Abstract
The utility model discloses a pneumatic diaphragm pump. The pneumatic diaphragm pump comprises an air cylinder body, a piston, a diaphragm, diaphragm screens used for blocking the diaphragm, two floating balls and a shell, wherein the shell is connected with the air cylinder body, the diaphragm is connected between the air cylinder body and the shell, the diaphragm screens are arranged on the two sides of the diaphragm, the diaphragm screen I is connected to the side face of the shell, the diaphragm screen II is connected to the side face of the air cylinder body, both the two diaphragm screens are arc-shaped faces, the shell is provided with a liquid outlet and a liquid inlet, and the floating balls are arranged on the liquid outlet and the liquid inlet respectively. The pneumatic diaphragm pump is simple in structure, isolation between an air cylinder and chemical liquid can be achieved through the diaphragm, and corrosion caused by the chemical liquid is avoided. In addition, the cross section of the diaphragm II is changed to be in a cone shape, and therefore the air pressure can be uniformly borne by the diaphragm, and the service life of the diaphragm is prolonged.
Description
Technical field
The utility model relates to a kind of membrane pump with pneumatic drive, belongs to field of mechanical technique.
Background technique
When pumping has the chemical liquids of special nature, the impurity that chemical liquids can be corroded in piston or chemical liquids can stop up piston, make pump lose effect, or pump is corroded, how can realize and to get final product this chemical liquids of pumping, can not damage the pump housing again, extend the working life of pump simultaneously, be the object of the utility model research.
Model utility content
The utility model provides a kind of membrane pump with pneumatic drive, and this diaphragm pump structure is simple, can realize the separated of cylinder and chemical liquids, guarantee cylinder its around parts be not corroded.
For solving above technical problem, the utility model provides following technological scheme: a kind of membrane pump with pneumatic drive, comprise the barrier film web plate of cylinder block, piston, barrier film, barrier membrane, two ball floats and housing, described housing is connected with cylinder block, between cylinder block and housing, be connected barrier film, the both sides of barrier film are provided with barrier film web plate, a barrier film web plate is connected to the side of housing, for barrier film web plate I, another piece barrier film web plate is connected to the side of cylinder block, for barrier film web plate II, two blocks of barrier film web plates are arc shaped surface; Described housing is provided with liquid outlet and liquid inlet, and liquid outlet and place, liquid inlet are provided with ball float.
Further, the sectional shape of described barrier film web plate II is taper, and small end is near cylinder block, and large end is near barrier film.
This membrane pump with pneumatic drive that the utility model relates to, simple in structure, by barrier film, can realize the isolation of cylinder and chemical liquids, in order to avoid chemical liquids corrosion.In addition, the sectional shape of barrier film web plate II changes taper into, can make barrier film be subject to air pressure even, extends the working life of barrier film.
Accompanying drawing explanation
Fig. 1 is a kind of membrane pump with pneumatic drive structural representation of the utility model;
Embodiment
As shown in Figure 1, membrane pump with pneumatic drive comprises barrier film web plate, ball float 6 and ball float 7 and the housing 8 of cylinder block 1, piston 2, barrier film 3, barrier membrane 3, described housing 8 is connected with cylinder block 1, between cylinder block 1 and housing 8, be connected barrier film 3, the both sides of barrier film 3 are provided with barrier film web plate, and a barrier film web plate is connected to the side of housing, for barrier film web plate I4, another piece barrier film web plate is connected to the side of cylinder block, is barrier film web plate II5, and two blocks of barrier film web plates are arc shaped surface; Described housing is provided with liquid outlet and liquid inlet, and liquid outlet and place, liquid inlet are provided with ball float.
The sectional shape of barrier film web plate II5 is taper, and small end is near cylinder block 1, and large end is near barrier film 3.
