R480073352力士樂,REXROTH電磁閥特點(diǎn):體積小,功率低,但介質(zhì)壓差范圍受限,必須滿足壓差條件。 兩位三通電磁閥通常與單作用氣動(dòng)執(zhí)行機(jī)構(gòu)配套使用,兩位是兩個(gè)位置可控:開-關(guān),三通是有三個(gè)通道通氣,一般情況下1個(gè)通道與氣源連接,另外兩個(gè)通道1個(gè)與執(zhí)行機(jī)構(gòu)的進(jìn)氣口連接0820024054?R480059375 0821305215?R480073342

德國博士REXROTH力士樂電磁閥原理及維修 縱觀國內(nèi)外電磁閥,到目前為止,從動(dòng)作方式上可分為三大類即:直動(dòng)式、反沖式、先導(dǎo)式,而從閥瓣結(jié)構(gòu)和材料上的不同以及原理上的區(qū)別反沖式又可分為:膜片式反沖電磁閥、活塞式反沖電磁閥;先導(dǎo)式又可分為:先導(dǎo)式膜片電磁閥、先導(dǎo)式活塞電磁閥;從閥座及密封材料上分又可分為:軟密封電磁閥、鋼性密封電磁閥、半鋼性密封電磁 一、直動(dòng)式電磁閥 原理:常閉型直動(dòng)式電磁閥通電時(shí),電磁線圈產(chǎn)生電磁吸力把閥芯提起,使關(guān)閉件離遠(yuǎn)開閥座密封副打開;斷電時(shí),電磁力消失,靠彈簧力把關(guān)閉元件壓在閥座上閥門關(guān)閉。(常開型與此相反) 特點(diǎn):在真空、負(fù)壓、零壓差時(shí)能正常工作,DN50以下可任意安裝,但電磁頭體積較大。如我公司引進(jìn)HERION公司技術(shù)生產(chǎn)的直動(dòng)電磁閥可用于1.33×10-4 Mpa真空。
