    摘要:

    除冰液的加注速度是影响机场除冰作业效率的重要因素。设计了一种面向飞机除冰装备领域的双作用式大流量往复泵,给出了设计原理、主要部件设计计算书及总体设计图。通过建模仿真分析双作用泵的压力流量特性;通过改变活塞间隙的仿真实验得到系统阻尼和流量输出的折中优化方案,并依据仿真得到的最佳参数进行实验,验证仿真分析的合理性。结果表明:根据除冰液的粘度,活塞间隙在3 mm条件下,系统阻尼、流量、脉动到达最优关联,流量输出平稳,验证了设计方案的合理性和可行性。泵在工况压力范围内,输出流量和脉动抑制均达到预期效果,性能超越现有同类除冰加液设备性能,为行业应用和相关设备的设计提供参考。

    Abstract:

    Filling 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 aircraft deicing equipment. We demonstrate the principle, the design drawing and the design calculation 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 output 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 simulation, 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 feasibility 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 deicing equipments. This design provides a reference for the related equipment design and industrial applications.
