dritape
Examples
- A new type paving equipment for drip irrigation belt
一种滴灌带铺设装置 - Plastic equipment for water saving irrigation - drip tape with labyrinth on one side
塑料节水灌溉器材单翼迷宫式滴灌带 - With the in - built drip irrigation belt and thin wall chip irrigation belt taken as examples , the flow rate distribution and hydraulic losses of drippers along capillary tubes at different inlet pressures were measured under the conditions of horizontal slope and slope gradients of 0 . 5 % and 1 % , then the uniformity of capillary tubes was calculated at different slope gradients and pressures in consideration of the manufacture deviation of drippers
摘要以内镶式滴灌带和薄壁滴灌带为研究对象，测定了平坡、 0 . 5 %坡度和1 %坡度时，不同入口压力下滴头沿毛管的流量分布和水力损失，并结合滴头的制造偏差，计算得出不同坡度和压力条件下滴灌毛管的均匀度。 - The degree of consistency change of sprinkler head and the o 8mm depression drip pipe with the change of pressure has been tested . the main conclusion of this study has been produced as follows : ( 1 ) the theory will be correct and notable benefit will be obtained through the utilization of the frequency changer in tube - well irrigation , spray irrigation and drip irrigation . ( 2 ) some energy saving effect of the frequency changer utilization in tube - well irrigation , spray irrigation and drip irrigation will be produced , 37
本项目的研究内容主要包括变频调速装置在管灌、微喷以及大棚滴灌中的节能效果、变频调速装置对微喷和大棚滴灌均匀度的影响以及变频调速装置在管灌中进行“恒量变压”变频运行试验等，同时，对微喷头与中smm低压插入式滴灌带的灌溉均匀度随压力变化情况进行一r试验研究。 - Abstract : problems caused in designing and management including configuring regulating devices , deciding spaces of the last pipelines , and working - out irrigation scheme in reason using drip irrigation in green houses and in covered lands are raising in recent years , theose not only affect benefits but also result in failing of projects
文摘:近几年来温室、大棚种植蔬菜采用滴灌技术的越来越多，但有些工程无论设计上、管理上都存在一些问题，包括调压设备的合理配置，按土壤、作物、灌水器及滴灌总水量合理确定毛管(或滴灌带)的间距，以及按大棚蔬菜的耗水特性合理确定灌溉制度等，上述各项确定的不合理，不但直接影响效益，严重时可导致工程失败，值得重视。
