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%，...
自吸网式过滤器过滤时间与自清洗时间变化规律分析（Analysis of Filtering Time and Sewage Time for Automatic Suction Screen Filter）
微灌 过滤器 过滤时间
2010/12/28
微灌用过滤器是保证整个微灌系统正常运行的核心过滤设备，开发具有自清洗功能的过滤设备则是研究的重点。在对自吸网式过滤器进行水力性能试验的基础上，分析了自吸网式过滤器过滤时间的变化规律，表明过滤时间的变化并非呈线性规律；分析了自清洗时间的影响因素，指出自清洗时间并不是恒定不变的，而是在其他参数固定时与进水含沙量S0呈反比关系。
