虹吸系统介绍

1、Geberit Pluvia 吉博力虹吸式屋面雨水排放系统,GEBERIT the system supplier,吉博力 系统供应商,Pluvia System,提示： 首先强调完整的水管理系统的概念，而不是很快地将该页跳过,高效，安全的屋面雨水排放系统(Efficiency and safe roof drainage system,空气 (air,水 (Water,传统重力流状态 (Traditional gravity drainage,虹吸流状态 Syphonic drainage,只有水 (Only water,管径减小 Decrease of pipe diameter,流量增加

2、 (Flow volume increase,满流排水更高效 (More efficiency if the pipe is full of water,负压的抽吸作用，使流速更快 (Bigger velocity under negative pressure,提示： 为什么管径减小，流量反而增加？ 因为管道呈满流状态，且流速加快,虹吸水力原理 Syphonic theory,折点,HT：提供虹吸式雨水的动力 Engine of the Pluvia system HT 10m，水头损失最多为1000mbar Max. possible pressure loss is 1000mbar,建

3、筑物的总高度是产生虹吸的原动力，根据不同管径，建筑的最小高度不能低于3-5米 (The total height of building is the original dynamic to create syphonic. According to different pipe diameter, the Min. height of building should not lower than 3-5 m,提示： 强调虹吸的总能量来自建筑的高度。 雨水斗下来1米的高度也是必须的，否则水将没有动能在水平管里流动,形成虹吸的关键 (Key point of syphonic drainage,

4、形成虹吸的关键在于管道内没有空气进入 (The key point is no air should enter the pipe,气旋会将空气带入管道内 (Air whirl will bring air into the pipe,形成虹吸的关键 Key point of syphonic,Pluvia Outlet 最终解决(Final solution,反气旋强制虹吸挡板 Anti-vortex plate,当斗前汇水深度达到一定的高度，就会产生虹吸， 并且这一深度是固定的，可控的。 A certain height of water depth will create syphoni

5、c. The height is fixed and controllable,提示： 强调斗前水深稳定可控，因为我们的竞争对手都做不到。 当达到工作暴雨强度时，我们的斗前水深是稳定不变的，说明流量相当稳定。而竞争对手的斗前水深是不稳定的，说明流量也不稳定，对系统的伤害是很大的。 另外当暴雨强度超出工作范围时，我们的斗前水深会一下子上深，说明系统已饱和，不再能排更多的水。只能通过溢流口排水。但竞争对手的系统却还能排更多的水，说明管道中的流速在不断地增加，这样会使管道超出它的疲劳极限，从而大大降低系统的寿命,虹吸形成的过程 (The progress of syphonic formation,

6、刚开始下雨，系统仍处于重力流状态，水平管内水流速度较慢，水位逐渐上升。 In the beginning of rain, the system is in gravity states, the velocity in horizontal pipe is very slow, water level is increasing gradually,虹吸形成的过程 The progress of syphonic formation,随着屋面水位的不断上升，当达到计算斗前水深要求时，系统产生虹吸，排水量增大。当斗前水位回落至标准以下，系统又将回复到重力状态。 因此在降雨初期，虹吸流与重力流总

7、是交替产生。 Along with the increase of water level, the system will create syphonic effect when the calculated water depth is reached, and drainage capacity will increase. While the system will go back to gravity states when the water level drop down below the calculation depth. Thus during the initial p

8、eriod of raining, syphonic flow and gravity flow always appear alternatively,虹吸形成的过程 The progress of syphonic formed,随着降雨量的不断增加，管道内逐渐形成稳定的虹吸状态 Along with the increase of rainfall, stable syphonic states are formed gradually,最大负压点 Max. negative pressure point,与传统的比较 Compare with conventional system,传

9、统重力式 Conventional gravity system,虹吸式 Syphonic system,管径大，需1-3%的坡度 Big pipe diameter and slope of 1-3% required,管径小，无需坡度，美观节省空间 Small pipe diameter, no need of slope, save space and more design freedom,更少的材料 更少的地面开挖工作 Less downpipes, less digging work,材料多，安装复杂 More downpipes, complicated ground work,

10、虹吸在什么时候产生 When the syphonic create,在降雨之初，虹吸流与重力流始终处于交替状态 In the beginning of rain, syphonic flow and gravity flow always change by turn,没有一种系统可以在整个降雨过程中始终达到虹吸状态 No system can be syphonic states through the whole raining period,但是吉博力能更加容易达到并控制这种状态 But Geberit can easily reach and control syphonic sta
