流量?jī)x表也有“不聽(tīng)話”時(shí)

  流量?jī)x表在使的過(guò)程當(dāng)中也會(huì)遇到不可避免的一些故障,來(lái)簡(jiǎn)單說(shuō)說(shuō)這些故障吧:

(1)在使用過(guò)程當(dāng)中流量指示值?。阂话闱闆r下是這幾種因素造成的:先是檢測(cè)元元器件是否損壞(零點(diǎn)太低應(yīng)該是顯示有問(wèn)題;正壓室堵或漏;系統(tǒng)的壓力過(guò)低;參與調(diào)節(jié)的參數(shù)還要檢查調(diào)節(jié)器、調(diào)節(jié)閥及電磁閥;線路是不是短路或著斷路;)

 ?。?)在使用過(guò)程當(dāng)中流量指示大:主要原因是負(fù)壓室引壓系統(tǒng)堵或漏。變送器需要調(diào)校的可能不大。

  (3)在使用過(guò)程當(dāng)中流量波動(dòng)大:流量參數(shù)不參與調(diào)節(jié)的,一般為工藝原因;參與調(diào)節(jié)的,可檢查調(diào)節(jié)器的PID參數(shù);帶隔離罐的參數(shù),檢查引壓管內(nèi)是否有氣泡,正負(fù)壓引壓管內(nèi)液體是否一樣高。
