The variable angle swash plate was invented as a simple and reliable way to transform rotational power into motion and has been the main mechanism used to create variable flow output for almost 120 years. Efforts have been made to digitise the mechanism with feedback and electric control systems and it has served our industries well but it’s time for hydraulics to move out of the analogue age and engage with the benefits of true digital control. a radial piston mechanism and an embedded controller that enables individual cylinders in real time by actuating ultra-fast mechatronic valves. A fundamental innovation The control of individual cylinders also allows a single pump to have multiple independently controllable outlets providing industry innovators Invented by Artemis Intelligent Power, the Digital Displacement Pump uses The fast acting valves and controller allow for high bandwidth control of pump output. The ability to use only the cylinders required to meet the load results in a pump with an efficiency of greater than 90% over most of the operating range. a platform to invent new architectures to capitalise on the capabilities of digital pumps. With inherent digital control, set points and operating parameters can be remotely monitored and controlled to optimise performance. The pump is able to create real time data about the state of the hydraulic system. Already a number of industries are adopting this new approach and utilising digital hydraulics to explore the savings and new features Digital Displacement can bring. In industry, it is ideally suited to applications with wide pressure and flow requirements including injection moulding, water jet cutting and hydraulic power units. The industries of tomorrow will continue to evolve and Digital Displacement technology will be a core component of the smart machines of Industry 4.0 and beyond. www.artemisip.com Issue 37 PECM 131
