Description

Using fluid jacking external world water body enter with it is being capable of deep diving and can also exempt from periodically Bank excludes the simple type immersible pump that infiltration is safeguarded

Technical field

The present invention relates to immersible pump technology more particularly to it is a kind of using fluid jacking external world water body enter with being capable of deep diving Water and can also exempt from periodically debark exclude infiltration safeguard simple type immersible pump.

Background technology

At present, the various specifications immersible pump different from model emerges in an endless stream, however, they can only structure be positioned away from the water surface very Near position uses, moreover, make after using for a period of time under water, such as：It must typically debark after a few weeks or months The immersible pump is safeguarded, main purpose is：By dismounting, the water body inside penetrating into is removed.--- the infiltration is once long-pending Tire out the degree contacted with rotor, may result in spin down, the excessive last damage motor of electric current.--- it is obviously, existing " the big problem " of the immersible pump waterproof sealing of technology never solved, therefore, immersible pump diving it is deeper, it is necessary to it is regular Disembarkation row place seep water and safeguard (not being not to repair) time cycle it is short, to find out its cause, essentially consisting in：

The waterproof sealing element used in immersible pump is the macromolecule flexible material system utilized as based on rubber or plastics Into the sealing rings of various specifications serve as, however, the sealing ring that utilizes can not be resisted including water and air The possibility that fluid is therefrom passed through with the magnitude of molecule：

Bicycle tube with automobile tire is non-aerating for a period of time to use, this is just sufficiently illustrated：It should Manufactured flexible inner tube or tire based on high molecular material rubber or plastics are can not to resist the air as fluid to divide What the magnitude of son was therefrom passed through, it is clear that：Based on high molecular material rubber or plastics in manufactured flexible piece or block Gap between molecule is more than the diameter for forming air molecule, and only air molecule is passed through between the high molecular material molecule Gap rate can slowly some.

The phenomenon that passing through daily life or experiment can also prove：As the fluid molecule of fluid, equally can also pass through with The waterproof sealing defence line that manufactured any flexible piece is formed based on high molecular material rubber or plastics, only this pass through Rate also can slowly some.If --- the deep-fried twisted dough sticks food bought with polybag placement, soon, it can be seen that on deep-fried twisted dough sticks Oil can be exuded to the outside of the polybag, why human eye can find the phenomenon that oil can leak on the outside of polybag, be Because as the oil of liquid, belong to the substance for being not easy to volatilization, the oil molecule of the leakage that leaks easily in liquid form can be after Its form on the outside of polybag that leaks is stayed in continuation of insurance；But it if containing water in polybag, leaks on the outside of polybag Hydrone can be disappeared in human eye sight in the form of evaporation immediately.

In view of the present situation of currently available technology immersible pump, people are difficult to excessive demand and use extra heavy immersible pump (weight Can be very big), because it is difficult to timing lifting disembarkation exclude the maintenance (not being repair) of infiltration regularly.

Invention content

The purpose of the present invention：

Exactly in order to thoroughly solve immersible pump these three major issues to be solved：Extraneous water body cannot be introduced into, diving depth Infinitely with exempting from draining maintenance of debarking.

The key of the present invention is：

The prior art is just to bypass using above-mentioned " the entity member made based on " rubber or plastic flexible material " The technology behave of part " and its " structure of adapted " tackles and thoroughly solves above-mentioned three major issues.

The features of the present invention：

First, due to forming in " full seal type " complete machine structure of the invention, i.e., the gold formed by metal sealing Isolated Shield Belong in seal isolation cavity, be all (being used as existing of being realized by non-removable welding procedure between all seaming positions The soldering reliability for having technology thoroughly solves), this just for allow be lighter than water and incompressible fluid can be at this From top to bottom realize that its jacking external world water body is intended to the pressure from bottom to top internally permeated by electric machine shaft gland position in invention Or greatly osmotic pressure (diving is deeper should be also bigger by the upward osmotic pressure in electric machine shaft gland position) creates condition.

If --- the present invention is given under water horizontal positioned, then, circular axle envelope position is also inevitable in the present invention Can be horizontal positioned, which will necessarily just be higher than the circular top external world water pressure, then the circle Lower part external world water body (extraneous water pressure is more slightly higher) calmly will be penetrated by the axle envelope position present invention metal it is close It seals in isolated chambers, and the fluid in the cavity is squeezed out this from the top of round axle envelope position (extraneous water pressure is more slightly lower) Invention, consequence are exactly the corrupted that rotor is allowed to slow down and causes the motor, and specific reason is referred in " specific embodiment " " two, " money explanation.

2nd, due to being filled with fluid between the stator and rotor in the present invention, although relatively to its rotating speed compared with air Some resistances (can suitably slow down) can be caused, as long as however, the present invention to match to be used in be not very big underwater for speed demand On utensil, whole giving full play to for electric energy efficiency is not have much influences, is only limitted to the shadow for limiting rotary speed It rings.

--- what if the high speed torque or low speed torque needed in practical application can be a kind of by such as gear-box Speed changer realizes that this has become the very ripe prior art to adjust.

3rd, it due to being provided with dedicated oil-filled mouth in the present invention, also, is provided in far from metal sealing isolated chambers top The bottom position in portion, this just for can open oil-filled mouth that (filling fluid) can close and (block oil circuit) this can not prevent fluid molecule with When can pass through the ad hoc body (element) of (only rate unhappy), it is impossible to formed oily in above-mentioned metal sealing isolated chambers The gap of fluid molecule is leaked on periphery or upper position of the liquid other than its bottom or channel creates condition.

--- it is of the prior art, such as the waterproof grommet made of flexible high molecular material and its adapted of immersible pump Compressing structure, just the periphery in the overall structure of the immersible pump or top, which form, can not prevent fluid (gas or water) molecule The gap that can be passed through or access (it is unhappy only to pass through rate)：

Under the compressing of extraneous high-pressure water body, hydrone will necessarily pass through anti-the waterproof sealing element of the immersible pump bottom Water-stop element enters in submersible pump body, while during extruding, and the air molecule on internal top is allowed to pass through the anti-of top In the low pressure water body that watertight construction leaks to outside submersible pump body.--- it should be not difficult to find out in the process：It is that the prior art is caused to dive Water pump is unable to deep diving and must periodically debark carry out the root for excluding the two big defects that infiltration is safeguarded, and：Diving depth is got over Greatly, then the cycle time for being somebody's turn to do " regular " is shorter.

4th, since the present invention can thoroughly solve above-mentioned three major issues, this just dives for desirable superpower Water pump type (such as：Up to a million kilowatts) and no matter immersible pump need it is more deep slip into (such as：Upper km is deep) be all can be with " easy to implement " creates condition under the premise of non-maintaining.

Specific embodiment

In order to realize the above-mentioned purpose of the present invention, intend using following technical solution：

The present invention includes：

The motor being made of both rotor 2 and the stator 1 of embedded winding of conventional structure form simultaneously passes through its shaft 6 The liquid pump 9 of dragging lower part is run；

It is characterized in that：

Rotor 2 is at least allowed to be surrounded with stator 1 by wide type metal sealing Isolated Shield 5 with stereogenic, also, in width The bottom of type metal sealing Isolated Shield 5 is provided with the shaft 6 that can be passed down through electric machine shaft gland 7；

Wide 5 bottom of type metal sealing Isolated Shield by pipe joins or is directly provided with oil-filled mouth D；

The fluid being filled in the wide type metal sealing Isolated Shield 5；

All splicing gaps that the wide type metal sealing Isolated Shield 5 is related to all are by non-removable welding Technique realizes connection.

The fluid is less than 0 DEG C of low-freezing lightweight (not easily causing deceleration) oil.

The wide type metal sealing isolation 5 is to have carried out gap with liquid pump 9 by dismountable 10 fastener of screw to determine Position；

Or：

The wide type metal sealing isolation 5 is to be carried out continuously with liquid pump 9 by non-removable welding procedure to realize Gap positioning.--- the structure is easily formed：The hydrone in liquid pump 9 will not be externally leaked during present invention work.

The manufacturing method of the present invention：

It is characterized in that, before referring to that rushing oiling liquid P (when being not yet connected with liquid pump 9) for self-existent motor terminates Finally consolidate full of program processing method：

Refer to self-existent motor is completed generally conventional being considered as be filled with it is attached after the program of fluid P Add " consolidation " filling program of reprocessing property：

The axle envelope 7 of dragging motor is looked up into placement, then slightly shake a moment (about ten times or so) upwards, finally by oil-filled Mouth D to complete machine pressurize (such as：5 atmospheric pressures) again row filling fluid P, at the axle envelope 7 of the inverted dragging motor send out The existing fluid P to leak occurs, you can assert to complete expires the process of filling to motor filling fluid P.--- electricity is ensured with this measure Machine leaving no air bubbles inside is simultaneously filled with fluid P really.

It is explained the main points briefly and the signal of Fig. 1 according to above, it should substantially be appreciated that the mechanism of the present invention, below Related keyword particular problem when implementing again to the technology of the present invention is further described：

First, the present invention relates to " hermetically sealed " type structure problems of metal sealing Isolated Shield cavity：

Both wide type metal sealing Isolated Shield 5 surrounds rotor 2 and stator 1 wherein, thickness can use 2 millis Rice；Gap between wide 5 different parts of type metal sealing Isolated Shield must be realized, and should be tight using welding procedure There is the phenomenon that rosin joint or dry joint (avoid rosin joint or dry joint technically very ripe) in taboo.

Since the gap formed between metallic molecule is less than the diameter of air molecule or hydrone, metal sealing every From the structure that shielding cavity is formed " hermetically sealed " type, air molecule or hydrone can be prevented therefrom to pass through；It is and above-mentioned The sealing ring or structure of various specifications made of the macromolecule flexible material based on rubber or plastics are absolutely not resistances Only air molecule or hydrone therefrom pass through.

If some position of the metal sealing Isolated Shield cavity in the present invention is using dismountable nonmetallic rubber Or the flexible macromolecule sealing material of plastics one kind implements sealing by the fastening of bolt, then, it is not likely to form " complete The three-dimensional defense line of sealing " type, because it can not possibly prevent air molecule with hydrone from passing through, and only it is possible to pass through rate for it It can be slow.

If some position of the metal sealing Isolated Shield cavity in the present invention is using dismountable two non-ordinary lights Sliding metal flat implements sealing by the fastening of bolt, then, the solid that it is also impossible to be formed " hermetically sealed " type is prevented Line, because, then smooth plane all has " roughness ", it is equally also impossible to that air molecule is prevented therefrom to wear with hydrone More, only its rate passed through may be slowly.

More than two " if " example fully demonstrate used why in the prior art in its key position it is removable The above-mentioned sealing element and its structure unloaded can not resist gas molecule or fluid molecule and the reason penetrated in defence line is sealed from it.

So far, it should it is very clear, exactly because the present invention employs crucial simple metal seal cavity and realizes Oneself " hermetically sealed " type three-dimensional defense line, and the penetration problem that can prevent air molecule and hydrone is ensured with this.

When present invention employs the designing scheme full of fluid P, purpose is that：The fluid P that will not be compressed is allowed at this Invention is internal, premised on itself can never be leaked due to " hermetically sealed " the type defence line of formation, it will be able to where prevent the external world I guess high water body pressure is for the osmotic pressure inside the present invention.--- it is (aobvious that if internal fluid P has approach that can leak Do not have so), then, extraneous high-pressure water body will permeate up into (obviously from 7 position of axle envelope of metal sealing shielding cavity Can not possibly).

2nd, the present invention relates to using internal hydraulically full (fluid P) scheme is allowed the problem of：

In view of knowledge：If original design is exactly to allow in motor that water body can be filled with, then, due to water body Can be conductive, therefore, water body is great for the rotating speed influence of rotor 2：

One is：Since water body can be conductive, rotor 2 can cause it week to make a circle the counter electromotive force of water body formation when rotating And the influence that rotor 2 is significantly allowed to slow down is caused, the electromotive efficiency of complete machine can also give a discount；

The second is：Water body will result in the shadow significantly to slow down to rotor 2 in rotor 2 and stator 1 in itself between the two It rings.--- with air in rotor 2 compared between the two it is self-evident with stator 1.

Therefore, the design of general motor, it is most using allowing rotor 2 with stator 1 under conditions of full of air Allow rotor 2 can high-speed rotating efficient design scheme, however, rotating speed is caused to become once rotor 2 is allowed to touch water body at this time Slowly, it causes overcurrent phenomenon and damages motor.

If it is exactly deliberately to employ nonconducting fluid P full of the structure type institute inside motor as the present invention The motor of design, then, nonconducting fluid P can only cause the rotating speed of rotor what is slowed down between rotor 2 and stator 1 It influences, and much can always be influenced less than the deceleration caused by above-mentioned water..

If when the motor of filling fluid P is exactly the underwater utensil that is run for non-high-speed, such as：It is exactly for adapted During underwater conveyer belt, then, fluid P is filled with, the influence for the underwater dragging motor is only limited to rotating speed decline, and Conveyer belt does not require natively quickly to run, and this point conforms exactly to therewith.--- however, at this time once the present invention in fluid P has changed water body (necessarily by can just form the infiltration of extraneous water body under the premise of the original fluid P in part has been squeezed out) into, that , the water body of the infiltration can equally cause the motor speed relatively slack-off and finally result in the consequence of motor damage.

--- according to above-mentioned analysis and common knowledge, be not difficult it is small bear, exist between the rotor and stator of dragging motor It is also different that different media, which influences the rotating speed of rotor,：

If in vacuum state, the speed reduction influence of rotor is not present；

If being filled with air, (air drag influences rotating speed little) minimum for the speed reduction influence of rotor；

If being filled with fluid P, (viscosity of fluid P has an impact rotating speed) bigger than normal for the speed reduction influence of rotor；

If being filled with water body, (viscosity of water body has an impact rotating speed) bigger than normal for the speed reduction influence of rotor, however, right In rotor speed reduction influence maximum element still since water body can be conductive, rotor causes to lead between rotor and stator when rotated Electric water body can also charge and (generate counter electromotive force), this is likely to reach significantly degree for the influence that rotor slows down, i.e., It is likely to the limited influence for deceleration much larger than above-mentioned water body viscosity.

3rd, the present invention relates to the stator of underwater adapted motor can dismounting and change the problem of：

As shown in Figure 1, motor stator 1 is isolated with rotor 2 by metal sealing Isolated Shield cavity between the two, It can independent dismounting and change so that becoming relative to the motor stator 1 for having surround winding that is easily damaged；Due to such motor Structure manufacture is cumbersome, only has only a few to employ such knot that can replace stator 1 at present, in prior art motor product Configuration formula, however, for as underwater adapted motor (particularly with powerful heavy machine), unlike easily whole on the ground Machine replace, therefore or the consideration that should should be regarded as a different matter or use the ideal structure for being capable of dismounting and change stator 1 to be appropriate, this It is also beneficial to extend the service life of the underwater adapted motor body part simultaneously.

As shown in Figure 1, both motor stator 1 and rotor 2 are shielded by metal sealing Isolated Shield cavity, once Comparatively the winding on motor stator 1 being easily damaged goes wrong, need dismounting and change motor stator 1 be it is not all right, only Entire dragging motor can be changed；However, such dragging motor can bring many convenience in the manufacture of itself, It is all form with such a structure to cause the prior art overwhelming majority.

In summary：

In general, motor is a highly developed product, as long as ensuring that rotor 2 therein is in fluid P always Middle rotary work, then, motor is just less likely to be damaged.Therefore, by the rotor 2 in the present invention be arranged on metal sealing every Off screen covers intracavitary and does not also just have to worry easily occurring after long-term operation from the problem of damage.--- it is driven by motor drag Durable instrument, such as：Washing machine, refrigerator and sky wither device, etc., typically up to target adapted prior art dragging motor conduct The utensil of output component, the maintenance-free disposable adapted service life greatly can be at 15 years or more, and World Famous Brand is then reachable By 30 years or more, if being produced again using best material, the serious hope maintenance-free disposable adapted service life may be more than 50 years.For this purpose, non-removable welding procedure is employed to implement its " full seal type " in belonging to the present invention of simple products During structure (prevent product is from carrying out demolition and maintenance), time limit of the people for the present invention disposable service life is not interfered with.
