Problems solved by technology
[0004] The present invention provides a controllable pneumatic double-diaphragm diaphragm pump to solve the deficiencies of the prior art, which mainly solves the problem of inaccurate control of the guide rod of the previous double-diaphragm pump, complex design, high component loss, and high repair rate. , this patent has completely got rid of the principle of using the combination of guide rod and air pressure to push the diaphragm in the previous technology. This patent only uses the ventilation change of air pressure to complete the function of the entire product

Embodiment Construction
[0019] In order to describe the structure of the present invention more specifically and in detail, further elaboration will be made below in conjunction with the accompanying drawings.
[0020] As shown in the figure, the patent is divided into five parts as a whole, which are respectively the left air chamber 1, the driving device 2, the right air chamber 3, the upper discharge pipe 4, and the lower feed pipe 5; the left air chamber 1 and the right The outside of the air chamber 3 is integrated with the feeding pipe section of the feed pipe 51 respectively; the left air chamber 1 and the right air chamber 3 are separated by a diaphragm 31, and are divided into two chambers, one is a liquid chamber and half is a gas chamber; The diaphragm is clamped by the outer gasket 32, the outer anti-leakage ring, the inner anti-leakage ring, and the inner gasket 37, and passed through by the connecting bolt. The structure of the two chambers is the same; the positions are opposite; the t...

The invention relates to a double diaphragm pump, in particular to a controllable pneumatic double diaphragm pump, aiming to solve the problems that the traditional double diaphragm pump is inaccurate in guide rod control, complicated in design, high in loss of parts and high in repair rate. In order to realize the aim of solving the problems in the traditional double diaphragm pump, the controllable pneumatic double diaphragm pump comprises a left air cavity chamber, a right air cavity chamber and a middle actuating device, wherein the left air cavity chamber and the right air cavity chamber are connected with an upper discharge tube and a lower feed tube; diaphragms are respectively arranged in the left air cavity chamber and the right air cavity chamber and are connected through a center slide bar; the actuating device comprises a balance adjustment device, an exhaust silencer and a balance admission pipe, wherein the balance adjustment device is connected with the balance admission pipe and the exhaust silencer; and inner side walls of the left air cavity chamber and the right air cavity chamber are provided with airflow holes for communication of the actuating device. From the technical scheme, the actuating device adopts the balance adjustment device, the exhaust silencer and the balance admission pipe instead of parts such as the guide rod and the like in the prior art.
Description
technical field [0001] The invention relates to a double-diaphragm pump, in particular to a controllable pneumatic double-diaphragm pump. Background technique [0002] Pneumatic diaphragm pump is a new type of conveying machinery, and it is the most novel type of pump in China at present. Using compressed air as the power source, it can pump all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. The pneumatic diaphragm pump has four materials: engineering plastics, aluminum alloy, cast iron, and stainless steel. The pneumatic diaphragm pump adopts nitrile rubber, neoprene, fluororubber, polytetrafluoroethylene and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. It is placed in various special occasions and used to pump media that cannot be pumped by conventional pumps, and has achieved satisfactory results. Due to the use of air as power, the flow rate is aut...
