基于流量的水泵运行数据采集系统

基于流量的水泵运行数据采集系统Abstract:Water pump technology is a semi-theoretical and semi-empiricalexperimental subject.Experimental research is of great significance in thedevelopment of water pumps.A pivotal position and role.The author,referring to alarge number of relevant domestic and foreign documents,emphatically discusses thepump flow rate,The testing principle and method of lift,shaft power and rotatingspeed are proposed,and the electric measuring method is combined with motorefficiency.The rate characteristic curve measures the shaft power of the water pump,thus avoiding a large number of complicated intermediate processes in the lossanalysis method.The automatic measurement requirements of the test device are met.The magnetic flux leakage induction coil method is adopted to measure the rotatingspeed of the motor to compensateThe limitation of other rotational speedmeasurement methods to underwater motor testing is overcome,which is suitable forthe development of submersible electric pump by Laing Company.The actual needsof the.On the basis of discussion,the author designs peripheral measurement withsingle chip microcomputer system as the core.The circuit realizes real-time andaccurate data acquisition of output signals of various sensors.In addition,the authoralso analyzed the accuracy of the pump testing system,and analyzed the main errorsof the measuring system The source is discussed,and the mathematical model forselecting the precision of the testing instrument is deduced.In the processing ofmeasurement data,The median filter and quadratic curve fitting technology areadopted to ensure the accuracy of measured values as much as possible from thesoftware.Key words:water pump;Data collection;traffic2
