Modeling of Hydraulic Load-reacting Proportional Regulating Speed Control System in Comb Cooler

In this paper,the mathematic model of hydraulic load-reacting proportional Regulating Speed Control System in Comb Cooler is made out based on the analyses of every parts constitute and work principle,combining with hydraulic servo control method and hydraulic proportional control method,a mathematic model of the proportional speed control system is worked out and is simplified under some special condition.This model can be applied in production.This model includes four parts,every part of model has three equations.Compared with the hydraulic servo control system of this model,compared to the usual hydraulic servo control system one more reactivity circle is added on.This new part can be made the out-put of the system to reach the require mens of the control.
