Water and Waste
High efficiency pump control systems
Water companies are under unprecedented pressure from rising
energy costs as well as legislative and climate change. Developing
strategies to reduce operating costs whilst optimising the
performance of assets is critical. Control Techniques provide new
solutions to enhance connectivity, reduce energy consumption,
minimise downtime and to react intelligently to real problems as
they occur.
Optimised drive solutions for the Water industry
As market leaders in intelligent drives, Control Techniques’
drives present a new approach to managing your assets. Our products
combine high reliability, compact size and the flexibility to
incorporate additional functionality such as intelligent pump
control, I/O for instrumentation and TCP/IP based telemetry
solutions within the drive.
Control Techniques’ Intelligent Pump Control drive system
Control Techniques’ Intelligent Pump Control (IPC) system
delivers measurable improvements in pumping reliability, up-time
and performance. In real installations it significantly reduces the
costs associated with operating these assets while improving
throughput and availability.
Solutions to real problems
A long standing pumping problem suffered by water companies is
that of ‘ragging’, the fouling of pump impellers in waste water
systems. Manually clearing the problem is a costly and unpleasant
task requiring a maintenance team and frequently a crane. Downtime
may extend to several days during which time the back-up systems
are under additional pressure. A total system failure can result in
effluent leakage with implications for the environment, human
health, clean-up costs and breaches of legislation. Control
Techniques’ IPC system accurately monitors pump performance by
“live” continuous measurement of torque producing current, plus
flow and pump speed where appropriate. The live data is compared to
measured values taken during commissioning, plus expected pump
profile characteristics. Due to the precise nature of the pump
monitoring programme, any “out of profile” performance feedback
triggers an early warning indication of potential pump
ragging/blocking. This initiates an automatic drive based cleansing
cycle programme to help clear the pump impeller. The system is also
able to schedule real time pipe scouring cycles, detect
deteriorating flow and potential impeller wear.
Reducing energy costs and improving processes
Installing variable speed drives to control pump flows to match
operational demand, can significantly contribute to a reduction in
energy consumption and improve process control. In some
applications, intelligent systems are able to further reduce energy
costs by operating during off peak tariffs. Control Techniques
drives provide a kWh reading to allow the energy savings to be
easily monitored.
