Изобретение относитс к способам анализа акустических колебаний в жидкости и может найти применение дл обнаружени кавитации.This invention relates to methods for analyzing acoustic oscillations in a fluid and may be used to detect cavitation.
Известен способ обнаружени кавитации по авт.св. W 446767, заключающийс в том, что возникновение кавитации обнаруживают по вьщеленига пахучего вещества из капсулы, выполненной из некавитационностойкого материала, который разрушаетс под действием кавитации.в исследуемой жидкости. .A known method for detecting cavitation is by auth. W 446767, which means that the occurrence of cavitation is detected by removing an odorous substance from a capsule made of a non-cavitationally resistant material that is destroyed by the action of cavitation. In the test liquid. .
Недостатком способа вл етс низка точность определени момента йозникновени кавитации и длительное врем обнаружени кавитации, так как кавитационное разрушение капсулы происходит только с одной наружной стороны.The disadvantage of this method is the low accuracy of determining the moment of cavitation cavitation and the long detection time of cavitation, since cavitation destruction of the capsule occurs only from one outside.
Целью изобретени вл етс уменьшение времени обнарзлкени кавитации и повышение точности определени момента возникновени кавитации.The aim of the invention is to reduce the time of cavitation detection and to increase the accuracy of determining the time of the occurrence of cavitation.
Цель достигаетс тем, что в капсулу из некавитационностойкого материала с пахучим веществом дополнительно ввод т жидкость с порогом кавитации (кавитационной прочностью) исследуемой жидкости. В этом случаеThe goal is achieved by the addition of a liquid with a cavitation threshold (cavitation strength) of the test liquid into the capsule of non-cavitation resistant material with an odorous substance. In this case
-кавитаци возникает одновременно в исследуемой жидкости и в жидкости, наход щейс внутри капсулы с пахучим веществом, и некавитационностойкий материал разрушаетс одновременно с внутренней и наружной сторон.-cavitation occurs simultaneously in the test liquid and in the liquid inside the capsule with the odorous substance, and the non-cavitation-resistant material is destroyed simultaneously from the inside and outside.
Способ дл обнаружени кавитации в воде осуществл ют следующим образом .The method for detecting cavitation in water is carried out as follows.
Некавитационностойкий образец, изготовленный в виде капсулы из алюминиевой фольги толщиной 20 мкм, Заполненный пахучим веществом, например бензином, и жидкостью с порогом ,возникновени кавитации как и у воды например тоже водой, помещают в исследуемую воду, которую облучают ультразвуковыми колебани ми пор дка 20 кГц увеличиваюцейс мощности . При определенной мощности колебаний в воде возникает кавитаци как снаружи, так и внутри капсулы , так как стенки капсулы дл A non-cavitation-resistant sample, made in the form of a capsule of aluminum foil 20 µm thick, filled with an odorous substance, such as gasoline, and a liquid with a threshold, the occurrence of cavitation, like water, for example, water, is placed in the water under investigation, which is irradiated with ultrasonic vibrations of about 20 kHz. increase power. At a certain power of oscillations in water, cavitation occurs both outside and inside the capsule, since the walls of the capsule for
