style="text-indent:25px">電磁換向閥的主要故障及損排除：換向頻率過(guò)高，線圈過(guò)熱。干式型電磁閥換向閥推桿處外滲漏油：1．一般電磁閥兩端的油腔是泄油腔或回油腔，應(yīng)檢查該腔壓力是否過(guò)高。如果在系統(tǒng)中多個(gè)電磁閥的泄油或回油管道串接在一起造成背壓過(guò)高，則應(yīng)將它們分別單獨(dú)接回油箱。2．推桿處的動(dòng)密封“O”形密封圈磨損過(guò)大，應(yīng)更換。板式連接電磁換向閥與底板的接合面處滲油：1．安裝底板應(yīng)磨削加工，光潔度達(dá)0.8，同時(shí)應(yīng)有不平度誤差要求100：0.01，并不得凸起。 2．安裝螺釘擰得太松。3．螺釘材料不符合要求，強(qiáng)度不夠。目前，許多板式連接電磁換向閥的安裝螺釘均采用合金鋼螺釘。如果原螺釘斷裂或丟失，隨意更換一般碳鋼螺釘，會(huì)因受油壓作用引起拉伸變形，造成接合面的滲漏。4．電磁換向閥底面“O”形密封圈老化變質(zhì)，不起密封作用，應(yīng)更換。質(zhì)量原因?qū)е碌墓收希ǔＴ陔姶艙Q向閥通電工作數(shù)小時(shí)內(nèi)即可明顯察覺(jué)。</p><div

style="text-indent:25px">電磁換向閥是利用電磁鐵推動(dòng)閥芯來(lái)控制液流方向的。采用電磁換向閥可以使操作輕便，容易實(shí)現(xiàn)自動(dòng)化操作，因此應(yīng)用極廣。電磁換向閥只是采用電磁鐵來(lái)操縱滑閥閥芯運(yùn)動(dòng)，而閥芯的結(jié)構(gòu)及型式可以是各種各樣的，所以電磁滑閥可以是二位二通、二位三通、二位四通、三位四通和三位五通等多種型式。一般二位閥用一個(gè)電磁鐵，三位閥需用兩個(gè)電磁鐵。操縱電磁閥用的電磁鐵分為交、直流兩種，交流電磁鐵的電壓一般為 220伏。其特點(diǎn)是啟動(dòng)力較大，換向時(shí)間短，價(jià)廉。但當(dāng)閥芯卡住或吸力不夠而使鐵芯吸不上時(shí)，電磁鐵容易因電流過(guò)大而燒壞，故工作可靠性較差，動(dòng)作時(shí)有沖擊，壽命較低。直流電磁鐵電壓一般為 24伏。其優(yōu)點(diǎn)是工作可靠，不會(huì)因閥芯卡住而燒壞，壽命長(zhǎng)，體積小，但啟動(dòng)力較交流電磁鐵小，而且在無(wú)直流電源時(shí)，需整流設(shè)備。為了提高電磁換向閥的工作可靠性和壽命，近年來(lái)，國(guó)內(nèi)外正日益普遍地采用濕電磁鐵，這種電磁鐵與滑閥推桿間無(wú)須密封，消除了 O形密封圈處的摩擦力，它的電磁線圈外面直接用工程塑料封固，不另作金屬外殼，這樣既保證了絕緣，又利于散熱，所以工作可靠，沖擊小，壽命長(zhǎng)。磁換向閥主要是利用電磁鐵通電吸合時(shí)產(chǎn)生的力來(lái)操縱滑閥閥芯移動(dòng)的。氣動(dòng)電磁調(diào)節(jié)閥廠家</p><p
