Cutting energy costs in hydraulic systems by up to 80%.
Hydrotech is respected for their innovative ideas and technical expertise, and also the development of Energy Efficient Hydraulics, for example, the variable-speed pump which drives supply for only the power a process requires, cutting energy costs in hydraulic systems by up to 80%.
Variable-speed pump drives aren’t warranted for every hydraulic system.
But engineers should consider them whenever a machine cycle has fluctuating flows. “Intelligent” servodrives sense demand and regulate speed and, thus, power consumption of the electric motors. The more time a machine spends running under partial-load conditions, the greater the potential energy savings.
Applications where variable-speed pump drive offer substantial energy savings include: • Machine tools • Plastics-processing machines • Die casting • Presses • Woodworking and Papermaking.
Traditional hydraulics run at a constant speed and generate flow without regard to the actual power needed by a machine.
• Variable speed electric drives rotate pumps at their most efficient speed to supply only the hydraulic power a process requires.
• Engineers should consider using variable speed pump drives whenever a machine cycle has fluctuating flows.
