Description
Technical field
The present invention relates to such as towards the Eletromagnetic diaphragm pump of fuel gas force feed of the Eletromagnetic diaphragm pump of housekeeping fuel cell, LPG etc., particularly a kind of Eletromagnetic diaphragm pump, possess this liquid spilt in the case of fluid spills due to damaged grade of barrier film inside pump and can not enter the isolation structure at the energising position that electric current is crossed, the buffer action of this isolation structure can be given the most in advance and prevent from leaking the generation of the accident etc. caused in advance, and electromagnetic type pump performance can be suppressed to reduce.
Background technology
In the past, known a kind of Eletromagnetic diaphragm pump, as shown in the diagrammatic top profile of Fig. 6, make oscillator 510 vibrate along the above-below direction of drawing by electromagnet 500, make barrier film 520 conjugate, the fluid becoming moving object sucks and spues (discharge).
In such Eletromagnetic diaphragm pump, generally, the both ends at oscillator 510 are configured with the barrier film 520 of opposite a pair.Further, the side at oscillator 510 is configured with the electromagnet 500 of a pair when separating predetermined distance along the side of oscillator 510.Further, not shown alternating current power supply is connected with the electromagnet coil of electromagnet 500, produces the change (change in polarity) of the magnetic pole of the number of times identical with the frequency of alternating current power supply.Thus, being configured to the change in polarity along with the electromagnet 500 being connected with alternating current power supply, oscillator 510 moves back and forth with the frequency identical with alternating current power supply.
Reciprocating motion with such oscillator 510 synchronously, is arranged in the barrier film 520 at both ends of oscillator 510 centered by the central part of this barrier film, with the addendum modification deformation identical with the stroke of oscillator 510.Thus, produce the change of capacity of chamber of septum 530, via as the inlet valve 535 of check valve and discharge valve 536, carry out the suction of fluid and the operation that spues, the most pump operated.
In such Eletromagnetic diaphragm pump, in the case of object conveyor is imflammable gas, for example, it is desired to this imflammable gas is fully separated from the electromagnet 500 etc. with the position that electric current flows through.Therefore, in the example shown in Fig. 6, select following structure: in order to isolate electromagnet 500 and oscillator 510, the separation cylindrical portion 550 surrounding oscillator 510 is made as die-cast part, even if in the case of contingency imflammable gas spills inside pump because of the breakage of barrier film 520 grade, the imflammable gas of leakage also will not be from the inside 550a of the separation cylindrical portion 550 of encirclement oscillator 510 to connecting electromagnet 500 side inflow that have alternating current power supply.

Further, in order to be formed for configuring the space of electromagnet 500 in the outside separating cylindrical portion 550, for being arranged in the core components (not shown) of this part, it is also desirable to along the draft of paper inboard region direction of the drawing of outer lines H separating cylindrical portion 550.
Owing to arranging draft 600 at the inner surface separating cylindrical portion 550 in this wise and arranging draft along the paper inboard region direction of outer lines H separating cylindrical portion 550, separate in cylindrical portion 550, the Thickness Distribution in the face facing with the surface of opposite the electromagnet 500 configured is not certain, there is the thick part of thickness and thin part, further, line H is produced to paper inboard region direction.Due to these reasons, it is impossible to make narrow with the gap of electromagnet 500, therefore produce because between electromagnet, slit width and performance reduce, i.e. can not increase by bad to the power that oscillator 510 applies of electromagnet 500.And, because of draft 600, Thickness Distribution is not necessarily located, as far as possible with thin-walled corresponding time, the core of the so-called foundry goods that the generation of generation bubble etc. causes, in the case, sometimes produce intercommunicating pore partly in the wall portion separating cylindrical portion 550, there is imflammable gas and flow into the possibility of electromagnet 500 side.
Further, when separating the shaping of cylindrical portion 550, when internal involutory surface (at line G) produces burr, deburring operation afterwards needs a lot of man-hours.
As different from the problem of the application but be considered to have the prior art of the structure similar with the application, there is Japanese Unexamined Patent Publication 2006-169988 publication.
Invention in the Japanese Unexamined Patent Publication 2006-169988 publication quoted proposes to solve following problems, the heat i.e. flowing through electric current in the coil windings portion of electromagnet and produce via oscillator or is transferred directly to barrier film, barrier film is heated, barrier film exposes at high temperature heat ageing, thus can not realize long lifetime.This invention selects the structure of exterior arrangement electromagnetism body (50) in the inside of housing (20) configuration mover (30) and barrier film (40) at housing (20).Therefore, the mover incorporating section (21) of housing (20) becomes partition wall, and the heat energy that will be produced by electromagnet (50) cuts off, it is possible to prevent barrier film (40) heated and aging, it is possible to realize the long lifetime of barrier film (40).

<explanation of the pith structure in the present invention>
In the present invention, in the way of covering oscillator 30 with separating certain interval, transducer cover 100 it is provided with as described above.The deformation rectangle making rectangular angle be fillet that the shape in the cross section vertical with long side direction of transducer cover 100 such as becomes as shown in Figure 3 is ring-type, but it is not limited to this shape, can be according to the cross sectional shape of oscillator, suitably select in the mode etc. of electromagnet of both sides configuration.In the present invention, such transducer cover 100 is made up of the parts with barrier film platform 50 split.In the present invention, whether whether split is not made up of identical material with transducer cover 100 and barrier film platform 50 and is judged, and be previously separated with the parts of both sides and judge.Integrally formed product are not the structures of split.
As it has been described above, by the barrier film 40 of the barrier film platform 50 of a pair and a pair, in the position than barrier film 40, position in the inner part forms the inner compartment 165 of a pair, in the way of making the connection of this inner compartment of a pair 165, installs the transducer cover 100 (with reference to 2) in the present invention.At the both ends of transducer cover 100, such as fix with barrier film platform 50 via transducer cover liner 155 in the bubble-tight mode remaining engaged with place to the barrier film platform 50 of the most opposite a pair.
The barrier film platform 50 engaged with transducer cover 100 in this wise has: clamping base portion 51, has the effect of the circumference of clamping barrier film 40；Peristome 53, makes the end portion of oscillator 30 pass through；And incorporating section, it is formed at the peripheral part of this peristome 53, the end of transducer cover 100 is received together with transducer cover liner 155.
Such incorporating section is configured to have: liner mounting surface 53a, and the peripheral part at peristome 53 is formed and loads transducer cover liner as shown in figures 2 and 5；And shaft of rib 55a, the peripheral part in this liner mounting surface 53a highlights, and becomes the parts of guiding/setting-in when the end making transducer cover 100 is inserted.Shaft of rib 55a can be made up of the continuous print protuberance of closed loop, but as in the present invention preferred embodiment, be configured to that there is a cut-away 55b part for the protuberance of closed loop cut.Transducer cover liner 155 is formed accordingly with the structure of such shaft of rib 55a.I.e., as it is shown in figure 5, the inner side being arranged on shaft of rib 55a substantially and the transducer cover liner 155 that is positioned in the liner mounting surface 53a sealing 155a that possesses the closed loop of the inner side being accommodated in shaft of rib 55a and the jut 155b that is protrudedly formed outward in the position of the substantially central portion of this sealing 155a.Further, this jut 155b is configured to be inlaid in cut-away 55b in the gap becoming shaft of rib 55a.
Embodiments of the present invention, owing to having such special cut-away 55b and the mode of jut 155b, therefore represent the cross section cutting position at the line A-A in Fig. 4 C and line B-B two with the top view of Fig. 4 A and Fig. 4 B.In Fig. 4 A, it is to there is not the profile at cut-away 55b of shaft of rib 55a, therefore in the position that the end of transducer cover 100 abuts with barrier film platform 50 via transducer cover liner 155, does not exists as the shaft of rib 55a in the cross section represented with hatching.Further, the transducer cover liner 155 in the position of Fig. 4 A is to exist at jut 155b, and the cross-sectional width of this liner is wide cut (comparing with Fig. 4 B) the most as shown in the figure.On the other hand, Fig. 4 B is to there is the profile that (there is not the position of cut-away 55b) at shaft of rib 55a, therefore there is the shaft of rib 55a as the cross section represented with hatching.Further, there is not jut 155b in the transducer cover liner 155 of this position, the cross-sectional width of this liner is bandpass the most narrow (comparing with Fig. 4 A) the most as shown in the figure.
Further, the transducer cover 100 in the present invention is preferably configured as, and in the face of side opposite with electromagnet, homogeneity and the flatness of wall thickness is good especially.I.e., as depicted in figs. 3 and 5, in the case of transducer cover 100 is seen in the cross section vertical with long side direction, it it is the tectosome (substantially cylindrical body) being integrally connected, possessing the side panel portion 101 of a pair configured oppositely with electromagnet and link the web portion 102 in these side panel portions 101, side panel portion 101 is configured to have homogeneous wall thickness.Homogeneous wall thickness described in the present invention refers to recognize the uniform level of the degree of the existence of the draft (pattern draft) under conventional meaning.
By possessing the precision of such wall thickness, it is possible to form the side panel portion 101 of homogeneous thin-walled, it is possible to prevent electromagnetic type pump performance from reducing.
The transducer cover 100 of the tubular with the most homogeneous wall thickness can be formed by stretch process.So-called stretch process, be not heating raw materials and at room temperature raw material is stretched by the narrower bore of mould thus the method processed.Stretching raw material typically more uses extrded material, but nor is it necessary that the matrix making extrded material become the initial stage.
And, it is also possible to replace stretch process and form transducer cover 100 with extrusion process.Extrusion process is by aluminum or aluminum alloy method of extruding under the heating of such as 400 ~ 500 DEG C.Usually, use extruder to apply strong pressure, the metal derby (metal base) of cylinder is squeezed out from having variously-shaped die hole, forms elongated extrded material.
Additionally, transducer cover 100 is made up of nonmagnetic substances such as aluminum or aluminum alloy.Further, the explanation of the structure of Eletromagnetic diaphragm pump is carried out.
As in figure 2 it is shown, be formed with the side opening oral area 15(in body frame 10 with reference to Fig. 1) in the recess of barrier film maintaining part 60 that is fixedly mounted with and the jacket 85 that formed via shell liner 80 and the induction chamber 150 that marks off.This induction chamber 150 links mouth 18 via not shown communication path with input and connects.With roughly the same method, as in figure 2 it is shown, be formed with the side opening oral area 15(in body frame 10 with reference to Fig. 1) in the barrier film maintaining part 60 that is fixedly mounted with and the jacket 85 that formed via shell liner 80 and the discharge room 170 that marks off.This discharge room 170 links mouth 19 via not shown communication path with output and connects.Additionally, induction chamber 150 and discharge room 170 are by partition wall 69 zoning.
On the partition wall 61 of barrier film maintaining part 60 dividing induction chamber 150, inlet valve 120 as depicted is installed from inner side.Inlet valve 120 is configured to possess the circular valve head 121 of the thin-walled worked as sealing valve and fixes axle 125 from the valve that the central part of this valve head 121 is prominent.Valve is fixed axle 125 and is installed/be fixed on the fixing hole (Fig. 2) being formed on partition wall 61.Although it is not shown, but fix the point of axle 125 at valve, it is often desirable that form the fastener of the overshooting shape prevented that comes off after fixing.Additionally, the plane that the be positioned at side of axle 125 fixed by the valve of valve head 121 constitutes so-called (valve) sealing plane.
By the valve action of such inlet valve 120, as in figure 2 it is shown, by the valve passage 62 being formed at partition wall 61, the fluid linking mouth 18 inflow from input is inhaled into chamber of septum 160.Chamber of septum 160 is carried out zoning by the face (particularly partition wall 61) of barrier film 40 and the inside of barrier film maintaining part 60 substantially.And, it is inhaled into the fluid valve action by the discharge valve 130 of the partition wall 61 being installed on barrier film maintaining part 60 from outside of chamber of septum 160, by being formed at the valve passage 63 of partition wall 61, enter discharge room 170, link mouth 19 via not shown communication path from output and spue.
The mode of discharge valve 130 itself is essentially identical with above-mentioned inlet valve 120, and its structure is configured to, as in figure 2 it is shown, possess as sealing the valve head 131 of the thin-walled circle that valve works and fixing axle 135 from the valve that the central part of this valve head 131 is prominent.Valve is fixed axle 135 and is installed/be fixed on the fixing hole (Fig. 2) being formed at partition wall 61.The point of axle 135 is fixed, it is often desirable that form the fastener of the overshooting shape prevented that comes off after fixing at valve.Additionally, the plane that the be positioned at side of axle 135 fixed by the valve of valve head 131 constitutes so-called (valve) sealing plane.
Further illustrate inlet valve 120 and the valve action of discharge valve 130.Along with the change in polarity of the electromagnet 20 being connected with alternating current power supply, oscillator 30 is with the frequency identical with alternating current power supply, along arrow (α) as shown in Figure 2 and the reciprocating motion of arrow (β) direction.With the synchronized movement ground of this oscillator 30, the barrier film 40 at the both ends being arranged in oscillator 30 deforms with the addendum modification identical with the stroke of oscillator 30 centered by the central part of this barrier film 40.Thus, the capacity of chamber of septum 160 changes, if being conceived to the chamber of septum 160 of (β) side, direction of Fig. 2, then at barrier film 40 in the case of arrow (α) Direction distortion, chamber of septum 160 expands and becomes negative pressure, and inlet valve 120 is opened, and fluid is inhaled in chamber of septum 160.On the contrary, at barrier film 40 in the case of arrow (β) Direction distortion, the chamber of septum 160 of (β) side, direction is compressed and is become malleation, and discharge valve 130 is opened, and fluid spues to discharge room 170 in chamber of septum 160.Alternatively being carried out continuously these actions, fluid is spued continuously.
And, in the present invention, even if just in case inner compartment 165(within fluid (such as imflammable gas) inflow pump is with reference to Fig. 2 because of the breakage of barrier film 40 grade), owing to the inner compartment 165 of a pair is connected under keeping bubble-tight state by transducer cover 100, so fluid cannot flow into connects the electromagnetism side having power supply.
Furthermore, it is possible to suitably set the concrete mode of the inlet valve 120 used in the present invention and discharge valve 130 according to the specification of Eletromagnetic diaphragm pump, such as valve head 121(131) the size of external diameter or thickness etc..Further, for the inlet valve 120 used and discharge valve 130 number too.The quality of rubber materials constituting inlet valve 120 and discharge valve 130 is not particularly limited.Such as, EPDM or silicone rubber can be included as suitable example.
Further, the quality of rubber materials constituting barrier film 40 is not particularly limited, but thermostability and excellent corrosion resistance can be included as suitable example, fluorubber that pliability is the most excellent, NBR.
Further, as supplementary notes, in FIG, symbol 201 representational framework liner; symbol 202 representational framework cover, symbol 211 represents that case liner, symbol 212 represent case cover; symbol 220 represents that vibration-proof rubber, symbol 230 represent bracket, and symbol 241,245 represents barrier film screening glass.
