力士樂(lè)液壓柱塞泵延長(zhǎng)使用壽命和保養(yǎng)方發(fā)

電磁閥是控制元件，主要用來(lái)控制氣缸。也有分析儀器或者別的噴槍用來(lái)直接控制氣體。電磁閥分為氣動(dòng)、液壓兩種，工作方式都是一樣的，只是介質(zhì)不一樣。工作原理就是在一個(gè)閥體上開(kāi)幾個(gè)孔，然后用電磁感應(yīng)控制閥桿的運(yùn)動(dòng)來(lái)控制堵哪個(gè)孔，或者讓哪個(gè)孔出氣。以此達(dá)到控制的目的長(zhǎng)期*: 公司專(zhuān)業(yè)經(jīng)銷(xiāo)德國(guó)力士樂(lè)Rexroth，在力士樂(lè)液壓泵、液壓閥、伺服及比例閥、放大板等產(chǎn)品具有很強(qiáng)的競(jìng)爭(zhēng)優(yōu)勢(shì)，優(yōu)勢(shì)產(chǎn)品型號(hào)有4WE 、4WM 、DBD 、DR 、ZDB 、Z2FS 系列閥，A4V、A10VS0、A2FO系列柱塞泵，A2FE、A2FM液壓馬達(dá)，HED系列壓力繼電器。

液壓系統(tǒng)的效率主要取決于液壓泵的容積效率，當(dāng)容積效率下降到72%時(shí)，就需要進(jìn)行常規(guī)維修，更換軸承和老化的密封件，要更換或修復(fù)超出配合間隙的磨擦副，使其性能得到恢復(fù)。

1、液壓泵：直軸斜盤(pán)式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補(bǔ)油分泵向液壓泵進(jìn)油口提供壓力油的。自吸油型液壓泵的自吸油能力很強(qiáng)，無(wú)需外力供油。氣壓供油的液壓油箱，在每次啟動(dòng)機(jī)器后，必須等液壓漬箱達(dá)到使用氣壓后，才能操作機(jī)械。如液壓油箱的氣壓不足時(shí)就擔(dān)任機(jī)器，會(huì)對(duì)液壓泵內(nèi)的與滑鞭造成拉脫現(xiàn)象，出會(huì)造成泵體內(nèi)回程板與壓板的非正常磨損。采用補(bǔ)油泵供油的柱塞泵，使用3000h后，操作人員每日需對(duì)柱塞泵檢查1-2次，檢查液壓泵運(yùn)轉(zhuǎn)聲響是否正常。如發(fā)現(xiàn)液壓缸速度下降或悶車(chē)時(shí)，就應(yīng)該對(duì)補(bǔ)油泵解體檢查，檢查葉輪邊沿是否有刮傷現(xiàn)象，內(nèi)齒輪泵間隙是否過(guò)大。

2、對(duì)于自吸油型柱塞泵，液壓油箱內(nèi)的油液不得低于油標(biāo)下限，要保持足夠數(shù)量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長(zhǎng)。

3、液壓泵用軸承柱塞泵zui重要的部件是軸承，如果軸承出現(xiàn)游隙，則不能保證液壓泵內(nèi)部三對(duì)磨擦副的正常間隙，同時(shí)也會(huì)破壞各磨擦副的靜液壓支承油膜厚度，降低柱塞泵軸承的使用壽命。據(jù)液壓泵制造廠提供的資料，軸承的平均使用壽命為10000h，超過(guò)此值就需要更換新口。拆卸下來(lái)的軸承，沒(méi)有專(zhuān)業(yè)檢測(cè)儀器是無(wú)法檢測(cè)出軸承的游隙的，只能采用目測(cè)，如發(fā)現(xiàn)滾柱表面有劃痕或變色，就必須更換。在更換軸承時(shí)，應(yīng)注意原軸承的英文字母和型號(hào)，柱塞泵軸承大都采用大載荷容量軸承，購(gòu)買(mǎi)原廠家，原規(guī)格的產(chǎn)品，如果更換另一種品牌，應(yīng)請(qǐng)教對(duì)軸承有經(jīng)驗(yàn)的人員查表對(duì)換，目的是保持軸承的精度等級(jí)和載荷容量。

4、三對(duì)磨擦副檢查與修復(fù)：柱塞桿與缸體孔根據(jù)柱塞泵零件的更換標(biāo)準(zhǔn)，當(dāng)零件的各種間隙超差時(shí)，可按下述方法修復(fù)：

（1）缸體鑲裝銅套的，可以采用更換銅套的方法修復(fù)。首先把一組柱塞桿處徑修整到統(tǒng)一尺寸，再用1000#以上的砂紙拋光外徑。缸體安裝銅套的三種方法：（a）缸體加溫?zé)嵫b或銅套低溫冷凍擠壓，過(guò)盈裝配;（b）采有樂(lè)泰膠粘著裝配，這咱方法要求銅外套外徑表面有溝槽;（c）缸孔攻絲，銅套外徑加工螺紋，涂樂(lè)泰膠后，旋入裝配。

（2）熔燒結(jié)合方式的缸體與銅套，修復(fù)方法如下：（a）采用研磨棒，手工或機(jī)械方法研磨修復(fù)缸孔;（b）采用座標(biāo)鏜床，重新鏜缸體孔;（c）采用鉸刀修復(fù)缸體孔。

（3）采用“表面工程技術(shù)”，方法如下：（a）電鍍技術(shù)：在柱塞表面鍍一層硬鉻;（b）電刷鍍技術(shù)：在柱塞表面刷鍍耐磨材料;（c）熱噴涂或電弧噴涂或電噴涂：噴涂高碳馬氏體耐磨材料;（d）激光熔敷：在柱塞表面熔敷高硬度耐磨合金粉末。

高溫下液壓系統(tǒng)的維護(hù)方法

高溫高塵下工作的液壓系統(tǒng)特點(diǎn)是要采用盡可能大的油箱，靠油箱的自然散熱來(lái)滿足液壓系統(tǒng)對(duì)溫度的要求，有條件的可以采用冷卻器。要注意防止泄漏，防止煙塵對(duì)液壓系統(tǒng)的污染。為防止因液壓油泄漏引發(fā)的火災(zāi)，應(yīng)選用抗燃或不燃液壓油，如乳化液壓油、水乙二醇液壓油等?？谷蓟虿蝗家簤河蛯?duì)元件要求比較高，對(duì)于不能采用抗燃或不燃液壓油的液壓系統(tǒng)，防止泄漏就尤為重要，主要措施如下：

　　1）定期更換液壓油。液壓系統(tǒng)在高溫高塵下使用，隨時(shí)間的增長(zhǎng)液壓油灰逐漸老化變質(zhì)，定期更換液壓油，對(duì)方向泄漏很有必要。

　　2）定期更換密封件。油液系統(tǒng)長(zhǎng)期處在高溫的環(huán)境下工作，密封件容易老化，要及時(shí)更新老化的密封件。

　　3）改進(jìn)絕緣法蘭管接頭。由于該系統(tǒng)的所有執(zhí)行缸都帶電，它們同泵站的絕緣靠絕緣法蘭管接頭。原先的設(shè)計(jì)是用石棉板，石棉板雖然起絕緣的作用，但是強(qiáng)度不夠且不耐油，易爆裂造成泄漏引發(fā)火災(zāi)。

　　4）短程大缸的液壓缸的密封件盡可能選用比理論設(shè)計(jì)大一號(hào)的密封槽及密封件。

　　5）加強(qiáng)對(duì)液壓系統(tǒng)的管理。定制度派專(zhuān)人定期對(duì)液壓系統(tǒng)各管接頭巡視，對(duì)已經(jīng)發(fā)現(xiàn)有泄漏的兩接合面，應(yīng)及時(shí)更換密封件，防患于未然。
