Pressure Control System for a Hydraulic Lift and Flotation System |
摘要 |
A control system is provided to control the rate of pressure rise in a hydraulic lift and flotation system. When a hydraulic cylinder of the hydraulic lift and flotation system is to be adjusted, the pressure in the hydraulic lift and flotation system has to be increased to a predetermined pressure controlled by a relief valve before the hydraulic cylinder can be operated. The unload valve of the hydraulic lift and flotation system can be closed in a controlled or regulated manner in order to control the rate at which pressure rises in the hydraulic lift and flotation system.
