再生水对园林升降式喷头水力性能的影响（Hydraulic Performance of Pop-up Sprinklers with Reclaimed Sewage Effluent）
升降式喷头 再生水 流量 水力性能
2010/12/28
选取园林喷灌中常用的3种升降式旋转喷头：DPX-HP型喷头、具有记忆功能的DPX-TS型喷头和托罗V-1550型喷头，分别在地下水和再生水条件下运行447h，测定运行前、后的流量-压力关系、喷头水量分布和转动均匀性，并利用单喷头水量分布资料模拟计算组合喷灌均匀系数，以评价再生水对升降式喷头水力性能的影响。结果表明，再生水运行447h后喷头流量降低3.4%~4.7%、射程降低2.7%~9.0%，...
