真空閥門的零位和行程。翻開定位器蓋子，對(duì)應(yīng)里面零位和行程旋鈕從頭調(diào)整即可，首要調(diào)整零位旋鈕，使行程歸零。然后在調(diào)理行程旋鈕，對(duì)準(zhǔn)行程。假如經(jīng)過定位器調(diào)整還無法對(duì)準(zhǔn)零位，就要經(jīng)過從頭拆裝閥桿和薄膜執(zhí)行器推桿銜接部位，合作定位器調(diào)整即可處理。2. 真空閥門內(nèi)漏大，已經(jīng)超越正常值?；蛟S零位漂移，從頭對(duì)準(zhǔn)零位。查看閥芯和閥座磨損情況，磨損嚴(yán)重就要維修或替換。閥內(nèi)有異物卡住，關(guān)不到位。介質(zhì)壓差大，薄膜執(zhí)行器驅(qū)動(dòng)力小形成封閉不嚴(yán)，要替換大標(biāo)準(zhǔn)執(zhí)行器。3. 真空閥門不動(dòng)作。查看氣源是不是正常。再查看空氣過濾減壓閥，電氣閥門定位器節(jié)流孔是不是堵塞，控制系統(tǒng)傳送信號(hào)是不是正常。膜片是不是破損。4. 真空閥門震顫或不穩(wěn)定。查看控制信號(hào)是不是正常，再查看空氣過濾減壓閥減壓是不是正常，電氣閥門定位器內(nèi)放大器部件問題或磁鋼有問題。壓差大，執(zhí)行組織剛度小也會(huì)形成震顫。填料過緊，對(duì)閥桿的上下動(dòng)作阻力過大。</p><p
