That is, stud bolt 26b when nut N and screw section 100d are screwed togather, as long as its bolt head 100a and the inside butt that embeds forming section 90 (base portion 10) can pin rotating force, does not get final product so that stud bolt 26b does not rotate (idle running) jointly.Therefore, the shape of the bolt head 100a of stud bolt 26b can suitably be set.
As shown in figure 10, fracture section 91 is configured to form the thinner wall section 92 of its wall thickness from the outstanding part of the outer surface of the base portion 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 section 91 that is in scope following scope, that namely contact 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 section 91, as shown in figure 11, so long as in the situation that apply load (stress) with hammer H etc. to screw rod 100b, the thickness of at least thinner wall section 92 fractures of fracture section 91 gets final product.Therefore, can suitably set its thickness according to base portion 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 base portion 10.At this, shown in Fig. 2,5, nut insertion hole 26d is not arranged on bolt B to the inserting side of 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 that consist of like this are carried out following setting, at first, suck flange 70 by pipe arrangement etc. with well, be connected by water layer.Then, discharge flange 71 and the object that is connected by connections such as pipe arrangements.And the feed cable 16c of transducer 16 is connected with domestic power supply.
Then, when the user sent the running indication to transducer 16, to motor 12 supply capabilities, motor 12 was 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 in 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 section 11 from the tap hole section 60 of inner casing 58 via the tap hole 33 of pump case 34.
The water that is pressed to self-priming section 11 moves to second space 44 from the 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 section 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 when discharging water from inner casing 58, 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 arrange etc., in the pump case 34 with suck the pipe arrangement that flange 71 is connected in be full of and only accumulate in the situation of a small amount 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 the 36 interior injected waters from the suction-chamber.Shown in the mobile F1 of Fig. 6,8 water, the water of injection is from tap hole section 60 and the reverse flow hole section 61 of tap hole 33 via inner casing 58, in pump case 34 interior movements (adverse current).
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 first space 43 force feeds of water from tap hole section 60 to 36 inside from the suction-chamber in the pump case 34 (inner casing 58).The water that is compressed to the first space 43 surpasses from the suction-chamber top of the second board 41b of 36, 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 intake of the pipe arrangement that is connected with suction flange 70 is to pump case 34.The air that sucks mix with the water of pump case 34 and by pump 13 force feeds to from the suction-chamber the first space 43 of 36 move (force feed).
The air that moves to the 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 the first space 43 with air, and remaining moves to second space 44.Move to the water of second space 44, because air is preferentially mobile downstream from opening portion 35, so the water of a part is mobile downstream from opening portion 35, other hydropexis is at second space 44, and from reverse flow hole section 61 shown in the mobile F1 of water again to pump case 34 interior adverse currents.
Utilize the movement of such water, can prevent from pump case 34, being full of air, to the more water of pump case 34 interior sustainable supplies.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 section 11 carries out yet.
Then, the situation of the base portion 10 of discarded water supply device 1 described.
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 base portion 10 from base portion 10, i.e. pump 13, accumulator 14, detector 15, transducer 16 and lip part 17.Then, unload nut N and the bolt B that is arranged on the base portion 10.In addition, unscrew the screw thread S of the lower surface that is arranged on base portion 10, unload self-priming chamber cap 42.
Under this state, as shown in figure 11, apply load F with hammer H etc. to the stud bolt 26b that is arranged on the base portion 10.The stud bolt 26b of F of being subject to loading applies load F by its bolt head 100a to the thinner wall section 92 of fracture section 91.Thinner wall section 92 is owing to this load F ruptures.That is, apply load above the load limit of thinner wall section 92 by utilizing hammer H, make 91 fractures of fracture section.
Because the fracture of this fracture section 91,10 fixing stud bolt 26b are disengaged fixing by base portion.In addition, bolt head 100a and screw rod 100b are passed through from fracture section 91, thereby remove by fixing that this base portion 10 is carried out, can unload stud bolt 26b.Like this, by unloading stud bolt 26b, can separately discard the base portion 10 that is formed by resin material and the stud bolt 26b that is formed 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 protuberance 34a and the recess 58a of restriction section 29 chimeric.Thus, can enough simple structures prevent the common rotation that is caused by impeller 57 of inner casing 58.Particularly, inner casing 58 usefulness protuberance 34a and recess 58a be physically (constructivity) restriction on common sense of rotation, thereby can prevent effectively common rotation.
At this moment, as long as according to the stress 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, set suitably that size shape and the number of protuberance 34a and recess 58a gets final product in the restriction section 29.In addition, as long as because size shape and the number of these protuberances 34a and recess 58a are appended in each molding die, so can not increase machining period and manufacture cost, can design protuberance 34a and recess 58a.
In addition, can block effectively water flowing between the gap of pump case 34 and inner casing 58 by double binder and restriction section 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, being produced 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.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, restriction section 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 restriction section 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, by utilizing restriction section 29 in the leakage of textural anti-sealing, improve reliability.
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 restriction section 29 also can prevent effectively the leakage of sealing, prevent the reduction of pump efficiency.
In addition, in the situation that do not use binder, by blocking between inlet hole section 59 and the tap hole section 60, also have the effect that this pump efficiency is reduced.That is, in the situation that do not use 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 decreased of water, water are also mobile hardly.Like this, mobile even steeping in water for reconstitution is given birth to, to compare with the situation that water moves between inlet hole section 59 and tap hole section 60, its amount of movement is minimum, and the reduction amount of pump efficiency is minimum.
That is, by making protuberance 34a and recess 58a chimeric, can prevent the movement of the water between inlet hole section 59 and the tap hole section 60.Thus, the positive effect that has the reduction of the pump efficiency of preventing.
In addition, base portion 10 by will be as the suction passage section 31 of stream section 21, pump case 34, from suction-chamber 36, interconnecting part 38 and discharge stream section 40 and be molded on the base body 20 by resin integrated and form.Like this, base portion 10 can reduce molding procedure by base body 20 and stream section 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 by the integrally formed pump case of metal, suction passage, discharge stream and the channel member from the suction-chamber and used.
But, with metal integrally formed channel member, and then being fixed in 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 structure that respectively consists of product needs to consider molding etc.When a part of opening as self-priming section 11 particularly, section's moulding within it have the space of volume of regulation, need to consider molding etc., or use the melting core.In the situation that carry out molding, as self-priming section 11, section 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, in the situation that use the melting core, because the melting after once using of melting core, so expense uprises.
But base portion 10 adopts 36 the forming as one with base portion 10 from the suction-chamber of self-priming section 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, base portion 10 can be with base body 20 and stream section 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 base portion 10, the assembling procedure of self-priming section 11 also is compressed to inferior limit.In addition, by 36 etc. stream section 21 forms as one with base portion 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 that respectively consists of product.In addition, owing to by resin integrated shaping base portion 10, so compare with the situation of casting with metallic material, can make base portion 10 lightweights.In addition, when forming base portion 10 by resin, owing to also form the muscle 22 of the enhancing usefulness of base portion 10, so can strengthen base portion 10.
As long as the mould that disposable making base portion 10 moulding are used can carry out the moulding of base portion 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 base portion 10.Thereby the manufacture cost of water supply device 1 also reduces.
In addition, on base portion 10, metallic material can only use bolt B and nut N etc., can realize the lightweight of base portion 10.Thus, use the water supply device 1 of base portion 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 arranges place etc. according to the changes such as situation of using.
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 workability.
In addition, as shown in Figure 3, can directly each formation product be configured or be fixed on the base portion 10.Therefore, can make water supply device 1 become small-sized.In addition, water supply device 1 by with cover 4 covering base sections 10, can protect each formation product that is arranged on the base portion 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 base portion 10, in the fracture section 91 corresponding with bolt head 100a thinner wall section 92 is set.By thinner wall section 92 is set, when applying load F to stud bolt 26b, can be from easily make 91 fractures of fracture section from thinner wall section 92.Thus, can easily separate (disengaging) stud bolt 26b from base portion 10.
Specifically, embed forming section 90 and embed stud bolt 26b by being pressed into when being shaped or after being shaped, hot pressing enters etc.Therefore, the roughly whole zone of the outside that is positioned at base portion 10 of stud bolt 26b is covered by resin material.
In addition, by the base portion 10 of molding resin material, owing to water supply device 1 necessary each formation product need to be positioned on the base portion 10, so base portion 10 is formed by the resin material of the intensity with regulation and hardness.Like this, base portion 10 employed resin materials have intensity and the hardness of regulation, and the stud bolt 26b that therefore covers the whole zone that is positioned at base portion 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 intensity by only.
Specifically, stud bolt 26b needs only to apply direction (direction from screw rod 100b to bolt head 100a) with bolt head 100a restriction stud bolt 26b to load mobile in order easily to separate.
Because resin material self has 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, if resin material not only covers bolt head 100a and axial region 100c, and be covered to screw section 100d, then on the position of the covering screw section of base portion 10 100d, formed internal thread part by resin material.
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 base portion 10 become the state that screws togather, and the resinous internal thread part by screw section 100d and base portion 10 also can limit the movement that load applies direction.
That is, applying load to stud bolt 26b during F, not only in bolt head 100a and fracture section 91, and at the internal thread part of screw section 100d and base portion 10, all resist the load F that applies.Therefore, the fracture section needed load of 91 fractures is become greater to beyond the expection, the load limit that the load of base portion 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 section 91 fractures, need to surpass the load of the shearing stress on the internal thread part of base portion 10.In addition, increase if embed the length of the screw section 100d of base portion 10, then follow the needed load of the female screw division of shearing therewith base portion 10 to increase.
But, embed forming section 90, for the stud bolt 26b that embeds base portion 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 base portion 10, and stud bolt 26b and base portion 10 separately the time needed load F only get final product for the load of thinner wall section 92 fractures that can make fracture section 91.
Like this, embedding forming section 90 does not need to use special engineering 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 base portion 10.And then, owing to when base portion 10 moulding, can embed stud bolt 26b, so can not increase manufacturing procedure, the manufacture cost of product is reduced.
In addition, by improving separately disposability, can reduce obsolescence cost.Just can improve and separate disposability owing to only at the embedding forming section 90 of base portion 10 (plastic article) fracture section 91 being set, so also can improve the degrees of freedom of design.
As mentioned above, the water supply device 1 according to present embodiment relates to arrange protuberance 34a and recess 58a as restriction section 29 in pump case 34 and inner casing 58, can prevent effectively common rotation under the state of manufacture cost keeping thus.In addition, utilize protuberance 34a and recess 58a can prevent the reduction of the pump efficiency of pump 13.
In addition, according to water supply device 1, by self-priming section 11 being divided into from the suction-chamber 36 and self-priming chamber cap 42, can be on base portion 10 one-body molded base body 20 and stream section 21.Thus, can reduce base portion 10 needed manufacturing procedures.
