The present invention by this simple and easy to do method at Overhaul site (particularly at the complicated Overhaul site of water supply network), can judge fast and accurately booster water kind, and then formulate fast Rush Repair Scheme, not only avoided the error of artificial judgement, more scene rush to repair has won the valuable time.The valve that the present invention is more traditional and pipeline determining method have shortened that the judgement time is nearly 65%, and the accuracy rate of judgement is increased to 100%, has significantly improved overhaul efficiency, has avoided causing larger impact to producing.The present invention judges that the method for industry water or Living Water booster is simple, efficient, and economic benefit and social benefit are all very remarkable.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
Taking certain smelter as example, the on-the-spot quick-speed first-aid repair method of buried supply pipe booster specifically carries out according to the following steps:
(1) obtaining notifying immediately energy scheduling center to explain the situation after reliable booster message and arriving in booster scene with the fastest time;
(2) arrive behind booster scene, resolute collection booster water sample rapidly, and carry out conductivity detection;
Conventionally, the buried supply pipe booster point of smelter minutes two kinds, one is in the wild, one is to enter user side.Field refers to the position between water system and user's point, generally at open ground buried-pipe laying transfer line.Enter user side and refer to that pipeline enters user's factory building or the position with water spot.
The collection point of booster water sample is selected according to booster point position:
(1) be booster water sampling point if booster point, is got first leakage point of booster point in the wild; If cannot collect booster water sample at first leakage point, according to first leakage point recently for principle is determined collection point.
After booster, due to the shape difference of booster point, if booster point is circular hole dress, leakage point is spot distribution, if booster point is irregular geometrical shape, leakage point is mushroom and distributes.After pipeline bursting particularly service time long pipeline, its leakage point can a more than place, the first leakage point refers to first leak source from inlet valve direction.
(2), if booster point is entering user side, getting booster point is booster water sampling point (distance taking booster point apart from user side building is the shortest be according to) from the nearest leakage point of user; If cannot obtain in this position booster water sample, by with this nearest leakage point recently for principle is determined collection point.
It is relatively little that the booster water sample of above-mentioned selected collection point is affected by booster site environment, and therefore conductivity testing result is more accurate.
In order to ensure the accurate of testing result, also should carry out as follows the collection of booster water sample:
(1) open the sampling bottle that washing and sterilizing seals in advance;
(2) rinse after washing sampling bottle 2-3 time and get booster water sample again at the booster water sampling point booster water that takes a morsel, booster water sample volume is no less than 500ml;
(3) after water sampling, add a cover in time or jump a queue.Can record the sampling time, and sampling is numbered simultaneously;
(4) repeat above-mentioned sampling step, until gathered at least three points of water samples.
Meanwhile, in sampling process, should also be noted that:
Sampling operation personnel's hand should not contact with bottle stopper bottom with sampling bottle inwall with gloves, must keep the clean of hand;
In operating process, carry out the protective measure of sampling bottle, avoid glass bottle collision fragmentation and leak;
Before sampling, sampling bottle washing and sterilizing sealing in advance, is placed in clean environment, must not have any extraneous contamination, in the time that booster occurs, directly takes.
After water sampling is complete, carry out at once at the scene conductivity detection.
(3) booster water sample conductivity detection being obtained is compared with known industrial water purification, the conductivity range of Living Water, judges booster water kind, and then judges booster pipeline.
Conventionally, the conductivity range of smelter industry water purification, Living Water is as follows:
Industrial fresh water: 480us/cm～620us/cm
Industry clean circulating water: 650us/cm～1200us/cm
Living Water: basin, 180us/cm～330us/cm(middle and lower reach of Yangtze River)
Can find out that three differs greatly in number range, this is also that the inventive method is able to detect by on-the-spot booster water sample conductivity a foundation that realizes the judgement of booster water kind.And Site Detection conductivity needed time is shorter, be no more than 5 minutes, and judging nicety rate is up to 100%.
(4) according to the judgement to booster pipeline, close the related valve on water supply line, close respective lines system and rush to repair.In pipeline system valve operation process, should notify relevant pumping station to note monitoring in real time the pressure of relevant tube wire system, adjust in time normal range (NR).
(5) rush to repair complete should report to energy scheduling center, contact recovers normal water supply.
(6) occur after booster, as accurately determined booster water kind and booster pipeline by said method, but temporarily can not stop transport because producing reason system, booster point must be taken emergency measures, adopt and beat anchor ear or add the mode emergency processing that Hough connects, to ensure production.After stopping production, then close respective lines system organization personnel and rush to repair.
Through test, utilize the inventive method, judge fast and accurately booster water kind and implement in time accordingly Rush Repair Scheme at the densely covered Overhaul site of feedwater piping for 9 times, avoided causing larger impact to producing, 3,400,000 yuan of direct economic benefits, indirect economic effect is very huge.
