G30 Steel cut off the hydraulic system design, the principle is the use of hydraulic technology, steel cut in the saw blade to achieve fast forward, working forward, rewind and steel pipe clamp, pine folders and other processes, the entire cutting process automation. Hydraulic system design is mainly based on the hydraulic system of the machine, the hydraulic system than other systems have many advantages, and hydraulic technology to today has been very mature, easy to design, calculation, operation of the system. In the design of the hydraulic system, the first based on available data, bined with the desired objectives, the system demonstration program began, and then determined by calculating the initial parameters of the system, and then select the ponents required for the hydraulic system, then the related check
