In view of the insufficiency of the current supply circuit of the double hydraulic pump of the machine slide table,the optimal design of the oil supply circuit of the double hydraulic pump is carried out.This paper introduces the working flow and deficiency of the existing two speed regulating valve in the supply circuit of the double hydraulic pump,and emphatically explains the principle,composition and characteristics of the optimized series speed regulating valve in the double hydraulic pump oil supply circuit.At last,taking the oil supply circuit of double hydraulic pump of machine tool slide table as an example,the experiment results show that the PLC and the series speed regulating valve can be used in the double hydraulic pump loop system to control the oil supply circuit of the double hydraulic pump of the sliding table by using the PLC and the series type speed regulating valve.
