As shown in figure 10, fracture portion 91 is configured to form the thinner wall section 92 of its wall thickness from the outstanding part of the outer surface of the pedestal part 10 of the crown face 100e side that is provided with bolt head 100a.Thinner wall section 92 is as long as cover bolt head 100a, and the fracture portion 91 that is in scope following scope, that promptly contacted with an opposite side of the screw rod 100b face that is provided with of bolt head 100a gets final product for thin-walled.In addition, the wall thickness of the thinner wall section 92 of fracture portion 91, as shown in figure 11, so long as applying under the situation of load (stress) to screw rod 100b with hammer H etc., the thickness of 92 fractures of thinner wall section at least of fracture portion 91 gets final product.Therefore, can suitably set its thickness according to pedestal part 10 employed resin materials.
The nut insertion hole 26d of fixed mechanism 26 and bolt-inserting hole 26c form a pair of, have to be configured to the patchhole that can screw togather with the bolt B that is inserted into bolt-inserting hole 26c.In addition, nut insertion hole 26d is arranged on the surface of pedestal part 10.At this, shown in Fig. 2,5, nut insertion hole 26d is not arranged on the inserting side of bolt B to bolt-inserting hole 26c, and is arranged on from the surface of outstanding (perforation) side of bolt-inserting hole 26c.
The water supply device 1 of Gou Chenging are carried out following setting like this, at first, suck flange 70 by pipe arrangement etc. with well, be connected by water layer.Then, discharge flange 71 and the object that feeds water is connected by pipe arrangement etc.And the feed cable 16c of transducer 16 is connected with domestic power supply.
Then, when the user sends when indication running to transducer 16, to motor 12 supply capabilities, motor 12 is driven by transducer 16.By drive motor 12, running shaft 12a rotation connects or the impeller 57 that is fixed on this running shaft 12a rotates along with running shaft 12a.
Water when turning round last time etc. is got lodged in by one-way valve 72a and sucks flange 70 and water is full of under situation pump case 34 in, and shown in the mobile F of Fig. 5,6,8 water, water passes through after impeller 57 superchargings by force feed.At this moment, water is pressed to self-priming portion 11 from the tap hole portion 60 of inner casing 58 via the tap hole 33 of pump case 34.
The water that is pressed to self-priming portion 11 moves to second space 44 from first space 43 via gas-liquid separation plate 41, is sent to detector 15 from opening portion 35.The water that is sent to detector 15 moves to exhaust port 39 from the opening portion 37 of detector 15 via interconnecting part 38.Like this, when passing through the impeller 57 force feed water of pump 13, inlet hole 32 sides (first side) of pump case 34 become low pressure, open one-way valve 72a.By opening one-way valve 72a, water is inhaled in the inner casing 58 from the inlet hole 32 of the pump case 34 inlet hole portion 59 via inner casing 58.By this repeatedly, water is pressed to the downstream side, supplies water from discharging flange 71.
In addition, if water is sucked to inner casing 58, then from inner casing 58 discharge waters the time, water is immersed in the gap of pump case 34 and inner casing 58.But, the double binder of doing Sealing of coating between pump case 34 and inner casing 58.In addition, protuberance 34a and recess 58a are chimeric.Therefore, water can not move between pump case 34 and inner casing 58.
In addition, the water of discharging from pump case 34 by detector 15 time, detects the water yield and in the pressure at least one of the water of force feed, and this testing result sends to transducer 16 via signaling line S1.Transducer 16 changes the discharge capacity of pump 13 based on this testing result control motor 12.Make water supply device 1 running by this repeatable operation.
Then, first when running after water supply device 1 are provided with etc., in the pump case 34 with suck the pipe arrangement that flange 71 is connected in be full of and only accumulate under the situation of a spot of water in air or the pump case 34, the mobile of water and air that comprises self-priming at this moment described.
At first, the user unloads the piston P of water injection hole 36a, to inject water in suction-chamber 36.Shown in the mobile F1 of Fig. 6,8 water, the water of injection moves in pump case 34 (adverse current) from the tap hole portion 60 and the reverse flow hole portion 61 of tap hole 33 via inner casing 58.
Like this, carry out water filling, make be full of water in the pump case 34 after, piston P and water injection hole 36a are screwed togather, the running pump 13.Utilize pump 13 with the water in the pump case 34 (inner casing 58) from tap hole portion 60 to first space of 36 inside, 43 force feeds from the suction-chamber.The water that is compressed to first space 43 surpasses from the suction-chamber top of 36 the second board 41b, moves to second space 44.
Like this, when utilizing pump 13 force feed water, the pressure of inlet hole 32 sides becomes low pressure with respect to the pressure of the upstream side that sucks flange 70.Therefore, one-way valve 72a opens, and the air of the pipe arrangement that is connected with suction flange 70 is drawn into pump case 34.Inhaled air mix with the water of pump case 34 and by pump 13 force feeds to from the suction-chamber 36 first space 43 move (force feed).
The air that moves to first space 43 is moved upward than preferentially with water, therefore move to second space 44, and the opening portion 35 of side moves downstream from it.At this moment, by the water of force feed, a part is trapped in first space 43 with air, and remaining moves to second space 44.Move to the water in second space 44, because air preferentially moves downstream from opening portion 35, so the water of a part moves downstream from opening portion 35, other hydropexis is in second space 44, and from reverse flow hole portion 61 adverse current in pump case 34 once more shown in the mobile F1 of water.
Utilize moving of such water, can prevent from pump case 34, to be full of air the more water of sustainable supply in pump case 34.Like this, from pump 13 to being arranged on air the pipe arrangement that sucks on the flange 70 by force feed downstream successively.Thus, though in the fluid of suction pump 13 entrained gas, can or not make pump 13 be absorbed in function stop because of the self-priming that self-priming portion 11 is carried out yet.
Then, the situation to the pedestal part 10 of discarded water supply device 1 describes.
At first, remove fixed mechanism 26 and and the paired bolt B of fixed mechanism 26, nut N between screw togather, and unload the formation product that are fixed on the pedestal part 10, i.e. pump 13, accumulator 14, detector 15, transducer 16 and lip part 17 from pedestal part 10.Then, unload nut N and the bolt B that is arranged on the pedestal part 10.In addition, unscrew the screw thread S of the lower surface that is arranged on pedestal part 10, unload self-priming chamber cap 42.
Under this state, as shown in figure 11, apply load F to the stud bolt 26b that is arranged on the pedestal part 10 with hammer H etc.The stud bolt 26b of F of being subjected to loading applies load F by its bolt head 100a to the thinner wall section 92 of fracture portion 91.Thinner wall section 92 is owing to this load F ruptures.That is, apply load, make 91 fractures of fracture portion above the load limit of thinner wall section 92 by utilizing hammer H.
Because the fracture of this fracture portion 91,10 fixing stud bolt 26b are disengaged fixing by pedestal part.In addition, bolt head 100a and screw rod 100b are passed through from fracture portion 91, thereby remove, can unload stud bolt 26b by fixing that this pedestal part 10 is carried out.Like this, by unloading stud bolt 26b, can separately discard pedestal part 10 that forms by resin material and the stud bolt 26b that forms by metallic material.
According to the water supply device 1 of such formation, the double binder of doing Sealing of coating between pump case 34 and inner casing 58, and then, make as the protuberance 34a and the recess 58a of limitation part 29 chimeric.Thus, can enough simple structures prevent the common rotation that causes by impeller 57 of inner casing 58.Particularly, inner casing 58 usefulness protuberance 34a and recess 58a be physical property ground (constructivity) restriction on common sense of rotation, thereby can prevent common rotation effectively.
At this moment, as long as according to stress, set suitably that size shape and the number of protuberance 34a and recess 58a gets final product in the limitation part 29 in the common sense of rotation in the edge inferior generation of operating pressure, that 57 pairs of inner casings 58 of impeller apply of pump 13.In addition, as long as,, can design protuberance 34a and recess 58a so can not increase machining period and manufacture cost because size shape and the number of these protuberances 34a and recess 58a are appended in each molding die.
In addition, can block water flowing between the gap of pump case 34 and inner casing 58 effectively by double binder and the limitation part 29 of doing Sealing.This is for following misgivings: as the leakage of water, if the gap of water by between pump case 34 and inner casing 58, producing by tolerance of size etc., the water that then is not pressurized might be from the upstream side shifting downstream.In addition, similarly, the possibility that also exists the water be pressurized to move from the low upstream side of downstream lateral pressure.Therefore, also might carry out force feed with the hydraulic pressure of regulation.The such pump case 34 and the leakage of the water between the inner casing 58 also become the reason that pump efficiency reduces.
But, by between pump case 34 and inner casing 58, limitation part 29 being set, the leakage that the enough protuberance 34a of energy block water.Because protuberance 34a and recess 58a engage by chimeric, so water can be in the Clearance Flow of limitation part 29.Particularly, between the adjacent inlet hole 32 and tap hole 33, because its pressure reduction, the possibility of leakage is higher around pump case 34 and inner casing 58.But,, improve reliability by utilizing the leakage of limitation part 29 at textural anti-sealing.
In addition, utilize the double binder of doing Sealing can prevent more effectively leaking the gap of sealing between pump case 34 and inner casing 58.
Like this, utilize binder and limitation part 29 also can prevent the leakage of sealing effectively, prevent the reduction of pump efficiency.
In addition, under the situation of not using binder, by blocking between inlet hole portion 59 and the tap hole portion 60, also have the effect that this pump efficiency is reduced.That is, under the situation of not using binder, there is the possibility between water immersion pump case 34 and the inner casing 58.But the pump case 34 of the stream that leaks as water and the flow path area of the water between the inner casing 58 are little, and distance is also long.Therefore, the pressure of water reduces, and water also moves hardly.Like this, even water is moved, compare with the situation that water moves between inlet hole portion 59 and tap hole portion 60, its amount of movement is minimum, and the reduction amount of pump efficiency is minimum.
That is,, can prevent the moving of water between inlet hole portion 59 and the tap hole portion 60 by making protuberance 34a and recess 58a chimeric.Thus, the positive effect that has the reduction of the pump efficiency of preventing.
In addition, pedestal part 10 by will be as the suction passage portion 31 of stream portion 21, pump case 34, from suction-chamber 36, interconnecting part 38 and discharge that stream portion 40 is one-body molded by resin to be formed on base body 20.Like this, pedestal part 10 can reduce molding procedure by base body 20 and stream portion 21 are formed as one, and reduces components number, reduces manufacture cost.
In the past, in such water supply device, by being fixed on the base and used by the integrally formed pump case of metal, suction passage, discharge stream and channel member from the suction-chamber.
But, with metal integrally formed channel member, and then being fixed under the situation on the base, the Heavy Weight of channel member becomes the reason that the weight that makes water supply device self increases.In addition, because with the one-body molded channel member of metal, so the manufacture cost of material cost and casting expense etc. also uprises.And then the parts expense and the assembly expenses that are used for channel member is fixed on bolt on the base etc. also increase.
In addition, integrally formed such each constitutes the structure of product, needs to consider molding etc.Particularly as self-priming portion 11 a part of openings, when portion's moulding within it has the space of volume of regulation, need to consider molding etc., or use the fusion core.Under the situation of carrying out molding, as self-priming portion 11, portion has the space within it, extracts the core not a duck soup from the shape of opening portion less than the volume of inner space.In addition, under the situation of using the fusion core, because the fusion core is once using the back fusion, so expense uprises.
But pedestal part 10 adopts 36 the forming as one with pedestal part 10 from the suction-chamber of self-priming portion 11, and the structure of self-priming chamber cap 42 is set in addition, thereby 36 the molding from the suction-chamber can be carried out molding from the opening portion of 36 the bottom from the suction-chamber.Therefore, pedestal part 10 can be with base body 20 and stream portion 21 by resin and one-body molded.
Like this, if come moulding self-priming chamber cap 42 with the form of split, be assembled in suction-chamber 36 by bolt B etc., then can form pedestal part 10, the assembling procedure of self-priming portion 11 also is compressed to inferior limit.In addition, by 36 etc. stream portion 21 forms as one with pedestal part 10 and pump case 34 with from the suction-chamber, can reduce the manufacturing procedure of casting and resin forming processing etc., and can reduce the assembling man-hour of each formation product.In addition, owing to,, can make pedestal part 10 lightweights so compare with the situation of casting with metallic material by the integrally formed pedestal part 10 of resin.In addition, when forming pedestal part 10 by resin, owing to also form the muscle 22 of the enhancing usefulness of pedestal part 10, so can strengthen pedestal part 10.
As long as the mould that disposable making pedestal part 10 moulding are used can carry out the moulding of pedestal part 10, and be applied in the volume production.In addition, to compare resin material cheap with metallic material.Therefore, can reduce the manufacture cost of pedestal part 10.Thereby the manufacture cost of water supply device 1 also reduces.
In addition, on pedestal part 10, metallic material can only use bolt B and nut N etc., can realize the lightweight of pedestal part 10.Thus, use the water supply device 1 of pedestal part 10 light weight that also becomes.Particularly, such water supply device 1 are used for the various uses of home-use well and water reception tank etc., therefore operator not only, and also the user is provided with place etc. according to the changes of using such as situation.
Such setting operation, for example operator or user unload the pipe arrangement that is connected with water supply device 1, directly carry water supply device 1.Therefore, by making water supply device 1 lightweight, the operator can easily carry water supply device 1, also improves operation.
In addition, as shown in Figure 3, can directly each be constituted product and dispose or be fixed on the pedestal part 10.Therefore, can make water supply device 1 become small-sized.In addition, water supply device 1 by with cover 4 covering base portions 10, can protect each formation product that is arranged on the pedestal part 10 of main part 2 not to be subjected to external action.
In addition, embed forming section 90, at least a portion of the bolt head 100a of stud bolt 26b and axial region 100c is embedded the inside of pedestal part 10, thinner wall section 92 is set in the fracture portion 91 corresponding with bolt head 100a.By thinner wall section 92 is set, when applying load F to stud bolt 26b, can be from easily make 91 fractures of fracture portion from thinner wall section 92.Thus, can easily separate (disengaging) stud bolt 26b from pedestal part 10.
Specifically, embed forming section 90 and embed stud bolt 26b by being pressed into when being shaped or after being shaped, hot pressing is gone into etc.Therefore, the roughly whole zone of the outside that is positioned at pedestal part 10 of stud bolt 26b is covered by resin material.
In addition, by the pedestal part 10 of molding resin material since need with water supply device 1 necessary each constitute product and be positioned on the pedestal part 10, so pedestal part 10 is formed by the resin material of intensity with regulation and hardness.Therefore like this, pedestal part 10 employed resin materials have the intensity and the hardness of regulation, and the stud bolt 26b that covers the whole zone that is positioned at pedestal part 10 with resin material is firmly fixed.
That is, with at least a portion embedding of axial region 100c axial region 100c and bolt head 100a etc., stud bolt 26b, can have necessary strength by only.
Specifically, stud bolt 26b to need only to apply direction (from the direction of screw rod 100b to bolt head 100a) with bolt head 100a restriction stud bolt 26b to load and moves in order easily to separate.
Because resin material self has the intensity and the hardness of regulation, so if cover the enlarged areas of stud bolt 26b with resin material, then stud bolt 26b can be fixed more firmly.Particularly,, and cover, then on the position of the covering screw section of pedestal part 10 100d, formed internal thread part by resin material to screw section 100d if resin material not only covers bolt head 100a and axial region 100c.
Thus, in the 100d of screw section, the screw thread mountain of screw section 100d and the internal thread part that is formed on the pedestal part 10 become the state that screws togather, and the resinous internal thread part by screw section 100d and pedestal part 10 also can limit load and apply moving of direction.
That is,,, and, all resist the load F that applies at the internal thread part of screw section 100d and pedestal part 10 not only in bolt head 100a and fracture portion 91 applying load to stud bolt 26b during F.Therefore, the fracture portion needed load of 91 fractures is become greater to beyond the expection, the load limit that the load of pedestal part 10 peripheries of supporting stud bolt 26b applies on the direction increases.
Particularly, in such screw division 100d, when applying load F, apply and make the needed load of fracture portion 91 fractures, need to surpass the load of the shearing stress on the internal thread part of pedestal part 10.In addition, increase, then follow the needed load of the female screw division of shearing pedestal part 10 therewith to increase if embed the length of the screw section 100d of pedestal part 10.
But, embed forming section 90, for the stud bolt 26b that embeds pedestal part 10, at least a portion embedding with stud bolt head 100a and axial region 100c is exposed externally screw section 100d fully.Therefore, stud bolt 26b can be securely fixed on the pedestal part 10, and stud bolt 26b and pedestal part 10 separately the time needed load F only get final product for the load of thinner wall section 92 fractures that can make fracture portion 91.
Like this, embedding forming section 90 does not need to use special worker's method, and the intensity that reduces of the damaged life-span can have the use that can not make water supply device 1 time.In addition, can easily separate stud bolt 26b and pedestal part 10.And then, owing to when pedestal part 10 moulding, can embed stud bolt 26b,, the manufacture cost of product is reduced so can not increase manufacturing procedure.
In addition, by improving separately disposability, can reduce obsolescence cost.Just can improve and separate disposability owing to only fracture portion 91 is set, so also can improve the degrees of freedom of design at the embedding forming section 90 of pedestal part 10 (plastic article).
