A WATER PRESSURE CONTROLL METHOD FOR A ROCK SPLIT WITH NO-VIBRATION CONDITION

摘要

A method for controlling water pressure of a rock split device with no-vibration condition is provided to allow a rubber tube to be applied to the rock split device by using the water pressure. A method for controlling water pressure of a rock split device with no-vibration condition comprises a step of operating a piston by applying oil pressure to one side of the piston. Water is supplied to the other side of the piston by a pump(200) so that an actuating cylinder(170) has a volume the same as that of a tube inflated by the water. When the pressure is applied to one side of the piston by oil pressure, the water filled in the other side of the piston is supplied to a split device to inflate a tube. The split device has a plurality of actuating cylinders(170) connected thereto.
