我們常見(jiàn)的電接點(diǎn)壓力表的應(yīng)用有很多，比如增壓水罐的水壓控制；真空泵的工作壓力控制；變壓器的溫度保護(hù)控制（其用的是電接點(diǎn)壓力式溫度計(jì)）等等。既然電接點(diǎn)壓力表的應(yīng)用如此***，那么我們有必要來(lái)熟練掌握。下面我們就從以下幾個(gè)方面來(lái)詳細(xì)地介紹：1、工作原理（1）電接點(diǎn)壓力表有三個(gè)指針，一個(gè)是實(shí)際壓力讀數(shù)指針（黑色），另一個(gè)是壓力設(shè)定下限指針（綠色），***一個(gè)是壓力設(shè)定上限指（紅色）。（2）具體工作原理，我們以增壓水罐的水壓控制來(lái)講述：比如，要求水罐內(nèi)壓力（指表壓）低于，供水電機(jī)啟動(dòng)抽水；壓力高于，供水電機(jī)停止抽水。水泵電機(jī)的主回路和控制回路如下圖示:主回路大家都非常熟悉，就不多講了，這里主要講控制回路。旋轉(zhuǎn)轉(zhuǎn)換開(kāi)關(guān)，1和2接通時(shí)，為手動(dòng)控制，這里也不多講述。1和3接通時(shí)，為壓力表全自動(dòng)控制。壓力表全自動(dòng)控制的情況下，實(shí)際壓力指針接的是公共線，即3號(hào)線，也是電源線。下限指針接的是4號(hào)線。上限指針接的是5號(hào)線。剛開(kāi)始表壓為零時(shí)，實(shí)際壓力指針與下限指針接通，即3和4接通，中繼KA1吸合，接觸器KM吸合并自鎖，抽水電機(jī)運(yùn)行。隨著抽水電機(jī)的運(yùn)行，表壓逐漸上升，實(shí)際壓力指針與下限指針脫離，逐漸往大壓力值方向擺動(dòng)。江西漢木不銹鋼壓力表的原理漢木（上海）儀表科技有限公司的主要產(chǎn)品。</p><div
