the outside carry ability will with carry out the increment of the ponent quantity but in the system, be a the pedestal liquid to press the pump toward a performance ponent to provide the oil, discharge that enters each performance ponent be just the liquid press the pump exportation discharge of a allotment of the discharge with each last the outside carries the lotus of dissimilarity but variety, enter first outside carry the smaller performance ponent of lotus, only be each performance ponent up outside carry the lotus equality, then can carry out to act at the same time.The whole liquid presses to spread the good and bad of move the machine function, mainly being decided by the quality that the liquid presses the system function, including the ponent quantity good and bad use, basic back track whether fitting etc..The quality of the system function, in addition to satisfying to use the function to request, should make use of, adjust from the efficiency, power that the liquid press the system soon scope and tiny adjust characteristic, vibration and voice of noises and the gearing of the systems and adjust to try whether convenient credibility etc. carry on.The modern engineering machine almost adopts the liquid to press the system, and bine with electro
