Abstract
Hydraulic system is powered motor basis,the use of hydraulic pump will translate into pressure on the mechanical energy, promote the hydraulic oil.Through various control valves to change the flow of hydraulic oil, thus promoting the hydraulic cylinders made of different itinerary,the movements in different directions.All kinds of different equipment to complete the actions required.This paper introduced the craftwork calculation and the main technical features of the machine hydraulic system.The small high -pressure flow gear pumps and the high-pressure large flux and variable pump used by the supplied oil circuit can effectively improved the efficiency of the production equipment;the designed timing loop held a high control accuracy and response speed;the pressure-balanced valve used by the pressure loop could effectively solve the balance stability question of the erect dynamical head which was declined rapidly. The excellent design and manufacture capability could satisfy the production demand for high efficiency and robotization of users automated production efficiency.
