Embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the invention will be further described:
The disposable method for detecting of a kind of horizontal water-tube cooler many places leakage point, connect a liquid level observation pipe in the tube bank of the horizontal water-tube cooler bottom, liquid level observation pipe can be directly and bottom tube bank pick out, for horizontal water-tube cooler damage minimum, can restrain on the water inlet pipe communicating arm is being set with the bottom, connect liquid level observation pipe by arm, liquid level observation pipe extends to the high level tube bank of horizontal water-tube cooler, can be vertical, (vertical scale need be set) that can be slightly oblique, it can be stereoplasm tube, can be flexible pipe (need by supporter supports), as long as the high liquid level (HLL) that liquid level observation pipe can reach be not less than horizontal water-tube cooler the superiors' tube bank and can be directly or by the variation of servicing unit observation liquid level, recorded, make water can be full of each layer of tube bank of horizontal water-tube cooler and liquid level observation pipe, liquid level observation pipe liquid level reaches the highest, can in the time of cooling water, close the valve logical with tube bank below the superiors tube bank of horizontal water-tube cooler, except the liquid level observation pipe mouth of pipe, a liquid level contacting with air is at least stayed on top, if liquid level observation pipe liquid level does not reach the highest, add water by liquid level observation pipe port again, also the superiors' pipe that can horizontal water-tube cooler following with the logical valve closing of tube bank after manage a plane by liquid level observation pipe port or other and the superiors of horizontal water-tube cooler opening to be filled to liquid level the highest, liquid level observation pipe liquid level reach the highest after, observe the SEA LEVEL VARIATION of liquid level observation pipe, water level declines and shows that horizontal water-tube cooler tube bank has leakage, records at set intervals elapsed time t and corresponding level value h until water level no longer reduces, using the t value of record and corresponding h value as coordinate points, i.e. point (t, h) or (h, t) at rectangular coordinate system described point, then these points are linked to be to a curve, on curve, occur flex point, the h value of flex point place coordinate is corresponding with leakage point place height.
Specifically as shown in Figure 1, this horizontal water-tube cooler is provided with upper hose 6, return pipe 4, upper hose 6 is provided with upper hose valve 7, return pipe 4 is provided with return pipe draw-off valve 5 and backwater pipe valve 11, upper hose 6 is provided with sluicing arm 10, sluicing arm 10 is provided with upper hose draw-off valve 8, snorkel 12 is established on return pipe 4 tops, snorkel 12 is provided with Ventilating duct valve 3, snorkel 12 mouth of pipe height are not less than the superiors' tube bank of horizontal water-tube cooler, described liquid level observation pipe is connected on sluicing arm 10 mouth of pipe places, in order to record the changing value of liquid level, liquid level observation pipe is transparent pipe 9 and indicates scale value, stop into horizontal water-tube cooler hot gas, close return pipe draw-off valve 5, backwater pipe valve 11, upper hose valve 7, open upper hose draw-off valve 8, Ventilating duct valve 3, the superiors that chilled water to the liquid level of being left by snorkel 12 upper orifice or transparent pipe 9 upper orifice water fillings or utilization is not less than horizontal water-tube cooler restrain, observe the interior liquid level variation of transparent pipe 9 and constantly record level value and corresponding time value, until level stability, taking time value t as transverse axis, level value h is longitudinal axis described point, each point is linked to be to a curve, the ordinate value of point of inflexion on a curve is corresponding with the height of leakage point.
Described transparent pipe 9 is lucite pipe or transparent glass tube, is bundled on support bar 13 or is sling by lifting rope, if frangible glass tube also need be by supporter supports if transparent pipe 9 is soft Guan Zexu.If when soft pipe, may there is bending in pipe, so also indicate scale value on support bar 13 surfaces, can set it as the scale of SEA LEVEL VARIATION in pipe.
On liquid level tube 9 or support bar, 13 scale value can increase from top to bottom, also can increase from lower to upper, for convenient, make fluid value consistent with leak point height, it is corresponding horizontal water-tube cooler bottom tube bank at zero point, the superiors' tube bank of the corresponding horizontal water-tube cooler of high point, the coordinate figure of flex point level value h is exactly the height value of leakage point like this.
Can also survey with additive method the variation of liquid level, as surveyed with tank gage, complete observed and recorded on ground, remove from workman climb measure danger, better way is that the signal that the device of surveying liquid level is sent is connected into computing machine, coordinate corresponding software by the computing machine figure that plots, provide doubtful leak point height, realize automatic measurement.
The party's ratio juris is: water has been full of horizontal water-tube cooler tube bank and liquid level observation pipe, other valves close, the water surface contacts with air, if tube bank has leakage point, due to the existence of hydraulic pressure, water can flow out from leakage point, cause liquid level to decline, liquid level decline hydraulic pressure reduces gradually, liquid level fall off rate also reduces, but change not obvious, until the leakage point of the tube bank of liquid level and certain one deck maintains an equal level, this leakage point tube bank is no longer leaked, owing to having lacked this leakage point, liquid level fall off rate there will be a unexpected reduction, what now on curve map, show is one " flex point ", this puts the height that corresponding level value is exactly leakage point, so just find out easily this leakage point.
For being more readily understood, provide a curve map example, as shown in Figure 2, curve overall trend declines, curve peak starts to decline, rate of curve reduces slowly, be bordering on straight line, in curve decline process there is a some A that the range of decrease is larger in slope, in example, there is A, B, C, D, E, F is totally 6 points that slope changes suddenly, during to F point, slope reduces to zero, liquid level remains unchanged, be that F point height has not had leakage point below, these 6 points i.e. " flex point ", the value of corresponding ordinate is exactly level value, what level value was corresponding is exactly the height of leakage point.
