Regulation properties of pumping station control system in the highest efficiency range

This paper introduced a design and implementation of heat exchange station control system based on PLC and industrial configuration software, including the control scheme and principle, hardware selection and software design, etc. The circulating pumps and replenishing pumps in the system can all be driven automatically by PLC and inverter. Main process parameters e.g. steam pressure and measurement temperature can all be shown on the industrial PC running configuration software, and instructions could be sent by the engineer and operator on-the-spot via the Human Machine Interface as well. The automatic pressures adjustment of steam supply of the heater by advanced PID algorithm has been realized finally. It is verified that the system is highly reliable and stable, and it greatly enhances the level of automation and pressure control accuracy of the heat exchange station and meets all the equipments running demands well.

Sewage pumping station is pumping station import at the sewage treatment plant. Its role is to collect the wastewater from the sewage pipe network to subsequent wastewater treatment process facilities. The water level is usually low in sewage collection pipe network. And many wastewater treatment facilities is based on elevation settings. So it is necessary to use lift pump to improve lift of the collected sewage, using high gravity sewage errands subsequent process in order to reduce energy consumption. The traditional way of pumping generally has the shortcomings: the waste of power resources, low efficiency, poor reliability, low degree of automation, which seriously affects the urban sewage treatment capacity. This paper, views pump station control system at the sewage treatment plant as the background, researches frequency control constant pressure control system based on PLC, realizes the energy efficient, automated and reliable direction of development of the sewage pumping station.
