英文摘要：

Fil ing speed of deicing fluid is an important factor that affects the efficiency of airport deicing operation.In this paper,we design a double-acting large flow reciprocating pump for air-craft deicing equipment.We demonstrate the principle,the design drawing and the design calcu-lation of key components.The pressure-flow characteristics of double-acting pump are analyzed through modeling and simulation methods;the optimal program of system damping and flow out-put are obtained by the simulation experiment of changing piston clearance.We implement a practical experimental analysis,which is based on the optimal parameters obtained from the sim-ulation,to test the rationality of the simulation experiment.The result is shown that,according to the viscosity of the deicing fluid,the system damping,flow and pulsation are optimal relevance and the flow steady output when the piston clearance is 3mm.This verifies the rationality and fea-sibility of the design.Within the operating pressure range of the pump,the output flow and ripple suppression achieve the desired effect,and the performance is better than the existing similar de-icing equipments.This design provides a reference for the related equipment design and industri-al applications.
