Frequency Converter Applied In Water Pump Control

This thesis has completed a problem about Frequency Converter applied in waterpump control. It is hydraulic control system which designed by industry localerequirement. It is mostly applied in golf ground and tower water supply etc.Frequency Converter Timing is a timing mode which takes precedence of anyother formerly timing mode. It is utmost benefit,best capability,broad applicationand best promising motor timing technology. It adopts computer control technology,electric technology and motor transmission technology to realize stepless timing ofindustry AC motor and has high efficiency,broad range and high precisioncharacteristics.PLC is the digital electronic system which specially applied in industry. On thebasis of microprocessor, it integrates Computer technology,autocontrol technology.In addition, it is one of standard equipment in advanced industry country. It has madea great leap in miniaturization,maximum,great capacity,better function.It is the control system which includes Frequency Converter technology andPLC technology has many advantages such as :high reliability ,strong anti-jamming,assembly agility,easy program ,maintain convenience and low cost etc.This thesis researches the application of Frequency Converter/PLC in waterpump, analyses many problems in application and characteristic of system, points outachievement in Frequency Converter technology and flaws in application, gives outmeaning,basis,content of research and innovation.
