Abstract
The utility model discloses a sealing structure for a membrane pump comprising a shell and a shell bracket which are correspondingly matched and installed in a fastening way. A membrane is arranged between the shell and the shell bracket, and is provided with at least one flexible sealing piece capable of prepressing deformation amount. The sealing structure utilizes one flexible sealing piece to once solve the problems that water leaks outsides the shell from the interior of a pump shell and leaks on the end surface of a motor through a hole on the shell bracket under the high pressure condition. Because the flexible sealing piece arranged on an extension region of the membrane, the pump head leakage region is caused to be only arranged at the combination part of the shell and the shell bracket, thereby leakage towards the direction of a hole in the shell bracket is completely avoided; the same one flexible sealing piece is used for preventing leakage, and a leakage prevention link is reduced, thereby the quality of a product is further enhanced.
Description
Technical field
The utility model relates to reverse osmosis water purification machine with the technical field of diaphragm pump, and particularly a kind of diaphragm pump sealing configuration is used for the outer percolating water that prevents of diaphragm pump.
Background technique
The diaphragm pump structure that uses in the just present water purification machine also mainly is to adopt the diaphragm technology.Its main constituent elements has: eccentric wheel, eccentric mounting, diaphragm, chamber of septum, fluid chamber and link etc.Eccentric wheel links to each other with motor output shaft, diaphragm is fixed on the eccentric mounting, and form sealing with the chamber of septum interference fit, chamber of septum links to each other with fluid chamber, be equipped with seal ring therebetween, thereby form water-inlet cavity, water chamber and compression chamber, the turnover water cavity communicates with compression chamber respectively, and being separated by with safety check forms the one-way flow of current.In diaphragm pump work, driven by motor eccentric wheel, past eccentric wheel and eccentric wheel seat rotatablely move and change into axial motion and pass to diaphragm, change shape and form the to-and-fro motion of similar piston by the elastomeric products of the material of diaphragm own.Because most diaphragm all adopts flat design at present, or slightly conical surface design, the tractive distortion that makes diaphragm be subjected at work is very serious, to-and-fro motion for a long time, the permanent plastic deformation of attenuation will take place in diaphragm, makes the diaphragm reduction in strength, thereby causes water leakage phenomenon.Along with increasingly matureization of reverse osmosis system water-treating equipment, wherein the important fitment membrane pump performance requirement of reverse osmosis water-treating equipment is also perfect gradually, and special in the explosion test event in the NSF58 standard, old sealing configuration is difficult to satisfy its requirement.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of structure tight, and plastic deformation is little, can effectively prevent the diaphragm pump sealing configuration of percolating water outside shell holder internal holes direction.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of diaphragm pump sealing configuration, the housing and the shell holder that comprise the fastening installation of relative engagement, the measure of taking comprises: be provided with diaphragm between housing and the shell holder, diaphragm is fitted with the soft material Sealing of at least one energy precompressed amount of deformation.
The measure of taking also comprises:
Be shaped on upwardly extending first all flangings and second all flangings on the above-mentioned diaphragm outer circumferential face, first all flangings and second all flangings constitute recessed all grooves; Soft material Sealing is positioned at recessed all grooves, and is close on the face in recessed all grooves, and diaphragm pump housing lower end has at least one side to be complementary to be close to described soft material Sealing to contact.
Be shaped on the edge side face of extension on the above-mentioned diaphragm outer circumferential face, soft material Sealing is close on the B face of edge side face, and diaphragm pump housing lower end has at least the recessed side face of a circle to be close to contact mutually with soft material Sealing.
Compared with prior art, the utility model adopts between housing and the shell holder and is provided with diaphragm, and diaphragm is fitted with the soft material Sealing of at least one energy precompressed amount of deformation.It utilizes the disposable solution of a soft material Sealing under high-pressure situations, and water leaks on the motor end face outside housing and through the hole on the shell holder from the pump case internal leak.Owing to used soft material Sealing is placed on the elongated area of diaphragm, make the pump head leakage region only in junction from housing and shell holder, avoid fully leaking towards shell holder internal holes direction; Prevent to leak with same soft material Sealing, reduce the leakproof link.Thereby further improved the quality of product.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one as shown in Figures 1 to 4, a kind of diaphragm pump sealing configuration, comprise the housing 5 and the shell holder 6 of the fastening installation of relative engagement, be provided with diaphragm 1 between housing 5 and the shell holder 6, diaphragm 1 is fitted with the soft material Sealing 4 of at least one energy precompressed amount of deformation.
Embodiment one is shaped on upwardly extending first all flanging 1a and second all flanging 1b on diaphragm 1 outer circumferential face, first all flanging 1a and second all flanging 1b constitute recessed all groove 1c; Soft material Sealing 4 is positioned at recessed all groove 1c, and is close on the A face in recessed all groove 1c, and diaphragm pump housing 5 lower ends have at least one side to be complementary to be close to soft material Sealing 4 to contact.
Installation process: soft material Sealing 4 is placed in recessed all groove 1c of diaphragm 1, and is close on the interior A face of recessed all groove 1c, the diaphragm pump housing 5 that closes again utilizes fastening piece that diaphragm pump housing 5 and shell holder 6 are tightly locked together; The pressure of locking has at least one side to be complementary to be close to soft material Sealing 4 diaphragm pump housing 5 lower ends to contact.Soft material Sealing 4 has certain precompressed amount of deformation after assembling.The utility model utilizes soft material Sealing 4 disposable solutions under high-pressure situations, and water leaks on the motor end face outside housing and through the hole on the shell holder 6 from the pump case internal leak.Owing to used soft material Sealing 4 be placed on the elongated area of diaphragm 1, make the pump head leakage region only in junction from diaphragm pump housing 5 and shell holder 6, avoid fully leaking towards shell holder internal holes 6a, 6b, 6c direction, prevent to leak with same soft material Sealing, reduce the leakproof link, thereby further improved the quality of product.
Are the edge side face 1d that are shaped on extension on diaphragm 1 outer circumferential face as Fig. 5 to embodiment two shown in Figure 6, and soft material Sealing 4 is close on the B face of edge side face 1d, and diaphragm pump housing 5 lower ends have at least the recessed side face of a circle to be close to contact mutually with above-mentioned soft material Sealing 4.
