調(diào)節(jié)閥使用過久會(huì)導(dǎo)致行程不準(zhǔn)，通俗的說在想開到某個(gè)位置總是有較大的誤差。

行程為0-100%，選取最大點(diǎn)進(jìn)行調(diào)校，分別是0、25、50、75、100，都是百分?jǐn)?shù)表示。尤其是機(jī)械式閥門定位器，調(diào)校時(shí)需要把定位器內(nèi)部的調(diào)節(jié)零位和調(diào)節(jié)跨度的兩個(gè)手動(dòng)的部件位置清楚在哪里。

假如以氣開調(diào)節(jié)閥為例，進(jìn)行調(diào)校。

調(diào)零點(diǎn)，控制室或信號(hào)發(fā)生器給予4mA，調(diào)節(jié)閥應(yīng)該全關(guān)，達(dá)不到全關(guān)進(jìn)行調(diào)零。調(diào)零完成直接調(diào)50%這個(gè)點(diǎn)，與之相差進(jìn)行跨度調(diào)整，同時(shí)注意反饋桿與閥桿應(yīng)該是處于垂直狀態(tài)。調(diào)好后再進(jìn)行100%這個(gè)點(diǎn)調(diào)整，調(diào)節(jié)好后再?gòu)?-100%之間的五個(gè)點(diǎn)反復(fù)調(diào)整，直到開度精確為止。

從機(jī)械式定位器到智能式定位器。站在科技方面看，科技發(fā)展的神速，給予一線維護(hù)人降低了勞動(dòng)強(qiáng)度。個(gè)人認(rèn)為，想鍛煉動(dòng)手能力和學(xué)到技術(shù)，機(jī)械式定位器是的，尤其對(duì)于新入門的儀表人員。智能式定位器說白了，會(huì)看懂說明書上幾個(gè)字，手指動(dòng)動(dòng)就行了，什么調(diào)零點(diǎn)調(diào)量程，調(diào)行程一切自動(dòng)調(diào)整，只要在哪里傻傻的等著它自己玩完了就整理了現(xiàn)場(chǎng)走人就是。對(duì)機(jī)械式的，很多部件要自己動(dòng)手拆動(dòng)手修理再安裝，對(duì)于動(dòng)手能力肯有有提升，而且對(duì)其內(nèi)部結(jié)構(gòu)更有印象。

不管是是非智能的，其對(duì)于整個(gè)自動(dòng)化生產(chǎn)過程是處于主導(dǎo)地位的，一旦“罷工”，調(diào)節(jié)無從說起，自動(dòng)化控制失去意義。
