Abstract
The invention relates to an application method and a structure of a pump including an immersion pump supported by air jacking seal. The application method comprises: I, the general situation of the pump: a rotor (2) of a motor is at least surrounded by narrow metal seal isolation (4) or a wide metal seal isolation (5) in a three-dimensional way, and a charging connector mechanism (P) is at least arranged on the bottom part of the seal isolation; II, the preparation work before application: the inner part of a liquid pump is charged through the charging connector mechanism (P), and when the charging pressure is larger than the pressure of the immersion depth of the pump, the pump can be placed under a liquid level and powered on for working, and the pump can also be placed above the liquid level for working; liquid molecules in the pump cannot be leaked when the pump is running; and all splicing gaps related to the outer surface of the pump are connected through a detachable welding process. The continuous cumulative time of one-time working and idling of the pump underwater depends on the service life (about more than 30 years) of the motor, and the diving depth of the pump is infinite, so that a condition is created for the pump to become an update product of an immersible pump, and the structure of the pump is probably more suitable for a common water pump.
Description
Technical field
The present invention relates to by the inclusion immersion pump of air jacking sealing support, (submersible depth is dived with disposably continuable
The water time all reaches infinitely) in the using method of interior pump (molecule of liquid in the pump that will not leak) and its structure.
Background technology
At present, all size immersible pump different from model emerges in an endless stream, be purposes quite extensively and one kind of maturation is moved
Power equipment, its deficiency is：Immersible pump relies primarily on its sealing structure (various rule being made up of macromolecule flexible material under water
The sealing ring of lattice is serving as) resisting extraneous water body for the infiltration within immersible pump dragging motor.
For this reason, when people use immersible pump operation, general service intervals time will not oversize (at least a couple of months and at most
It is difficult to shorter more than the service intervals time of the more big then immersible pump of 1 year diving depth), as long as after using, it is necessary for periodically
It is left the water and safeguards (not being corrupted maintenance) by ground, allows the infiltration coming within motor for submerged pump to 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
Many times disembarkation safeguards that eliminating water still can allow repeatedly on sample ground, can medium-sized, even Large diving pump so regularly from bank waterborne
Safeguard eliminating water, just have 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 not can enter the product operational phase of routine；Study carefully
Its reason is exactly to be：Type is bigger, and diving is deeper, and " eliminating water is safeguarded in disembarkation " is just more difficult to, more frequent.
The reason cause above-mentioned behaviour in service, mainly cause the service intervals time long is it is simply that the diving of prior art
Pump waterproof sealing structure, that is, crucial waterproof seal ring definitely cannot accomplish in design：Stop air molecule or hydrone from
In the degree passed through, that is,：Extraneous hydrone passes through waterproof seal ring and gets in immersible pump, and by air original in immersible pump
Point pass through by force again waterproof seal ring be 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 to use under water always, be still placed under water after shutdown, use under water again afterwards, once more
Be placed under water ... ..., until constitute the liquid pump of this immersible pump or dragging motor alternative one (by contrast motor be easiest to bad
Damage) oneself cause corrupted to shut down after long-term work abrasion.I.e.：It is difficult to make immersible pump underwater always
In environment " throughout one's life ".
Furthermore, not yet can ask at present directly for a long time in tens meters of immersion pumps even working in hundreds of meter of depth underwater
Generation.Because the prior art waterproof sealing structure of above-mentioned requirements to be reached not yet comes out.
Additionally, any liquid pump, such as water pump, it is all to allow water pump outwardly to leak its internal water, but does not allow to surpass
Mark, otherwise, there is the quality problems of water pump.Prior art let alone allow water pump operationally not allow to external world
Leak the problem of its internal hydrone.
Content of the invention
The purpose of the present invention：
Be exactly overturn from structure first immersible pump existing waterproof sealing link start with (using air jacking seal former
Reason), and solve the problems, such as simultaneously and in passing will not externally in leakage pump body water (liquid) molecule structure treatment.
The purpose above-mentioned in order to realize the present invention, intending can be using following technical scheme：
The using method of the present invention：
First, the structure in general of pump：
At least allow the rotor of motor be isolated by narrow metal sealing or surrounded with stereogenic by the isolation of wide type metal sealing
, and, in the bottom of this seal isolation at least provided with electric machine shaft gland and inflation nozzle mechanism, and, in the week constituting liquid pump
Enclose and bottom is to be surrounded with stereogenic by shape metallic leak-proof structure；
2nd, pump preparation before use：
One of method：If being intended to be placed on below liquid level position to use pump, first passing through inflation nozzle mechanism and liquid pump inside is filled
Gas, then the pressure gauge observation connected by pressure-display device interface, or otherwise feel (for example：Using beating manually
During cartridge inflation), it becomes possible to this pump being put into below liquid level and leading to after the depth pressure that the blowing pressure to be slipped into more than pump
Electricity allows it start work, and now, this pump will not flow through the fluid molecule within this pump to pump external leakage；
The two of method：If being intended to be placed on the above position of liquid level to use pump, after allowing pump energising start work, this pump is equally not yet
Pump external leakage can be flow through with the fluid molecule within this pump；
Described isolated by narrow metal sealing or metal sealing isolated chambers that wide type metal sealing isolation is formed respectively,
It is to realize being connected by the welding procedure at non-removable welding circle position between shape metallic leak-proof structure；
It is all that described narrow metal sealing isolation or wide type metal sealing isolation and shape metallic leak-proof structure are related to
Splicing gap is all to realize by non-removable welding procedure connecting.
Meet the structure of the pump of using method of the present invention：
Including：The rotating shaft by it for the dragging motor being made up of the stator that rotor embeds winding of conventional structure form
The liquid pump driving；
And：
3rd, rotor is at least allowed to be surrounded with stereogenic by the isolation of narrow metal sealing in structure, or, at least allow
Rotor is surrounded with stereogenic by the isolation of wide type metal sealing with stator, and, in narrow metal sealing isolation or wide
The bottom of type metal sealing isolation is provided with electric machine shaft gland and can charging connector machine including pressure-display device interface
Structure；
4th, in structure constitute liquid pump around and bottom be with stereogenic by non-removable shape metallic leak-proof structure
Surround, and, feed liquor interface tube and discharge opeing interface tube are provided with liquid pump.
The described rotor that allows is isolated with the cingens part of stereogenic using slim non-magnetic material by narrow metal sealing
Expect to serve as, and, this narrow metal sealing isolation local is in dismountable tight fit with the internal ring circumferential location of this stator
State.
The feature () of the present invention taking immersible pump as a example：
One. because the present invention in structure can by the inflation nozzle mechanism of setting to immersible pump inner inflatable (for example：Adopt
With simplest manual pump plenum), ensure that the immersible pump working in the diving depth of sets itself can
The extraneous water with certain ambient pressure or very big ambient pressure is resisted in the way of the internal gas jacking of required pressure
The infiltration of body, as utterly achieves immersible pump internal pressure and is more than (or being equal to) external world water body for infiltration pressure inside whole machine
Power and the gas jacking pressure value that sets creates condition.And then having established the present invention, can be applied to any diving deep
The immersible pump of degree work creates condition.
The critical defect of prior art is：The internal pressure of an atmospheric pressure can only be adopted (to tie up in immersible pump
Hold ambient pressure when this immersible pump manufactures) come to resist extraneous more than or much larger than an atmospheric pressure extraneous water body for diving
On the premise of the internal seepage pressure of water pump, that is, rely solely on the macromolecule flexible water sealing unit that fluid molecule can penetrate
The strength of part and invalid resist the temporarily sealing to carry out in a short time, cause：Prior art must often (regular) disembarkation
Safeguard (main task be cleaning eliminate infiltration), and, diving depth is bigger, and periodically debark cycle of maintenance of immersible pump gets over
Short that is to say, that can not allow immersible pump be constantly in underwater environment realize " throughout one's life " purpose；In order to regular
Hang the water surface and safeguard, prior art is merely able to be suitable for manufacturing be operated in and leave the close small pump of the water surface.
Two. due to the metal isolated by narrow metal sealing in present configuration or wide type metal sealing isolation is formed respectively
Seal isolation cavity, is to realize being connected by the welding procedure at non-removable welding circle position between shape metallic leak-proof structure
, the fluid molecule that this is just capable of within the operationally approach present invention for the present invention will not leak and create bar
Part.In engineering, if some valuable liquid of pumping or during extremely toxic liquid under water, the height that this kind of engineering has
Require it is likely to the necessary of it or prerequisite can be adopted.
The critical defect of prior art is：During normal work, definitely do not accomplish this point, the Standard of water pump
(including all of country) is typically all " permission leaks but can not be exceeded ".
Three. due to constituting in " full seal type " complete machine structure form that special liquid pump in invention is with actuating unit, only
Be provided with one be located at metal sealing isolated chambers bottom and fluid molecule can be allowed can to pass through electric machine shaft gland (only this
" one " is unavoidable in structure), however, not any other in complete machine structure can convey this fluid molecule
The gas molecule of same volume can also leave this seal isolation chamber under penetrating into liquid extruding, and what that is, gas molecule leaked leads to
Road or gap, this just be the present invention in the case of gas jacking from top to bottom in " full seal type " metal sealing isolated chambers,
So that more than the extraneous highly pressurised liquid of specific gravity of gas, being definitely somebody's turn to do of the present invention cannot be entered by passing through electric machine shaft gland from bottom to top
Seal isolation intracavity creates condition.
The critical defect of prior art is：Extraneous high-pressure water body can be by the minimum above-mentioned electric machine shaft gland in position
The gas applying pressure in pump, and allow in this pump by the external world seep water extruded gas pass through at a slow speed the many places on electric machine shaft gland top by
The sealing that the potted component that the flexible macromolecule class encapsulant being embedded in dedicated optical coulisse gap structure is made is formed is three-dimensional
Defence line (cannot stop that gas molecule passes through sealing coil element and passes through to external leakage to the outside of whole machine), when the extraneous water penetrating into
Body, after accumulating and progressively replacing the originally occupied space of the gas being extruded, will finally be contacted simultaneously with rotor
Cause its corrupted.
Four. due to not adopting the knot of potted component entity on conventional meaning in prior art and its adapted in the present invention
Structure, to seal only with the gas jacking principle not needing potted component entity, population structure will cause existing
Immersible pump is integrally-built to be changed or simplifies, however, its sealing performance has but much surmounted prior art (having reached definitely
The degree of sealing), for this reason, " cost performance " of the present invention will necessarily be much larger than prior art, this just at least can become for the present invention
Regeneration product for prior art immersible pump creates condition.Meanwhile, it is suitable for most common water pump structure.
The critical defect of prior art is：Due to its set potted component entity and its adapted structure no
Method stops penetrating of gas molecule or fluid molecule, the purpose slowing down only up to transmission rate, and internally seep water reduced rate
Some, therefore, on complete machine structure, the final destiny waiting it is likely that exactly can allow existing immersible pump structure by this
Bright superseded.
Five. because the present invention can slip into required any depth position under water in engineering, and it continues under water
Time (contain：The time of time and the inoperative of work) can reach and infinitely great (need not periodically debark during this period and be excluded
The maintenance of infiltration), so, immersible pump of the present invention just can as needed or manufacturing capacity makes required extra heavy machine
Type is (for example：Make up to a million kilowatts of power prior art not on your life), it is efficiently direct pump under the rock stratum of deep-sea
Take away the submarine oil adopted, or, (not yet solve to enter at present for efficiently exploiting abundant " combustible ice " on the earth under water
Enter the method exploited on a large scale and be used for commercial object of practical stage) all create condition.The one of immersible pump of the present invention
Service life can depend on the service life of dragging motor (if World Famous Brand motor can reach 30 years to secondary property completely under water
Produce its life-span using best material to can reach close to 50 years or longer).
The critical defect of prior art is：The ring structure produced due to employing soft macromolecular material comes
Waterproof sealing, cannot prevent extraneous water body on the contrary and penetrate into existing immersible pump inside and cause the damage of motor, in immersible pump diving
Deeper, then under the premise of the shorter weak tendency performance of the maintenance period of periodically disembarkation exclusion infiltration, if making extra heavy diving
Pump is difficult to often debark and carries out periodic maintenance to exclude infiltration.

Specific embodiment
Taking immersible pump as a example, core overview of the present invention：In order to avoid rotor 2 takes care of the pence inside immersible pump with penetrating into
The contact of extraneous water body and finally damaged motor, at least rotor 2 is defined with the three-dimensional metal sealing surrounding property
Isolated Shield cavity, and, the only rotating shaft 6 of this rotor 2, by axle envelope position 7 to liquid pump 9 export revolving force it is clear that
If extraneous water body is intended to enter the cavity (inner chamber) of this metal sealing Isolated Shield formation and contact with rotor 2, only have
Pass through axle envelope position 7 upwards along rotating shaft 6 can enter, as long as however, the air pressure in this Isolated Shield cavity is enough
Greatly, it is to be fully able to from top to bottom jacking to live, stop：
It is minimum and along with by macromolecule flexible material potted component institute that extraneous water body from bottom to top passes through above-mentioned gap
Composition axle envelope position 7 and enter in this Isolated Shield cavity.
According to above explain the main points briefly and accompanying drawing signal it should substantially be appreciated that the mechanism of the present invention, with
Under involved related keyword particular problem implemented for the technology of the present invention remake explanation further below：
One. the formation problems of the narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 of the present invention：?
In narrow metal sealing Isolated Shield 4, be provided between its motor stator 1 and rotor 2 by slim (for example：Its thickness can
Take 0.1 millimeter) this narrow metal sealing Isolated Shield of composition of making of non-magnet material (have drawn from rustless steel or pyrite, etc.)
The Part portions of 4 entirety；And other positions of this narrow metal sealing Isolated Shield 4 can be produced using abundant material,
The magnitude (thickness in general little medium-sized immersible pump can adopt 2 millimeters) that its thickness is several millimeters can be taken；And constitute and be somebody's turn to do
Gap between narrow metal sealing Isolated Shield 4 different parts must be realized using welding procedure, and should forbid
The phenomenon (avoid rosin joint or dry joint technically very ripe) of existing rosin joint or dry joint, the final one-tenth of this narrow Isolated Shield 4
Type can be realized using the method that implement the last assembly of integral solder after the installation of local again.Purpose is：Allow assembly
This narrow metal sealing Isolated Shield 4 afterwards forms one (can be using conventional axle except its underpart electric machine shaft gland position 7
Seal structure but the infiltration of water body cannot be stoped) beyond monolithic devices all cannot penetrate by gas molecule or fluid molecule are close
Metallic cavity, only this metallic cavity, that is, constitute the gap between the metallic molecule of this narrow metal sealing Isolated Shield 4, be
Diameter less than general gas flow molecule or fluid molecule.
Because motor stator 1 and both rotors 2 are isolated so that with respect to appearance by narrow metal sealing Isolated Shield 4
The motor stator 1 of flimsy cincture winding becomes detachable, but it is difficult suitably to increase some on manufacturing
Degree.By contrast, motor stator 1 and motor stator 1 are both enclosed in it by wide type metal sealing Isolated Shield 5
In, it be manufactured much more simply, but so that with respect to its motor stator 1 being easily damaged become non-dismountable more
Change, concrete details are omitted it is clear that describing in detail.
Two. it is related to " full seal type " problem of metal sealing Isolated Shield cavity in the present invention：
Because narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 belongs to employ metal sealing
The structure of Isolated Shield cavity, its feature is：Splicing therein or the gap connecting are solved by metal welding procedure,
This just necessarily make splicing or connect both define the structure of " full seal type ", can utterly stop gas molecule or
Fluid molecule penetrates from the position of welding.
If, certain position of the narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 in the present invention
It is to implement by the fastening of bolt to seal using the encapsulant of dismountable nonmetallic rubber one class, then, this isolation
Air molecule in shielding cavity still can penetrate away from above-mentioned flexible non-metallic encapsulant, is its transmission rate
May be slowly.For example：It is not that the bicycle tube produced by macromolecular material and doughnut are not inflated for a period of time
Row it is clear that this is excessive and cannot stop gas molecule therefrom low rate due to constituting the distance between molecule of this material
Pass through, and exactly this " passing through ", define " fatal " for the waterproof sealing structure of prior art, that is,：Design
And after being mounted with waterproof sealing application specific architecture and its professional component, increased gas molecule on the contrary or fluid molecule can be slow
The passage that leaks passing through, that is, the effect not playing real waterproof sealing.
If the narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 in the present invention and metal are close
Certain position of seal structure 10 be implemented by the fastening of bolt using the metal flat of dismountable two unusual light close
Envelope, then, the air being at least in this Isolated Shield cavity still can be worn between the metal flat of above-mentioned two unusual light
It is saturating that (all there is its smooth gap pressed of roughness and cannot stop wearing of gas molecule in smooth any plane again
Thoroughly), be its transmission rate may slowly some.
Above two " if " example fully demonstrate why prior art immersible pump exists in " background technology "
Described " being difficult to " or under water can not " throughout one's life " problem, and cannot stop outside the fluid molecule in liquid pump 9
The problem let out.This obviously at least due to：The removable seal structure adopting in its key position in prior art
(for example：Polymeric seal element) reason that gas molecule or fluid molecule penetrate from its sealing defence line cannot be resisted.
So far it should very clear, the present invention is just because at least employing the simple metal seal cavity of key and reality
Show " full seal type " of oneself, and to have been guaranteed with this：Air molecule in simple metal seal cavity, by extraneous water body which
I guess, under powerful water body pressure (immersible pump diving more deep-water pressure is bigger), it is also not have：From its this sealing of encirclement
The chance or probability that let out in the position (top) in addition to bottom of cavity, this cannot leak fluid body molecule
As a result, just in turn ensure that extraneous high-pressure water body is also not in turn：
Can be entered in this simple metal seal cavity by above-mentioned electric machine shaft gland 7 position allowing fluid molecule to pass through
Chance or probability, be finally to ensure that：Rotor 2 can not possibly touch the accumulation water body penetrating from the external world and
Make motor corrupted, that is,：Define using the gas in " full seal type " simple metal seal cavity in submersible pump structure, success and
It has been reliably carried out " air jacking " external world water body and permeated the waterproof sealing principle within immersible pump.
It is not difficult to find out：In above-mentioned " full seal type " simple metal seal cavity in the present invention, only its bottom just allow with
The rubber (containing minimum gap) for example as soft macromolecular material for the less area is contacted with extraneous water body, for example：
Electric machine shaft gland 7 position, and inflation nozzle mechanism P (similar to the structure of the charging connector inflated for bicycle tube) shown with pressure
Device interface K (similar to the structure of basketball charging connector) is it is simply that showing of accompanying drawing (is referred in the bottom being located at this seal cavity
Meaning).Obviously, this aforesaid three (electric machine shaft gland 7, inflation nozzle mechanism P and device interface K) is all to stop fluid from dividing
Son therefrom passes through, and other positions in this seal cavity, that is, the position in addition to bottom is to arrange permission stream
Any element that body molecule can pass through or part.
In sum, the present invention successfully starts with and overturns from the Principle Method of waterproof sealing (using air jacking principle)
The overall structure of prior art, and clearly illustrate：
Dived in technical requirements highest with " the sealing ring solid element being made up of flexible high molecular material " in prior art
In water pump structure, cannot realize stoping fluid molecule from passing through its waterproof sealing three-dimensional defense line.
Obviously, " air jacking " principle formed in present configuration is it is simply that can reach utterly from prevention fluid
The effect of three-dimensional waterproof sealing is defined on the aspect of molecule " passing through ".Realize so long as not in the aspect of fluid molecule
" absolute " two words, just exist unavoidably and allow that the restriction immersible pump technology of immersible pump " periodically eliminating water is safeguarded in disembarkation " develops and give people
Manufactured the conventional program of very burden.
Due to present invention achieves " air jacking " principle, eliminating the mechanism of various potted components and its adapted, latent
Will necessarily be occurred with looks that are brand-new and being 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：
Exist in the present invention and pass through to inflate the inflation that connecting leg 12 is connected with the bottom of above-mentioned metal sealing Isolated Shield cavity
Nozzle mechanism P, if necessary, can also increase using auxiliary is also the inflation pressure display device interface connected with inflation connecting leg 12
K, this inflation nozzle mechanism P similar to the charging connector of setting on such as bicycle tube (gas is only accurate and then is forbidden), this inflation
Pressure-display device interface K can also (gas both can enter to have using the pin type charging connector interface shape on simplest such as basketball
Can go out)；Both this settings are to aim at：Using before the present invention it is ensured that inside immersible pump, that is, in metal sealing Isolated Shield cavity
Pressure be more than or equal to the immersible pump place depth of water pressure.There is not above-mentioned inflation nozzle mechanism P and pressure in prior art
Power display device interface K.
Typically can adopt manually (for example by rule of thumb：Using inflator as beaten sufficient bicycle tube degree
Reach the degree allowing immersible pump dive under water about tens meters to hundred meters about) or electric inflator (that preferably having pressure to show)
Or the technological means such as chemistry angry reaction bag are before diving is using immersible pump, to realize for the supercharging within immersible pump, generally
Supercharging reaches the pressure more than or equal to the immersible pump place depth of water, for example：
10 meters of diving is equivalent to an atmospheric pressure, that is,：1 kgf/centimetre2；
100 meters of diving is equivalent to ten atmospheric pressures, that is,：10 kgfs/centimetre2；
Obviously, it was accomplished by measuring the water-bed depth that this immersible pump needs slip into, meter before the present invention is placed on the bottom
Calculate the pressure needing supercharging, afterwards, (on the bank) supercharging program implemented under the premise of anhydrous to this immersible pump, finally, you can
This immersible pump is sunk under water and is energized the diving pump work starting under water.
Illustrate a bit：
When allow immersible pump diving depth less, when on the bank program is pressurized to immersible pump, people can be utilized by rule of thumb
Work inflator is pressurized, if boost pressure is too high, it doesn't matter, and the pressure within immersible pump can be in the period of one considerably long
The interior electric machine shaft gland 7 mainly passing through in the present invention, gas leakage from its underpart outwardly water body, until it reaches external and internal pressure is consistent
Till it is clear that extraneous water body will not pass through electric machine shaft gland 7 enters inside immersible pump.
When allow immersible pump diving depth larger, when on the bank program is pressurized to immersible pump, such as using manually inflating
During cylinder supercharging, preferably relend the help of the blowing pressure display equipment helping assist, by pressure display unit (pressure gauge) i.e.
The pressure value within immersible pump can be observed directly, this is favourable in being accurately finished this supercharging program；Especially incite somebody to action this
Invent when using for deep water with greater need for such.
Four. with regard to the problem of internal liquid molecule could be leaked to external world during present invention work：
If narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 (all structures containing dragging motor) is
It is removeably positioned the upper position of liquid pump 9 by several screws, operationally it is internal for liquid pump 9 now
Liquid is completely can be by dismountable position (screw positioning belongs to non-tight type), the liquid within leakage liquid pump 9 to external world
Body molecule.If the liquid of liquid pump 9 internal flow is water, that is, allow the leakage of water, then, above-mentioned " dismountable side
The structure of formula positioning ", for the use of the present invention, does not have any impact；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,
Just absolutely not permission.The present invention is exactly that the top level structure form aiming at this " absolutely not allowing " takes denomination of invention
, if having made the present invention of this top level structure form, then, also will not be complicated how many on structure manufactures, however,
Purposes aspect, just widely, benefit is in disadvantage.
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 will efficiently and very do not allow fragile on the premise of work.Therefore, by the present invention
Rotor 2 is arranged in narrow metal sealing Isolated Shield 4 or wide type metal sealing Isolated Shield 5 also just to be grown without worry
Period is susceptible to from the problem damaged after running.Generally by the durable apparatus of motor drag, for example：Laundry is mechanical, electrical
Refrigerator and sky wither device, etc., disposably maintenance-free adapted life-span of its dragging motor and part of exerting oneself mostly 15 years with
On, and World Famous Brand then can reach more than 30 years.For this reason, employing non-removable welding in belonging to the present invention of simple products
Technique implementing multiple linkings (so that product can not carry out demolition and maintenance or maintenance), however, can't affect to be approved by people
The single use life-span of the present invention time limit because in the time limit in the single use life-span of immersible pump of the present invention, be not to take
The certainly function of the waterproof seal in the whole machine of immersible pump, and it is depending on not having making of dragging motor in the whole machine of waterproof seal
Use the life-span.
