Reducing costs while increasing energy efficiency
We are excited about a newer type of electro-hydraulic actuator with applicability in water/wastewater and hydropower installations. Hybrid Actuator System (HAS), a newly launched product from Parker Hannifin’s cylinder division, is a self-contained linear actuation system that brings electrification to where the work occurs. Here’s the main benefit: By localizing the power source, Parker’s hybrid actuator eliminates the centralized power unit along with its electric motor, pump reservoir, and related valving, but also all the hoses and tubes connecting them to the actuator — dramatically reducing system complexity and simplifying troubleshooting. Instead, it consolidates the entire hydraulic system into a single component integral to the actuator that hooks up to a local control point.
Delivers 3x the power density of a traditional hydraulic system
Hybrid actuation systems have one-third the footprint of a equivalent hydraulic power unit. Compared to a 10 HP hydraulic power unit, which typically occupies 6.6 cubic feet, the HAS 500 occupies just 1.9 cubic feet. The HAS 500 has a 2-1/2″ bore, 1-3/8″ rod, 24″ stroke 4 GPM operating at 3000 PSI.
Saves energy by deploying incrementally as needed
The horespower losses that occur in valve-operated hydraulic systems are significantly reduced in hybrid actuation systems (HAS). In HAS, 72% of input power is available for work, compared to just 47% availability in a traditional hydraulic systems.
For this reason, energy consumption per cycle is significantly lower in hybrid actuation systems.
Features benefit customer’s application
Designers and integrators who employ hybrid actuation systems help their customers reduce energy costs associated with operating their hydraulic systems. Additionally, the end user will have reduced maintenance costs and hours. The components absent in self-contained actuators (electric motor, pump reservoir, hydraulic lines, fittings) no longer require attention. Parker’s HAS units operate for at least 8,000 hours before maintenance is due.
