Abstract
The utility model discloses an improved septum pump, which comprises a motor body. One end of the motor body is connected with a transmission seat body, and the other end of the transmission seat body is connected with a pump chamber. A septum is arranged between the pump chamber and the transmission seat body; a protecting film is also arranged between the septum and the transmission seat body; a connecting point of the inner part of the transmission seat body near the pump chamber is inbuilt with a metal stiffener. The protecting film is made of Teflon materials, and is not adhesive, abrasion resisting and chemical corrosion resisting basically. The protecting film can protect internal body of the transmission seat body from chemical corrosion under the condition that the septum is corroded and damaged, and the connecting point of the inner of the transmission seat body near the pump chamber is inbuilt with the metal stiffener, thus the septum pump has the effects of light weight, corrosion resistance and strong rigidity.
Description
Technical field
The utility model relates to a kind of improved diaphragm pump.
Background technique
Diaphragm pump of the prior art, its structure mainly is by barrier film is set the inner space of pump to be divided into operation unit and operating member, be provided with reciprocating piston at operating member, to-and-fro motion by piston, propelling fluid makes barrier film carry out reciprocating action, to reach the reciprocal operating type that the liquid of operation unit is drawn and discharged.
Existing diaphragm pump is except that the size of considering its power; its structural strength is also needed corresponding configuration; for example among the Taiwan patent TW510947; propose a kind of improvement project of carrying out, can avoid the structural failure that when power improves, caused, but this pump is when the occasion of Environmental Engineering is used at barrier film; only improve power; and obviously not enough to the protection of other structure, also promptly when the pH value of liquid during, may cause the damage of internal structure such as barrier film greater than bearing value.
In addition, be a more unvalued ring for a long time for the reinforcement of pump external structure in the prior art, in other relevant correlative study of document, to diaphragm pump, though different structure applications designs is arranged, also rarely found have a report that external structure is discussed.
The improvement that focuses on discussing existing externally structural disappearance of diaphragm pump and function of the present utility model.When power ascension and when cooperating internal structure to change, in the using process of diaphragm pump, because of it cooperates the structure of covering barrier film, its stressed will increasing greatly; And belong to other assembly type because of membrane configuration, therefore will on body, cause the junction, and this junction point and import and export two ends respectively can be for the fluid turnover, obvious this inevasible junction point, certainly will cause the weakness on the overall structure, when work done, sealing improper and when maintenance, the as easy as rolling off a log liquid spill that causes, and have influence on ectosome.And general ectosome is metallic material, and the corrosion resistance of this kind metallic material is not enough to some extent, after long-time the use, causes the corrosion of junction outer surface easily, and then causes the outer part of metal and spiral shell spare impaired, damages the pump housing and increase and disassembles difficulty when changing.
So, how a kind of corrosion proof function that both had is provided, it is low and carry mobile pump easily to have cost again, is the emphasis of practitioner's research of the sector, also is creation point of the present utility model place.
Summary of the invention
The utility model purpose provides a kind of improved diaphragm pump; be provided with protective film between its barrier film and the transmission pedestal; it is the Furtulon material; do not adhere to, wear-resistant, be not subjected to chemical erosion substantially; under barrier film is corroded damaged situation; this protective film can protect the inner body of transmission pedestal to avoid chemical corrosion, and the joint that transmission pedestal internal interface is bordering on pump chamber is embedded with metal reinforcement spare, the utlity model has effect in light weight, anticorrosive and that rigidity is strong thereby make.
The technical solution of the utility model is: a kind of improved diaphragm pump, comprise motor body, end in motor body is connected with the transmission pedestal, the other end of transmission pedestal is connected with pump chamber, be provided with barrier film between pump chamber and the transmission pedestal, also be provided with protective film between barrier film and the transmission pedestal, transmission pedestal internal interface is bordering in the joint of pump chamber and is embedded with metal reinforcement spare.
The further technological scheme of the utility model is: a kind of improved diaphragm pump, comprise motor body, end in motor body is connected with the transmission pedestal, the other end of transmission pedestal is connected with pump chamber, be provided with barrier film between pump chamber and the transmission pedestal, also be provided with protective film between barrier film and the transmission pedestal, transmission pedestal internal interface is bordering in the joint of pump chamber and is embedded with metal reinforcement spare; Described protective film is the Furtulon material; Described transmission pedestal is anticorrosive thermoplasticity material; Described thermoplasticity material is teflon, polychlorotrifluoroethylene, poly-perfluor third ethene, polypropylene, ABS.
The utility model advantage is:
1. be provided with protective film between its barrier film of the utility model and the transmission pedestal; it is the Furtulon material; do not adhere to, wear-resistant, be not subjected to chemical erosion substantially, under barrier film was corroded damaged situation, this protective film can protect the inner body of transmission pedestal to avoid chemical corrosion.
2. transmission pedestal of the present utility model is to make with erosion-resisting thermoplastic material, therefore it can effectively prevent erosion, the disappearance of the excessive and outer surface that environmental factor causes of fluid, and the spiral shell spare that also can avoid transmission pedestal and pump chamber junction point is corroded and not quick detachable.
3. the utility model transmission pedestal internal interface joint of being bordering on pump chamber is embedded with metal reinforcement spare, thereby makes the utility model when utilizing thermoplastic material, still has suitable rigidity, reaches preferable structural.
4. the utility model utilizes erosion-resisting thermoplastic material, can make whole weight significantly alleviate, and reaches portative purpose.
Description of drawings
Fig. 1 is the utility model decomposition texture schematic representation;
Fig. 2 is the utility model composite structure schematic representation;
Fig. 3 is a generalized section of the present utility model.
Wherein: 10 motor bodies; 20 transmission pedestals; 21 joints; 22 stiffeners; 30 pump chambers; 31 barrier films; 32 protective films; 40 spiral shell spares.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as Fig. 1, Fig. 2 and shown in Figure 3, a kind of improved diaphragm pump comprises motor body 10, is connected with transmission pedestal 20 in an end of motor body 10, the other end of transmission pedestal 20 is connected with pump chamber 30, and is fixing by spiral shell spare 40 between described pump chamber 30 and the transmission pedestal 20.Be provided with barrier film 31 between pump chamber 30 and the transmission pedestal 20, also be provided with the protective film 32 of Furtulon material between barrier film 31 and the transmission pedestal 20.Described transmission pedestal 20 is anticorrosive thermoplasticity material, and described thermoplasticity material is teflon, polychlorotrifluoroethylene, poly-perfluor third ethene, polypropylene, ABS.
The protective film of Furtulon material since the Furtulon material do not adhere to, wear-resistant, be not subjected to the good characteristic of chemical erosion substantially, under the damaged situation of barrier film corrosion, this protective film can protect the inner body of transmission pedestal to avoid chemical corrosion.
