IDS are ABB Inverter specialists. We specify, install, commission, repair, service and hire variable speed drives.
Cavitation is generally bad news for dairy producers, and its effects can have a severely negative impact on the performance and lifetime of pump systems. ABB’s Andrew Bould looks at how variable speed drives (VSD) can be used to combat it. The dairy industry relies heavily on pumps to transport raw and processed product from […]
David Hughes, Managing Director for ABB in the UK, reflects on the past, present and future of the ubiquitous variable speed drive as new generation of engineers are increasingly becoming aware of its advantages. The Past The variable speed drive (VSD) is now over 50 years old. Its purpose in life, from then to now, […]
We are pleased to announce that following the success of the ABB variable speed drive webinars in 2020, ABB and IDS are once again teaming up to provide these valuable online learnings. The experts at ABB have created these webinars with the intention of sharing knowledge and best practices. The webinar topics run from an […]
Sludge Density Pump Control or Reactive Pump Control (RPC) Introduction Sludge is created when a liquid containing solids is settled. Typically, this can be in PSTs (Primary Settling Tanks) or Humus Tanks in sewage treatment works. Alternatively, it can occur in mineral processing plant in clarifiers. The pumps that take the sludge from the bottom […]
Inverters rectify ac to dc then chop it up again with transistors to provide a variable frequency, variable voltage pseudo ac to create a variable speed motor from a fixed speed ac motor. This chopping takes place many times a second from around 1kHz to 16kHz. This is the switching frequency. At lower switching frequencies, […]
Also known as variable speed drives or VSD/VFD, an inverter is a clever box which sits between the electrical supply and an electric motor. What Does An Inverter Do? An inverter changes the fixed frequency from the mains to a variable frequency output, in turn this can change the speed of the motor, which can […]
As the water industry moves towards AMP 7 (asset management plan), among the key challenges facing the sector is ensuring maximum uptime of the installed base of pumps and their motors and drives. ABB‘s Clayton Mead, UK Water Manager – Drives, offers some advice. Whereas previously pumps, motors or drives had a back up that […]
Our engineers are used to visiting large industrial plants, remote water treatment sites as well as mines and quarries. Whilst the scenery en-route to these premises can be breathtaking, it made a welcome change for us to visit the picturesque seaside town of Weymouth. SEA LIFE Weymouth is set across a 7 acre Park with […]
ABB’s Andrew Bould explains why fixed torque applications shouldn’t be overlooked as candidates for variable speed drive installation. When we talk about variable speed drives (VSDs), the focus is very often on energy saving. Indeed, in variable torque applications like fans and pumps they can reduce energy costs by up to 60 percent. However, when […]
Clayton Mead, UK Water Manager – Drives, ABB Limited, writes: As we move towards AMP 7, among the key challenges facing the water industry remains one of asset health: how to ensure that the installed base of pumps and their motors and drives never let you down. Whereas previously pumps, motors or drives had a […]
