The filling model of hydraulic system for potential energy recovery belongs to the key research field of fluid and control.Discuss the characteristics of continuous oil filling and intermittent oil filling mode,analyzes the working principle of potential energy recovery closed hydraulic system,based on the leakage characteristics of different working environment filling model,namely based on the change of tank level filling model,based on the working temperature change of oil filling model three gap filling model,and derived the mathematical expression of three oil filling model respectively.Intermittent oil filling model can fill the closed hydraulic system according to the system needs,and can simplify the system configuration,increase the reliability of the system,and more energy saving.Among them,the oil filling model based on the working temperature change has the most extensive applicability because it fully considers the temperature change characteristics of the accumulator.
