Pipeline filters in order to ensure the safe and reliable production of the sewage treatment process continuity, increase the level of automation, and adapt to the sewage treatment process, the process and characteristics of the project, s tarting from the actual situation of the project, the the pipe filter control system uses in centralized PC control room management and monitoring, site the decentralized control computer control system. Pipe filter system consists of a central control room computer and on-site terminal.filter bag manufacturers

Pipe filter set computer technology, control technology, communication technology and display technology in one, central monitoring station and a number of on-site sub-station is connected through communication networks, centralized monitoring and distributed control. Overcome such centralized control system risk concentration, poor reliability, easy to expand, control cable defects such as large amount. Information, scheduling, concentrate on the management and control of dangerous dispersed. Among the control room computer failure each site sub-station can be independent, stable work, and fundamentally improve t he reliability of the system. At the same time according to need access to the LAN or Internet Internet to implement remote monitoring.

The pipeline filter the automatic control system design for the Pipeline Fire Control field set operation box implementation of the on-site control of the device, the central control system can be set up in the control room to the implementation of remote centralized control, a PLC and industrial control configuration in the control room at the same time machine for security control to design a simulation process screen in the control room, the station of the wastewater flow and control point device operating conditions. Pipe filter device control object: 60 pumps, 86 pneumatic control valve, 13 units mixer, 38 level control point, three temperature measurement points, a flow detection points, 47 alarm points.
