Study Of The Electric And Hydraulic Control System Of The C45230B-1 Type Oil Hydraulic Press

Along with the fast development in industry automatic control, Automatic control become into the key of each kind of electric appliance equipment。This topic origins the C45230B-1 hydraulic press by ruan ci plant of ling zi coal mine and mechanical factory of zi chuan union development. This project is aimed at studying and optimizing the design of the electric and hydraulic systems of the C45230B-1 typed oil Hydraulic press, by learning from both the domestic and international advanced techniques and together with the practical situations. to improve the quality and quantity of the industry production. In electric system, the advanced digital products replace the traditional analogous ones. The Programmable Coctroller (PLC) and the circuit now control the system. The communication adopts the RS422 and RS-232C cards. Many new functions have been realized, such as the alarm may be sent out through the sound and the LCD displays in Chinese, and the fault may be alarmed. The hydraulic system is an open loop. the vane pump and the ram pump driven by a double output shaft electrical machinery ,produce two groups pressures oils to the upper cylinder, the under cylinder, the fluctuation cylinder and the cylinder return route. And in detail introduced on the cylinder return route and under the cylinder return route improvement program。After improvement hydraulic press machine, Electrical and the hydraulic control system is more reasonable and reliable, Achieves the automatic control completely, Reduced the equipment failure rate and the maintenance time greatly, Enhanced the production efficiencyThe oil Hydraulic press which the electrical and hydraulic systems are more reasonable and dependable, have totally reanched automaticalled, and the break down faule rate of the equipments and maintain time consumedly reduced.But it have improved production time greatly.
