天康電接點壓力表廣泛應用于石油、化工、冶金、電力、機械等工業部門或機電設備配套中測量無爆炸危險的各種流體介質壓力儀表經與相應的電氣器件(如繼電器及變頻器等)配套使用,即可對被測(控)壓力系統 實現自動控制和發信(報警)的目的。

天康電接點壓力表結構原理：

電接點壓(ya)力(li)表由測(ce)(ce)量(liang)系(xi)統、指(zhi)示系(xi)統、磁助電接點裝置(zhi)、外殼(ke)、調整裝置(zhi)和(he)接線盒(插頭座)等組成(cheng)。一般電接點壓(ya)力(li)表是(shi)用(yong)于測(ce)(ce)量(liang)對銅和(he)銅合金不起腐蝕作用(yong)的(de)氣(qi)體(ti)、液體(ti)介質(zhi)的(de)正負壓(ya)力(li)，不銹鋼電接點壓(ya)力(li)表用(yong)于測(ce)(ce)量(liang)對不銹鋼不起腐蝕作用(yong)的(de)氣(qi)體(ti)、液體(ti)介質(zhi)的(de)正負壓(ya)力(li)并(bing)在壓(ya)力(li)達(da)到預定(ding)值時發出信號(hao)，接通(tong)控制電路，達(da)到自(zi)動(dong)控制的(de)報警的(de)目的(de)。

電(dian)接點壓力(li)表(biao)基于(yu)測(ce)(ce)量(liang)系(xi)統(tong)(tong)中的(de)(de)(de)彈(dan)簧(huang)管在(zai)被測(ce)(ce)介質的(de)(de)(de)壓力(li)作用下，迫使彈(dan)簧(huang)管之末端產(chan)生相(xiang)應的(de)(de)(de)彈(dan)性變(bian)形一位移，借助拉桿經齒(chi)輪傳(chuan)動(dong)機構的(de)(de)(de)傳(chuan)動(dong)并(bing)予放(fang)大，由固(gu)定(ding)齒(chi)輪上的(de)(de)(de)指示(連同觸頭)逐將(jiang)被測(ce)(ce)值在(zai)度盤(pan)上指示出來(lai)。與此同時(shi)，當(dang)其(qi)與設定(ding)指針上的(de)(de)(de)觸頭(上限(xian)或(huo)下限(xian))相(xiang)接觸(動(dong)斷或(huo)動(dong)合)的(de)(de)(de)瞬(shun)時(shi)，致使控(kong)制(zhi)系(xi)統(tong)(tong)中的(de)(de)(de)電(dian)路得以斷開或(huo)接通，以達到自動(dong)控(kong)制(zhi)和發信報警的(de)(de)(de)目的(de)(de)(de)。

電(dian)器(qi)原理：

以控制壓(ya)(ya)縮機電(dian)機為(wei)例：儲氣(qi)灌(guan)壓(ya)(ya)力到(dao)達(da)下限自(zi)動開啟，到(dao)達(da)上限自(zi)動停機。

控制過(guo)程如下：在壓力(li)(li)到(dao)達(或開(kai)機時低與)下*，電(dian)(dian)接(jie)(jie)點(dian)壓力(li)(li)表的(de)(de)(de)活動(dong)觸(chu)點(dian)(電(dian)(dian)源共(gong)公端)與下限觸(chu)頭(tou)(tou)接(jie)(jie)通，繼電(dian)(dian)器J1動(dong)作并自鎖， 其(qi)常開(kai)觸(chu)頭(tou)(tou)閉合驅動(dong)J3，電(dian)(dian)動(dong)機得電(dian)(dian)運轉。 當(dang)壓力(li)(li)到(dao)達上(shang)*，活動(dong)觸(chu)點(dian)與上(shang)限觸(chu)頭(tou)(tou)接(jie)(jie)通，繼電(dian)(dian)器J2動(dong)作，其(qi)常閉觸(chu)頭(tou)(tou)斷開(kai)，切斷J1供(gong)電(dian)(dian)，其(qi)常開(kai)點(dian)斷開(kai)，J3釋放，電(dian)(dian)機停轉。 如此往復，達到(dao)自動(dong)控制的(de)(de)(de)目的(de)(de)(de)。

檢定

防(fang)爆(bao)電(dian)接點壓力(li)表

1.電(dian)(dian)接點(dian)(dian)壓力(li)表(biao) 實際上是(shi)壓力(li)表(biao)操縱的電(dian)(dian)路開關，僅(jin)是(shi)普通壓力(li)表(biao)上多了一個電(dian)(dian)接點(dian)(dian)信號(hao)裝置(zhi)，因此，對(dui)壓力(li)部分的檢定(ding)與檢定(ding)普通壓力(li)表(biao)相同，只(zhi)是(shi)壓力(li)部分檢定(ding)合格后，尚需增加對(dui)電(dian)(dian)接點(dian)(dian)信號(hao)裝置(zhi)的檢定(ding)而已(yi)。

2.電接點(dian)壓力表檢定的步驟(zou):

將(jiang)壓力表裝在(zai)校(xiao)驗器上(shang)，用撥針器分(fen)別(bie)將(jiang)兩信號接觸(chu)指針撥到上(shang)限(xian)及下限(xian)以外，然(ran)后進行(xing)示值檢定。示值檢定合格后，將(jiang)上(shang)限(xian)和(he)下限(xian)的(de)(de)信號接觸(chu)指針分(fen)別(bie)定于三個以上(shang)不同的(de)(de)檢定點上(shang)，緩慢地增加或降低壓力，一直到發出(chu)信號的(de)(de)瞬時(shi)為止，這時(shi)標準壓力表的(de)(de)讀數與信號指針示值間的(de)(de)偏差，不得超過(guo)允許基本誤(wu)差的(de)(de)絕對值。

產品應(ying)用(yong):

在電接(jie)點(dian)(dian)(dian)壓力表裝置(zhi)的(de)電接(jie)觸(chu)信號針上，裝有(you)(you)可調節的(de)磁鋼，可以(yi)增(zeng)加(jia)接(jie)點(dian)(dian)(dian)吸(xi)力，加(jia)快接(jie)觸(chu)動(dong)(dong)作(zuo)，從(cong)而使觸(chu)點(dian)(dian)(dian)接(jie)觸(chu)可靠(kao)，消除電弧(hu)，能有(you)(you)效的(de)避(bi)免儀表由于工作(zuo)環境振動(dong)(dong)或(huo)介(jie)質壓力脈動(dong)(dong)造(zao)成(cheng)觸(chu)點(dian)(dian)(dian)的(de)頻繁(fan)關(guan)(guan)斷。所以(yi)電接(jie)點(dian)(dian)(dian)壓力表具有(you)(you)動(dong)(dong)作(zuo)可靠(kao)、使用壽命長、觸(chu)點(dian)(dian)(dian)開關(guan)(guan)功率較大等優點(dian)(dian)(dian)。

常見問題處理:

電接點壓力表過早(zao)或過晚發生信(xin)號：

是觸(chu)(chu)點(dian)(dian)位置不正或觸(chu)(chu)點(dian)(dian)金屬桿松(song)動。觸(chu)(chu)點(dian)(dian)位置不正，將觸(chu)(chu)點(dian)(dian)校正垂(chui)直到恰當發(fa)生信號(hao)為止(zhi)。觸(chu)(chu)點(dian)(dian)金屬桿松(song)動，應(ying)設法(fa)固牢，較(jiao)輕(qing)微者，采用適當放大游(you)絲，增加游(you)絲的反力矩，也有效果。

電(dian)接點(dian)(dian)裝(zhuang)置不(bu)(bu)發(fa)生信(xin)號：觸(chu)點(dian)(dian)太臟(zang)接觸(chu)不(bu)(bu)良;信(xin)號裝(zhuang)置絕緣(yuan)層(ceng)(ceng)受潮;電(dian)路不(bu)(bu)通(tong)等;觸(chu)點(dian)(dian)太臟(zang)，用砂紙打(da)磨除去(qu)污物;絕緣(yuan)層(ceng)(ceng)受潮，用熱風吹干。
