Dug installed for the Hydraulic System analysis and clear dug installed for the Hydraulic System design requirements. Dig the capacity of the hydraulic system the dug installed component, which is digging capacity of the working cycle of the power system, the performance advantages and disadvantages of the hydraulic system to determine the level of digging installed performance. The capacity development of hydraulic technology development directly related to digging, digging capacity and hydraulic system design are inseparable, the two promote each other. The high-pressure technology is a modern dig installed technology base, digging capacity development and promote the improvement of the hydraulic technology. Digging capacity of the hydraulic system, many of the advanced technology of the hydraulic drive are reflected in the dug installed, such as LUDV system widely used in digging the installation of the hydraulic system. As technology advances, digging capacity of the hydraulic sys
