style="text-indent:25px">定位器就是有一個作用，就是給閥門的開度定位的。給閥門的開度信號是多少，閥門就開在那個位置。裝有定位器的閥門都叫調(diào)節(jié)閥，就是閥門的開度可以受到控制的閥門。對于調(diào)節(jié)閥有兩種，一種是氣動調(diào)節(jié)閥，另一種是電動調(diào)節(jié)閥。由于氣動調(diào)節(jié)閥的響應速度遠大于電動調(diào)節(jié)閥，因此氣動調(diào)節(jié)閥用的比較多，連云港雙作用閥門定位器公司。氣動調(diào)節(jié)閥的定位器是根據(jù)控制閥門開度大小的電流信號，產(chǎn)生一個磁力驅(qū)動擋板，連云港雙作用閥門定位器公司，使其輸出到閥門執(zhí)行機構(gòu)的氣源壓力發(fā)生變化，使閥門朝開或關(guān)的方向動作，連云港雙作用閥門定位器公司。將連接在閥桿上的銷釘靠近定位器，這樣就將反饋杠桿的有效長度縮短。連云港雙作用閥門定位器公司</p><div

style="text-indent:25px">定位器可以調(diào)節(jié)的參數(shù)還有零位彈簧的彈性系數(shù)和反饋杠桿的有效長度，由于調(diào)零彈簧常在線性區(qū)域內(nèi)工作，所以只討論通過改變反饋杠桿的有效長度來校驗定位器。我們可以將連接在閥桿上的銷釘靠近定位器，這樣就將反饋杠桿的有效長度縮短，即減小增大，行程也增大，反之，可將反饋杠桿的有效長度增長，則其行程減小。因此，將此方法配合常用的調(diào)校法可增大行程變化范圍，易于定位器的校準。用調(diào)反饋杠桿法來校準定位器的步驟如下：a.輸入4mA.DC信號，按常用的調(diào)零法調(diào)零點;b.輸入20mA.DC信號，按常用調(diào)量程法調(diào)節(jié)量程;c.反復進行a，b步;d.若零點、量程無法校準，調(diào)整閥桿上的銷釘以改變反饋杠桿的有效長度，使行程增大或減小，杠桿有效長度縮短，行程增大;反之，行程減小。e.反復進行以上步驟，直到零點、量程均達到要求即可。連云港雙作用閥門定位器公司定位器安裝時需要專業(yè)人員進出操作。</p><div

style="text-indent:25px">一般定位器所配用閥門的流量特性是由閥芯的加工特性決定的。閥芯有直線、等百分比、快開等流量特性，如果工藝要求與此相符，則智能定位器的輸出特性應選擇為線性輸出，這樣就能保證整體閥門流量特性與原設(shè)計要求相符。當實際使用中，閥芯如有流量特性不能適合工藝要求時，則可以通過定位器輸出特性的改變來改變閥門的整體流量特性。如:可以修改智能定位器為等百分比輸出，將具有線性閥芯的閥門變?yōu)榈劝俜直攘髁刻匦缘拈y門來使用;或修改智能定位器為反向等百分比輸出，可將等百分比閥芯的閥門調(diào)整為線性流量特性的閥門來使用。</p><p style="text-indent:25px">定位器在工作的時候有一些常見的問題，整理了一些問題幫助在使用中理解體會。1.定位器無法自整定：自整定時在屏幕上顯示這表示電角度不在規(guī)定范圍內(nèi)，這要求安裝時需注意，如下圖畫圈處所示，不要超出指示范圍。2.液晶無顯示：用萬用表帶載測量11、12端子直流電壓，觀察電壓正負極是否接線正確，沒問題需要確定11、12端子電壓是否在8.2-8.7V之間，電壓在這個范圍內(nèi)，一般為主板問題；電壓不在這個范圍內(nèi)，故障出在DCS接口或傳輸導線上。定位器遇到問題時要及時的進行解決。定位器建立了閥桿位移量與控制器輸出信號之間的一一對應關(guān)系。</p><div

style="text-indent:25px">定位器根據(jù)閥門動作方式可分為直行程和角行程；根據(jù)信號形式分為氣動和電氣；根據(jù)閥門執(zhí)行機構(gòu)原理分為單作用和雙作用；另外根據(jù)定位器自身工作原理還可以分出多種形式、規(guī)格、型號等。定位器的電纜入口采用M20x1.5電纜接頭，6至12mm夾緊范圍。有一個第二個M20x1.5螺紋孔可以用于額外的外殼連接，如果需要。螺絲端子設(shè)計用于電線橫截面為0.2至2.5mm2。擰緊螺釘0.5至0.6Nm。必須連接設(shè)定點的電線到位于的終端11和12住房。只使用電流源。在連接電纜入口的時候要格外的注意，不正確的電信號會損壞電源定位。定位器要保證表面光潔度，減少填料摩擦。連云港雙作用閥門定位器公司</p><p style="text-indent:25px">定位器具有智能通訊和現(xiàn)場顯示功能。連云港雙作用閥門定位器公司</p><p style="text-indent:25px">定位器的輸入信號是標準電流或電壓信號，例如，4~20mA電流信號或1~5V電壓信號等，在定位器內(nèi)部將電信號轉(zhuǎn)換為電磁力，然后輸出氣信號到撥動控制閥。智能定位器它將控制室輸出的電流信號轉(zhuǎn)換成驅(qū)動調(diào)節(jié)閥的氣信號，根據(jù)調(diào)節(jié)閥工作時閥桿摩擦力，抵消介質(zhì)壓力波動而產(chǎn)生的不平衡力，使閥門開度對應于控制室輸出的電流信號。并且可以進行智能組態(tài)設(shè)置相應的參數(shù)，達到改善控制閥性能的目的。定位器是調(diào)節(jié)閥的主要附件，它接受調(diào)節(jié)器的輸出信號，然后以它的輸出信號去控制氣動調(diào)節(jié)閥，當調(diào)節(jié)閥動作后，閥桿的位移又通過機械裝置反饋到定位器，閥位狀況可以通過電信號傳給上位系統(tǒng)。連云港雙作用閥門定位器公司</p><p
