style="text-indent:25px">電磁換向閥的安全性要注意這些：1、腐蝕性介質(zhì)：宜選用塑料王電磁閥和全不銹鋼；對(duì)于強(qiáng)腐蝕的介質(zhì)必須選用隔離膜片式。中性介質(zhì)，也宜選用銅合金為閥殼材料的電磁閥，否則，閥殼中常有銹屑脫落，尤其是動(dòng)作不頻繁的場(chǎng)合。氨用閥則不能采用銅材。2、危險(xiǎn)性環(huán)境：必須選用相應(yīng)防爆等級(jí)產(chǎn)品，露天安裝或粉塵多場(chǎng)合應(yīng)選用防水，防塵品種。3、電磁閥公稱壓力應(yīng)超過(guò)管內(nèi)較高工作壓力。適用性介質(zhì)特性：1）質(zhì)氣，液態(tài)或混合狀態(tài)分別選用不同品種的電磁閥；2）介質(zhì)溫度不同規(guī)格產(chǎn)品，否則線圈會(huì)燒掉，密封件老化，嚴(yán)重影響壽命命；3）介質(zhì)粘度，通常在50cSt以下。若超過(guò)此值，通徑大于15mm時(shí)，用多功能電磁閥；通徑小于15mm時(shí)，用高粘度電磁閥。4）介質(zhì)清潔度不高時(shí)都應(yīng)在電磁閥前配裝反沖過(guò)濾閥，壓力低時(shí)，可選用直動(dòng)膜片式電磁閥；5）介質(zhì)若是定向流通，且不允許倒流，需用雙向流通；6）介質(zhì)溫度應(yīng)選在電磁閥允許范圍之內(nèi)。山東三位電磁換向閥根據(jù)電磁換向閥的工作性質(zhì)，對(duì)電磁換向閥閥體內(nèi)孔的磨損仍不可完全避免。</p><div

2、C3 H型機(jī)能：該機(jī)能特點(diǎn)是中位時(shí)各油口全部通油，系統(tǒng)將卸荷。使用該機(jī)能的電磁換向閥，液壓系統(tǒng)在中位時(shí)因PT口相通而卸荷，并且AB口也相通，執(zhí)行元件可以自由移動(dòng)。換向沖擊相比C2較大。</p><p style="text-indent:25px">電磁換向閥如何安裝要注意什么？1)電磁換向閥的軸線必須按水平方向安裝，如垂直方向安裝，受閥芯、銜鐵等零件重量影響，將造成換向或復(fù)位不正常。2)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中接在一起造成背壓過(guò)高，則應(yīng)將它們單獨(dú)接回油箱。3)安裝底板表面應(yīng)磨削加工，同時(shí)應(yīng)有平面度要求，不得凸起。4)安裝螺釘不能擰得太松，否則板式連接電磁換向閥與底板的接合處滲油。5)電磁換向閥應(yīng)注意控制電源參數(shù)應(yīng)與電磁閥一致。電磁換向閥是依靠電磁鐵的推力達(dá)到換向目的，電磁鐵分直流或交流，電磁鐵應(yīng)與控制電源參數(shù)相一致，否則有可能造成換向閥不能正常工作或燒毀電磁鐵。電磁換向閥注意事項(xiàng)：使用電壓應(yīng)與線圈電壓一致。</p><div
