REXROTH電磁閥液壓裝置中容易產(chǎn)生噪聲的元件一般認為是泵和閥,閥中又以溢流閥和電磁換向閥等為主。產(chǎn)生噪聲的因素很多。
力士樂電磁閥的噪聲有流速聲和機械聲二種。流速聲中主要由油液振動、空穴以及液壓沖擊等原因產(chǎn)生的噪聲。機械聲中主要由閥中零件的撞擊和磨擦等原因產(chǎn)生的噪聲。
REXROTH電磁閥由閥體、閥罩、電磁組件、彈簧及密封結(jié)構(gòu)等部件組成,動鐵芯底部的密封塊借助彈簧的壓力將閥體進氣口關(guān)閉。通電后,電磁鐵吸合,動鐵芯上部帶彈簧的密封塊把排氣口關(guān)閉,氣流從進氣口進入膜頭,起到控制作用。
當(dāng)力士樂電磁閥失電時,電磁力消失,動鐵芯在彈簧力作用下離開固定鐵芯,向下移動,將排氣口打開,堵住進氣口,膜頭氣流經(jīng)排氣口排出,膜片恢復(fù)原來位置。在我們的制氧設(shè)備中,在透平膨脹機進口薄膜調(diào)節(jié)閥的緊急切斷等處有應(yīng)用。
力士樂電磁閥爆炸性環(huán)境:必須選用相應(yīng)防爆等級產(chǎn)品,露天安裝或粉塵多場合應(yīng)選用防水,防塵品種。
REXROTH電磁閥公稱壓力應(yīng)超過管內(nèi)zui高工作壓力。
上海維特銳在德國與REXROTH合作,可長期穩(wěn)定供應(yīng)REXROTH電磁閥,REXROTH換向閥,REXROTH油泵,REXROTH導(dǎo)軌,力士樂柱塞泵等產(chǎn)品
