| Abstract: | The closed loop control system was formed by using pilot proportional relief valve as control-unit, pressure transducer as feeding back unit, the accurate control of the nozzle entrance pressure was realized, and the numerical model of dynamic characteristic was set up. The operation principle of the control system was introduced, dynamic characteristic of the control system was analyzed. The theoretical analysis result was compared with the experimental result. Practical control precision can be up to 0. 02MPa. |
