Valve Displacement Feedback Control Hydraulic Elevator
Tuesday 1st October 1996
In the hydraulic elevator, the cylinder capacity becomes large and the rope be long in proportion to the elevator stroke. We developed the valve displacement control system that feedbacks the valve displacement to the microcomputer. This system prevents the occurrence of the low frequency vertical vibration, so the elevator can run smoothly even if the hydraulic oil temperature of the pressure change.
