Claims (4)

1. Способ определения места утечки из трубопровода по интервалу времени между зондирующей и отраженной гидроударными волнами, отличающийся тем, что гидроударные волны посылают с амплитудой 50-6,5•105 Па и частотой колебаний в диапазоне от 0,004 Гц до 500 кГц, а расстояние до места утечки определяют с помощью стандартного снаряда, от которого поступает сигнал, отраженной гидроударной волны, по его местонахождению.1. The method of determining the place of leakage from the pipeline by the time interval between the probe and reflected shock waves, characterized in that the shock waves are sent with an amplitude of 50-6.5 • 10 5 Pa and an oscillation frequency in the range from 0.004 Hz to 500 kHz, and the distance to the place of leakage is determined using a standard projectile, from which a signal from the reflected hydroshock wave is received, at its location. 2. Способ определения места утечки жидкости из трубопровода по п. 1, отличающийся тем, что расстояние до места утечки определяют по формуле
X = τ•v/2,
где Х - расстояние до места утечки;
τ - время прохождения волны от источника до приемника;
v - скорость волны.2. A method for determining the location of a fluid leak from a pipeline according to claim 1, characterized in that the distance to the leak is determined by the formula
X = τ • v / 2,
where X is the distance to the leak;
τ is the wave propagation time from the source to the receiver;
v is the wave velocity. 3. Способ определения места утечки жидкости из трубопровода по п. 1, отличающийся тем, что характер утечки определяют по изменению амплитудно-частотной и фазо-частотной характеристик отраженного сигнала волнового поля. 3. The method for determining the place of liquid leakage from the pipeline according to claim 1, characterized in that the nature of the leak is determined by the change in the amplitude-frequency and phase-frequency characteristics of the reflected wave field signal. 4. Способ определения места утечки жидкости из трубопровода по любому из пп. 1-3, отличающийся тем, что в качестве снаряда для отражения гидроударной волны используют стандартные скребки или разделители. 4. The method of determining the place of leakage of liquid from the pipeline according to any one of paragraphs. 1-3, characterized in that as a projectile to reflect the shock wave using standard scrapers or dividers.
