  • TCU temperature control model selection and technical parameter description

    TCU temperature control is also a two-cycle unit single-fluid temperature control system. When selecting the model, it is very important for the whole temperature control reaction. Only the appropriate reaction system is used to exotherm and absorb the whole reaction process. The heat responds to the entire control, so ...

  • A visual tool to calculate optimal control strategy for non-identical pumps working in parallel, taking motor and VSD efficiencies into account

    A simple graphical tool was developed, that finds the optimal combination of pumps and their rotational speeds for all possible working points for a pump battery. The tool was integrated into EPANET as well as EPA SWMM simulation packages. The tool allows us to analyse and optimize operation non-identical parallel pumps with different minimum and maximum frequencies for all possible working ...

  • Non-contacting Ultrasonic Pumping Station Flow Measurement Saves Money for Dwr Cymru Welsh Water

    Dwr Cymru Welsh Water has benefitted from the unique 'Pumped Volume' feature built into Pulsar's Quantum 2 Pump Station Controller; identifying a flow problem within a pumping station network without the need for expensive Magflow meters. Once the issue was resolved, pumped volume through one of the stations was reduced by 88% , ...

  • A robust approach based on time variable trigger levels for pump control

    An approach for the control of a pumping plant feeding a tank at the inlet of a water distribution system is presented. The approach is aimed at minimizing the energy costs by maximizing pumping during off-peak electricity tariff periods. It is based on trigger levels which are variable during the day according to a prefixed pattern in order to ensure that the water level in the elevated tank ...

  • What You Need to Know about Electronic Automation of Hydraulically-operated, Diaphragm-actuated Control Valves

    Hydraulically controlled, diaphragm-actuated control valves are the mainstay of the waterworks industry to control pressure, flow, level, pump control, and at times to meter. These automatic control valves are controlled by pilots to do specific tasks and are mainly single-set-point systems. With the need to remotely actuate and control the valves and the applications becoming more complex, ...

  • CSV’s replace VFD’s case study

    Variable Frequency Drives or VFD’s do not save energy! It is a myth that VFD’s save energy. The average person and even many “experts” may think it completely logical that reducing the RPM of a pump also reduces the amount of power used. This is Absolutely False!! A VFD always causes more energy to be used per gallon produced. The Cycle Stop Valve or CSV is ...

  • Cycle Stop Valves verses Constant Pressure Pumps case study

    The newest innovation in pump control technology is "constant pressure valves". The name "constant pressure valve" was coined several years ago by Cycle Stop Valves or CSV. Some people would like you to believe that variable speed pumps, VFD, or so called "constant pressure pumps" are the most modern pump control system. In reality VFD was introduced in 1968, and because of the laws of physics, ...

  • Frequency pressure regulation in water supply systems

    In water supply systems, pressure management in most cases is proven to be the most cost-effective activity related to water loss control. As an advanced method of pressure control, it is possible to use variable frequency drives for centrifugal pump control. Pressure regulation can be performed with constant pressure or with proportional pressure control. The application of proportional ...
