Abstract
The invention discloses a pump structure capable of enabling liquid molecules in a pump not to be leaked during operation through air jacking sealing and including an immersion pump and an application method of the pump structure. According to the structure, firstly, at least a rotor (2) is surrounded by a narrow metallic seal isolator (4) or a wide metallic seal isolator (5) in a stereoscopic manner, and a motor shaft seal (7), a charging connector mechanism (P) and a pressure display device connector (K) are arranged at the bottom of the narrow metallic seal isolator (4) or the wide metallic seal isolator (5); secondly, the periphery and the bottom for forming a liquid pump (9) are surrounded by a nondetachable metallic seal structure (10) in a stereoscopic manner; and all joint gaps of a full-sealed metallic seal isolation cavity of the pump structure are achieved through a welding process. Due to the fact that the underwater one-time working and idling duration cumulative time of the pump structure depends on the service life (about 30 years) of a motor and the infinite diving depth, and the extremely high cost performance is achieved, conditions are created for the pump structure to become an upgrade product of an immersible pump, and the structure is probably more suitable for a common water pump.
Description
Technical field
Again do not leak when the present invention relates to the use of the sealing operation of air jacking in pump and fluid molecule and (can dive including immersion pump
The depth of water was all can reach infinitely with the time of Dispensable continuous diving) in interior pump configuration and its using method.
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 dynamic
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 inside immersible pump dragging motor.
For this purpose, people are using during 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 1 year diving depth more big then immersible pump), as long as after use, it is necessary for periodically
It is left the water and safeguards (not being corrupted maintenance) by ground, allows the infiltration for coming into inside motor for submerged pump to have an opportunity by artificially
Removing in time, whole motor corrupted is caused to avoid rotor from touching growing number of infiltration.Compact submersible pump this
Many times disembarkation safeguards that eliminating water can still be allowed repeatedly on sample ground, can medium-sized, even Large diving pump so regularly from bank waterborne
Eliminating water is safeguarded, is just had trouble, or even burden is had so that being difficult to be normally used it, for example: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 operational phase;Study carefully
Its reason is exactly to be:Type is bigger, dives under water deeper, and " eliminating water is safeguarded in disembarkation " is just more difficult to, more frequent.
The reason for causing above-mentioned behaviour in service, mainly cause the service intervals time long, is exactly the diving of prior art
Pump waterproof sealing structure, i.e., crucial waterproof seal ring cannot 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 in immersible pump, and by original air in immersible pump
Point passing through waterproof seal ring again by force is extruded immersible pump, it is clear that:Above-mentioned waterproof seal ring has functioned only as delaying air to divide
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 after shutdown, use under water again afterwards, once more
It is placed under water ... ..., until constituting the liquid pump of the immersible pump or dragging motor alternative one, (motor is easiest to bad by contrast
Damage) oneself corrupted is caused after long-term work abrasion and shuts down.I.e.:It is difficult to make immersible pump underwater always
In environment " throughout one's life ".
Furthermore, can be not yet asked directly for a long time at tens meters even in the immersion pump of hundreds of meter of depth underwater work at present
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, are all 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.Prior art let alone water pump is allowed operationally not allow to external world
Leak the problem of its internal hydrone.
Content of the invention
The purpose of the present invention:
It is exactly to overturn the existing waterproof sealing link of immersible pump first from structure to start with (using air jacking sealing original
Reason), and while again solve the problems, such as 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, intends adopting following technical scheme:
The present invention includes in structure:
The dragging motor being made up of the stator of rotor and embedded winding of conventional structure form is by its rotating shaft band
Dynamic liquid pump;
It is characterized in that:
First, at least allow rotor be surrounded with stereogenic by the isolation of narrow metal sealing, or, at least allow rotor with
Both stators are surrounded with stereogenic by the isolation of wide type metal sealing, also, are isolated or wide type metal in narrow metal sealing
The bottom of seal isolation is provided with electric machine shaft gland and inflation nozzle mechanism and pressure-display device interface;
2nd, at least constitute liquid pump around and bottom be by non-removable shape metallic leak-proof structure with stereogenic bag
Round, also, feed liquor interface tube is provided with liquid pump with discharge opeing interface tube;
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 the isolation of wide type metal sealing and shape metallic leak-proof structure are related to
Splicing gap is all to realize connection by non-removable welding procedure.
Described allow rotor to be isolated by narrow metal sealing non-to lead using slim with the cingens part of stereogenic
Magnetic material is serving as, also, narrow metal sealing isolation local is with the internal ring circumferential location of the stator in dismountable tight
Mated condition.
The using method of the present invention, i.e., using front preparation method:
One. one of method:If being intended to for pump to be placed on the use of position below liquid level, first by inflating nozzle mechanism to liquid pump inside
Inflation, is observed by the pressure gauge that pressure-display device interface is connected, or otherwise feels (for example:Using beating manually
During cartridge inflation), after the depth pressure slipped into more than or equal to pump by the blowing pressure, it becomes possible to by the pump be put into liquid level with
Descend and be energized to allow it to start work, now, the fluid molecule that the pump will not be to pump external leakage inside the pump;
Two. the two of method:If being intended to for pump to be placed on the use of position below liquid level, after allowing its energising start work, the pump is same
Also fluid molecule that will not be to pump external leakage inside the pump.
The feature (by taking immersible pump as an example) of the present invention:
One. as 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 for 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 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.Further establish the present invention and can be applied to any diving deeply
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
Ambient pressure when holding immersible pump manufacture) come 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 be penetrated
The strength of part and invalid resist to carry out temporarily sealing in a short time, cause:Prior art must often (regular) disembarkation
(main task be cleaning eliminate infiltration) is safeguarded, and, diving depth is bigger, and periodically debark cycle of maintenance of immersible pump gets over
Short, that is to say, that immersible pump can not be allowed to be constantly in underwater environment the purpose that realizes " throughout one's life ";In order to regular
Hang water surface maintenance, prior art is merely able to be suitable for manufacture be operated in and leave the close small pump of the water surface.
Two. due to the metal that is isolated by narrow metal sealing in present configuration or wide type metal sealing isolation is formed respectively
Seal isolation cavity, is realized being connected by the welding procedure at non-removable welding circle position between shape metallic leak-proof structure
, this fluid molecule that just can realize inside 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 having in this kind of engineering
Require, it is likely to its necessary or prerequisite can be adopted.
The critical defect of prior art is:During normal work, this point, the Standard of water pump are not definitely accomplished
(including all of country) is typically all " permission leaks but can not be exceeded ".
Three. due in " full seal type " the complete machine structure form of special liquid pump in invention with actuating unit, only constituting
Be provided with one be located 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 under liquid extruding is penetrated into, i.e., what gas molecule leaked leads to
Road or gap, this just for 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 for 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 pass through the minimum above-mentioned electric machine shaft gland in position
The gas for applying pressure in pump, and allow in the pump by the external world seep water extruded gas pass through at a slow speed many places on electric machine shaft gland top by
The sealing solid formed by the potted component that the flexible macromolecule class encapsulant being embedded in dedicated optical coulisse gap structure is made
Defence line (cannot stop that gas molecule is passed through to external leakage to the outside of whole machine by sealing coil element), when the extraneous water for penetrating into
Body finally will be contacted simultaneously with rotor after accumulating and progressively replacing the original occupied space of the gas being extruded
Cause its corrupted.
Four. due to not using the potted component entity on conventional meaning in prior art and its knot of adapted in the present invention
Structure, seals only with the gas jacking principle of potted component entity is not needed, will cause existing on population structure
The integrally-built change of immersible pump or simplification, however, its sealing performance has but much surmounted prior art (reached definitely
The degree of sealing), for this purpose, " cost performance " of the present invention will necessarily be much larger than prior art, this just can at least become for the present invention
Condition is created for the regeneration product of prior art immersible pump.Meanwhile, it is suitable for most common water pump structure.
The critical defect of prior art is:Due to the potted component entity set by it and its adapted structure no
Method prevents penetrating for gas molecule or fluid molecule, and only up to the purpose that transmission rate slows down, i.e., internally seep water reduced rate
Some, therefore, on complete machine structure, finally wait its destiny, it is likely that can exactly allow existing immersible pump structure by this
Bright superseded.
Five. as the present invention can slip into required any depth position under water in engineering, and which continues under water
Time (contain:The time of work and the time of inoperative) infinitely great (exclusion during this period can be reached without the need for periodically disembarkation
The maintenance of infiltration), so, immersible pump of the present invention just can as needed or manufacturing capacity make required for 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
The submarine oil that adopts is taken away, or, it is efficiently to exploit " combustible ice " for enriching on the earth under water (not yet to solve to enter at present
Enter exploitation the method for commercial object on a large scale 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
Using best material produce its life-span can reach be close to 50 years or longer).
The critical defect of prior art is:The ring structure that produces 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, dive under water in immersible pump
Deeper, then under the premise of periodically disembarkation excludes the shorter weak tendency performance of the maintenance period for seeping water, if making extra heavy diving
Pump is difficult to often disembarkation and carries out periodic maintenance to exclude infiltration.

Specific embodiment
By taking immersible pump as an example, core overview of the present invention:In order to avoid rotor 2 is taken care of the pence inside immersible pump with penetrating into
The contact of extraneous water body and finally damaged motor, at least define the three-dimensional metal sealing for surrounding property to rotor 2
Isolated Shield cavity, and, the only rotating shaft 6 of the rotor 2, revolving force is exported to liquid pump 9 by axle envelope position 7, it is clear that
If extraneous water body is intended to enter the cavity (inner chamber) of metal sealing Isolated Shield formation and contact with rotor 2, only have
Axle envelope position 7 is passed through upwards along rotating shaft 6 to enter, as long as however, the air pressure in the Isolated Shield cavity is enough
Greatly, it is to be fully able to from top to bottom jacking to live, prevent:
Extraneous water body from bottom to top pass through above-mentioned gap minimum and add by macromolecule flexible material potted component institute
The axle envelope position 7 of composition and enter in the Isolated Shield cavity.
According to above explain the main points briefly and accompanying drawing signal, it should be substantially appreciated that the mechanism of the present invention, with
Under explanation further below is remake for the involved related keyword particular problem of implementing of the technology of the present invention:
One. the formation problems of the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield 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) composition narrow metal sealing Isolated Shield for making of non-magnet material (have drawn from rustless steel or pyrite, etc.)
The Part portions of 4 entirety;And other positions of the narrow metal sealing Isolated Shield 4 can adopt abundant material to produce,
The magnitude that its thickness is several millimeters can be taken (thickness in general little medium-sized immersible pump can adopt 2 millimeters);And constitute 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
The phenomenon (avoid rosin joint or dry joint technically very ripe) of existing rosin joint or dry joint, finally the becoming of the narrow Isolated Shield 4
Type can be implemented the method for the last assembly of integral solder to realize after installing using local again.Purpose is:Allow assembly
The 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 prevented) beyond monolithic devices cannot all penetrate by gas molecule or fluid molecule are close
Metallic cavity, the only metallic cavity, that is, constitute the gap between the metallic molecule of the narrow metal sealing Isolated Shield 4, be
Diameter less than general gas flow molecule or fluid molecule.
As motor stator 1 is isolated by narrow metal sealing Isolated Shield 4 with both rotors 2 so that with respect to appearance
The motor stator 1 of flimsy cincture winding becomes detachable, but it is difficult suitably to increase some in manufacture
Degree.By contrast, motor stator 1 and motor stator 1 are both enclosed in which by wide type metal sealing Isolated Shield 5
In, it be manufactured just simple how, 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:
As 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 is:The gap of splicing therein or connection is solved by metal welding procedure,
This just necessarily causes both of splicing or connection to define the structure of " full seal type ", i.e., utterly can prevent gas molecule or
Fluid molecule is penetrated from the position of welding.
If, certain position of the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield in the present invention
It is to implement to seal by the fastening of bolt using the encapsulant of dismountable one class of nonmetallic rubber, then, the isolation
Air molecule in shielding cavity still can be penetrated away from above-mentioned flexible non-metallic encapsulant, be its transmission rate
May be slowly.For example:The bicycle tube that is produced by macromolecular material do not inflated with doughnut for a period of time be not
Row, it is clear that this is excessive and cannot prevent gas molecule therefrom low rate due to constituting the distance between molecule of the material
Pass through, and exactly this " passing through ", define " fatal " for the waterproof sealing structure of prior art, i.e.,: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 for passing through, that is, do not play a part of real waterproof sealing.
If the 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield 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 the Isolated Shield cavity still can be from wearing between the metal flat of above-mentioned two unusual light
It is saturating that (its smooth gap that presses that smooth any plane all has roughness again cannot prevent wearing for gas molecule
Thoroughly), be its transmission rate may slowly some.
Above two " if " example fully demonstrate why prior art immersible pump is existed in " background technology "
Described " being difficult to " or problem that under water can not " throughout one's life ", and cannot prevent outside the fluid molecule in liquid pump 9
The problem that lets out.This obviously at least due to:The removable seal structure for adopting in its key position in prior art
(for example:Polymeric seal element) reason that gas molecule or fluid molecule are penetrated 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
" full seal type " of oneself is showed, and has been guaranteed 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 probability that the position (top) in addition to bottom of cavity is let out, 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 the simple metal seal cavity by above-mentioned 7 position of electric machine shaft gland for allowing fluid molecule to pass through
Chance or probability, be finally to ensure that:Rotor 2 can not possibly touch the accumulation water body for penetrating from the external world and
Motor corrupted is made, i.e.,:Define 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 " external world water body infiltration 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
Rubber (containing minimum gap) of the less area for example as soft macromolecular material is contacted with extraneous water body, for example:
7 position of electric machine shaft gland, and inflation nozzle mechanism P (similar to the structure of the charging connector that inflates for bicycle tube) shown with pressure
Device interface K (similar to the structure of basketball charging connector), showing for accompanying drawing (is referred in the bottom for being exactly located at the seal cavity
Meaning).Obviously, aforesaid three (electric machine shaft gland 7, the inflation nozzle mechanism P and device interface K) is all to prevent fluid from dividing
Son is therefrom passed through, and other positions in the seal cavity, i.e., the position in addition to bottom is to arrange permission stream
Any element that body molecule can be passed 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:
Latent 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 preventing fluid molecule from passing through its waterproof sealing three-dimensional defense line.
Obviously, " air jacking " principle formed in present configuration, can exactly reach utterly from prevention fluid
The effect of three-dimensional waterproof sealing is defined in the aspect of molecule " passing through ".Realize so long as not from the aspect of fluid molecule
" absolute " two words, just exist allowing the restriction immersible pump technology of immersible pump " periodically eliminating water is safeguarded in disembarkation " to develop unavoidably and give people
Manufactured the conventional program of very burden.
Due to present invention achieves " air jacking " principle, eliminates the mechanism of various potted components and its adapted, latent
Will necessarily occur 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:
There is the inflation being connected by inflation connecting leg 12 with the bottom of above-mentioned metal sealing Isolated Shield cavity in the present invention
Nozzle mechanism P, if necessary, can also increase using auxiliary and with the inflation connection of connecting leg 12 inflation pressure display device interface
K, inflation nozzle mechanism P similar to the charging connector for arranging on such as bicycle tube (gas is only accurate and then is forbidden), the inflation
Pressure-display device interface K can also (gas can both enter to have using the simplest pin type charging connector interface shape as on basketball
Can go out);Both settings are to aim at:Before the present invention, it is ensured that inside immersible pump, i.e., in metal sealing Isolated Shield cavity
Pressure more than or equal to the immersible pump place depth of water pressure.There is no above-mentioned inflation nozzle mechanism P and pressure in prior art
Power display device interface K.
Typically can be by rule of thumb using manually (for example:Using inflator as beaten degree sufficient bicycle tube
Reach the degree for allowing immersible pump dive under water about tens meters to hundred meters or so) or electric inflator (that for preferably having pressure to show)
Or the angry technological means such as bag of reacting of chemistry realize the supercharging inside for immersible pump, generally before diving is using immersible pump
Supercharging reaches the pressure more than or equal to the immersible pump place depth of water, for example:
10 meters of diving equivalent to an atmospheric pressure, i.e.,:1 kgf/centimetre2;
100 meters of diving equivalent to ten atmospheric pressures, i.e.,:10 kgfs/centimetre2;
Obviously, it was accomplished by before the present invention is placed on the bottom measuring the water-bed depth that the immersible pump needs to slip into, meter
Calculating needs the pressure of supercharging, and afterwards, to the immersible pump, (on the bank) implements supercharging program under the premise of anhydrous, finally, you can
The immersible pump is sunk under water and is energized startup diving pump work under water.
Illustrate a bit:
When allowing, the diving depth of immersible pump is little, when being pressurized program on the bank to immersible pump, can be by rule of thumb using people
Work inflator is pressurized, if boost pressure is too high, it doesn't matter, and the pressure inside immersible pump can be in the period of one considerably long
Interior mainly by the electric machine shaft gland 7 in the present invention, from gas leakage 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 and enter inside immersible pump.
When allowing, the diving depth of immersible pump is larger, when being pressurized program on the bank to immersible pump, such as using manually inflating
During cylinder supercharging, the help of the blowing pressure display equipment for helping aid in preferably is relended, by pressure display unit (pressure gauge) i.e.
The pressure value inside immersible pump can be observed directly, this is favourable in the supercharging program is accurately finished;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 4 or wide type metal sealing Isolated Shield 5 (all structures containing dragging motor) of narrow metal sealing Isolated Shield is
The upper position of liquid pump 9 is removeably positioned by several screws, operationally which is internal for liquid pump 9 now
Liquid is can to leak the liquid inside liquid pump 9 to external world by dismountable position (screw positioning belongs to non-tight type) completely
Body molecule.If the liquid of 9 internal flow of liquid pump is water, that is, allow the leakage of water, then, above-mentioned " dismountable side
The structure of formula positioning " does not have any impact for the use of the present invention;If the liquid of 9 internal flow of liquid pump is valuable
Or extremely hazardous flowing material, then, the structure of above-mentioned " dismountable mode is positioned " for the use of 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, also will not be complicated how many in structure manufacture, however,
In terms of purposes, just widely, benefit is in disadvantage.
In sum:
In general, motor is a highly developed product, if guarantee rotor therein 2 be all the time in atmosphere
Rotary work, then, motor will efficiently and do not allow very much fragile on the premise of work.Therefore, by the present invention
Rotor 2 is arranged in 4 or wide type metal sealing Isolated Shield 5 of narrow metal sealing Isolated Shield also just to be grown without worry
It is susceptible to from the problem that damages after period operation.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 purpose, 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 be depending on without the making of dragging motor in the whole machine of waterproof seal
Use the life-span.
