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(yùn)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(xiàng)：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(jī)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(shí)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(jìn)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(diǎn)，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。

• 柱塞泵

  柱塞泵是液壓系統(tǒng)的一個重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動，使密封工作容腔的容積發(fā)生變化來實(shí)現(xiàn)吸油、壓油。柱塞泵具有額定壓力高、結(jié)構(gòu)緊湊、效率高和流量調(diào)節(jié)方便等優(yōu)點(diǎn)。柱塞泵被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場合，諸如液壓機(jī)、工程機(jī)械和船舶中。柱塞泵一般分為單柱塞泵、臥式柱塞泵、軸向柱塞泵和徑向柱塞泵。單柱塞泵結(jié)構(gòu)組成主要有偏心輪、柱塞、彈簧、缸體、兩個單向閥。柱塞與缸體孔之間形成密閉容積。偏

• 齒輪泵的工作原理簡介

  齒輪泵的工作原理簡介齒輪泵的概念是很簡單的，即它的較基本形式就是兩個尺寸相同的齒輪在一個緊密配合的殼體內(nèi)相互嚙合旋轉(zhuǎn)，這個殼體的內(nèi)部類似“8”字形，兩個齒輪裝在里面，齒輪的外徑及兩側(cè)與殼體緊密配合。來自于擠出機(jī)的物料在吸入口進(jìn)入兩個齒輪中間，并充滿這一空間，隨著齒的旋轉(zhuǎn)沿殼體運(yùn)動，最后在兩齒嚙合時排出。CBQL-E550/532,CBQL-E550/540,CBQL-E550/550,齒輪泵幫浦C

• 引導(dǎo)式溢流閥的使用說明

  推薦粘度 正常工作時所推薦粘度：15--400cSt。如閥帶回油阻尼器，粘度范圍必須是15-200cSt。推薦油液 可使用以下任何一種液壓油液石油基油：石油相當(dāng)于ISO VG32或VG46的油液。合成液：使用磷酸酯液或多元醇酯液。當(dāng)用磷酸酯液時，請用特殊的氟橡膠密封。含水液：使用水——乙二醇液。工作油溫 連續(xù)工作的油溫為-17—+17℃。污染控制 應(yīng)當(dāng)控制液壓油液的污染，否則會導(dǎo)致閥的損壞或縮短使

• 疊加式電控減壓閥的工作原理

  ?閥不工作時，閥芯在彈簧作用下處于較下端位置，閥(單向減壓閥PRCV)的進(jìn)、出油口是相通的，亦即閥是常開. 將先導(dǎo)式減壓閥(疊加式減壓閥MSPR)和先導(dǎo)式溢流閥(疊加式減壓閥SPR)進(jìn)行比較，它們之間有如下幾點(diǎn)不同之處： (1)減壓閥(疊加式減壓閥MPR)保持出口壓力基本不變，而溢流閥(疊加式減壓閥(引導(dǎo)型)MPRP/A/B)保持進(jìn)口處壓力基本不變。 (2)在不工作時，減壓閥進(jìn)、出油口互
