style="font-size:16px;">首先你應(yīng)該斷開(kāi)電源，打開(kāi)壓力罐底部的排污閥，放水至不流水，擰下壓力控制器，繼續(xù)放水，直到水全部放完，然后關(guān)閉排污閥，裝上壓力控制器，一定要密封好，不能漏氣，接上電源，就OK了。</span> </p> <p> <span style="font-size:16px;">水泵壓力控制器的工作原理：工作介質(zhì)（油、氣體、水）直接作用在金屬膜片上，通過(guò)金屬膜片的變形量來(lái)反映工作介質(zhì)的壓力大小，同時(shí)輸出檢測(cè)信號(hào)或控制信號(hào)。</span> </p> <p> <span style="font-size:16px;">水泵壓力控制器一般是采用金屬316L膜片式的傳感器，可用于中性油、氣體介質(zhì)和水。控制器的設(shè)定值可調(diào)，調(diào)節(jié)范圍-0.1 ~ 40MPa量程段任意可選。</span> 壓力控制器的分類(lèi)有哪幾種？哈爾濱兩路報(bào)警壓力控制器</p><p
