style="text-indent:25px">阻抗復合式消聲器組裝時，應先用圓釘將制成的消聲片裝釘成消聲片組，同時用鉚釘將橫隔板與內管分段鉚接好，然后用半圓頭木螺絲將各段內管與消聲片組固定，再將外管與橫隔板、外管與消聲器兩端蓋板、蓋板與內管分別用半沉頭自攻螺絲固定，之后在鉚接兩端法蘭。消聲彎管的平面邊長大于800mm時，應加設導流吸聲片。導流吸聲片表面應平滑、圓弧均勻、與彎管連接緊密牢固。不得有松動現象。消聲百葉窗，框架應牢固，葉片的片距應均勻，吸聲面方向應符合設計要求。消聲器內外金屬構件表面應涂刷紅丹防銹漆兩道（較好鍍鋅板材可不涂防銹漆）。涂刷前，金屬表面應按需要做好處理，去除鐵銹、油脂等雜物。涂刷時要求無漏涂、起泡、露底等現象。衡量消聲器的好壞主要考慮以下三個方面：消聲器的消聲性能、消聲器的空氣動力性能和消聲器的結構性能。</p><div
