Description
Technical field
The invention belongs to hydraulic diaphragm pump technical fields, are related to diaphragm, especially a kind of high-intensitive reciprocating hydraulic diaphragm
Pump uses diaphragm.
Background technique
Hydraulic diaphragm pump due to it is high, high-efficient with pressure, save the energy, without leakage, no pollution, the long-life, highly reliable
The features such as, it is widely used in various inflammable, explosive, toxicity, the corruption of the industries such as petroleum, chemical industry, food, medicine, electric power, water process
The quantitative conveying of the media such as corrosion or non-aggressive.Hydraulic diaphragm pump is (oily by pumped (conveying) medium and driving medium using diaphragm of rubber
Class) it separates, the oil medium transmitting that reciprocates through of piston acts on diaphragm of rubber, makes diaphragm of rubber deformation of unevenness, completes material
The sucking and discharge of slurry.This work for pumping the granule medium and pump that not only make pumped (conveying) medium more importantly make conveying without that leaks
Plug moving component does not contact, and eliminates solid particle and is seriously worn caused by pump, to keep the stability of pump and reliability big
Amplitude improves.Currently, common diaphragm of rubber shape is round flat sheet membrane, wherein plunger, round flat sheet membrane, in reality
In use process, round flat sheet membrane outer circumferential edge is fixed, front and back deflection deformation on the inside of diaphragm, front and back deflection deformation size and deformation
Stress intensity is related, and deflection deformation is excessive, and stress caused by diaphragm is also larger, and the stress of round flat sheet membrane is in diaphragm edge
Reach maximum value with circular central, therefore the stress of diaphragm is easy to produce concentration and is also easy to produce dramatically changing for stress, thus
So that the service life of diaphragm is shorter.Cause consumptive material more in addition, round flat sheet membrane radial dimension is excessive, nothing on round flat sheet membrane
Slot position is installed, installation maintenance is inconvenient.
By the retrieval of patent document, such as next chapter pertinent literature is only found:
Annular U type diaphragm for hydraulic diaphragm pump (CN201206542), the side wall of the annular U type diaphragm encompass for
Hollow structure, the middle part indent of annular sidewall, both ends expand outwardly into horn-like, and the bell-mouthed outer rim liquid of one end is hermetically pacified
In the diaphragm cavity wall of hydraulic diaphragm pump, the bell-mouthed outer rim of the other end and the diaphragm cavity wall have spacing, described
The diaphragm plate of liquid sealing cooperation therewith is installed, the diaphragm plate is matched with the annular U type diaphragm on the horn mouth of the other end
Close, by the diaphragm cavity of hydraulic diaphragm pump be separated into positioned at the inside of annular sidewall and diaphragm plate oil pocket and be located at annular sidewall and
The dielectric cavity of the outside of diaphragm plate.
By the comparison of technical characteristic, patent document disclosed above uses the U-shaped diaphragm of symmetric annular, middle part indent, both ends
Expand outwardly into it is horn-like so that all pressure spots are focused at the closing waist in the middle part of diaphragm when compressive deformation, and due to
Its deformation range is excessive, not only influences the content of sucking medium, the technology knot with the two-sided absorption wall-attaching type diaphragm patent of the present invention
Structure is not identical, will not influence the creativeness and novelty of the present patent application.
Summary of the invention
It is an object of the invention to provide in place of overcome the deficiencies in the prior art, a kind of structure is simple, simple installation, radial direction
Size reduces, consumptive material is few, stress is not easy to concentrate, the high-intensitive reciprocating hydraulic diaphragm pump with long service life of diaphragm with every
Film.
The present invention solves its technical problem and adopts the following technical solutions to achieve:
A kind of high intensity reciprocating hydraulic diaphragm pump diaphragm, including fixed ring and two way seal diaphragm, the fixation
The inside ring wall of ring, which coaxially vulcanizes, two way seal diaphragm, the two way seal diaphragm include tensioner ring film, veneer sealing film with
And reinforcing ring film, tensioner ring film section are arc, the arcuate lower surface of tensioner ring film, which is uniformly spaced, to be formed with multiple arcs and adds
Strong item is radially-inwardly formed with veneer sealing film at the inner sidewall of the tensioner ring film, in tensioner ring film and veneer sealing film rank
The veneer sealing film upper surface at the place of connecing also integrally is formed with a reinforcing ring film.
Moreover, the root of the reinforcing ring film and the root of veneer sealing film cover the form for forming duplicature together.
Moreover, being also formed with installation slot position in the fixed ring.
Moreover, the material of the two way seal diaphragm is polyurethane.
Moreover, the material of the fixed ring is polyformaldehyde.
The advantages and positive effects of the present invention are:
1, the present invention is uniformly spaced in the inner surface of arc tensioner ring film and is formed with arc stiffener, considerably increases tensioner ring
The expansion deformability of film, so that stress is not easy to concentrate, to improve the recovery capacity of diaphragm, extend diaphragm uses the longevity
Life.
2, the present invention is radially-inwardly formed with veneer sealing film at the inner sidewall of tensioner ring film, and in tensioner ring film and patch
The veneer sealing film upper surface of face sealing film joining place is also integrally formed with a reinforcing ring film, the root of the reinforcing ring film and veneer
The root of sealing film covers the form for forming duplicature together, and the intensity and deformation for substantially increasing the sealing of diaphragm are restored
Power.
3, the present invention is also formed with installation slot position in fixed ring, substantially increases the precision and convenient of diaphragm installation
Property.
4, fixed ring of the invention uses polyformaldehyde material, and dual face seals diaphragm uses polyurethane, and anti-corrosion, abrasionproof are prolonged
The service life of entire diaphragm is grown.
