Description

11ред.иагаеыыи приоор предназначен дл  точнсго определе.ни  течкн 1.1 водопроводных i рубах, например, в тепловых сет х, посредством измерени  звука, издаваемого течью, и дает возможность опредсл5 ть по показанию индикатора ннтексивность течи.11red. Ы е ы и и при предназначен is designed to accurately determine 1.1 water pipelines, for example, in heat networks, by measuring the sound produced by a leak, and makes it possible to determine, according to the indication of the leak index indicator.

В известных приборах, определ ющих место утечки и селективно регистрирующих шум течи посредством измерени  звука, используютс  микрофон, усилитель п индихаJCJp .In the known instruments, which detect the leak and selectively detect the leakage noise by measuring the sound, a microphone, an amplifier and an indium-JJJp amplifier is used.

Предлагаемый гфибор отличаетс  тел, что 3 ЕЬ;Хсдную ие.ль усилите .т , присосд:иненную к обычном} микрофсну , с г,елыо настройки прибо уй на нужную частоту акустических ксхлебаниГ, включаетс  полосный фильтр с переменной наст;юйкой.The proposed gfibor is distinguished by the bodies that 3 ЕЬ; Хсдную и.ль amplify., Prisd: inn to normal microfiche, with r, you can adjust the equipment to the desired frequency of the acoustic X-ray, the band-pass filter with a variable tuner is turned on.

Как видно из схемы прибора, изображенной па чертеже, чувствительный микрофон 1 прикладываетс  к грунту по трассе ревизируемой тепловой сети 6.As can be seen from the diagram of the device shown in pa in the drawing, the sensitive microphone 1 is applied to the ground along the path of the heat network being audited 6.

тока на чувствительный магнитоэлектриче:-кий гальванометр 5. Фильтр 3 необходим дл  отс эильтровывани  посторонних звуков. Это возможно, пото.му что тональность звука, издаваемого течью, значительно отличаетс  от всех обычных шумов (частота , издаваейого течью, лежит в пределах от ЗСОО до 4CGO гц, , то зрем  как наиболее ггрссслзнье ;;з мешающих шумов имеют частоты ниже 1000 гц. lip:: PHGOTO г::;::бор касгр;::зают на частоту течи и передвигают л икрофои по трассе тепловой сети.

Filter 3 is necessary for the extraction of extraneous sounds. This is possible, because the tone of the sound emitted by the leak is significantly different from all ordinary noises (the frequency emitted by the leak is from CEC to 4CGO Hz, then we see as the most difficult noise; -120 Hz . lip :: PHGOTO g ::; :: boron kasgr; :: call in on the frequency of the leak and move the irrigation system along the heating network. Where it is inspected: iggf gives the maximum from CLOLEN: - e. t; n: o,: cst: ; -: gtechki.
