Though the design of double diaphragm pump is arranged at present, and its power source mostly is located at the centre of two pump chambers, this power source is based on pneumatic, and like this, it is complicated that its overall structure becomes, and causes cost up; Moreover the Placement of its pulling diaphragm displacement running also makes diaphragm damaged by this place, and then reduces working life.
So existing diaphragm pump still has the space of improvement.
The model utility content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that existing product exists, and a kind of diaphragm pump is provided, and it has application scalability preferably, and has the effect of being convenient to expanded application in parallel.
Another purpose of the present utility model is to provide a kind of diaphragm pump, be to adopt motor as the major impetus source, two pump chambers are in the other direction also by the all-in-one-piece structure, motor as power source is located at a wherein side, drive two driveshaft shift reciprocatelies by an interlock body again, two driveshafts and two diaphragm ways of connecting be the clamping wheel (sheet) that utilizes two peripheries to be circular arc be clipped in diaphragm in, the outside, and then by two clampings wheels (sheet) drive diaphragm displacement, avoid injuring diaphragm, increase its working life, effectively overcome existing double diaphragm pump and pneumatic element has been located at the defective that constitutes in the middle of two pump chambers.
A purpose more of the present utility model is to provide a kind of diaphragm pump, its base structure simplicity of designization, and kind of drive excellent in efficiency, and the reduction of whole cost meet industry demand.
The purpose of this utility model is realized by following technological scheme.
The utility model diaphragm pump is characterized in that, comprising: a pedestal, form two pump chambers with open surface, and two pump chambers are connected with pump intake and pump discharge respectively, and pump intake is provided with the inlet check valve, and pump discharge is provided with the outlet check valve; Two diaphragms suppress its periphery by two lockings at the ring segment of pedestal, and cover cover the open surface that is positioned at two pump chambers; Two driveshafts, the inner diaphragm that clamps correspondence respectively by two holding sheets; One interlock body connects the outer end of two driveshafts, and other is connected with the reciprocating power member.
Aforesaid diaphragm pump, wherein the interlock body is made of two two connecting rods that wear bar and connect for two driveshaft outer ends that are located in pedestal.
Aforesaid diaphragm pump, wherein the reciprocating power member is that motor, speed reducer and crank constitute.
Aforesaid diaphragm pump, wherein the reciprocating power member is a pneumatic cylinder.
The beneficial effect of the utility model diaphragm pump, it comprises: a pedestal is to form two pump chambers with open surface, and two pump chambers are connected with pump intake and pump discharge respectively, and are provided with the inlet check valve at pump intake, and are provided with the outlet check valve at pump discharge; Two diaphragms suppress its periphery by two lockings at the ring segment of pedestal, and cover cover the open surface that is positioned at two pump chambers; Two driveshafts, inner two holding sheets that utilize respectively clamp corresponding diaphragm; One interlock body wears bar by two and is located in pedestal, and two connecting rods that connect for two driveshaft outer ends constitute, and other is connected with the reciprocating power member.The utility model only need dispose a power in the defeated point of delivery of single pressurization, as long as and make adjacent interlock body 40 constitute annexation, just can directly in parallelly use, have the effect of being convenient to expanded application in parallel.

Major label description in figure: 10 pedestals, the 11a pump chamber, the 11b pump chamber, the 12a pump intake, the 12b pump intake, the 13a pump discharge, the 13b pump discharge, the 14a check valve that enters the mouth, the 14b check valve that enters the mouth, 15a exports check valve, 15b exports check valve, the 20a diaphragm, the 20b diaphragm, the 21a ring segment, the 21b ring segment, the 30a driveshaft, the 30b driveshaft, the 31a holding sheet, the 31b holding sheet, the 31c holding sheet, the 31d holding sheet, 40 interlock bodies, 41a wears bar, 41b wears bar, the 42a connecting rod, the 42b connecting rod, 50 reciprocating power members, 51 motors, 52 speed reducers, 53 cranks.
Embodiment
Consult Fig. 1 to shown in Figure 3, the utility model diaphragm pump comprises, one pedestal 10, it is formed with two pump chamber 11a, the 11b of open surface, two pump chamber 11a and 11b are connected with pump intake 12a, 12b and pump discharge 13a, 13b respectively, and be provided with inlet check valve 14a, 14b at pump intake 12a, 12b, and be provided with outlet check valve 15a, 15b at pump discharge 13a, 13b;
Two diaphragm 20a, 20b suppress its periphery by two lockings at ring segment 21a, the 21b of pedestal 10, and cover cover the open surface that is positioned at two pump chamber 11a, 11b; Two driveshaft 30a, 30b, inner diaphragm 20a, the 20b that clamps correspondence respectively by two holding sheet 31a, 31b and 31c, 31d;
One interlock body 40 two wears bar 41a, 41b by what be located in pedestal 10, and the two connecting rod 42a, the 42b that connect for two driveshaft 30a, 30b outer end constitute, and other is connected with reciprocating power member 50; Wherein, this reciprocating power member 50, embodiment shown in the figure is that motor 51, speed reducer 52 and crank 53 constitute, and the pneumatic cylinder that has the reciprocating action effect equally also may be utilized.
Constitute based on as above structure, when reciprocating power member 50 makes interlock body 40 produce to-and-fro motion, also to-and-fro motion thereupon of two driveshaft 30a, 30b, but because of two driveshaft 30a, 30b the installing direction opposite, so, present an into phenomenon of moving back, cause two diaphragm 20a, 20b one outer opening in one to be contracted, form the effect of pressurized delivered fluid at two pump chamber 11a, the 11b of pedestal 10 thereby continue.
Moreover, if have when the big feed flow demand, then can several comprise the agent structure of pedestal 10, two diaphragm 20a and 20b, two driveshaft 30a and 30b and interlock body 40 side by side, and make adjacent interlock body 40 constitute annexation, but only provide required power by a reciprocating power member 50.So the utility model only needs power of configuration at single pressurized delivered point, as long as and make adjacent interlock body 40 constitute annexation, just can directly in parallelly use, have the effect of being convenient to expanded application in parallel.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
