Pneumatic diaphragm pump with controller

Abstract

The invention relates to a pneumatic diaphragm pump with a controller. The pneumatic diaphragm pump with the controller comprises the pneumatic diaphragm pump, the controller, a touch screen control panel, a solenoid valve, an air compressor, a pressure sensor and a flow meter, wherein the controller is connected with the pneumatic diaphragm pump, the touch screen control panel, the solenoid valve, the pressure sensor and the flow meter through signal wires; the air compressor is connected with the pneumatic diaphragm pump through the solenoid valve; the pressure sensor is mounted at an outlet of the pneumatic diaphragm pump and is used for detecting the outlet pressure of the pneumatic diaphragm pump and sending a detected result to the controller; the flow meter is mounted at the outlet of the pneumatic diaphragm pump and is used for detecting the liquid flow at the outlet of the pneumatic diaphragm pump and sending the detected result to the controller; the touch screen control panel is used for displaying the pressure and flow and setting a pressure threshold value and a flow value. The pneumatic diaphragm pump with the controller provided by the invention can be used for effectively preventing the accidents caused by pipeline blockage.

Description

technical field [0001] The invention relates to a pneumatic diaphragm pump with a controller. Background technique [0002] Pneumatic diaphragm pump is a new type of conveying machinery. It uses 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. . Because the pneumatic diaphragm pump uses compressed air as the power source; when exhausting, the pump expands and absorbs heat so that the pump body will not overheat; it can pump various particulate, toxic, and chemically unstable liquids; small volume , Small footprint, easy to move, high flexibility and other incomparable advantages of other pumps, making pneumatic diaphragm pumps widely used in all walks of life in our country. [0003] However, the pneumatic diaphragm pump also has its unsatisfactory place. On the one hand, because the pneumatic diaphragm pump can suck and pump high-viscosity liquid with part...

Problems solved by technology

[0004] Aiming at the defects existing in the prior art, the present invention provides a pneumatic diaphragm pump with a controller, mainly to solve the accident caused by excessive pressure at the outlet of the pneumatic diaphragm pump due to the blockage of the pipeline in the system where the pneumatic diaphragm pump is located, and In order to prevent the air-operated diaphragm pump from running dry, the operating frequency of the diaphragm of the diaphragm pump is too fast under the action of compressed gas, which reduces the service life of the diaphragm of the diaphragm pump and reduces the service life of the diaphragm pump.
