外充气式压缩喷雾器试验研究

Experimental Study of the ExternalInflationTypeCompression Sprayer

外充气式背负压缩喷雾器能彻底地克服传统的背负手动喷雾器的漏药、窜药、配制药液浓度难以掌握、机型陈旧、功能单一的缺陷．一系列的试验证明了外充气式压缩喷雾器的操作性能、喷雾效果与传统喷雾器完全一样，工作寿命比传统喷雾器延长一倍．

The tests show that the externalinflationtype knapsack compression sprayer can overcome the following defects of the traditional knapsack hand sprayer: solution leakage, fluctuations in concentration, obsoleteness of the models and the singleness of function. The tests also show that the externaltype compression sprayer has exactly the same spraying effects as the traditional one while its working life is twice as long.
