Controlling the Flow Capacity of a Metering Pump

Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute Stroke Length ...

Fuzzy maximum power extraction control for a photovoltaic water pumping system

AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

Detailed dynamic pumping energy models for optimization and control of wastewater applications

Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this unbalance in the coupled submodels. The model is ...

Controlling the addition of Chlorine into a Process

There are several methods for controlling the addition of chlorine into a process. These methods include flow proportional injection, ORP (oxidation reduction potential) or a residual chlorine analyzer. Each method measures a different process characteristic. Depending on the specific type of process being controlled, there generally is a best choice for controlling the injection of either ...
