Description
Technical field
This utility model is related to a kind of membrane pump.More particularly to a kind of membrane pump metal bellow type diaphragm and tool
There is the membrane pump of the diaphragm.
Background technology
Also known as controlling pump, it goes to change the flow of fluid by power operation membrane pump.Membrane pump has four kinds of materials：Modeling
Material, aluminium alloy, cast iron, rustless steel.Its diaphragm material is respectively adopted nitrile rubber, neoprene rubber according to different feed liquids
Glue, fluorubber, Kynoar, poly- four or six ethylene are meeting requirement.Special occasions is placed in, for pumping various conventional pumps not
Fluid foods can be aspirated.
As shown in figure 1, existing membrane pump is in pump case 10 to be divided into two symmetrical cavitys by dividing plate 15, each
Cavity is divided into an air drive chamber 2/4 and a liquid material room 1/3 by a diaphragm of diaphragm pump 13 again respectively, its
In, the symmetrical setting of air drive chamber 2/4 in two cavitys and positioned at the both sides of dividing plate 15, two liquid material rooms 1/3
It is the symmetrical side for arranging and being located remotely from dividing plate 15.Two diaphragm of diaphragm pump 13 being separately positioned in two spaces
Bottom surface 13a is connected by a diaphragm coupling spindle 19 through dividing plate 15, and the side 13b of two diaphragm of diaphragm pump 13 connects respectively
On described pump case 10.Wherein, Liang Ge air drive chamber 2/4 respectively connects reversal valve 9 by a trachea 7/8 respectively, described
The lower end of two liquid material rooms 1/3 respectively pass through respectively a feed tube 11/12 and to be separately positioned on the feed tube 11/
The two connection liquid of check valve 14 material inlets 5 on 12, the upper end of two described liquid material rooms 1/3 respectively passes through one respectively
Bar drain pipe 17/18 and the two connection liquid of check valve 16 material outlets 6 being separately positioned on the drain pipe 17/18.
Regulation and control of the membrane pump by reversal valve 9, promote barrier film by different compressions are carried out to the air in Liang Ge air drive chamber 2/4
Pump diaphragm 13 so as to change fluid flow, by feed tube 11/12 and goes out changing the pressure in two liquid material rooms 1/3
Liquid pipe 17/18 is pumping the liquid medium that various conventional pumps can not be aspirated.
Fig. 1, Fig. 2, Fig. 3 are three kinds of views of the membrane pump course of work of prior art, and Fig. 1 is in reversal valve 9
Regulation and control under 3 pumping liquid medium of liquid material room, 1 drain medium of liquid material room.Fig. 2 is the regulation and control in reversal valve 9
Medium is aspirated in lower steering liquid material room 1, and the pilot process of medium is discharged in liquid material room 3.Fig. 3 is the regulation and control in reversal valve 9
1 pumping liquid medium of lower liquid material room, 3 drain medium of liquid material room.Seen by Fig. 2：In coupling spindle 17 is located at
Between process scope position when because the side 13b of diaphragm of diaphragm pump 13 be in relaxed state, its shape is always one
Determine freely to change in scope, so necessarily make the volume of liquid material change therewith, therefore we cannot just use coupling spindle
Precise displacement go to realize the purpose of liquid with precise control mass flow come the volume that accurately adjusts liquid material.
The material of the septation pump diaphragm 13 of existing membrane pump is mostly nitrile rubber, neoprene, fluorubber, poly- inclined fluorine

Line position in-migration is realized, that is to say, that the variable quantity of the variable quantity of liquid material volume and the axial displacement of diaphragm bottom surface (coupling spindle)
Can follow without rule, even axially in static, but the volume of liquid material in size variation, the appearance of liquid material
No rule between product change and the action of diaphragm, so not only cannot directly observe the position of action, Er Qiewu with form
Method cloth displacement sensor carries out precise control, poor sensitivity.
4th, fixed mathematical function model cannot be set up, and liquid material is determined only by the experience of field adjustable and people
Output, therefore moment precise control can not possibly be accomplished, it is also not possible to accomplish that the ratio per a batch of product composition is complete
Overall height precision is consistent.Product quality and work efficiency are not only affected, the unnecessary waste of product and raw material is also resulted in.
5th, diaphragm is immersed in the medium of corrosivity, swellability extremely easy bulk and comes off, and blocking pipeline causes behaviour by mistake
Make.
6th, deformation range is little, and the Volume variation scope in each cycle is little, so frequency of vibration is high.
