力士樂液壓柱塞泵延長使用壽命和保養(yǎng)方發(fā)

電磁閥是控制元件，主要用來控制氣缸。也有分析儀器或者別的噴槍用來直接控制氣體。電磁閥分為氣動、液壓兩種，工作方式都是一樣的，只是介質不一樣。工作原理就是在一個閥體上開幾個孔，然后用電磁感應控制閥桿的運動來控制堵哪個孔，或者讓哪個孔出氣。以此達到控制的目的長期*: 公司專業(yè)經(jīng)銷德國力士樂Rexroth，在力士樂液壓泵、液壓閥、伺服及比例閥、放大板等產(chǎn)品具有很強的競爭優(yōu)勢，優(yōu)勢產(chǎn)品型號有4WE 、4WM 、DBD 、DR 、ZDB 、Z2FS 系列閥，A4V、A10VS0、A2FO系列柱塞泵，A2FE、A2FM液壓馬達，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，當容積效率下降到72%時，就需要進行常規(guī)維修，更換軸承和老化的密封件，要更換或修復超出配合間隙的磨擦副，使其性能得到恢復。

1、液壓泵：直軸斜盤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油分泵向液壓泵進油口提供壓力油的。自吸油型液壓泵的自吸油能力很強，無需外力供油。氣壓供油的液壓油箱，在每次啟動機器后，必須等液壓漬箱達到使用氣壓后，才能操作機械。如液壓油箱的氣壓不足時就擔任機器，會對液壓泵內的與滑鞭造成拉脫現(xiàn)象，出會造成泵體內回程板與壓板的非正常磨損。采用補油泵供油的柱塞泵，使用3000h后，操作人員每日需對柱塞泵檢查1-2次，檢查液壓泵運轉聲響是否正常。如發(fā)現(xiàn)液壓缸速度下降或悶車時，就應該對補油泵解體檢查，檢查葉輪邊沿是否有刮傷現(xiàn)象，內齒輪泵間隙是否過大。

2、對于自吸油型柱塞泵，液壓油箱內的油液不得低于油標下限，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。

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部三對磨擦副的正常間隙，同時也會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，超過此值就需要更換新口。拆卸下來的軸承，沒有專業(yè)檢測儀器是無法檢測出軸承的游隙的，只能采用目測，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，應注意原軸承的英文字母和型號，柱塞泵軸承大都采用大載荷容量軸承，購買原廠家，原規(guī)格的產(chǎn)品，如果更換另一種品牌，應請教對軸承有經(jīng)驗的人員查表對換，目的是保持軸承的精度等級和載荷容量。

4、三對磨擦副檢查與修復：柱塞桿與缸體孔根據(jù)柱塞泵零件的更換標準，當零件的各種間隙超差時，可按下述方法修復：

（1）缸體鑲裝銅套的，可以采用更換銅套的方法修復。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）缸體加溫熱裝或銅套低溫冷凍擠壓，過盈裝配;（b）采有樂泰膠粘著裝配，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，涂樂泰膠后，旋入裝配。

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

（3）采用“表面工程技術”，方法如下：（a）電鍍技術：在柱塞表面鍍一層硬鉻;（b）電刷鍍技術：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)的維護方法

高溫高塵下工作的液壓系統(tǒng)特點是要采用盡可能大的油箱，靠油箱的自然散熱來滿足液壓系統(tǒng)對溫度的要求，有條件的可以采用冷卻器。要注意防止泄漏，防止煙塵對液壓系統(tǒng)的污染。為防止因液壓油泄漏引發(fā)的火災，應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υ蟊容^高，對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，隨時間的增長液壓油灰逐漸老化變質，定期更換液壓油，對方向泄漏很有必要。

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

　　3）改進絕緣法蘭管接頭。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。原先的設計是用石棉板，石棉板雖然起絕緣的作用，但是強度不夠且不耐油，易爆裂造成泄漏引發(fā)火災。

　　4）短程大缸的液壓缸的密封件盡可能選用比理論設計大一號的密封槽及密封件。

　　5）加強對液壓系統(tǒng)的管理。定制度派專人定期對液壓系統(tǒng)各管接頭巡視，對已經(jīng)發(fā)現(xiàn)有泄漏的兩接合面，應及時更換密封件，防患于未然。
