德國(guó)rexroth力士樂(lè)壓力繼電器是利用液體的壓力來(lái)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(hào)，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(dòng)作，使油路卸壓、換向，執(zhí)行元件實(shí)現(xiàn)順序動(dòng)作，或關(guān)閉電動(dòng)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(duì)柱塞式壓力繼電器(見(jiàn)圖)的工作原理作一介紹:
德國(guó)rexroth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(dòng)柱塞2上移，此位移通過(guò)杠桿放大后推動(dòng)微動(dòng)開(kāi)關(guān)4動(dòng)作。改變彈簧1的壓縮量，可以調(diào)節(jié)繼電器的動(dòng)作壓力。
