| 摘 要： | 结合山西信联集团实业有限公司11CP45型水力驱动自行式喷灌机其中排水付喷嘴的研制，对喷嘴的设计理论进行了研究。包括圆柱形外管嘴自由出流理论分析以及其它常用形状管嘴自由出流特性分析。更换设计了收缩形外管嘴，并利用其压力水缸排水压力，增加了射流装置。经测试计算，水力损失系数减小，流速系数增加，喷嘴流量增加了8%，射程增加了5%，效果十分显著。

| Abstract: | Combine with the research of accessory nozzle of Model 11CP45 sprinkling machine of hydraulic and propeller by oneself made by Shanxi Shineland Group Co., Ltd., the theory analyse of freedom spray of the column and common outside pipe nozzle is studied. The contractive nozzle is designed and efflux device is increased. Through testing calculating, water loses coefficient reduces, and velocity of flow coefficient increases. The flow of the nozzle is increased by 8%.The range is increased by 5%.The result is remarkable. |
