style="text-indent:25px">提高不銹鋼氣動執(zhí)行器效率的方法：在閥門選配氣動執(zhí)行器的時候就應該考慮閥門的開關時間要求，在考慮安全的前提下，如果考慮氣動執(zhí)行器的進氣和排氣的速度，可以在排管的選擇上可以選擇較大的管徑?？梢栽跉鈩訄?zhí)行器增加一個存儲罐,氣源的氣體要先進入存儲罐,然后才能進入執(zhí)行器,對于型號比較大的的閥門或者需求氣體較多的用這個方法較好。一般用這種方式方法可以讓重要閥門有應急氣源儲備。要求開關比較快，可以采取將氣體通過的管道換成更粗的，這樣以來氣體的進氣量就會增多，開關自然就會也就快了。氣動執(zhí)行器可根據(jù)閥門需要選擇方向，順時針或逆時針旋轉。</p><div

style="text-indent:25px">在把氣動/電動執(zhí)行機構安裝到閥門之前，必須考慮以下因素。閥門的運行力矩加上生產(chǎn)廠家的推薦的安全系數(shù)/根據(jù)操作狀況。執(zhí)行機構的氣源壓力或電源電壓。執(zhí)行機構的類型雙作用或者單作用(彈簧復位)以及一定氣源下的輸出力矩或額定電壓下的輸出力矩。執(zhí)行機構的轉向以及故障模式(故障開或故障關)正確選擇一個執(zhí)行機構是非常重要的，如執(zhí)行機構過大，閥桿可能受力過大。相反如執(zhí)行機構過小，側不能產(chǎn)生足夠的力矩來充分操作閥門。一般地說，我們認為操作閥門所需的力矩來自閥門的金屬部件(如球芯，閥瓣)和密封件(閥座)之間的磨擦。根據(jù)閥門使用場合，使用溫度，操作頻率，管道和壓差，流動介質(zhì)(潤滑、干燥、泥漿)，許多因素均影響操作力。閥門定位器的作用是利用反饋原理來改善執(zhí)行器的性能,使執(zhí)行器能按控制器的控制信號,實現(xiàn)準確的定位。龍巖不銹鋼氣動執(zhí)行器制造廠家</p><p

如果是帶電磁閥,也是一樣, 氣缸內(nèi)的氣體是從電磁閥上的消音器排出,氣動執(zhí)行器雙作用和單作用都行，雙作用執(zhí)行器用二位五通電磁閥，單作用執(zhí)行器用二位三通電磁閥，執(zhí)行器內(nèi)部的氣體可以通過電磁閥消音器排出。龍巖不銹鋼氣動執(zhí)行器制造廠家</p></p><br /><p>文章來源地址:
