電液換向閥的技術(shù)規(guī)格

電液換向閥是由電磁換向閥作先導(dǎo)閥與液動換向閥組合而成，由電磁閥引過油液，推動主
滑閥運動，使主油路換向，適合于大流量液壓系統(tǒng)中，其中使用過程中應(yīng)該注意事項：電
液的猾閥的安裝應(yīng)該保持軸線呈水平方向，不允許傾斜或垂直方向安裝，應(yīng)該保證兩端有
足夠的拆卸空間，以便折卸端或更換電磁鐵。管接處連接處，禁止使用油漆，麻絲等堵塞
螺紋連接口，對于機能M\K型的閥，如采用內(nèi)供形式的應(yīng)在說主閥回油客路上加大于等于
的壓力。
電磁換向閥是連接電氣控制系統(tǒng)和液壓系統(tǒng)的元件。由電氣系統(tǒng)的按鈕開關(guān)、限位開關(guān)、
行程開關(guān)、壓力繼電器等其他電氣元件發(fā)出的電訊器，通過電磁鐵動作，使電磁滑閥移
動，來實現(xiàn)油路的換向，順序動作及卸荷等。按使用電源電壓的不同，電磁換向閥分為
交流AC220V,直流24V二種。D2\E2型溫式閥乃干式閥的改進型 ，系將濕式電磁銜鐵和推
桿連成一體。在磁軛和銜鐵之間通入壓力油，取消了中間動密封，得以徹底解決了漏油
問題，同時也避免了因密封損壞、油溫升過高所引起的線圈過熱以及沖擊震動和噪音等
缺點，且因電磁鐵吸力增加，匹配的復(fù)位彈簧剛性增磊，可較大地提高可靠性和使用壽
命。

• 在液壓系統(tǒng)中管路管徑該如何選擇呢？

  在液壓系統(tǒng)中管路管徑該如何選擇呢？在液壓系統(tǒng)中管路管徑該如何選擇呢？具體情況還需要具體分析，因為這需要看泵站和執(zhí)行機構(gòu)之間遠不遠？對執(zhí)行機構(gòu)的速度是否要求嚴格，還有的液壓系統(tǒng)是連續(xù)工作，還是工作一會休息很長時間。我們可以通過液壓系統(tǒng)高工作壓力及大通過流量來選擇管路大小和壁厚，并考慮是什么材質(zhì)的管道。這些在液壓系統(tǒng)手冊上都會有相關(guān)資料。 1、液壓系統(tǒng)中管路管徑如何選擇——管道怎么選型？ 首先看材質(zhì)，

• 如何保證液壓系統(tǒng)的油液清潔度？

  油液清潔度對于控制要求嚴格，配合精度精密的電液伺服閥是引起失效的主要原因，會引起堵塞、卡死、沖蝕等多種失效形式。作為伺服閥生產(chǎn)廠家，我們也常常會收到用戶反饋伺服閥工作異常的情況，伺服閥返廠分解后發(fā)現(xiàn)，導(dǎo)致伺服閥故障的原因大多是油液清潔度不達標(biāo)導(dǎo)致的。如何保證液壓系統(tǒng)的油液清潔度？如何保證液壓系統(tǒng)的油液清潔度？我們有以下建議：1、在條件許可的情況下，應(yīng)定期檢查工作液的污染度。2、應(yīng)建立新油是臟油的概

• 液控單向閥

  液控單向閥是依靠控制流體壓力，可以使單向閥反向流通的閥。這種閥在煤礦機械的液壓支護設(shè)備中占有較重要的地位。液控單向閥與普通單向閥不同之處是多了一個控制油路，當(dāng)控制油路未接通壓力油液時，液控單向閥就象普通單向閥一樣工作，壓力油只從進油口流向出油口，不能反向流動。當(dāng)控制油路有控制壓力輸入時，活塞**桿在壓力油作用下向右移動，用**桿**開單向閥，使進出油口接通。若出油口大于進油口就能使油液反向流動。分類液控

• 電液換向閥的工作方式

  電液換向閥是與電磁操縱的先導(dǎo)閥組合成一體的液動換向閥。用控制油路中的壓力油推動閥芯。電液換向閥和液控換向閥主要用在流量**過電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對執(zhí)行元件的動作進行控制，或?qū)τ鸵旱牧鲃臃较蜻M行控制。 電液換向閥和液控換向閥主要用在流量**過電磁換向閥正常工作允許范圍的液壓系統(tǒng)中，對執(zhí)行元件的動作進行控制，或?qū)τ鸵旱牧鲃臃较蜻M行控制。當(dāng)兩個電磁閥線圈通電時，平衡孔回路關(guān)閉，泄流孔回路
