The sealing ring of lattice serves as) resist extraneous water body for the infiltration within immersible pump dragging motor.
During to this end, people use immersible pump operation, the general service intervals time will not oversize (at least a couple of months and at most
It is difficult to the shortest more than the service intervals time of 1 year the biggest then immersible pump of diving depth), as long as after Shi Yonging, it is necessary for periodically
It is left the water and to safeguard (not being corrupted maintenance) by ground, allows coming into the infiltration within motor for submerged pump and have an opportunity by artificially
Remove in time, cause whole motor corrupted to avoid rotor to touch growing number of infiltration.Compact submersible pump this
The most many times disembarkation of sample ground is safeguarded and still can be allowed except water, can medium-sized, even Large diving pump so regularly from bank waterborne
Safeguard except water, just have trouble, even have burden to such an extent as to be difficult to be normally used it, such as: several ten thousand or hundreds of thousands very
Medium-sized or the Large diving pump of supreme megawatt is just difficult to enter or not can enter the product operational phase of routine；Study carefully
Its reason is exactly: type is the biggest, dives under water the deepest, and " disembarkation is safeguarded except water " is just more difficult to, the most frequent.
Cause above-mentioned behaviour in service, the reason mainly causing the service intervals time not grow, it is simply that the diving of prior art
Pump waterproof sealing structure, i.e. crucial waterproof seal ring the most definitely cannot accomplish: stop air molecule or hydrone from
In the degree passed through, it may be assumed that extraneous hydrone passes through waterproof seal ring and gets in immersible pump, and by air original in immersible pump
Point passing through waterproof seal ring by force is extruded immersible pump, it is clear that: above-mentioned waterproof seal ring has functioned only as delaying air to divide
Son and hydrone pass through the time of oneself, thus are just difficult to:
Allow immersible pump use the most under water, be still placed under water after shutdown, use the most under water, once more
It is placed under water ..., until constituting the liquid pump of this immersible pump or dragging motor alternative one, (motor is easiest to bad by contrast
Damage) oneself cause corrupted to shut down after long-term work is worn and torn.That is: it is difficult to make immersible pump the most underwater
In environment " throughout one's life ".
Summary of the invention
The purpose of the present invention:
It is contemplated in the sealing part of immersible pump, overturns the high molecule sealing materials design that people use all the time

Pump puts on bank demolition and maintenance (not being maintenance) except the problem of water.
The purpose above-mentioned in order to realize the present invention, intends using following technical scheme:
The present invention includes: the dragging motor that the stator by rotor with embedding winding of conventional structure form is constituted passes through
The liquid pump that its rotating shaft drives；
It is characterized in that:
At least allow rotor by narrow metal sealing isolation surround with stereogenic, and, narrow metal sealing every
It is provided with electric machine shaft gland from the bottom of cover and is provided with charging connector mechanism；The charging connector mechanism connected by inflation connecting leg should
This is considered as including: this charging connector mechanism itself or add auxiliary be also and inflation connecting leg connect the blowing pressure display dress
Put interface, the former can on such as bicycle tube arrange charging connector similar, the latter can with basketball on arrange for pin type
The interface of airing form is similar (fill basketball, exit)；
All splicing gaps that described narrow metal sealing isolation relates to are all by non-removable welding procedure
Realize connection；
The bottom of described narrow metal sealing isolation is provided with in case the unexpected water occurred oozes tactile water alarm device.
Gap between this described rotor and this stator falls within by the part of narrow metal sealing isolation isolation,
And the isolated part of this local uses slim non-magnet material to serve as, and, this narrow metal sealing isolation local is fixed with this
The internal ring circumferential location of son is in tight fit state.
Described narrow metal sealing isolation carries out having gap to position by dismountable screw fastener and liquid pump；
Or:
Described narrow metal sealing isolation is to realize carrying out gapless with liquid pump by non-removable welding procedure
Location.
The using method of the present invention, the preparation before i.e. using is as follows:
Must be by charging connector mechanism to immersible pump inner inflatable, its blowing pressure is more than or equal to immersible pump water to be slipped into
Deep water pressure, afterwards, it becomes possible to immersible pump is put under water and be energized allow it start work.
The feature of the present invention:
One. owing to the present invention structurally can by the charging connector mechanism of setting to immersible pump inner inflatable (such as: adopt
With simplest manual pump plenum), to guarantee that the immersible pump worked in certain diving depth can be with gas
The mode of jacking resists the infiltration of the extraneous water body with certain pressure, this just for meet first waterproof sealing of immersible pump will
Ask, be and achieve immersible pump internal pressure utterly and create condition more than or equal to extraneous water body pressure.Existing skill
The critical defect of art is: immersible pump internal pressure less than or well below on the premise of extraneous water body pressure, the most only
Rely on the strength of macromolecule flexible water potted component that fluid molecule can penetrate and invalid resisting is carried out in a short time
Temporarily sealing.
Two. the most at least rotor is defined due to the present invention and fluid molecule can be stoped to pass through in aspect
" full seal type " and the simple metal seal isolation shielding cavity existed with solid encirclement form, machine shaft therein is from this shielding
Cavity bottom passes through the axle envelope position of routine to liquid pump outputting rotary power, and this is just for meeting second waterproof sealing of immersible pump
Requirement, be ensure that in this shielding cavity utterly air molecule cannot bottom it beyond any position have an opportunity or
Likely leakage creates condition.The critical defect of prior art is: there is the above-mentioned air amount with molecule utterly
The problem leaked to external world of level, although its speed is the slowest.
Three. owing to the mechanism of air jacking water body of the present invention can become in the waterproof sealing structure of immersible pump
Vertical, this just can leak into immersible pump in dry place by disembarkation demolition and maintenance solution water not needing for the present invention
On the premise of inside, and allow immersible pump be constantly in underwater environment also to be able to realize the problem of above-mentioned " throughout one's life " and create
Condition.And then for realizing manufacturing high-power or super high power immersible pump (such as: myriawatt or the diving of tens myriawatts in manufacture
The conventional maintenance of infiltration is mainly cleared up in pump but need not dismounting of periodically debarking) create condition.
Four. due to the potted component entity not used in the present invention in prior art on conventional meaning and the knot of adapted thereof
Structure, will cause diving pump structure to simplify generally, but, its waterproof sealing performance has surmounted the most far away prior art, reaches
Having arrived the degree of positive confinement, this regeneration product that just at least can become prior art immersible pump for the present invention creates bar
Part.The critical defect of prior art is: potted component entity and structure thereof that it is set cannot limit gas molecule
Or the penetrating of fluid molecule, the purpose slowed down only up to transmission rate, therefore, prior art immersible pump periodically debarks dismounting dimension
It is inevitable for protecting (not being that infiltration task is mainly removed in maintenance) work.

Detailed description of the invention
Core overview of the present invention: in order to avoid rotor 2 connects with penetrating into the extraneous water body taken care of the pence inside immersible pump
Touch and finally damaged motor, at least rotor is defined the three-dimensional metal sealing Isolated Shield cavity surrounding character,
And, the only rotating shaft 6 of this rotor 2, by axle envelope position 7, liquid pump 9 is exported revolving force, it is clear that if extraneous water body
It is intended to enter the cavity (inner chamber) of this metal sealing Isolated Shield formation and contact with rotor 2, the most only along rotating shaft 6 the most upwards
Pass through axle envelope position 7 can enter, but, as long as the air pressure in this Isolated Shield cavity is sufficiently large, it is to be fully able to
Jacking firmly (prevention) extraneous water body passes through minimum axle envelope position 7, above-mentioned gap and enters in this Isolated Shield cavity from top to bottom
's.
Explain the main points briefly and the signal of accompanying drawing according to above, it should be substantially appreciated that the mechanism of the present invention, with
Under related keyword particular problem when again the technology of the present invention being implemented remake explanation further below:
One. the formation problems of the narrow metal sealing Isolated Shield 4 of the present invention:
In narrow metal sealing Isolated Shield 4, it is provided with by slim (example between its motor stator 1 and rotor 2
Such as desirable 0.1 millimeter of its thickness) composition this narrow metal of making of non-magnet material (have drawn from rustless steel or pyrite, etc.)
The Part portions of seal isolation shielding 4 entirety；And other positions of this narrow metal sealing Isolated Shield 4 can use abundant
Material is produced, and (the general thickness in little medium-sized immersible pump can use 2 millis can to take the magnitude that its thickness is several millimeters
Rice)；And the gap constituted between this narrow metal sealing Isolated Shield 4 different parts must use welding procedure to realize, and
And should forbid to occur the phenomenon (avoid rosin joint or dry joint the most ripe) of rosin joint or dry joint, this narrow isolated screen
The way that the final molding covering 4 can use local to implement the last assembly of integral solder after installing again realizes.Purpose
Be: allow this narrow metal sealing Isolated Shield 4 after assembly formed one except electric machine shaft gland position 7, its underpart (permissible
Use conventional shaft seal structure but the infiltration of water body cannot be stoped) beyond monolithic devices close by gas molecule or fluid molecule
The metallic cavity that all cannot penetrate, only this metallic cavity, i.e. constitute this narrow metal sealing Isolated Shield 4 metallic molecule it
Between gap, be less than the diameter of general gas flow molecule or fluid molecule.
Owing to motor stator 1 is isolated by narrow metal sealing Isolated Shield 4 with both rotors 2 so that relative to appearance
The motor stator 1 of flimsy cincture winding becomes detachable, but can suitably increase some difficulty on manufacturing.
Two. the present invention relates to " full seal type " problem of metal sealing Isolated Shield cavity:
The structure problem of metal sealing Isolated Shield cavity is have employed owing to narrow metal sealing Isolated Shield 4 belongs to, its
Feature is: the gap of splicing therein or connection is solved by metal solder technique, and this most necessarily makes splicing or connects
Define the structure of " full seal type " both connecing, gas molecule or fluid molecule i.e. can be stoped to wear from the position of welding
Thoroughly.
If certain position of the narrow metal sealing Isolated Shield 4 in the present invention is to use dismountable nonmetal rubber
The encapsulant of skin one class implements sealing by the fastening of bolt, then, the air molecule in this Isolated Shield cavity is still
So can penetrate away from above-mentioned flexible non-metallic encapsulant, simply its transmission rate may be slowly.Such as:
It is not all right that the bicycle tube produced by macromolecular material and air tube a period of time do not inflate, it is clear that this is due to structure
Become the distance between the molecule of this material excessive and pass through while gas molecule therefrom low rate cannot be stoped, and the most this " wear
More ", for the waterproof sealing structure of prior art, " fatal " key element is defined.
If, certain position of the narrow metal sealing Isolated Shield 4 in the present invention be use dismountable two very
Smooth metal flat is implemented to seal by the fastening of bolt, then, the air in this Isolated Shield cavity still can be from
Penetrate between the metal flat of above-mentioned two unusual light (all there is its of roughness and press in the most smooth any plane
Smooth gap cannot stop penetrating of gas molecule), simply its transmission rate may slowly some.
Above two " if " example fully demonstrate why prior art immersible pump also exists in " background technology "
Described " being difficult to " or under water can not the problem of " throughout one's life ".This be due to: in prior art crucial at it
Position use removable seal structure (such as: polymeric seal element) cannot resist gas molecule or fluid molecule from
It seals the reason penetrated in defence line.
So far, it should the clearest, the present invention is just because have employed the simple metal sealing cavity of key and achieving
" full seal type " of oneself, and guaranteeing with this: the air molecule in simple metal annular seal space body, by extraneous water body even
Under powerful water body pressure (immersible pump dive under water more deep-water pressure the biggest), also it is not have: from surrounding its this sealing cavity
The chance that lets out of the position (top) in addition to bottom or probability, this cannot the knot of leak fluid body molecule
Really, the most just in turn ensure that the high-pressure water body in the external world does not exists: can be by the above-mentioned motor shaft with minimal clearance
Seal 7 positions and enter the chance in this simple metal annular seal space body or probability, be finally to ensure that: rotor 2 is impossible
Touch the accumulation water body penetrated from the external world and make motor corrupted, it may be assumed that define utilization in submersible pump structure " hermetically sealed
Type " gas in simple metal annular seal space body, success and be reliably carried out inside " air jacking " extraneous water body infiltration immersible pump
Waterproof sealing principle.
It is not difficult to find out: " full seal type " simple metal above-mentioned in the present invention seals in cavity, only allows bottom it with relatively
Little sectional area (gap) contacts, such as with extraneous water body: have electric machine shaft gland 7 position and the charging connector of minimal clearance
Mechanism P is just in the bottom of this sealing cavity.The rwo all cannot stop fluid molecule therefrom to pass through.And
Other positions in this sealing cavity, i.e. position in addition to bottom cannot arrange permission fluid molecule and can pass through
Other elements or parts.
In sum, the present invention has successfully overturned prior art, i.e. overturns:
Prior art cannot require the highest in technology with " the sealing ring solid element being made up of flexible high molecular material "
Immersible pump in realize the skill of above-mentioned above-mentioned " full seal type " waterproof sealing three-dimensional defense line that fluid molecule can be stoped to pass through
Art.
Obviously, " air jacking " principle formed in present configuration, it is simply that can reach utterly from stoping fluid
The effect of three-dimensional waterproof sealing is defined in the aspect that molecule " passes through ".Realize so long as not in the aspect of fluid molecule
" definitely " two words, just unavoidable exist allow immersible pump " periodically disembarkation is safeguarded except water " restriction immersible pump technology development and to people
Manufactured the conventional program of very burden.
Owing to present invention achieves " air jacking " principle, eliminate the mechanism of various potted component and adapted thereof, latent
Will necessarily occur with looks that are brand-new and that be simplified again in the overall structure of water pump.
Three. the gas jacking pressure balance problem in the present invention and the diving startup program of immersible pump:
The present invention exists the inflation that the bottom with above-mentioned metal sealing Isolated Shield cavity is connected by inflation connecting leg 12
Nozzle mechanism P, if desired, it is also possible to increase and utilize assist be also and inflate the inflation pressure display device interface that connecting leg 12 is connected
K, this charging connector mechanism P are similar to the charging connector interface arranged on such as bicycle tube, this inflation pressure display device interface K
Can also use simplest such as the pin type charging connector interface shape on basketball；Both this settings are to aim at: use the present invention
Before, it is ensured that inside immersible pump, i.e. the pressure in metal sealing Isolated Shield cavity is more than or equal to the pressure of the immersible pump place depth of water
Power.Prior art does not exist said mechanism P and interface K.
Typically can use by rule of thumb manually (such as: utilize inflator degree as beaten foot bicycle tube
Reach to allow immersible pump dive under water the degree of about tens meters to about hundred meters) or electric inflator (preferably have pressure show that)
Or the angry technological means such as bag of reacting of chemistry are before diving uses immersible pump, realize for the supercharging within immersible pump, generally
Supercharging reaches the pressure more than or equal to the immersible pump place depth of water, such as:
Dive under water 10 meters and be equivalent to an atmospheric pressure, it may be assumed that 1 kgf/centimetre2；
Dive under water 100 meters and be equivalent to ten atmospheric pressures, it may be assumed that 10 kgfs/centimetre2；
Obviously, it was accomplished by measuring the water-bed degree of depth that this immersible pump needs to slip into, meter before the present invention is placed on the bottom
Calculate the pressure needing supercharging, afterwards, this immersible pump is implemented supercharging program on the premise of anhydrous (on the bank), finally,
Sink under water this immersible pump and be energized the immersible pump work started under water.
Illustrate a bit:
When making the diving depth of immersible pump little, when immersible pump is carried out supercharging program on the bank, people can be utilized by rule of thumb
Work inflator supercharging, if boost pressure is too high, it doesn't matter, and the pressure within immersible pump can be a considerably long period
Interior by the electric machine shaft gland 7 in the present invention, leak gas from its underpart outwardly water body, until it reaches till external and internal pressure is consistent,
Obviously, extraneous water body will not pass through electric machine shaft gland 7 and enters inside immersible pump.
So far, be not difficult to find out, be arranged on metal sealing Isolated Shield cavity bottom electric machine shaft gland 7 and rotating shaft 6 it
Between be operationally in absolute dynamic mated condition (the tight fit state even in static), be absolutely not to stop stream
Body molecule passes through, and, which pressure is low, and which head fluid molecule will flow to.
When making the diving depth of immersible pump relatively big, when immersible pump is carried out supercharging program on the bank, such as, utilize and manually inflate
During cylinder supercharging, preferably relend the help of the blowing pressure display equipment helping auxiliary, by pressure display unit (Pressure gauge) i.e.
Can observe directly the pressure value within immersible pump, this is favourable in being accurately finished this supercharging program；Especially incite somebody to action this
Invention is used for when deep water uses with greater need for so.
Four. about the problem that could leak internal liquid molecule to external world when the present invention works:
If narrow metal sealing Isolated Shield 4 (all containing dragging motor structure) is with removable by several screws 10
The mode unloaded is positioned at the upper position of liquid pump 9, and operationally its internal liquid of liquid pump 9 now is completely can be by can
The position (being positioned caused by screw 10) of dismounting, to external world leakage fluid molecule within liquid pump 9.If liquid pump 9 is internal
The liquid of flowing is water, i.e. allows the leakage of water, then, the structure of above-mentioned " dismountable mode positions " is for the present invention's
Use, do not have anything to affect；If the liquid of liquid pump 9 internal flow is valuable or extremely hazardous flowing material, then,
The structure of above-mentioned " dismountable mode positions ", for the use of the present invention, is the most unallowed.
If narrow metal sealing Isolated Shield 4 (all containing dragging motor structure) is by non-removable metal solder
Mode is positioned at the upper position of liquid pump 9, the i.e. gap of two parts and is all realized by welding procedure, and liquid pump 9 now exists
During operation, its internal fluid molecule is impossible to have leaked to external world.This is expensive for the liquid of liquid pump 9 internal flow
For weight or extremely hazardous flowing material, non-key position is also adopted by " full seal type " realized by welding procedure
Structure is the most necessary；Otherwise (such as pump is water), just need not.
In sum:
In general, motor is a highly developed product, as long as guaranteeing that rotor 2 therein is in atmosphere all the time
Rotary work, then, motor is not easy to damage the most very much.Therefore, the rotor 2 in the present invention is arranged on narrow metal
The most just do not worry in seal isolation shielding 4 being susceptible to from the problem damaged after running over a long time.General by
The durable apparatus of motor drag, such as: washing machine, electric refrigerator and sky wither device, etc., its dragging motor with exert oneself parts once
The property maintenance-free adapted life-span, World Famous Brand then can reach more than 30 years mostly more than 15 years.To this end, belong to simple product
The present invention of product have employed non-removable welding procedure to implement multiple linking (making product can not carry out demolition and maintenance),
Do not interfere with the time limit in the single use life-span of the present invention approved by people.
