微穿孔板消声器是在无产阶级文化大革命中诞生的一项科研成果。这种消声器,不仅消声效果好,而且空气动力性能好,阻力损失小,不怕油雾和水蒸气,能耐高温。 吸声结构与原理 微穿孔板,是在厚度小于1毫米的金属薄板上均匀的穿直径小于1毫米的微孔,穿孔率控制在1～3%的范围内。将微 Micro-perforated plate muffler is a scientific achievement born in the great proletarian cultural revolution. This muffler not only has good anechoic effect, but also has good aerodynamic performance, small resistance loss, no oil mist and water vapor, and high temperature resistance. Sound absorption structure and principle Micro-perforated plate, is a uniform thickness of less than 1 mm on the metal plate to wear a diameter of less than 1 mm of micropores, perforated rate control in the range of 1 to 3%.
