美國PARKER電子壓力繼電器#派克沈陽現(xiàn)貨
工作原理壓力繼電器是利用液體的壓力來啟閉電氣觸點(diǎn)的液壓電氣轉(zhuǎn)換元件。當(dāng)系統(tǒng)壓力達(dá)到壓力繼電器的調(diào)定值時(shí)，發(fā)出電信號，使電氣元件（如電磁鐵、電機(jī)、時(shí)間繼電器、電磁離合器等）動作，使油路卸壓、換向，執(zhí)行元件實(shí)現(xiàn)順序動作，或關(guān)閉電動機(jī)使系統(tǒng)停止工作，起安全保護(hù)作用等。壓力繼電器有柱塞式、膜片式、彈簧管式和波紋管式四種結(jié)構(gòu)形式。下面對柱塞式壓力繼電的工作原理作一介紹：當(dāng)從繼電器下端進(jìn)油口3進(jìn)入的液體壓力達(dá)到調(diào)定壓力值時(shí)，推動柱塞2上移，此位移通過杠桿放大后推動微動開關(guān)4動作。改變彈簧1的壓縮量，可以調(diào)節(jié)繼電器的動作壓力。
