A method of operation of a filling system for powerful hydraulic press by filling working cylinders by low-pressure liquid supplied from intermediate accumulators connected with a filling tank under action of pressure difference between the working cylinder and filling tank as a result of displacement of a movable cross downward. Filling the working cylinders is made from intermediate accumulators fed by a centrifugal pump of low pressure, at inlet of which the working liquid is supplied from the filling tank. |
