HYDAC賀德克EDS1700系列壓力繼電器,壓力開(kāi)關(guān),4位繼電器開(kāi)關(guān)觸點(diǎn),1模擬量輸出及4位數(shù)字顯示。開(kāi)關(guān)點(diǎn),回程開(kāi)關(guān)滯后及輔助功能可通過(guò)觸摸按鍵調(diào)整。壓力繼電器是液壓系統(tǒng)中當(dāng)流體壓力達(dá)到預(yù)定值時(shí),使電接點(diǎn)動(dòng)作的元件。壓力繼電器也可定義為將壓力轉(zhuǎn)換成電信號(hào)的液壓元器件,客戶根據(jù)自身的壓力設(shè)計(jì)需要,通過(guò)調(diào)節(jié)壓力繼電器,實(shí)現(xiàn)在某一設(shè)定的壓力時(shí),輸出一個(gè)電信號(hào)的功能。

德國(guó)HYDAC賀德克壓力繼電器EDS1791-P-250-000工作原理:

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(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。

應(yīng)用場(chǎng)合:用于安全保護(hù)、控制執(zhí)行元件的順序動(dòng)作、用于泵的啟閉、用于泵的卸荷。

注意: 壓力繼電器必須放在壓力有明顯變化的地方才能輸出電信號(hào)。若將壓力繼電器放在回油路上,由于回油路直接接回油箱,壓力也沒(méi)有變化,所以壓力繼電器也不會(huì)工作。
