  • Experimental analysis of energy consumption of piezo actuators used in hydraulic switching valve [Elektronski vir]
    Šimic, Marko ; Herakovič, Niko
    This paper presents a four-way digital piezo valve system (4WDPVS) composed of four high-response switching piezo valves. The main part of the new switching valves introduces the piezo actuator ... system (PAS) used instead of conventional solenoids. One of the important aspects in digital hydraulic systems is the use of energy-efficient switching hydraulic valves that assure low switching energy and low holding power consumption in the steady-state open valve state. First, the theoretical background of piezo technology is presented. Second, a detailed description of the new piezoelectric actuator system used in switching valves and four-way digital piezo valve system. The main part presents experimental analysis of the electrical energy consumption of the new piezoelectric actuator system. To validate and compare the electrical switching energy and the holding power consumption, several existing switching valves were used as reference. The results show a huge reduction of electrical energy consumption when using the new PAS for hydraulic switching valve actuation. Especially the holding power consumption in the stationary active state is about 6 times lower compared to other existing hydraulic switching valves controlled by solenoids.
