Pneumatic diaphragm pump detection system

Abstract

The invention discloses a pneumatic diaphragm pump detection system. A testing module (100), an electric control module (200) and a display operation module (300) of the system are sequentially connected, the testing module (100) comprises an air pressure regulating and reducing valve (1-1), an air pressure sensor (1-2), a temperature sensor (1-3), an air flow meter (1-4), electromagnetic valves (1-5), pneumatic diaphragm pumps (1-6), needle valves (1-7), liquid flow meters (1-8), liquid pressure sensors (1-9), an electric regulating valve (1-10), a water storage tank (1-11) and a ball valve (1-12). The electric control module (200) comprises a PLC (2-1) and a flow computing instrument (2-2). The display operation module (300) is used for receiving and displaying digital information, according to a preset processing mode in the operation module, data are processed and then fed back to the testing module (100) through the electric control module (200), and the module comprises a display module (3-1) and an operation module (3-2). The pneumatic diaphragm pump detection system can improve the detection efficiency and precision of the pneumatic diaphragm pumps, and is convenient to operate and capable of detecting the pneumatic diaphragm pumps of different diameters.

Description

technical field [0001] The invention belongs to the field of diaphragm pump detection and relates to a pneumatic diaphragm pump detection system. Background technique [0002] Pneumatic diaphragm pump is a kind of liquid conveying machinery, which has been developed rapidly in domestic application. Due to the unique flow channel type inside the pneumatic diaphragm pump and the rotating motion of the impeller, there are always random changes in the flow field inside the pump body, especially the impeller, such as vortex, shedding, secondary backflow, etc., which makes the pump inside The unsteady turbulent flow becomes more complicated, precisely because the movement process of the fluid in the pneumatic diaphragm pump is so complicated that it is impossible to completely describe the motion characteristics of the pneumatic diaphragm pump under different working conditions with a complete mathematical analysis formula. Therefore, even if a relatively complete theory of fluid...
