3 or 4 second on middle shell 4 and connects port 41, wherein second connects port 41 for connecting pressure release
Valve or water cooling equipment.In order to improve protective performance, the excessive centering shell 4 of pressure is avoided to cause to rupture, so that relief valve is arranged can
Upper pressure limit is effectively arranged, over-voltage is avoided.When the temperature is excessively high, can use second connect port 41 be passed through by water cooling equipment it is cold
But water, to reduce case temperature.
Connecing port 31 for the first of 3 position of end cap can connect air filter, and the work of filtering can be played to dust
With raising service life of equipment.It is fixed it should be noted that middle shell 4, shell 52 and end cap 3 are connected by bolt.
The course of work: motor 1 provides rotary power and rotates shaft 2, and being fixed on impeller 51 in shaft 2 will be
Rotation in shell 52, shell 52 are fixedly connected with, the multiple pump housings 5 series connection motionless relative to motor 1 with end cap 3.The peace of this air pump
Dress mode is fairly simple, is directly sleeved and fixed in shaft 2, assembles convenient efficient.When being used as function of increasing pressure, need to open
Dynamic motor 1, motor 1 drives the impeller 51 in the pump housing 5 to rotate at this time, since the conveying air of the pump housing 5 is unidirectional, sky
Gas goes out to enter from the end cap 3 at both ends, is converged in middle shell 4 by the air delivery of multiple pump housings 5, meets 41 row of port from second
Out, air does not pass through a pump housing 5, then air pressure all promotes a grade, and therefore, supercharging effect is stablized obvious.When being used as
When vaccum-pumping equipment, needs to carry out above equipment disassembly and reconfigure, i.e., the installation direction of the pump housing 5 is exchanged, air inlet and row
Gas direction is exchanged, then the new function of achievable equipment.At this point, due to the operation of the pump housing 5, so that therefrom shell 4 detaches air, warp
The pump housing 5 is crossed to be conveyed to two end caps 3, so as to which the air in the container for being connected to middle shell 4 is detached, similarly, on
The pump housing 5 stated can connect it is multiple, so as to which the ability for detaching air is continuously improved.
Certainly, above is representative instance of the invention, and in addition to this, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
