Description
Technical field
It the present invention relates to the use of the immersible pump (including immersion pump) of air jacking principle waterproof (liquid) sealing and again can
Enough at the same time operationally will not be to the pump configuration and its application method of fluid molecule in extraneous leakage pump.
Background technology
At present, the various specifications immersible pump different from model emerges in an endless stream, and is that quite extensive and maturation the one kind of purposes is moved
Power equipment, its deficiency are：Immersible pump relies primarily on its sealing structure (made of macromolecule flexible material various rule under water
The sealing ring of lattice serves as) resist extraneous water body for the infiltration inside immersible pump dragging motor.
For this reason, when people use immersible pump operation, the general service intervals time will not it is too long (few then a couple of months and at most
It is difficult to more than 1 year --- the service intervals time of the more big then immersible pump of diving depth is shorter), as long as after use, just must be periodically
It is left the water in ground safeguards (not being corrupted maintenance), allows the infiltration come into inside motor for submerged pump to have an opportunity by artificially
Remove in time, to avoid rotor touches growing number of infiltration and causes whole motor corrupted.--- compact submersible pump this
Sample repeatedly many times disembarkation safeguard water removal can still allow, can medium-sized, even Large diving pump so regularly from bank waterborne
Safeguard water removal, just there is trouble, or even have burden so that being difficult to be normally used it, such as：Tens of thousands of or hundreds of thousands is very
The medium-sized or Large diving pump of supreme megawatt is just difficult to enter or can not enter conventional product service stage；Study carefully
Its reason is exactly to be：Type is bigger, and diving is deeper, and " water removal is safeguarded in disembarkation " is just more difficult to, more frequent.
The reason for causing above-mentioned behaviour in service, mainly causing the service intervals time not long, is exactly the diving of the prior art
Waterproof sealing structure is pumped, i.e. crucial waterproof seal ring can not definitely be accomplished in design：Prevent air molecule or hydrone from
In the degree passed through, i.e.,：Extraneous hydrone passes through waterproof seal ring and gets into immersible pump, and by original air in immersible pump
Point passing through waterproof seal ring by force again is extruded immersible pump, it is clear that：Above-mentioned waterproof seal ring has functioned only as delaying air point
Son passes through the time of oneself with hydrone, thus is just difficult to：
Allow immersible pump to use under water always, be still placed under water, use under water again afterwards, once more after shutting down
Be placed in underwater ... ..., until form the immersible pump liquid pump or dragging motor alternative one (motor is easiest to bad in contrast
Damage) oneself cause corrupted after long-term work abrasion and shut down.--- i.e.：It is difficult to and makes immersible pump underwater always
In environment " throughout one's life ".
Furthermore can not yet it be asked at present directly for a long time in tens meters even immersion pump of the depth underwater work at hundreds of meters
Generation.--- because the prior art waterproof sealing structure of above-mentioned requirements to be reached not yet comes out.
In addition, any liquid pump, such as water pump, all it is to allow water pump outwardly to leak its internal water, but do not allow to surpass
Mark, otherwise, there is the quality problems of water pump.--- the prior art let alone allow water pump not allow to the external world operationally
The problem of leaking the hydrone of its inside.
The content of the invention
The purpose of the present invention：
Be exactly overturned first from structure the existing waterproof sealing link of immersible pump start with it is (former using the sealing of air jacking
Reason), and at the same time and solve the problems, such as in passing will not externally in leakage pump body water (liquid) molecule pattern handling.
In order to realize the above-mentioned purpose of the present invention, plan can use following technical solution：
The present invention includes in structure：
The shaft band that the dragging motor being made of the stator of rotor and embedded winding of conventional structure form passes through it
Dynamic liquid pump；
It is characterized in that：
First, at least allow rotor by narrow metal sealing to be isolated to surround with stereogenic, alternatively, at least allow rotor with
Both stators are isolated by wide type metal sealing to be surrounded with stereogenic, also, in the isolation of narrow metal sealing or wide type metal
The bottom of seal isolation is provided with electric machine shaft gland and inflation nozzle mechanism and pressure-display device interface；
2nd, at least form liquid pump around and bottom be with stereogenic bag by non-removable shape metallic leak-proof structure
Round, also, feed liquor interface tube and discharge opeing interface tube are provided with liquid pump；
The metal sealing isolated chambers isolated by narrow metal sealing or wide type metal sealing isolation is formed respectively,
It is to realize what is be connected by the welding procedure at non-removable welding circle position between shape metallic leak-proof structure, alternatively, being logical
Cross what dismountable screw was mutually located；
The narrow metal sealing isolation or wide type metal sealing isolation and shape metallic leak-proof structure are related to all
It is all to realize connection by non-removable welding procedure to splice gap.
--- it is described to allow rotor non-to be led using slim by the part that the isolation of narrow metal sealing is surrounded with stereogenic
Magnetic material serves as, also, narrow metal sealing isolation is local is in dismountable tight with the inner ring circumferential location of the stator
Mated condition.
The application method of the present invention, i.e. preparation method before use：
One of one, methods：If it is intended to pump being placed on the use of position below liquid level, first by inflating nozzle mechanism to liquid pump inside
Inflation, the pressure gauge connected by pressure-display device interface are observed, or otherwise feel (such as：Using beating manually
During cartridge inflation), when the blowing pressure be greater than or equal to pump the depth pressure to be slipped into after, it becomes possible to by the pump be put into liquid level with
Descending and being powered allows it to start work, at this time, the fluid molecule which will not be to pump external leakage inside the pump；
The two of two, methods：If being intended to pump being placed on the use of position below liquid level, it is allowed to be powered after startup work, the pump is same
Will not be to pumping fluid molecule of the external leakage inside the pump.
The features of the present invention：
One, due to the present invention in structure can by the inflation nozzle mechanism of setting to immersible pump inner inflatable (such as：Adopt
With simplest manual pump plenum), ensure that the immersible pump to work in the diving depth of sets itself can
The outside water with certain ambient pressure or very big ambient pressure is resisted in a manner of the internal gas jacking of required pressure
The infiltration of body, as utterly realizes immersible pump internal pressure and is more than (or equal to) extraneous water body and seeps water for complete machine inside and press
Power and the gas jacking pressure value that sets creates condition.--- and then established the present invention can be suitable for any diving deep
The immersible pump of degree work creates condition.
--- the critical defect of the prior art is：The internal pressure of an atmospheric pressure can only be used (to tie up in immersible pump
Environmental pressure when holding immersible pump manufacture) come resist it is extraneous be more than or much larger than an atmospheric pressure extraneous water body for latent
Inside water pump on the premise of seepage pressure, that is, rely solely on the macromolecule flexible water sealing member that fluid molecule can penetrate
The strength of part and it is invalid resist to carry out temporarily sealing in a short time, cause：The prior art must often (regular) disembarkation
Safeguard (main task be cleaning eliminate infiltration), moreover, diving depth is bigger, periodically debark cycle of maintenance of immersible pump gets over
It is short, that is to say, that, it is impossible to allow immersible pump to be constantly in the purpose realized in underwater environment " throughout one's life "；In order to regular
Ground hangs water surface maintenance, and the prior art is merely able to be adapted to manufacture to be operated in leave the close small pump of the water surface.
Two, are due to the metal isolated in structure of the present invention by narrow metal sealing or wide type metal sealing isolation is formed respectively
Cavity is sealed off, is that the welding procedure for enclosing position by non-removable welding is connected to realize between shape metallic leak-proof structure
, this will not just leak for the fluid molecule of the invention that can be realized at work inside the approach present invention and create bar
Part.--- in engineering, if some valuable liquid of pumping or during extremely toxic liquid under water, possessed height in this kind of engineering
It is required that, it is likely to its necessary or prerequisite can be used.
--- the critical defect of the prior art is：During normal work, this point, the national standard of water pump are not definitely accomplished
(including all countries) is typically all " allow leakage but can not be exceeded ".
In " full seal type " the complete machine structure forms of three, due to forming liquid pump special in invention and actuating unit, only
There is provided one positioned at metal sealing isolated chambers bottom and fluid molecule can be allowed to pass through electric machine shaft gland (only this
"one" is unavoidable in structure), however, not any other in complete machine structure can convey the fluid molecule
The gas molecule of same volume can also leave the seal isolation chamber in the case where penetrating into liquid extruding, i.e., gas molecule leaks logical
Road or gap, this is just the present invention in " full seal type " metal sealing isolated chambers in the case of the jacking of gas from top to bottom,
So that more than the extraneous highly pressurised liquid of specific gravity of gas, being definitely somebody's turn to do for the present invention can not be entered by passing through electric machine shaft gland from bottom to top
Seal isolation intracavitary creates condition.
--- the critical defect of the prior art is：Extraneous high-pressure water body can pass through the minimum above-mentioned electric machine shaft gland in position
The gas to apply pressure in pump, and allow in the pump by extraneous the extruded gas that seeps water pass through at a slow speed many places on electric machine shaft gland top by
The sealing that sealing element made of the flexible macromolecule class sealing material being embedded in dedicated optical coulisse gap structure is formed is three-dimensional
Defence line (gas molecule can not be stopped by sealing coil element to passing through outside complete machine --- to external leakage), when the water that the external world is penetrated into
Body will be contacted finally simultaneously after accumulating and progressively substituting the original occupied space of the gas being extruded with rotor
Cause its corrupted.
Four, in the present invention due to not having using the knot of the sealing element entity on conventional meaning and its adapted in the prior art
Structure, seals only with the gas jacking principle of sealing element entity is not required, will cause in overall structure existing
The integrally-built change of immersible pump or simplification, however, its sealing performance, which has but much surmounted the prior art, (has reached absolute
The degree of sealing), for this reason, " cost performance " of the present invention will necessarily be much larger than the prior art, this just for it is of the invention at least can be into
Regeneration product for prior art immersible pump creates condition.--- meanwhile, it is suitable for most common water pump structure.
--- the critical defect of the prior art is：Due to the sealing element entity set by it and its structure of adapted without
Method prevents penetrating for gas molecule or fluid molecule, and the purpose slowed down only up to transmission rate, i.e., internally seep water reduced rate
Some, therefore, on complete machine structure, finally wait its destiny, it is likely that are exactly that the structure of existing immersible pump can be allowed to be sent out by this
It is bright to eliminate.
Five, are since the present invention can slip into required any underwater depth position in engineering, and it continues under water
Time (contain：The time of work and the time of inoperative) it can reach infinitely great and (be excluded during this period without periodically disembarkation
The maintenance of infiltration), in this way, immersible pump of the present invention can as needed or manufacturing capacity makes required extra heavy machine
Type (such as：Up to a million kilowatts of power is made --- the prior art is not on your life), it is efficiently directly to be pumped under the rock stratum of deep-sea
The submarine oil adopted is taken away, alternatively, (not yet solving at present can be into efficiently to exploit " combustible ice " that is enriched on the earth under water
Enter exploiting on a large scale and for the method for commercial object for practical stage) create condition.--- the one of immersible pump of the present invention
The secondary underwater service life of property completely can depend on dragging motor service life (if World Famous Brand motor can reach 30 years ---
Its service life is produced using best material to can reach close to 50 years or longer).
--- the critical defect of the prior art is：Come as a result of the ring structure that soft high molecular material is produced
Waterproof sealing, can not prevent extraneous water body and penetrate into inside existing immersible pump and cause the damage of motor, dive under water in immersible pump on the contrary
It is deeper, then under the premise of the shorter weak tendency performance of the maintenance period of periodically disembarkation exclusion infiltration, if extra heavy diving is made
Pump is difficult to often disembarkation and carries out periodic maintenance to exclude to seep water.

For most will not corrupted and product with the long-life, especially for even more so for medium and small motor, as long as therefore will
4th constructive embodiment is used to manufacture medium and small product of the invention, does not just worry the dragging electricity of the present invention generally
The problem of being easy to corrupted of machine.
Explaining the main points briefly more than and the signal of relevant drawings, it should be substantially appreciated that the mechanism of the present invention
And it is general summarize, below for the related keyword particular problem involved by the implementation of the technology of the present invention remake as follows into
The explanation of one step：
The formation problems of the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield of the one, present invention：
In narrow metal sealing Isolated Shield 4, between its motor stator 1 and rotor 2 be provided with by it is slim (such as：Its thickness can
Take 0.1 millimeter) composition narrow metal sealing Isolated Shield made of non-magnet material (have drawn from stainless steel or brass, etc.)
4 overall Part portions；And other positions of the narrow metal sealing Isolated Shield 4 can be produced using thick and solid material,
The magnitude that its thickness is several millimeters can be taken (thickness in general small medium-sized immersible pump can use 2 millimeters)；And form and be somebody's turn to do
Gap between 4 different parts of narrow metal sealing Isolated Shield must be realized using welding procedure, and should forbid
Existing rosin joint or the phenomenon of dry joint (avoid rosin joint or dry joint technically very ripe), the narrow Isolated Shield 4 it is final into
Type can be realized using the method for implementing the last assembly of integral solder after local installation again.--- purpose is：Allow assembly
The narrow metal sealing Isolated Shield 4 afterwards forms one except its underpart electric machine shaft gland position 7 (can use conventional axis
Seal structure --- but the infiltration of water body can not be prevented) beyond monolithic devices can not be penetrated by gas molecule or fluid molecule are close
Metal cavity, the only metal cavity, that is, form the gap between the metallic molecule of the narrow metal sealing Isolated Shield 4, be
Less than the diameter of general gas flow molecule or fluid molecule.
Since both motor stator 1 and rotor 2 are isolated by narrow metal sealing Isolated Shield 4 so that relative to appearance
The flimsy motor stator 1 for having surround winding becomes detachable, but can suitably increase some hardly possiblies in manufacture
Degree.--- in contrast, both motor stator 1 and motor stator 1 are enclosed in it by wide type metal sealing Isolated Shield 5
In, it be manufactured just it is simple more, but so that relative to its motor stator 1 being easily damaged become it is non-dismountable more
Change, specific details are omitted it is clear that being described in detail.
" full seal type " problem of metal sealing Isolated Shield cavity involved in the two, present invention：
Since 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield belongs to employ metal sealing
The structure of Isolated Shield cavity, its feature are：The gap of splicing or connection therein is solved by metal welding procedure,
This just necessarily so that both of splicing or connection form the structure of " full seal type ", can utterly prevent gas molecule or
Fluid molecule is penetrated from the position of welding.
If some position of the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield in the present invention
It is that sealing is implemented by the fastening of bolt using the sealing material of dismountable nonmetallic rubber one kind, then, the isolation
Air molecule in shielding cavity still can penetrate away from above-mentioned flexible non-metallic sealing material, simply its transmission rate
May be slowly.--- for example：It is not that the bicycle tube produced by high molecular material is not inflated for a period of time with doughnut
It is capable, it is clear that this is because it is excessive and can not prevent gas molecule therefrom low rate to form the distance between molecule of the material
Ground passes through, and exactly this " passing through ", " fatal " is formd for the waterproof sealing structure of the prior art, i.e.,：Design
And be mounted with after waterproof sealing application specific architecture and its professional component, gas molecule is added on the contrary or fluid molecule can be slow
The passage that leaks passed through, that is, do not play the role of real waterproof sealing.
If the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield and metal in the present invention are close
Some position of seal structure 10 be implemented using the metal flat of dismountable two unusual lights by the fastening of bolt it is close
Envelope, then, at least the air in the Isolated Shield cavity still can be worn between the metal flat of above-mentioned two unusual lights
Saturating (all there are roughness for smooth any plane again --- and its smooth gap pressed can not prevent wearing for gas molecule
Thoroughly), be its transmission rate may slowly some.
The above two " if " example fully demonstrate why prior art immersible pump there is in " background technology "
Described " being difficult to " or under water cannot " throughout one's life " the problem of, and can not prevent outside the fluid molecule in liquid pump 9
The problem of letting out.--- this obviously at least due to：The removable seal structure used in the prior art in its key position
(such as：Polymeric seal element) reason that gas molecule or fluid molecule are penetrated from its sealing defence line can not be resisted.
So far, it should which very clear, the present invention is exactly reality because of the simple metal seal cavity at least employing key
Show oneself " full seal type ", and ensured with this：Where air molecule in simple metal seal cavity, be subject to extraneous water body
I guess under powerful water body pressure (immersible pump diving more deep-water pressure is bigger), and do not have：From its sealing of encirclement
Chance or possibility that the position (top) in addition to bottom of cavity is let out, this can not leak fluid body molecule
As a result, just also ensuring the high-pressure water body in the external world in turn will not exist：
It can be entered by 7 position of electric machine shaft gland that above-mentioned permission fluid molecule passes through in the simple metal seal cavity
Chance or possibility, be finally to ensure that：Rotor 2 can not possibly touch from the accumulation water body that penetrates of the external world and
Make motor corrupted, i.e.,：Form in submersible pump structure utilize " full seal type " simple metal seal cavity in gas, success and
The waterproof sealing principle being reliably carried out inside " air jacking " extraneous water body infiltration immersible pump.
It is not difficult to find out：In the present invention in above-mentioned " full seal type " simple metal seal cavity, only its bottom just allow with
Less area is for example contacted as the rubber (containing minimum gap) of soft high molecular material with extraneous water body, such as：
7 position of electric machine shaft gland, and inflation nozzle mechanism P (structure for being similar to the air inflation nozzle inflated for bicycle tube) are shown with pressure
Device interface K (structure for being similar to basketball air inflation nozzle), exactly (refers to showing for attached drawing positioned at the bottom of the seal cavity
Meaning).--- obviously, which is that can not prevent fluid point
What son therefrom passed through, and other positions in the seal cavity, i.e., the position in addition to bottom are cannot to set to allow to flow
Any element that body molecule can pass through or component.
In conclusion the present invention successfully starts with and overturns from the Principle Method (utilizing air jacking principle) of waterproof sealing
The overall structure of the prior art, and clearly illustrate：
It is highest latent in technical requirements with " the sealing ring solid element made of flexible high molecular material " in the prior art
In water pump structure, can not realize can prevent fluid molecule from passing through its waterproof sealing three-dimensional defense line.
Obviously, " air jacking " principle formed in structure of the present invention, is to reach utterly from prevention fluid
The effect of three-dimensional waterproof sealing is formd in the aspect of molecule " passing through ".--- realized so long as not from the aspect of fluid molecule
" absolute " two words, just inevitably exist allow immersible pump " periodically disembarkation safeguard water removal " restrictions immersible pump technology develop and give people
Manufactured the conventional program of very burden.
Since the present invention realizes " air jacking " principle, the mechanism of various sealing elements and its adapted is eliminated, latent
Will necessarily occur in the overall structure of water pump with looks that are brand-new and being simplified again.
The diving startup program of gas jacking pressure balance problem and immersible pump in the three, present invention：
There is the inflation being connected with the bottom of above-mentioned metal sealing Isolated Shield cavity by inflating connecting leg 12 in the present invention
Nozzle mechanism P, if necessary, can also increase the inflation pressure display device interface for being also and inflation connecting leg 12 is connected using auxiliary
K, the inflation nozzle mechanism P (gas is only accurate and then is not allowed) similar to the air inflation nozzle such as set on bicycle tube, the inflation
Pressure-display device interface K can also use the simplest pin type air inflation nozzle interface form as on basketball, and (gas both can be into having
It can go out)；Both of the setting are to aim at：Before the present invention, it is ensured that inside immersible pump, i.e., in metal sealing Isolated Shield cavity
Pressure be greater than or equal to immersible pump where the depth of water pressure.--- there is no above-mentioned inflation nozzle mechanism P and pressure in the prior art
Power display device interface K.
Generally can by rule of thumb using manually (such as：Utilize inflator degree as beating sufficient bicycle tube
Reach the degree for allowing immersible pump to dive under water about tens meters to hundred meters or so) or electric inflator (that for preferably thering is pressure to show)
Or chemistry anger reacts the technological means such as bag before diving uses immersible pump, to realize the supercharging inside for immersible pump, usually
Supercharging reaches the pressure more than or equal to the depth of water where immersible pump, such as：
10 meters of equivalent to one atmospheric pressures of diving, i.e.,：1 kg/centimetre2；
100 meters of equivalent to ten atmospheric pressures of diving, i.e.,：10 kgs/centimetre2；
Obviously, just need to measure the water-bed depth that the immersible pump needs to slip into, meter before the present invention is placed on the bottom
The pressure for needing to be pressurized is calculated, afterwards, supercharging program is implemented (on the bank) under the premise of anhydrous to the immersible pump, finally, you can
The immersible pump is sunk under water and is powered and starts underwater diving pump work.
Illustrate a bit：
When allowing, the diving depth of immersible pump is little, when carrying out being pressurized program to immersible pump on the bank, can utilize people by rule of thumb
Work inflator is pressurized, and not related if boost pressure is excessive, the pressure inside immersible pump can be in the period of one considerably long
The interior electric machine shaft gland 7 mainly passed through in the present invention, the gas leakage from its underpart outwardly water body, until it is consistent to reach external and internal pressure
Untill, it is clear that extraneous water body will not pass through electric machine shaft gland 7 and enter inside immersible pump.
When allowing, the diving depth of immersible pump is larger, when carrying out being pressurized program to immersible pump on the bank, such as using manually inflating
Cylinder supercharging when, preferably again by means of auxiliary the blowing pressure display equipment help, by pressure display unit (pressure gauge) i.e.
The pressure value inside immersible pump can be observed directly, this is favourable in being accurately finished the supercharging program；Especially it incite somebody to action this
Invention is used for when deep water uses with greater need for such.
The problem of during four, present invention work on internal liquid molecule could be leaked to the external world：
If 4 or wide type metal sealing Isolated Shield 5 (structure containing dragging motor) of narrow metal sealing Isolated Shield is
The upper position of liquid pump 9 is removeably positioned by several screws, operationally it is internal for liquid pump 9 at this time
Liquid is completely can be by dismountable position (screw positioning belongs to non-tight type), to the liquid inside extraneous leakage fluid pump 9
Body molecule.--- if the liquid of 9 internal flow of liquid pump is water, that is, allows the leakage of water, then, above-mentioned " dismountable side
Use of the structure of formula positioning " for the present invention, is influenced without what；If the liquid of 9 internal flow of liquid pump is valuable
Or extremely hazardous flowing material, then, for the use of the structure of above-mentioned " dismountable mode positions " for the present invention,
Just absolutely not allow.--- the present invention is exactly that the top level structure form for aiming at " absolutely not the allowing " takes denomination of invention
, if having made the present invention of the top level structure form, then, in structure manufacture will not it is complicated how much, however,
In terms of purposes, just very extensive, benefit is in disadvantage.
In summary：
In general, motor is a highly developed product, as long as ensuring that rotor 2 therein is in atmosphere all the time
Rotary work, then, motor will work efficiently and on the premise of being less likely to be damaged very much.Therefore, by the present invention
Rotor 2, which is arranged in 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield, does not just have to worry in length yet
Easily occur after period operation from the problem of damage.--- usually by the durable apparatus of motor drag, such as：Do washing mechanical, electrical
Refrigerator and sky wither device, etc., disposable maintenance-free adapted service life of its dragging motor and output component mostly 15 years with
On, and World Famous Brand then can reach more than 30 years.For this reason, employ non-removable welding in belonging to the present invention of simple products
Technique come implement it is a variety of linking (prevent product is from carrying out demolition and maintenance or maintenance), however, can't influence to be approved by people
The disposable service life of the invention time limit because in the time limit in the disposable service life of immersible pump of the present invention, be not to take
The certainly function of the waterproof seal in immersible pump complete machine, but depending in no waterproof seal complete machine dragging motor make
Use the service life.
