It is a common challenge for public utilities to manage multiple pumps with variable pressure levels during the day. The goal for pumping stations is using less energy and longer usable lifetime for sustainable development a business opportunity.

Historically, green practices may have reduced waste, saved energy, and minimized pollution, but the  implementation would often cost more money than they saved. According to Omron’s Green Automation solutions, doing what’s best for the environment now means doing what’s best for the organisation’s bottom line.

Omron electronically controlled variable speed drives can provide a gradual start-up and shutdown of the motors, and this reduces the energy consumed. It also reduces the mechanical and electrical stress on the components, and therefore significantly extends the system’s lifetime.

These two factors make electronic control of pumping stations not only an important business issue but also a major advance towards sustainable development, whilst delivering financial savings of between 30 and 60%.

Overall control system

With the combination of proven products, users can create a flexible and easy-to-use control system that gives complete full control over pumping applications.  By adding a single pressure sensor to the n-pumps, users can monitor the exact pressure level inside the hydraulic plumbing, and ensure smooth profiles.

All possible measurement mistakes are eliminated by connecting the 4-20 mA sensor directly to the PLC, which closes the PID loop for all drives, with commands sent by the PLC to the Omron SX industrial drives, and give feedback on alarm signals.

The Omron SX inverter is designed to drive high power applications, anything from pumps, fans, compressors or blowers through to closed loop vector control required by cranes, crushers, mills or mixers up to 800 kW. The standard inverter has built-in application oriented software and it’s hardware design provides flexibility to the user. In addition, an NS touch-screen provides a user-friendly interface to the system.

Results:

– 30-60% energy saved

– Enhanced efficiency

– Improved diagnostics (built-in Modbus)

– Flexible, integrated solution with PLC easy access

– Minimized environmental impact
