摘要
植保机械用容积式泵主要用于经济林木和大田作物的药物喷洒,也可用于日常清洗及卫生消毒等领域。基于行业发展和检测能力提升的要求,研制具备较高自动化和智能化水平的工作性能测试系统已成为必然。容积式泵工作性能指标包括容积效率和总效率,是设计测试系统的依据和目的。测试系统主要设计内容包括具备空间多自由度的通用安装平台、高精度的质量法流量计量装置及采用传感器和计算机技术的控制系统,并给出测试系统中工作性能和拟合曲线数学模型。
The positive displacement pump used in crop protection equipment, is mainly used for drug spraying of e- conomic trees and field crops, and also for areas such as daily cleaning, sanitation and disinfection. Based on the re- quirements of industrial development and enhancing testing capabilities, it is inevitable to design a performance tes- ting system with higher level of automation and intelligence. The positive displacement pump performance indicators, including volumetric efficiency and overall efficiency, are the basis for the design of performance testing system. The main design includes a universal mounting platform with multi-degrees of freedom, a high-precision flow measurement device using weighting method and a control system with technology of sensor and computer, and the mathematical model of performance and fitting curve used in the performance testing system.
