Oscillation damping system`s pressure balancing method for construction machine, involves processing electronic signal of pressure sensor with signal of speed sensor such that valves are controlled over relays of controller

摘要

The method involves measuring pressure difference between a pressure accumulator side and a canceling side using a pressure sensor, and amplifying an electronic signal of the difference. The signal is provided as a switching signal into a differential pressure switch. The pressure on the accumulator side is adjusted to the canceling pressure by a valve and the connection of a pressure accumulator is carried out after the adjustment. The electronic signal of the pressure sensor is processed with the signal of a speed sensor such that valves are controlled over relays of a controller.
