新型变频恒压供水设备的应用

The application of new pattern frequency conversion and constant pressure to water supply equipment

沈阳理工大学融通科技开发公司开发生产的新型变频恒压供水设备,采用带有內置PID功能及内置水泵逻辑控制功能的变频器,降低了设备成本,提高了生产效率及设备的可靠性,节省了安装调试时间。新型供水设备经一年多的实际运行证明:系统运行可靠、性能满足要求。

At present,the water supply equipment of frequency conversion and constant pressure,always used with the programmable logic controller of the analog input / analog output or PID regulator,the PID algorithm programming and programmable logic controller programming are very difficult ,equipment costs are high and it's difficult to debug.In order to resolve these questions,the water supply equipment of constant pressure was produced,which is using the built-in PID function and built-in pump logic control functions,reducing equipment costs and improve production efficiency and equipment reliability,savings the installation and debugging time.
