Description of drawings
Illustrated a comparatively desirable embodiment who proposes as structural principle of the present invention (agent structure of second the leakproof improvement project that continues with hereinafter intermediary).
1: dragging motor; 2: the metallic seal shell; 3: rotating shaft; 4: common air pump (for example: leaf type commonly used); 5: outlet pipe; 6: suction tude; K: tube wall hole or the position of tube wall hole is set.
Embodiment
Structure of the present invention is not very complicated; Its manufacture difficulty compared with prior art we can say just the same with relevant various technical requirementss; Its key is: on the architecture basics of conventional and common existing air pump 4; Increased by one and surrounded the former metallic seal shell 2 and supporting technological behave with three-dimensional form, can be when realizing in varying degrees preventing the present invention to move the leakage of gas, even finally can also realize the possibility of preventing gas molecule from the present invention, to leak.
First leakproof improvement project of the present invention can see claim of the present invention principal claim (claim 1) narration and with reference to the signal of Figure of description:
Metallic seal housing 2 the two overall structure form that constitute by air pump 4 and adapted with three-dimensional form encirclement air pump 4.---do not allow the suction port of air pump to be exposed in the middle of this shell inner cavity
General gas all can liquefy under given conditions, if what pass through in this air pump 4 is effumability gas; And this effumability gas is easy to liquefy under suitable condition, so, and when this effumability gas leaks in the inner chamber of this shell 2 from the axle envelope of the above-mentioned rotating shaft 3 of air pump 4 after; Although it is difficult to continue to have got into airspace again, yet being closed in these housing 2 these inner effumability gases is the possibilities that have liquefaction; And possibility is very big, and if things go on like this, this leakage pump is closed in the effumability gas in these housing 2 chambeies; Will inevitably liquefy, and should the liquefaction situation can take care of the pence, last; Let dragging motor 1 be immersed in the middle of this liquid, make it final the damage and shut down.
Therefore, first leakproof improvement project of the present invention has promptly only increased metallic seal housing 2 seals up air pump 4 with three-dimensional form structural type; So; Like this using scope of the present invention of structure, be merely able to only be limited under normal temperature condition, be difficult for liquefying (should be to liquefy) gas (for example: the air that does not contain moisture), otherwise; Careless slightly, will cause damage of the present invention.
Second leakproof improvement project of the present invention is on the basis of claim principal claim of the present invention, adds the two combination of claim 2 content description afterwards, and sees the signal of Figure of description for details:
Be arranged in suction tude 6 on the tube wall of this shell 2 inner chambers part, be provided with hole K, can see the particular location of the hole K that illustrates in the Figure of description for details.---let the suction port of air pump 4 be exposed in the middle of these shell 2 inner chambers limitedly.
The pressure of the high velocity air that in this suction tude 6, is caused by air pump 4 can be lower than the gas pressure of these suction tude 6 outsides; Promptly can be lower than and leak and be stored in the gas pressure that remains static comparatively speaking in these shell 2 chambeies; Should continue to leak the gas that comes out and will be to the drains get into constantly in the middle of the above-mentioned suction tude 6 from air pump 4 is inner through hole K; And mix with wherein high velocity air; Together by air pump 4 inspirations, another discharge after pressurization has again been accomplished with this: the processes that the gas that is come out by air pump 4 inner lasting leakages oneself is all reclaimed by air pump 4 again then.
Near the high velocity, low pressure district that this high velocity air can form the hole K in this suction tude 6 continues to attract above-mentioned natural power sources from air pump 4 inner continuous gas leakages to create condition for causing to this hole K is outside; General gas all can liquefy under given conditions; Owing to can form the high velocity, low pressure district near the hole K in this above-mentioned suction tude 6; Still through this hole K, the gas that is easy to liquefy for the static relatively of continuous leakage can also play the effect of urging its gasification and being easy to reclaimed again by the present invention use; The about 1/10 to 1/5 just enough of its suction tude 6 bores generally can be got in the aperture that this hole K is set, because the quantity of general gas leakage can be very not big, otherwise itself just there have been quality problems in air pump 4.
In addition; What get when air pump 4 pumps is effumability gas (also be easy to liquefaction); From the effumability gas of air pump 4 internal leakages owing to receive the low-pressure suction that is arranged on suction tude 6 tube wall upper opening K; Only can urge it and be easy to volatilization more, can not in these shell 2 inner chambers, cause the liquefaction of this effumability gas.
Obviously; Hole K is set on the tube wall of suction tude 6; Strengthen practicability of the present invention or Applicable scope, and realized at this point: both allowed air pump 4 gas leakages, still; This gas that does not allow again to leak might get into airspace, has also guaranteed: the gas of this leakage can damage dragging motor 1 in no instance.
The 3rd leakproof improvement project of the present invention is on the basis of claim principal claim of the present invention, adds the content after the two combination of claim 3, and its agent structure also can be with reference to the signal of Figure of description:
Suction tude 6 is arranged in the part of metallic seal shell 2 inner chambers, i.e. the part that the belong to suction tude 6 whole amputation of the suction port of these shell 2 internal chamber walls and air pump 4 between the two.---let the suction port of air pump 4 be exposed to fully in the middle of these shell 2 inner chambers.The mechanism of its anti-leak and function and above-mentioned second anti-leak improvement project are similar.
Because the intakeport 7 of air pump 4 is to be open in fully in the Seal cage of metallic seal shell 2 among the present invention, when high velocity air got in the chamber of these shells 2 from suction tude 6, the air-flow section can enlarge suddenly significantly; Its gas flow rate will subtract greatly suddenly; And when this air-flow got into the suction port 7 of air pump 4, because the bore of the suction port 7 of air pump 4 dwindles suddenly again, its gas flow rate can increase severely suddenly again; This process will inevitably produce very big " throttling " loss; And solve the effective technology means of this " throttling " loss problem, and be exactly the gas flow rate that reduces through air pump 4, promptly become original high velocity air and get final product into middling speed air-flow or low speed flow.
Therefore, structure like this of the present invention is suitable for processing gas flow rate air pump type on the low side most.
---the following problem that continues textual criticism above-mentioned " gas that does not allow to leak might get into airspace " again, promptly what problem is this degree that " does not allow " reach:
As everyone knows; It is not all right that bicycle and automobile a period of time do not inflate; This has just explained a problem fully: the seal degree such as the nonmetal sealing material of one type on rubber is not high; At least can not stop air molecule from the penetrating of this nonmetal sealing material, the speed that just penetrates is slow.If above-mentioned metallic seal housing 2 is to utilize the nonmetal sealing material such as one type on rubber to seal in its piece position with the way that the pipe vicinal that contacts with it is put employing; Or let the pressing piece between the metal covering of extremely bright and clean (bright and clean more also is that roughness is arranged) handle, can realize anything but that all stopping gas molecule therefrom penetrates.And see conversely, if realized stopping the possibility that gas molecule therefrom penetrates, reached degree the penetrating that stops from molecular level exactly to the sealing defence line.
The 4th leakproof improvement project of the present invention (reaching the degree that stops gas leakage from molecular level); Be above-mentioned first, on second basis with the structural solid of the 3rd leakproof improvement project; Increase the content of claim 4 again; Just can realize, promptly form above-mentioned corresponding three to stopping the improvement project that gas molecule leaks:
Put with the pipe vicinal in the splicing slit that lets metallic seal shell 2 relate to all is to realize through welding procedure.
Although getting into, rotating shaft 3 is easy to leak air pump 4 gas inside when the interior axle envelope of air pump 4 bodies is in air pump 4 operations; 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 that lets the gas of this leakage might continue to get into airspace.Leakage problem possibly be indifferent for the air of cheapness, yet, just not insignificant for some valuable gas leakages or supervirulent gas leakage, although the speed of its leakage is very slow.
So far; The key concepts that more should be appreciated that structural design of the present invention is: allow this air pump 4 inevitably from its internal leakage gas; But, do not allow structurally might to let this gas of leaking continue again to get into airspace and cause waste or harmful effect (gas that refers to costliness or severe toxicity).
What the present invention relates to is the most general and the simplest water pump industrial products belong to least flimsy industrial products in the using process, has created condition for realizing its non-removable welding procedure; Its suitable category more should be conspicuous; Therefore, we can say that by the most high-grade formed product of anti-leak means (welding), its practicability is the strongest according to the present invention, and, also have very high " cost performance ".
