Abstract
The invention discloses a pneumatic diaphragm pump. The pneumatic diaphragm pump comprises a cylinder block, a piston, a membrane, membrane net plates for blocking the membrane, two floating balls and a housing, wherein the housing is connected with the cylinder block; the membrane is connected between the cylinder block and the housing; both sides of the membrane are provided with the membrane net plates, in which one membrane net plate is connected with the side face of the housing and is a membrane baffle plate I, the other membrane net plate is connected with the side face of the cylinder block and is a membrane baffle plate II, and the two membrane net plates are arc-shaped surfaces; the housing is provided with a liquid outlet and a liquid inlet; and the floating balls are arranged at the liquid outlet and the liquid inlet. The pneumatic diaphragm pump disclosed by the invention is simple in structure, and can realize isolation of a cylinder from chemical liquid through the membrane so as to prevent being corroded by the chemical liquid. Moreover, the shape of the cross section of the membrane net plate II is cone-shaped, so that air pressure of the membrane can be uniform, and the service life of the membrane is prolonged.
Description
Technical field
The present invention relates to a kind of membrane pump with pneumatic drive, belong 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 the chemical liquids can stop up piston, make pump lose effectiveness, or pump corroded, how can realize getting final product this chemical liquids of pumping, can not damage the pump housing again, prolong the working life of pump simultaneously, be the purpose of the present invention's research.
Summary of the invention
The invention provides a kind of membrane pump with pneumatic drive, this diaphragm pump structure is simple, can realize separating of cylinder and chemical liquids, guarantee cylinder around it parts be not corroded.
For solving above technical problem, the invention 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, is connected barrier film between cylinder block and the housing, the both sides of barrier film are provided with the barrier film web plate, a barrier film web plate is connected the side of housing, is barrier film baffle plate I, and another piece barrier film web plate is connected the side of cylinder block, be barrier film baffle 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 big end is near barrier film.
This membrane pump with pneumatic drive that the present invention relates to, simple in structure, can realize the isolation of cylinder and chemical liquids by barrier film, in order to avoid the chemical liquids corrosion.In addition, the sectional shape of barrier film web plate II changes taper into, can make barrier film be subjected to air pressure even, prolongs the working life of barrier film.
