The hydraulic machine host part includes a hydraulic urn, horizontal beam and sign pillar and Chong liquid device etc. The hydraulic mobile dint organization constitutes to from the fuel tank, high pressure pump, the control system, electric motor, pressure valve, and direction valve...etc..The whole production line will adopt an automation control system and pass the conversion that pump, compressor and oil urn, air cylinder, various valve etc. carries out energy, regulate and transport and complete various circulation that the craft acts. The series hydraulic's machine tool contains independent power organization and electricity system, and adopt to press button a concentration control, can carry out to move with auto two kinds of operate a way. The production line structure's tightly packed acts intelligent credibility, the speed is quick, can consume small, the noise is low, pressure and route of travel can at stipulate of arbitrarily regulate inside the scope, operate in brief. In this design, pass to check a great deal of cultural heritage data, designed the electric power control of hydraulic machine and machine hand system, drew up electric circuit principle diagram, and t
