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(zhǎng)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(zhǎng)度來校驗(yàn)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(zhǎng)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(zhǎng)度增長(zhǎng)，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(zhǔn)。用調(diào)反饋杠桿法來校準(zhǔn)定位器的步驟如下：a.輸入4mA.DC信號(hào)，按常用的調(diào)零法調(diào)零點(diǎn);b.輸入20mA.DC信號(hào)，按常用調(diào)量程法調(diào)節(jié)量程;c.反復(fù)進(jìn)行a，b步;d.若零點(diǎn)、量程無法校準(zhǔn)，調(diào)整閥桿上的銷釘以改變反饋杠桿的有效長(zhǎng)度，使行程增大或減小，杠桿有效長(zhǎng)度縮短，行程增大;反之，行程減小。e.反復(fù)進(jìn)行以上步驟，直到零點(diǎn)、量程均達(dá)到要求即可。江蘇一體式閥門定位器公司閘閥是發(fā)電廠開/關(guān)應(yīng)用的第—選擇。</p><div
