Description
Technical field
It the utility model is related to a kind of membrane pump, more particularly to a kind of electric diaphragm pump.
Background technology
Membrane pump is to change swept volume of a single chamber by agitating back and forth for diaphragm so as to suck and discharge liquid.Its
In, electric diaphragm pump is to promote the barrier film on corresponding pump chamber to move back and forth by the push rod of motor driven the right and left,
So that the motion of the non-return valve barrier film of total of four up and down in the pump chamber of left and right two, so as to cause changing for the volume in pump chamber
Become, force four non-return valves alternately to open and close, so as to which liquid to be continuously drawn into and discharge.
Existing electric diaphragm pump is one eccentric part of setting on motor（Such as crank, eccentric shaft, cam etc.）, lead to
Eccentric part is crossed with promoting the push rod of barrier film to be hinged, push rod is back and forth promoted corresponding pump chamber in the presence of eccentric part
Barrier film.But when barrier film is back and forth promoted, if be hinged tension easily causes push rod sensitivity low, and eccentric part
Be hinged with push rod easily loosens as membrane pump works for a long time so that push rod precision reduces.In addition, to barrier film
When pump is safeguarded, the installing/dismounting of eccentric part and push rod is cumbersome, increases the workload of plant maintenance.
The content of the invention
Problem to be solved in the utility model is to provide a kind of electric diaphragm pump, this electric diaphragm pump is simple in construction,
Installing/dismounting is more prone to, and has higher accuracy and sensitivity.The technical scheme of use is as follows：
A kind of electric diaphragm pump, including the pump housing, the pump housing are provided with liquid inlet, liquid outlet and two symmetrical pumps
Chamber, liquid inlet, liquid outlet are connected with two pump chambers；Form drive chamber between two pump chambers, drive chamber with two
A pair of relative barrier films are provided between pump chamber, are used to promote barrier film reciprocating provided with motor, cam and two in drive chamber
Push rod, cam fix peace turn on the output shaft of motor, one end of push rod is connected with corresponding barrier film, it is characterised in that：
Also include upper rail, lower guideway, two pieces of push pedals and connector；Upper rail, lower guideway are arranged in the drive chamber one on the other,
Two pieces of push pedals are installed in upper rail, can move on lower guideway and along upper rail, lower guideway；Two pieces of push pedals are connected by connector
It is connected together；The cam is between two pieces of push pedals, and madial wall of the cam always with one of push pedal is engaged；
Lateral wall of two push rods respectively with corresponding push pedal is fixedly connected.
Above-mentioned connector is mainly used in making in the course of work of whole electric diaphragm pump the position of two pieces of push pedals to keep relative
It is constant, connection strap, connecting plate etc. can be set on the relative side of two pieces of push pedals, one can also be used together with two pieces of push pedals
One framework of body formed formation.
The output shaft driving cam of motor rotates, and makes two pieces of constant push pedals of relative position holding along upper and lower rails or so
It is mobile, so as to drive push rod to promote the barrier film on corresponding pump chamber to move back and forth；Because cam is in rotation process, always
It is engaged with the madial wall of one of push pedal, promotes the push pedal to be moved to corresponding direction, makes the barrier film extrusion pump of the side
Chamber and volume diminishes, ball valve in the side pump chamber is opened, and the barrier film of relative opposite side loosens the pump chamber for making opposite side
Become big, the ball valve in opposite side pump chamber is closed.
The utility model compared with prior art, has the following advantages that：
The utility model electric diaphragm pump promotes the type of drive of two pieces of constant push pedals of relative position holding using cam
Realize that two push rods move back and forth, so as to promote barrier film to change the volume size of two pump chambers, due between cam and push pedal
Simply it is engaged, not actual annexation, structure is simpler, and installs, dismantles and maintenance is more prone to,
And it is rolling friction between cam and push pedal during cam rotation forces push pedal, there is higher precision and sensitive
Degree, controllability are more preferable；In addition, two pieces of push pedals move along upper and lower rails, stability is higher when the push rod is promoted barrier film.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Embodiment
It is described further below in conjunction with the accompanying drawings with preferred embodiment of the present utility model.
As shown in figure 1, a kind of electric diaphragm pump, including the pump housing 1, the pump housing are provided with liquid inlet 101, liquid outlet 102
With two symmetrical pump chambers 103, liquid inlet 101, liquid outlet 102 are connected with two pump chambers 103, two pumps
Drive chamber 2 is formed between chamber 103；Relative a pair of barrier films 3 are provided between drive chamber 2 and two pump chambers 103, are set in drive chamber 2
There is motor（Do not indicated in figure）, 4, two, cam is used to promote barrier film 3 reciprocating push rod 5, two pieces of push pedals 6, connectors
7th, upper rail 8 and lower guideway 9；Upper rail 8, lower guideway 9 are arranged in drive chamber 2 one on the other；Two pieces of push pedals 6 are installed in
It can move on guide rail 8, lower guideway 9 and along upper rail 8, lower guideway 9, two pieces of push pedals 6 to be formed with connector 7 using being integrally formed
One framework；Cam 4 is fixed peace and turned on the output shaft 401 of motor between two pieces of push pedals 6, and cam 4 always with its
In the madial wall of one piece of push pedal 6 be engaged；One end of push rod 5 is connected with corresponding barrier film 3, the other end and the phase of push rod 5
The lateral wall for the push pedal 6 answered is fixedly connected.
The driving cam 4 of output shaft 401 of motor rotates, and makes two pieces of constant push pedals 6 of relative position holding along the He of upper rail 8
Lower guideway 9 moves left and right, so as to drive push rod 5 to promote the barrier film 3 on corresponding pump chamber 103 to move back and forth；Due to cam 4
In rotation process, always the madial wall with one of push pedal 6 is engaged, and promotes the push pedal 6 to be moved to corresponding direction,
Make the side barrier film 3 extrude pump chamber 103 and volume diminishes, the ball valve 104 in the side pump chamber 103 is opened, and relative opposite side
Barrier film 3 loosen and the volume of pump chamber 103 of opposite side is become big, the ball valve 104 in opposite side pump chamber 103 is closed.
Due to being simply engaged between cam 4 and push pedal 6, not actual annexation, structure is simpler,
And install, dismantle and maintenance is more prone to, and during the rotation forces push pedal 6 of cam 4, between cam 4 and push pedal 6
It is rolling friction, there is higher accuracy and sensitivity, controllability is more preferable；In addition, two pieces of push pedals 6 are along upper rail 8 and lower guideway 9
Move, make push rod 5 promote barrier film 3 when stability it is higher.
Furthermore, it is necessary to illustrate, the specific embodiment, its each several part title etc. described in this specification can not
Together, the equivalent or simple change that all construction, feature and the principle described according to the utility model patent design are done, is included in this
In the protection domain of utility model patent.The utility model person of ordinary skill in the field can be to described specific reality
Example is applied to make various modifications or supplement or substitute using similar mode, without departing from structure of the present utility model or
Surmount scope defined in the claims, the scope of protection of the utility model all should be belonged to.
