Deicing fluid filling speed is an important factor affecting the efficiency of deicing airport operations. A double-acting high-flow reciprocating pump designed for the field of aircraft deicing equipment is designed. The design principle, design calculations and design drawings of the main components are given. The pressure-flow characteristics of the double-acting pump were analyzed through modeling and simulation. The compromise optimization scheme of the system damping and the flow output was obtained by changing the piston clearance experiment. The simulation was conducted based on the best parameters obtained from the simulations to verify the rationality of the simulation analysis. The results show that according to the viscosity of deicing fluid, the system damping, the flow and the pulsation reach the optimal correlation under the condition of the piston clearance of 3 mm and the flow output is stable, which proves the rationality and feasibility of the design scheme. Pump in the working pressure range, the output flow and pulsation inhibition are to achieve the desired results, performance than existing similar deicing and dosing equipment performance, for industrial applications and related equipment design reference.
