中文摘要：

基于功能设计方法,设计了一套混合动力平衡式泡沫比例混合装置,即一柴一电平衡式泡沫比例混合装置,并根据国家标准GB20031—2005《泡沫灭火系统及部件通用技术条件》[1]进行了相关实验。通过试验数据的分析与处理,试验结果表明,主系统（电动机驱动）与备用系统（柴油机驱动）的压力损失试验、泡沫混合比试验均达到国标要求,系统运行良好。

英文摘要：

A balanced foam proportional unit with hybrid power was designed on the basis of functional design, which had a diesel drive and an electromotor drive. Related experiments were carried out according to GB20031-2005 ＂foam extinguishing system and components of general technical conditions＂. The results can meet the demands of GB20031-2005 on the basis of experiments data including the pressure loss test of master system （motor drive） and back-up system （diesel engine）, the foam mixing ratio test, and the reliability test. The system can work well.
