Accompanying drawing explanation
Fig. 1 is the structural representation of the electric diaphragm pump that one embodiment of the invention provides.
Detailed description of the invention
Hereinafter, the present invention is further elaborated in conjunction with the accompanying drawings and embodiments.
As it is shown in figure 1, electric diaphragm pump provided by the present invention includes: eccentric parts, slider part, spring members,
Power transmission shaft parts, webbing members.Eccentric parts are the part of input torque, including bearing 5 and eccentric shaft 6, described bearing 5
All it is connected with reducing motor axle with eccentric 6, reducing motor axle transmission moment of torsion.Slider part includes slide block 4；Bearing 5 is with eccentric
Wheel 6 is arranged in slide block 4, and bearing 5 outer surface is tangent with inner surface.The axis of guide 2 and power transmission shaft 3 pass in the hole of slide block 4, guide
Slide block 4, simultaneously also through in centrosome 1, is fixed in centrosome 1 by axle 2 and power transmission shaft 3.Spring members mainly has gas bullet
Spring 7 and spring support 8.Air spring 7 links together with screw with spring support 8, and is contained on power transmission shaft 3.Power transmission shaft parts
Mainly having power transmission shaft 3 and axle sleeve 9, axle sleeve 9 is enclosed within power transmission shaft 3 two ends.Webbing members mainly has right outer plate 10, right diaphragm 11 He
Right clip plate 12；Left outside pressing plate, left diaphragm and left inside pressing plate.Right outer plate 10, right clip plate 12 are respectively from two relative tables
Fitting with right diaphragm 11 in face, and surrounds right cavity on the right side of the pump housing 13；Left outside pressing plate, left inside pressing plate are respectively from two relative tables
Fitting with left diaphragm in face, and surrounds left cavity on the left of the pump housing 13.Outer plate, diaphragm and clip plate pass through screw and power transmission shaft
Compression is integrated.
Normal work process is: bearing 5 is arranged on eccentric shaft 6, when eccentric shaft 6 is in the drive of reducing motor reduction box
The when of lower rotation, bearing 5 rotates within the scope of eccentric throw, and the circumference of bearing 5 is close to slide block 4, slide block 4
Center has power transmission shaft 3 to pass, and power transmission shaft 3 is arranged on the centrosome 1 of centre bore, and therefore the motion of slide block is limited by axle
Cannot move in a circle, slide block 4, under the guiding of power transmission shaft 3, can only do the reciprocating motion of left and right.When bearing 5 moves right
Time, slide block 4 is promoted air spring 7, and is delivered on axle sleeve 9 by 8 thrusts of spring support, and axle sleeve 9 has promoted right outer plate
10, right diaphragm 11 and right clip plate 12.Right diaphragm 11 moves right, then make the cavity on the right of membrane pump start output liquid.By
Being screwed on power transmission shaft 3 in right inside and outside pressing plate, therefore inner-outer pressing plate has driven power transmission shaft 3 to move right together.Due to
Moving right of power transmission shaft 3, has driven the inner-outer pressing plate 10,12 on the left side and diaphragm 11 to left movement, has then made the membrane pump left side
Cavity starts pumping liquid.When bearing 5 to left movement when, slide block 4 has promoted left side air spring, in like manner above step, every
The left side cavity of membrane pump starts output liquid, and the cavity on the right starts pumping liquid.Therefore bearing 5 promotes about sliding shoe 4 work
Move back and forth.The diaphragm 11 of membrane pump moves reciprocatingly together along with axle, completes suction and the output procedure of membrane pump.
With continued reference to Fig. 1, when the valve in pipeline is closed or turned down, and the back pressure in pipeline increases suddenly or slowly
Added-time, when the pressure from pump housing arrives or exceedes certain numerical value, such as during 4bar, i.e. act on external pressure on the right of diagram
Pressure on plate 10 exceedes the normal value of setting, and slide block continues to want by air spring 7 and spring air spring support 8, and passes through axle
Set 9 is delivered to inside and outside pressing plate, but the counteracting force suffered by inside and outside pressing plate is delivered on air spring 7 with identical numerical value.
When this power exceedes the initial pressure value of air spring when, the stroke lever of air spring compresses, at this time slide block 4 continue to
Right motion, but owing to the stroke of air spring there occurs compression, because there is the fortune of relative slip between slide block with power transmission shaft 3
Dynamic, at this time there occurs the motion being commonly called as skidding.That is slide block is in motion, but the power acted on is not delivered to external pressure
On plate.This process is a process being gradually increased, because the compression stress of air spring can be continuous along with the increase of compression travel
Increasing, the active force of outer plate continues to increase, until reaching the termination pressure of air spring.Two power have reached balance, this
Sample slide block is just thoroughly carrying out slip/stick movement, and diaphragm will not continue to move, and the liquid inside pump chamber is not the most further added by pressure
Power.Now diaphragm no longer moves back and forth, and the fluid inside the pump housing just stopped conveying, so serve the protection pump housing from
The effect of back pressure.
With continued reference to Fig. 1, when the valve of cavity is opened when, the pressure of the pump housing is discharged, inner-outer pressing plate 10,11
Pressure experienced gradually decreases, and during the numerical value of the initial forces being reduced to air spring 7, air spring 7 acts on spring fastening 8
Power continued to press on axle sleeve 9 and inner-outer pressing plate.Making diaphragm 11 re-start work, liquid has recovered conveying, sends out for described
The electric diaphragm pump that bright embodiment provides has the function automatically resumed work.
With continued reference to Fig. 1, between usual slide block 4 and power transmission shaft 3, do not carry out the fixing, in order to anti-limited slip block is past of radial direction
During multiple motion, there is flip-flop movement, be provided with second axis of guide 2.The axis of guide 2 is possible to prevent due in fortuitous event
Slide block overturns, and then with other moving components, the phenomenon of friction occurs.
