The Automation Research In YGB140/4 Oil Pump For Supplying Oil System

In recent years, with the rapid development of materiel plasm transportation equipment, the application of oil isolation pump become more and more widely-used in the different kinds of fields such as mine, power station and petroleum etc. The oil controller system is the most important key to the oil isolation pump, whose precise, smart and stable work status directly effects the life of Pistons, even the whole result of the oil isolation pump.The control system of oil isolation pump uses manual control, the low control precision, the poor reliability work, failure rate, workers in labor-intensive, so it brings on high failure and inconvenience for maintenance. The topic for the current status of domestic research and the isolation of the oil pump control system studies, take apart the abuse of its abnormal work; the automatic control system has laid a theoretical basis for oil isolation pump. This system not only can improve precision and reliability, but also can deduce the frequent failure, save the maintenance cost, decrease the labor intention and cost etc.We need to according as the operating principle based on controller system so that we can realize the precise control, enhance its efficiency and reliability. Therefore, the research of its control system plays a highly important role in theory and practice.This paper makes a deep analysis on the theory of control system, adopting PLC to replace manual control. Recently, in the field of industrial control, PLC control, application and communication in upper computer configuration becomes a popular technique. With the development of PLC technique, in virtue of its high reliability, advance performance, extensive flexibility in industrial field and convenient performance in extended technics, PLC makes a more and more extensive use in the process of industrial automation control.Regarding the general design method of PLC control system, basic measure application in system reliability, we highly discuss design method on hardware and software of PLC control system. With the technique of PLC and configuration, it can automatically design for the whole control system.Through the choice and design of PLC control and configuration during the process of oil isolation pump operation, the paper analyzes and discusses the specific question, drafting the relative working flow chart for oil isolation pump, hardware configuration for automatic control system, as well as software flow chart. Moreover, it also finishes the debug in automatic control system. To sum up, the oil isolation pump controlled by PLC, owns a high quality and stable performance, completely satisfy the design requirement. Moreover, it can be taken an example of designing in the similar automatic control system of oil isolation pump.
