The present invention by this simple and easy to do method in Overhaul site (particularly at the complicated Overhaul site of water supply network), booster water kind can be judged fast and accurately, and then rapid development Rush Repair Scheme, not only avoid the artificial error judged, more scene rush to repair has won the valuable time.The valve that the present invention is more traditional and pipeline determining method shorten the judgement time nearly 65%, and the accuracy rate of judgement is increased to 100%, significantly improves overhaul efficiency, avoid and cause larger impact to production.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.
For certain smelter, the on-the-spot quick-speed first-aid repair method of buried supply pipe booster specifically carries out according to the following steps:
(1) after obtaining reliable booster message, notify that energy scheduling center explains the situation and arrives in booster scene with the fastest time immediately;
(2) after arriving booster scene, collection booster water sample resolute rapidly, and carry out conductivity detection;
Usually, the buried supply pipe booster point of smelter minutes two kinds, one is in the wild, and one is entering 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 the factory building of user or the position with water spot.
The collection point of booster water sample is selected according to booster point position:
(1) if first leakage point that booster point, gets booster point is in the wild booster water sampling point; If booster water sample cannot be collected at first leakage point, then according to first leakage point recently for principle determines collection point.
Because the shape of booster point is different after booster, if booster point is circular hole dress, leakage point is spot distribution, if booster point is irregular geometrical shape, leakage point is mushroom distribution.The pipeline that after pipeline bursting, particularly service time is long, its leakage point can a more than place, and the first leakage point refers to first leak source from inlet valve direction.
(2) if booster point is entering user side, getting booster point from the leakage point that user is nearest is booster water sampling point (the shortest in foundation apart from the distance of user side building with booster point); If booster water sample cannot be obtained in this position, by with this nearest leakage point recently for principle determines collection point.
The booster water sample of above-mentioned selected collection point affects relatively little by booster site environment, 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) sampling bottle of washing and sterilizing sealing is in advance opened;
(2) booster water sampling point take a morsel booster water rinse wash sampling bottle 2-3 time after get booster water sample again, booster water sample volume is no less than 500ml;
(3) add a cover in time after water sampling or jump a queue.Can the sampling time be recorded simultaneously, and sampling is numbered;
(4) above-mentioned sampling step is repeated, until gathered at least three points of water samples.
Meanwhile, should also be noted that in sampling process:
The hand of sampling operation personnel and gloves not should with sampling bottle inwall and bottle stopper lower contacts, the clean of hand must be kept;
Carry out the protective measure of sampling bottle in operation, avoid glass body collide broken and leak;
Before sampling, sampling bottle must washing and sterilizing seal in advance, is placed in clean environment, must not has any extraneous contamination, directly take when booster occurs.
Conductivity detection is carried out at once at the scene after water sampling is complete.
(3) booster water sample conductivity detection obtained, compared with the conductivity range of known industrial water purification, Living Water, judges booster water kind, and then judges booster pipeline.
Usually, 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 the foundation realizing booster water kind and judge.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 that relevant pumping station notes monitoring in real time the pressure of relevant tube wire system, adjust to normal range (NR) in time.
(5) rush to repair complete should report to energy scheduling center, contact recovers normal water supply.
(6) after there is booster, as accurately determined booster water kind and booster pipeline by said method, but temporarily can not stop transport because producing reason system, then 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, the Overhaul site gathered at feedwater piping for 9 times is judged booster water kind fast and accurately and implements Rush Repair Scheme in time accordingly, avoids and causes larger impact to production, direct economic benefit 3,400,000 yuan, indirect economic effect is very huge.
In addition to the implementation, the present invention can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
