style="font-size:16px;">工作原理</span> </h1> <p> <span style="font-size:16px;">能通過把制冷系統(tǒng)的壓力變換為電信號控制電氣系統(tǒng)的工作。壓力控制器由高、低壓控制兩部分組成的，它們分別與壓縮機(jī)高、低壓管相連。當(dāng)制冷劑進(jìn)入壓力控制器后，氣壓會使波紋管產(chǎn)生變形，變形的波紋管迫使傳動桿移動，使微動開關(guān)接通或斷開。當(dāng)制冷系統(tǒng)高壓壓力過高時，高壓控制部分的微動開關(guān)斷開，切斷壓縮機(jī)的供電回路，使壓縮機(jī)停機(jī)，以避免壓縮機(jī)被高壓損壞。當(dāng)壓縮機(jī)吸氣壓力過低時，低壓控制部分的微動開關(guān)斷開，切斷壓縮機(jī)的供電回路，使壓縮機(jī)停機(jī)。</span> </p> <p> <span style="font-size:16px;">當(dāng)系統(tǒng)內(nèi)壓力高于某一個設(shè)定壓力計時，不同的壓感元件（彈簧管、膜片、膜盒、波紋管、活塞等）的自由端產(chǎn)生位移，通過鏈接導(dǎo)桿推動開關(guān)內(nèi)碟片瞬時發(fā)生移動；當(dāng)壓力降至額定的恢復(fù)值時，碟片瞬時反向移動，開關(guān)自動復(fù)位，**終輸出一個開關(guān)量的電信號。</span> </p> <p> <span style="font-size:16px;">可用于對感壓元件無腐蝕作用的氣體、液體或蒸汽等介質(zhì)IIA、IIB、IIC類CT1~ CT6組性氣體混合物場所實現(xiàn)壓力自動控制。可用于中性或腐蝕性氣體和液體介質(zhì)。設(shè)定值范圍可調(diào)，調(diào)節(jié)范圍為0.02～42Mpa．切換差不可調(diào)．壓力控制器包括范圍比較廣品種比較多，有差壓控制器，防爆壓力開關(guān)，防爆差壓開關(guān)，壓力變送器，差壓變送器，風(fēng)壓開關(guān)，風(fēng)壓變送器。</span>
