Abstract

FIELD: mechanical engineering; devices for suppression of noise in hydraulic and air systems. SUBSTANCE: device is provided with silencer used as prototype which is made in form of perforated envelope with high coefficient of perforation terminating in rubber insert having taper chambers charged with air; this insert rests against watertight blank. EFFECT: enhanced acoustic efficiency of noise suppression; dampening of vibrations, extended field of application due to reduction of vibratory energy of hydrodynamic noise at increased total acoustic resistance of device.

Изобретение относится к области машиностроения, а более конкретно - к устройствам снижения шума гидравлических и воздушных систем. Для достижения акустической эффективности снижения шумоизлучения, ослабления вибраций, расширения области применения, основанных на снижении колебательной энергии гидродинамического шума и вибрации при увеличении полного акустического сопротивления устройства, предлагаемое ОУС ГШ выполнено таким образом, что широкая часть глушителя выполнена в виде перфорированной оболочки с большим коэффициентом перфорации, оканчивающейся вставкой из резины, имеющей конические полости, заполненные воздухом, опирающейся на герметичную водонепроницаемую заглушку. Предлагаемое устройство имеет прочное исполнение.The invention relates to the field of engineering, and more specifically to a device for reducing the noise of hydraulic and air systems. To achieve acoustic efficiency in reducing noise, attenuating vibrations, and expanding the field of application based on reducing the vibrational energy of hydrodynamic noise and vibration while increasing the total acoustic impedance of the device, the proposed GUS GSH is designed in such a way that the wide part of the silencer is made in the form of a perforated shell with a large perforation coefficient ending with a rubber insert having conical cavities filled with air, supported by an airtight waterproof face-off stub. The proposed device has a robust design.
