Detailed description of the invention
The structure of the present invention is not the most complicated, and its manufacture difficulty requires compared with prior art may be used to relevant various technology
Just the same to say, it it is critical only that: on the architecture basics of conventional and common existing air pump 4, adds one with solid
Form surrounds the former metal sealing shell 2 and supporting technology behave, can realize to varying degrees preventing the present invention
The leakage of gas during operation, the most finally can also realize preventing the probability that gas molecule leaks from the present invention.
First leakproof improvement project of the present invention can be shown in chatting of the principal claim (claim 1) of the claims in the present invention
State and the signal of reference Figure of description:
The overall structure being made up of both the metal sealing housings 2 with stereogenic encirclement air pump 4 of air pump 4 and adapted
Form.The air inlet not allowing air pump is exposed in the middle of this shell inner cavity
General gas, the most all can liquefy, if pass through in this air pump 4 is effumability gas,
And this effumability gas is easy to liquefaction under suitable condition, then, when above-mentioned from air pump 4 of this effumability gas
After leaking at the axle envelope of rotating shaft 3 in the inner chamber of this shell 2, although it is difficult to be further continued for entering airspace, but, quilt
Being enclosed in this effumability gas within this housing 2 is the possibility that there is liquefaction, and probability is very big, if things go on like this, and should
Leakage pump is closed in the effumability gas of this housing 2 intracavity, will necessarily liquefy, and this liquefaction situation can take care of the pence,
Finally, allow dragging motor 1 be immersed in the middle of this liquid, be allowed to finally damage and shut down.
Therefore, first leakproof improvement project of the present invention, i.e. only increase metal sealing housing 2 by air pump 4 with vertical
The version that bodily form formula seals up, then, the range of the present invention of such structure, it is merely able to be only limited at room temperature bar
The gas (such as: do not contain the air of moisture) of liquefaction (should be to liquefy) it is difficult under part, otherwise, careless slightly,
May result in the damage of the present invention.
Second leakproof improvement project of the present invention is on the basis of the claims in the present invention principal claim, adds right
Require that the content after combination both 2 describes, and refer to the signal of Figure of description:
In air inlet pipe 6 is positioned at this shell 2 inner chamber on the tube wall of part, it is provided with hole K, can refer in Figure of description
The particular location of the hole K of signal.The air inlet allowing air pump 4 is limitedly exposed in the middle of this shell 2 inner chamber.
The pressure of the high velocity air caused by air pump 4 in this air inlet pipe 6 can be less than the gas pressure outside this air inlet pipe 6
Power, i.e. can be less than leakage the gas pressure remained static comparatively speaking being stored in this shell 2 intracavity, should be from air pump
The 4 internal gases persistently leaked out will be continued in the middle of above-mentioned air inlet pipe 6 by hole K to the drains, and
Mixing with high velocity air therein, the most together by air pump 4 inspiration, then another is discharged after being pressurized, completes with this: by
The process that the internal gas persistently leaked out of air pump 4 is all reclaimed by air pump 4 oneself again.
The high velocity, low pressure district that this high velocity air can be formed about at the hole K in this air inlet pipe 6, for causing this hole
The above-mentioned natural power source from the internal constantly gas leakage of air pump 4 is persistently attracted to create condition outside K；General gas is spy
All can liquefy under conditions of Ding, owing to high velocity, low pressure district can be formed near the hole K in this above-mentioned air inlet pipe 6, or
By this hole K, the gas geo-stationary of constantly leakage being prone to liquefaction can also play its gasification of rush and be prone to by
The present invention reclaims the effect of use again；The aperture arranging this hole K typically can take the 1/10 to 1/5 of its air inlet pipe 6 bore
Left and right is sufficient to, because the quantity of general gas leakage will not be very big, and otherwise, air pump 4 inherently exists quality problems.
Additionally, be effumability gas (be also easy to liquefaction) when air pump 4 pumping, volatile from air pump 4 internal leakage
Property gas owing to by being arranged on the low-pressure suction of air inlet pipe 6 tube wall upper opening K, only can promote it more easily volatilizees, it is impossible to
The liquefaction of this effumability gas is caused in this shell 2 inner chamber.
Obviously, the tube wall of air inlet pipe 6 arranges hole K, enhance practicality or the scope of application of the present invention, and with regard to this
Achieve: both allowed air pump 4 gas leakage, but, the most do not allow this gas of leakage to be likely to enter airspace, also assure that
: the gas of this leakage can damage dragging motor 1 in no instance.
3rd the leakproof improvement project of the present invention, is on the basis of the claims in the present invention principal claim, adds power
Profit requires the content after combination both 3, and its agent structure can also be with reference to the signal of Figure of description:
Air inlet pipe 6 is positioned at the air inlet two of the part in metal sealing shell 2 inner chamber, i.e. this shell 2 internal chamber wall and air pump 4
The part belonging to air inlet pipe 6 between person all amputates.The air inlet allowing air pump 4 is fully exposed to this shell 2 inner chamber and works as
In.The mechanism of its anti-leak is similar with above-mentioned second anti-leak improvement project with function.
Owing in the present invention, the air entry 7 of air pump 4 is to be open in completely in the annular seal space of metal sealing shell 2, at a high speed
Air-flow is when air inlet pipe 6 enters the intracavity of this shell 2, and air-flow section can expand the most significantly, and its gas flow rate will be dashed forward
So subtract greatly, and when this air-flow enters the air inlet 7 of air pump 4, owing to the bore of the air inlet 7 of air pump 4 reduces the most suddenly, its gas
Rate of flow of fluid can increase severely suddenly again, and this process will necessarily produce the biggest " throttling " loss, and solves this loss problem that " throttles "
Effective technology means, it is simply that reducing by the gas flow rate of air pump 4, the high velocity air i.e. becoming original is middling speed air-flow or low speed
Air-flow.
Therefore, such structure of the present invention is best suited for making the air pump type that gas flow rate is on the low side.
Below it is further continued for investigating the problem of above-mentioned " gas not allowing leakage is likely to enter airspace ", i.e.
This degree " not allowed " reaches how many problems:
It is known that it is not all right that bicycle and automobile a period of time do not inflate, this just sufficiently illustrates a problem:
Such as the seal degree of the nonmetal encapsulant of rubber one class is the highest, and air molecule at least can not be stoped from this non-gold
Belonging to penetrating of encapsulant, the speed simply penetrated is slow.If above-mentioned metal sealing housing 2 its piece position and and it
It is that the nonmetal encapsulant utilizing such as rubber one class seals that the pipe vicinal of contact puts the way of employing, or allows extremely light
Pressing piece between the metal covering of clean (the brightest and the cleanest is also to have roughness) processes, and is all absolutely not to be capable of stopping gas
Molecule therefrom penetrates.And see in turn, stop, if achieved, the possibility that gas molecule therefrom penetrates, it is simply that reached to stop
Penetrate sealing defence line from the degree of molecular level.
4th the leakproof improvement project (reaching from molecular level to the degree stoping gas to leak) of the present invention, is upper
State first, second with the structural solid of the 3rd leakproof improvement project on the basis of, be further added by the content of claim 4,
Can be realized as, i.e. formed above-mentioned corresponding three to stop gas molecule leakage improvement projects:
It is all to be realized by welding procedure that the splicing gap allowing metal sealing shell 2 relate to is put with pipe vicinal.
Although the axle envelope that rotating shaft 3 enters in air pump 4 body is in when air pump 4 runs the gas being easy to leakage within air pump 4,
But, the gas of this leakage can be enclosed in its cavity by this housing 2, and in the inner chamber enclosed construction of this " hermetically sealed " type,
There is not the chance allowing the gas of this leakage likely go successively to airspace.Leakage problem can for cheap air
Can be indifferent, but, the gas leakage valuable for some or the leakage of supervirulent gas, the most not insignificant, although
The speed of its leakage is the slowest.
So far, more should be appreciated that the key concepts that present configuration designs is: allow this air pump 4 inevitably from it
Internal leakage gas, it does not allow the most likely allow this gas of leakage be further continued for entering airspace and causing
Waste or harmful effect (referring to the gas of costliness or severe toxicity).
The present invention relates to the most general and simplest air pump industrial products, the most flimsy during belonging to use
Industrial products, create condition for realizing its non-removable welding procedure；Its applicable category, more should be apparent from；
It can thus be stated that the product formed by the most high-grade anti-leak means (welding) according to the present invention, its practicality is the strongest,
Further, also there is the highest " cost performance ".
