Development of an Electronically Controlled Self Teaching Lift Valve Family
Eneko Goenechea, Bucher Hydraulics AG, Switzerland
Hydraulic lifts, and in particular electronically controlled lift control valves, is one of Bucher Hydraulics most unknown fields of activity. In fact Bucher Hydraulics invented the electronically closed-loop controlled lift valve in the 1970s and since then is the technical leader in this field having developed a wide line of products around its valve family. In 2012 it included diverse sizes, pressure ranges, systems with constant motor speeds as well as inverter driven motors and pumps, energy efficient solutions with hydraulic counterweight and countless individual solutions. The common principle is the electronic closed-loop control between the volumetric flow sensor and the proportional actuator.
Since 2012 Bucher Hydraulics is substituting this valve family by its new generation called iValve. The iValves adjust themselves to their environment using several self-teaching algorithms. Their onboard and cabinet electronic provide flow, pressure and temperature measurement, closed loop control of the solenoid currents and more. This enables self-monitoring, adaption to operating parameters of the individual installation and analysis and logging of additional information concerning itself as well as the attached system.
