闭式旋转型雨淋喷头的试验研究

Experimental research on closed rotating sprinkler

介绍闭式旋转型雨淋喷头的结构和工作原理。通过动态热性能试验验证闭式旋转型雨淋喷头玻璃球热反应灵敏度,进行了下垂安装方式两个高度的布水性能试验,通过木垛火灭火试验和不同工作压力的转速试验检验其灭火控制性能,并在0.2 MPa的工作压力下试验连续喷水性能。试验结果表明:闭式旋转型雨淋喷头结构设计利于热传递,具有良好的动态热性能和布水均匀性,且达到轻危险级洒水密度要求,工作稳定可靠。

The structure and working principle of closed rotating sprinkler were introduced.The dynamic thermal performance experiment was carried out to test the reacting sensitivity of closed rotating sprinkler glass ball.The water distribution performance was examined in two heights of sagged installation.The fire extinguishing performance was inspected by wood crib fire extinguish and rotating speed test under different working pressure.The continuous sprinkle performance was examined under the pressure of 0.2 MPa.Test results showed that,the structure design of closed rotating sprinkler benefits the thermal transportation;the sprinkler has well dynamic thermal and water distribution performance;the sprinkler density reaches the light hazard class requirement;the function is steady and reliable.
