A New Two Speed Control Values in Series and Changes of Two Work Speeds in the Hydraulic Circuit of Power Sliding Feed Table and Design of Its Control System

On the basis of old hydraulic circuit, the author brings forward a new two speed control values in series and changes of two work speeds in the hydraulic circuit to realize the movement of power sliding feed table, offers the fig of its makeup and principle of work, designs its control system by PLC(FX 2N -32MR),gets characteristic of the new hydraulic circuit and control system. By these, the author presents the PLC's broad prospect of application in the field industrial control.
