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REXROTH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。 力士樂分步直動式電磁閥: 原理:REXROTH電磁閥是一種直動和先導(dǎo)式相結(jié)合的原理,當(dāng)入口與出口沒有壓差時,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,閥門打開。當(dāng)入口與出口達到啟動壓差時,通電后,力士樂電磁閥電磁力先導(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;斷電時,先導(dǎo)閥利用彈簧力或介質(zhì)壓力推動關(guān)閉件,向下移動,使閥門關(guān)閉。 特點:REXROTH力士樂電磁閥在零壓差或真空、高壓時亦能可*動作,但功率較大,要求必須水平安裝。 上海維特銳在德國與REXROTH合作,可長期穩(wěn)定供應(yīng)力士樂電磁閥,REXROTH導(dǎo)軌,力士樂柱塞泵等產(chǎn)品 4WE 10 C3X/OCG24N9K4/V 4WE 10 U10-3X/CG24N9K4/T06 4WE 10 E4X/CG110N9DKL 4WE 10 JB3X/OFCG24N9K4 4WE 10 J3X/CW110N9K4/B08V 4WE 10 D28-3X/CG24K4 4WE 10 Y3X/CG24K4 4WE 10 J4X/CG48NDK6L 4WE 10 E4X/CW110N9DK25L 4WE 10 D3X/OCG125N9K4 4WE 10 U10B3X/CG24K4 4WE 10 D3X/CG24N9K4QMAG24/A06 4WE 10 R4X/CG24N9DKL 4WE 10 Y4X/CG24N9DL 4WE 10 E4X/CW230N9DAL/V 4WE 10 E67-3X/CG24N9K4/A08T06 4WE 10 G4X/CW110N9DKL 4WE 10 D4X/CG48N9DKL/B15 4WE 10 J4X/CW230N9DAL/V 4WE 10 D4X/CG24N9DKLQMAG24 4WE 10 EB3X/CW230N9K4/V 4WE 10 HA3X/CW230N9K4/V 4WE 10 D3X/CG110N9K4/B08 4WE 10 J4X/CG24N9DL1 4WE 10 E4X/CG24NDL 4WE 10 EA3X/CG24N9K4QM0G24 4WE 10 D4X/OCW230N9DL 4WE 10 J47-3X/CG24N9K4 4WE 10 EB4X/CG24DAL 4WE 10 J3X/CG205N9K4/A06 4WE 10 D3X/CG96N9K4QMAG24/A06 4WE 10 D3X/CG205N9K4QMAG24/A06 4WE 10 E3X/CG24K4QR0G24S 4WE 10 D4X/CW110N9DL/V 4WE 10 D3X/CG220N9K4QMAG24/V 4WE 10 HB3X/CG12N9K4 4WE 10 X7-3X/CW127NK4 4WE 10 U3X/CG205N9K4 4WE 10 J4X/CW110N9DKL 4WE 10 E73-3X/CG96N9K4/A12V 4WE 10 E3X/CW100N9K4 4WE 10 H4X/CW230N9DL 4WE 10 D4X/CG24N9DK25L 4WE 10 J4X/CW200N9DL 4WE 10 EA4X/CG24N9DL 4WE 10 E4X/CG24N9DKL/V 4WE 10 EB4X/CW110N9DL 4WE 10 D4X/CG24DKL
