style="text-indent:25px">有些氣動通風(fēng)閥門組件結(jié)構(gòu)在一個(gè)行程動作方向比在另一個(gè)有3至5倍長的時(shí)滯時(shí)間。這種特性典型地是由定位器設(shè)計(jì)的不對稱特性引起的。它會嚴(yán)重地限制把回路整定到總體性能的能力。一旦時(shí)滯時(shí)間已經(jīng)過去，且閥門開始響應(yīng)，閥門響應(yīng)時(shí)間的剩余部分來自閥門組件的動態(tài)時(shí)間。這個(gè)動態(tài)時(shí)間主要是由定位器和執(zhí)行器組合的動態(tài)特性決定的。這兩個(gè)部件必須很好地匹配以減少閥門的總的響應(yīng)時(shí)間。例如，在一個(gè)氣動通風(fēng)閥門組件里，定位器必須有一個(gè)高動態(tài)增益以減小閥門組件的動態(tài)時(shí)間。這個(gè)動態(tài)增益主要由定位器里的動力放大器提供。換言之，定位器放大器或滑閥能夠越快地提供大量的壓縮空氣給執(zhí)行器，閥門的響應(yīng)時(shí)間也將越快。</p><p style="text-indent:25px">儀表供氣壓力也可能對通風(fēng)閥門組件的動態(tài)性能產(chǎn)生很大的影響。例如，它能明顯地影響定位器的增益和總耗氣量。固定增益定位器通常已經(jīng)在某一特殊供氣壓力下進(jìn)行了優(yōu)化。然而，這個(gè)增益可能會在供氣壓力的很小變化范圍內(nèi)成兩倍或更多倍地變化。例如，一個(gè)在20Psig的供氣壓力下進(jìn)行優(yōu)化的定位器可能會被發(fā)現(xiàn)當(dāng)供氣壓力增加到35Psig時(shí)，它的增益減少了一半。供氣壓力也會影響供應(yīng)給執(zhí)行器的空氣量?？諝饬縿t決定動作速度。它也與耗氣量直接相關(guān)。高增益滑閥定位器需要消耗5倍于在動力放大階段使用放大器的更加高效的高性能二級定位器所需的氣量。通風(fēng)閥門組件的時(shí)滯時(shí)間需要較小化閥門組件的死區(qū)，不管這個(gè)死區(qū)是由于閥門密封結(jié)構(gòu)的摩擦力引起的，還是由于填料的摩擦力、閥軸的扭轉(zhuǎn)、執(zhí)行器或者定位器的結(jié)構(gòu)引起的。通風(fēng)閥門輸送的介質(zhì)，包括原料、反應(yīng)中間體，通常是腐蝕性介質(zhì)。</p><div
