Servo-Variable Pump Drives Offer Energy Efficiency & Control

摘要

Sytronix servo-variable pump drives from Bosch Rexroth combine servo technology with hydraulic pump control. Variable-speed pump drive technology chat matches pressure supply to demand is creating the ability for energy-efficient hydraulics to produce energy savings in the range of 30 to 80 percent. New Sytronix technology from Bosch Rexroth is targeting these applications with a scalable range of variable speed pump drives. A frequency-controlled pump drive (FcP 5000) is the base variant suitable for use in constant pressure systems. The DFEn 5000 control system is designed for high power ranges using an axial piston variable displacement pump driven by an asynchronous standard motor and frequency inverter.
