LNEYA-22-Chemical Synthetic Process Control System - 1

WUXI GUANYA REFRIGERATION TECHNOLOGY CO., LTD. In order to meet the demand of users, our company develop chemical synthetic process control system and security protection of distributed instrument control system, which upgraded with second extension by our existing dynamic temperature control system. The system not only can auto-control, but also with function of safety interlock protection for dangerous key parameters in the process of production. Chemical Synthetic Process Control System Chemical synthetic process is mainly involved with high temperature and high pressure, inflammable and explosive toxic harmful medium, as some chemical synthetic process be of complex and with enormous energy, it will result in serious consequences of personal and property safety once control unusally or abnormal in the production process. Automatic control system not only can control the production process, but also can protect and give response timely for the worsening condition when operating unsuitable or danger for chemical experiment production device and equipment, in order to reduce the danger acceptably and to ensure the safety of personnel, equipment and production device. Introduction S7-200/s7-300 Series The system with Siemens S7-300 PLC as control station processing unit, to complete the whole process of data acquisition, processing and field control. With 10-inch color touch screen display. The connection between operator and control station of processing units, complete information and transmission of control instruction is realized. And accurately control the temperature, pressure, pump flow, quality, stirring speed, electric valve, charge pump, vacuum, electronic balance and various types of transformation input display. Local Control And Operation In many cases, proess control is required with operation function in the production site, especially in the process of batch-type process, about start-stop of system, the change of parameters which is decided according to the scene of the production readiness and actual production status. It is required that it also need the function of operation control in the production site besides centralized monitoring by control room. Flexible Function, Control Scheme Can Be Customized Engineer can invoke more than 30 types of operation control function and the function block by simple programm method to satisfy the specific and actual control. Save Cost The system is specially designed for small and medium-sized monitoring points,with simple configuration, reasonable price which compared with the control system products of medium large scale. Meantimes, because of distributed system structure, it does not need to connect amount of input/output singnal cables to central control room, and greatly reduce the user cost.
