3 存在問(wèn)題原因
原F40型定位器性能差，壽命短，內(nèi)部橡膠密封圈老化，控制輸出線性較差，氣室內(nèi)部普遍存在漏氣、串氣現(xiàn)象，且控制輸出氣孔較小，極易堵塞，造成控制輸出氣源不穩(wěn)定，執(zhí)行機(jī)構(gòu)動(dòng)作不靈活，經(jīng)常造成風(fēng)門擋板失控，使被調(diào)工況超出允許范圍，影響機(jī)組的安全運(yùn)行。
4 定位器更換技術(shù)
拆除原來(lái)的F40定位器，加工ABB定位器與現(xiàn)氣缸連接轉(zhuǎn)換接頭，ABB定位器與轉(zhuǎn)換接頭裝配，ABB定位器安裝到氣缸上，重新進(jìn)行管路配接、接線，ABB定位器送電，機(jī)務(wù)定位風(fēng)門擋板開(kāi)度位置，單體調(diào)試，系統(tǒng)聯(lián)調(diào)，終調(diào)試達(dá)到工作要求。
1）定位器配件齊全，安裝固定牢固，無(wú)松動(dòng)現(xiàn)象，定位器和氣缸連接無(wú)空行程。2）定位器接線要準(zhǔn)確，氣源管路連接正確，定位器控制氣源管路各接口要纏繞生料帶。3）擋板或閥門的全開(kāi)和全關(guān)定位要和機(jī)務(wù)、運(yùn)行人員一塊進(jìn)行，確保定位準(zhǔn)確。4）檢查電氣轉(zhuǎn)換器各功能菜單顯示正常。檢查電氣轉(zhuǎn)換器各參數(shù)設(shè)置準(zhǔn)確。切換至組態(tài)模式，修改組態(tài)參數(shù)。5）儀用氣源閥門打開(kāi)，調(diào)整減壓閥壓力，使氣源壓力符合要求，對(duì)失氣后保位手柄進(jìn)行復(fù)位。6）ABB定位器進(jìn)行自動(dòng)整定。滿足擋板全開(kāi)全關(guān)旋轉(zhuǎn)角度的條件。滿足4～20MA輸入信號(hào)和擋板開(kāi)關(guān)方向的對(duì)應(yīng)關(guān)系在定位器更換前后一致，零點(diǎn)、量程和閥門實(shí)際開(kāi)度一致。7）通過(guò)就地操作面板或手掄操作執(zhí)行機(jī)構(gòu)，檢查執(zhí)行機(jī)構(gòu)和擋板或閥門動(dòng)作情況，執(zhí)行器動(dòng)作靈活無(wú)卡澀。8）通過(guò)CRT遠(yuǎn)方操作執(zhí)行機(jī)構(gòu)，核實(shí)開(kāi)關(guān)方向、閥位反饋和擋板或閥門動(dòng)作情況應(yīng)一致。9）系統(tǒng)靜態(tài)閉環(huán)試驗(yàn)，保證控制軟件的正確性。

5 TZID-C型I/P電氣轉(zhuǎn)換器
TZID-C型定位器核心是微控制處理器CPU，所有程序的處理運(yùn)算皆在此。輸入信號(hào)及位置反饋經(jīng)過(guò)4000步12位，20ms采樣的A／D轉(zhuǎn)換器進(jìn)行處理，從而保證了信號(hào)處理的精度及快速性，CPU的供電直接取自輸入信號(hào)，操作程序包括用于自動(dòng)調(diào)整參數(shù)的自整定過(guò)程，及自適應(yīng)控制程序，用于精確定位的優(yōu)化控制操作，通過(guò)帶三位三通放大器的電氣轉(zhuǎn)換器驅(qū)動(dòng)氣動(dòng)執(zhí)行機(jī)構(gòu)，從CPU發(fā)出的定位電信號(hào)比例地轉(zhuǎn)換成氣信號(hào)，成比例地調(diào)節(jié)3／3氣動(dòng)開(kāi)關(guān)，氣體從定位器輸出至氣動(dòng)執(zhí)行器及氣體的排放均成比例地調(diào)節(jié)，當(dāng)?shù)竭_(dá)設(shè)定定位值時(shí)，3／3氣動(dòng)開(kāi)關(guān)鎖定在中間狀態(tài)；TZID-C定位器配有的操作面板，包括兩排LCD顯示器和4個(gè)按鍵，如圖5。

操作鍵盤的優(yōu)化設(shè)計(jì)適用于就地組態(tài)，調(diào)校及監(jiān)測(cè)。同時(shí)．組態(tài)、操作及監(jiān)測(cè)功能可以通過(guò)HART通訊協(xié)議與PC機(jī)連接，并由TZID-C內(nèi)置通訊端口來(lái)完成：還可以通過(guò)FSK-Modem在4～20mA信號(hào)線的任意點(diǎn)接入進(jìn)行通訊。采用模塊化的設(shè)計(jì)，任何附加功能
可以在基本模件的基礎(chǔ)上隨意擴(kuò)展。只要插入相應(yīng)的模件，既可實(shí)現(xiàn)模擬及數(shù)字反饋功能。也可以選裝限位開(kāi)關(guān)(微動(dòng)開(kāi)關(guān))及機(jī)械指示。
