第二部分PB40摆片式喷头 PB40摆片式喷头是一种新型喷头,采用摆片式回转机构,能作全圆或任意角度的扇形自动喷灌,结构新颖,性能较好,运转比较可靠. 一、性能 PB40喷头采用双嘴结构,性能见表.与单嘴喷头比较,工作压力、喷水量相同时,可得到更好的雾化指标.雨滴直径小于2.5毫米,H/d值达3120.一般说来,雾化指标高了,射程则受影响,但PB 40喷头在工作压力、喷水量与单嘴摇臂喷头基本相同的情
The second part of the PB40 pendulum nozzle PB40 pendulum nozzle is a new type of nozzle, the use of swing-type rotary mechanism for all round or any angle fan-shaped automatic sprinkler, novel structure, better performance, more reliable operation. Performance PB40 nozzle with double-mouth structure, the performance shown in Table Single-nozzle nozzle, the working pressure, the same amount of water spray, you can get better atomization index raindrop diameter of less than 2.5 mm, H / d value of 3120. In general, high atomization index, the range is affected, but the PB 40 nozzle pressure at work, the amount of water spray and single-nozzle rocker nozzle basically the same situation
