Pneumatic diaphragm pump (online) comprehensive performance testing platform, customized and designed according to relevant industry testing standards and customer testing requirements. The equipment meets the production line comprehensive performance testing of 1-inch pneumatic diaphragm water pump products. Through testing, various parameters of the pneumatic diaphragm pump before leaving the factory were tested, including suction test, minimum starting air pressure test, working condition noise test, working condition vibration test, working condition flow rate test, static pressure holding test, chamber changing dynamic pressure holding test, peak flow rate test, etc., and controlled by the upper computer control software. Automatically determine NG and OK modes by setting relevant test parameters, upper and lower limit parameters, and other judgment parameters. Automatically record and generate corresponding pressure flow curves for relevant test parameters. The system automatically saves and generates test reports, etc
