力士樂(lè)分步直動(dòng)式電磁閥:
原理:REXROTH電磁閥是一種直動(dòng)和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒(méi)有壓差時(shí),通電后,電磁力直接把先導(dǎo)小閥和主閥關(guān)閉件依次向上提起,閥門(mén)打開(kāi)。當(dāng)入口與出口達(dá)到啟動(dòng)壓差時(shí),通電后,力士樂(lè)電磁閥電磁力先導(dǎo)小閥,主閥下腔壓力上升,上腔壓力下降,從而利用壓差把主閥向上推開(kāi);斷電時(shí),先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動(dòng)關(guān)閉件,向下移動(dòng),使閥門(mén)關(guān)閉。
特點(diǎn):REXROTH力士樂(lè)電磁閥在零壓差或真空、高壓時(shí)亦能可*動(dòng)作,但功率較大,要求必須水平安裝。
REXROTH電磁閥液壓裝置中容易產(chǎn)生噪聲的元件一般認(rèn)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(lè)REXROTH電磁閥的噪聲有流速聲和機(jī)械聲二種。流速聲中主要由油液振動(dòng)、空穴以及液壓沖擊等原因產(chǎn)生的噪聲。機(jī)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。
上海維特銳在德國(guó)與REXROTH合作,可長(zhǎng)期穩(wěn)定供應(yīng)力士樂(lè)電磁閥,REXROTH導(dǎo)軌,力士樂(lè)柱塞泵等產(chǎn)品
