The main composition of leakage: ba快購sed on the analysis of the composition 理懂of leakage water in 這熱the water balance table 山笑of China Water Associatio新要n, and referring to the le道拿akage rate control cases of many d站對omestic water supply e女房nterprises. Leakage (ra月但te) composition of domestic外海 water supply enterprises includes:
1、Physical leakage: usually mor購哥e, generally accounting for 55-75% of 樂話its leakage;
2、Table (measurement) leakage: relati現暗ve physical leakage l西醫ess, usually accounting for 15-拿麗30% of the leakage;
3、Others: refuse to copy, st劇機eal water, private ta公影keover line, etc., u靜厭sually less about 10-15% of its leakag風南e.
Shanghai Keyontechs leakage cont個件rol management system app費區lies the minimum flow at nigh問輛t, according to the ALR theory, 離看utilizes the Internet of Thin在購gs, and adopts high-end sensing devic說我es (such as A+k electromagnetic w們路ater meter, leakage warning and leakage近長 point positioning system). The leaka分姐ge control system can quickly warn 鐵頻the leakage section after detecting秒商 the leakage area in the 上通zoning metering management. Thi低關s system is a deep in又又tegration of the new generation of in坐用formation technology and wate通制r technology. It fully ex好多plores the value and logical rela業兵tionship of data, realizes t就一he intelligent control, data res市坐ource, precise management and intel化兵ligent decision-making店長 of water business syste務火m, guarantees the safe operat樹朋ion of water facilities, and 了去makes water business operati用靜on more efficient, management more scie朋美ntific and service more quality.腦媽 At the same time, the system ca這生n be compatible with the exi東海sting revenue system, 不們GIS system, SCADA system, hydraulic他上 model and other syste喝也ms of the department習紙 of Water Resources, or in公熱corporated into the compreh下輛ensive information management 廠門platform of the department of金答 Water Resources, to help the厭西 construction of smart water秒風 resources of the Department of W分什ater Resources.
The selection of surface 鐘算is the top priority of leak拿但age control work, is als南玩o the most rapid, direct results o音下f leakage control means. Electromagn飛低etic water meter has the characteristi物近cs of high precision, low 快聽starting flow, small fl煙化ow metering sensitive an術事d accurate, high stability, 見人low power consumption, low i志農nstallation environment requir通們ements, wide flow rate range, hi厭做gh protection level, no pressure l機暗oss, remote monitoring and anti-inter門討ference. It is necessary 兵的to gradually use and replace large-dia能話meter electromagnetic water meters這睡 according to demand, especi影弟ally to manage the leakage contr業煙ol of non-resident users' trad分飛e settlement income and residents' me鐵月ter leakage.
The effect of non-resident慢市 large users' trade settl在靜ement is direct and easy to imp錯跳lement. However, the leak舊熱age management of residential meters a什呢nd water management of public校話 utilities need to be strengthened白醫 in a multi-pronged m雪近anner, including: Th作讀e use of remote examina地信tion form, regular c務線alibration, improve the copy r就書ate, rectify the behavior of pr鄉劇ivate connection and 男日flip, carry out the in讀務vestigation of the natu鄉個re of water use, stre說看ngthen the management o裡又f buried table, promote the fire微生 alarm device, increase the meteri習長ng and supervision of water use wit生中hout table, strengthen我如 the strength of busines如和s inspection and impro答吧ve the management lev近男el of table management, so as to r窗說educe leakage and continuous動風ly reduce the leakage議亮 rate.
Based on DMA partition measuremen友刀t, improve the control leve筆店l of physical leakage of pipe network a亮玩nd shorten the duratio生資n of leakage to reduce physical 多吧leakage; At the same time, reasonabl志吃e pressure management is car就站ried out according to the comprehensiv空大e water supply situation s著討uch as the water supply are微和a topography, pipe netwo內輛rk and water use characteri喝遠stics, so as to reduce the phy什雪sical leakage of the做們 stock and reduce the occur生視rence of pipe explosion and new leakag花離e.
DMA zoning metering management is a sys子校tem engineering involvi從風ng many factors, no matter the thr拿暗ee-level or more fin村亮e zoning metering management, or體美 the implementation of bottom-up or t刀你op-down implementation s遠到teps, should be based on t見關he water supply enterprises劇輛 own situation, or step by step舞林 construction and even selec樹湖tive implementation.
Shanghai Keyontechs has i湖紙mplemented zoning metering舊麗 management of water樂民 supply enterprise experie我南nce data and water leakage 下動detection project data (leaka女器ge point, leakage and pipe ne男筆twork diameter relationship - the視錢 number of leakage points in the di體我strict pipe network acc為頻ounts for about 75% of the tota冷讀l number of leakage po中分ints, leakage water accounts for abo離多ut 61% of the total leakage water站她), leakage points in the district. 睡們The DMA is the most easy to build and舞樹 manage, DMA night minimum flow mo海雨nitoring fluctuation懂物s sensitive, in theory can be 麗生found water leakage time control美術 within 24 hours, the most對數 easy to see the resu海見lts, so DMA construction should 通些be listed as the fir姐的st link of the division measurem費熱ent (in addition to the first div大資ision assessment management purpose) a村著nd the important link of leakage contr內民ol management.
Water difference between productio可理n and sales = free water supp器下ly + physical water 男視leakage + book water lea北湖kage
According to the International Water 西草Association (IWA), the匠雨 analysis and statistics如志 are as follows:
The physical leakage ratio of pipe ne匠書twork is significant: according to可鐵 the analysis table of the p時房roduction and sales difference of 訊車the International Wa化紅ter Association, and refer to th器多e leakage control case年信s of many domestic water supply e些女nterprises. In the le機員akage rate of domestic water supply飛人 enterprises, physical謝技 leakage accounts for relatively la火分rge, generally accoun秒錢ting for 55-75% of the l車低eakage rate, and the ov爸人erflow of water tank and pool accounts校我 for very little, so the con知件trol of physical leakage of體冷 pipe network is the key to leak謝能age control.
Physical leakage control, no mat從笑ter the size of the leak point, 路熱should be a short period of dete北微ction, the necessary par子村tition measurement work and sy村森stem leak detection engineering, do ea門她rly detection early repair, es校紙pecially small leakage 那都point is often not easy to光好 detect, but it causes water leaka道又ge for a long time, the明樹 total amount of water l電民eakage is large, but跳水 is an important factor causing le身器akage.
Efficient leakage contro明美l based on zoning measurement can 爸商quickly warn abnormal樹金 areas and greatly shorte讀那n the time for leakage point書算 discovery. However, accurate posit見地ioning of leakage poi雪在nt still requires professional了說 personnel to use pro道道fessional instruments. P北服rofessional leakage control team and空明 professional technology are t看多he guarantee of leakage 做河control results.
Shanghai Keyontechs 房東has more than 50 prof市生essional leakage cont見白rol personnel, which can condu章拿ct a comprehensive, profess腦的ional and systematic water leakage村線 survey and positioning of the wa又拿ter supply network in a short period市都. In particular, water supply務爸 enterprises without refined zoning m紅呢etering management need short p件也eriod, full coverage and system音問atic water leakage detection work妹草.
In the leakage control work, Shangha習我i Keyontechs can help the wa很說ter supply enterprises to子街 train the actual operation personnel 錯子of leakage detection and e舊坐stablish the leakage con你作trol team, to provide profession銀少al technical support fo車明r the leakage control work of the water如事 department; It can also help water事開 supply enterprises t山問o explore their own 鐵外leakage control mode and system窗影, so as to establish a報兵 professional and sustai放麗nable leakage control platform市明 and mechanism.
