Research on the Renovation and Reliability of Filter Press Hydraulic Pressure System

According to current status of filter press technology and aiming at solving the existing problems,the simplified and energy-saving designs for the filter press hydraulic pressure system are put forward in order to improve the reliability and reduce energy consumption. Based on PLC and the high-reliability design of electric component,hardware and software,the renovated electric control system is upgraded and has higher degree of automation. Compared with conventional electric relay control system,PLC control can run more safely and reliably,and can be operated more practicality,simply and conveniently. The rebuilt system has smaller volume,higher reliability,lower malfunction frequency,higher ratio of performance with lower price,simpler and more convenient maintenance,and higher operation ratio. With the use of PLC control,flexibility of the system was greatly improved,and the automation and improvement of technology of filter press are realized.
