A4VSO250DR/30R-PPB13N00力士樂液壓油泵

進油過程

當凸輪的凸起部分轉(zhuǎn)過去后，在彈簧力的作用下，柱塞向下運動，柱塞上部空間（稱為泵油室）產(chǎn)生真空度，當柱塞上端面把柱塞套上的進油孔打開后，充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進入泵油室，柱塞運動到下止點，進油結(jié)束

回油過程

柱塞向上供油，當上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，出油閥在彈簧力的作用下迅速關閉，停止供油。此后柱塞還要上行，當凸輪的凸起部分轉(zhuǎn)過去后，在彈簧的作用下，柱塞又下行。此時便開始了下一個循環(huán)。

柱塞泵以一個柱塞為原理介紹，一個柱塞泵上有兩個單向閥，并且方向相反，柱塞向一個方向運動時缸內(nèi)出現(xiàn)負壓，這時一個單向閥打開液體被吸入缸內(nèi)，柱塞向另一個方向運動時，將液體壓縮后另一個單向閥被打開，被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運動后就形成了連續(xù)供油。

 

液壓泵為液壓傳動提供加壓液體的一種液壓元件，是泵的一種。它的功能是把動力機（如電動機和內(nèi)燃機等）的機械能轉(zhuǎn)換成液體的壓力能。影響液壓泵的使用壽命因素很多，除了泵自身設計、制造因素外和一些與泵使用相關元件（如聯(lián)軸器、濾油器等）的選用、試車運行過程中的操作等也有關系。

液壓泵的工作原理是運動帶來泵腔容積的變化，從而壓縮流體使流體具有壓力能。

必須具備的條件就是泵腔有密封容積變化。 

液壓泵的種類：

1、按流量是否可調(diào)節(jié)可分為：變量泵和定量泵。輸出流量可以根據(jù)需要來調(diào)節(jié)的稱為變量泵，流量不能調(diào)節(jié)的稱為定量泵。

2、按液壓系統(tǒng)中常用的泵結(jié)構(gòu)分為：齒輪泵、葉片泵和柱塞泵3種。

齒輪泵：體積較小，結(jié)構(gòu)較簡單，對油的清潔度要求不嚴，價格較便宜；但泵軸受不平衡力，磨損嚴重，泄漏較大。

葉片泵：分為雙作用葉片泵和單作用葉片泵。這種泵流量均勻、運轉(zhuǎn)平穩(wěn)、噪音小、作壓力和容積效率比齒輪泵高、結(jié)構(gòu)比齒輪泵復雜。

柱塞泵：容積效率高、泄漏小、可在高壓下工作、大多用於大功率液壓系統(tǒng)；但結(jié)構(gòu)復雜，材料和加工精度要求高、價格貴、對油的清潔度要求高。

1．進口液壓柱塞泵（簡稱泵）磨損的三個階段

進口的液壓泵的磨損分為初期磨損，正常磨損，異常磨損三個階段。

1.1初期磨損階段：泵在零件制造過程中，零件金屬表面有一定的微觀不平度（表面粗糙度）軸或孔存在的橢圓度與不直度，在金屬表面發(fā)生初期相對運動時，泵零件間相對高速運動，此時摩擦副間會產(chǎn)生輕微的摩擦磨損，零件處于初期磨損階段。

1.2正常磨損階段：經(jīng)過一段時間的磨合，摩擦副間生成新的，精度等級更高的粗糙度，磨損速度減慢。進入一段相對比較長的穩(wěn)定使用階段。

1.3異常磨損階段：在此階段中，金屬材料達到疲勞周期的額定壽命，金屬表面將產(chǎn)生疲勞層，疲勞層在泵高溫高壓的特殊使用狀態(tài)下，金屬表層易發(fā)生顆粒狀脫落，因此，磨損急劇增長，較后導致零件失效。

1.4泵在運行中的相對運動的三對摩擦副（靜份量大承關系）零件之間的磨損，使零件間的縫隙加大，泵內(nèi)泄漏量隨之增多，油溫也相應升高。泵軟壽命是從初期磨合期到穩(wěn)定使用階段進而到疲勞剝落期階段（劇烈磨損階段）。這三個階段時間的長短主要取決于所使用的液壓介質(zhì)的清潔度。

1.5影響泵的軟壽命還有另外一個決定性因素，就是泵的軸承的使用壽命。因為軸承在泵殼內(nèi)軸向載荷轉(zhuǎn)動，泵殼內(nèi)的三大摩擦副（1缸體配流面與配流盤；2柱塞桿與缸孔；3滑靴與斜盤）零件高速摩擦轉(zhuǎn)動，金屬表面相對運動時，金屬與金屬產(chǎn)生接觸摩擦，發(fā)生粘結(jié)和切削，而且由于局部高溫，造成大尺寸金屬氧化物顆粒疲勞剝落，剝落的金屬顆粒因無法排出泵殼外而積存在液壓泵殼內(nèi)。因泵殼體充滿液壓油，沉積的金屬顆粒與液壓油混雜在一起隨泵主軸及缸體的轉(zhuǎn)動又在殼體內(nèi)旋流漂移，造成泵內(nèi)軸承的加劇磨損。軸承磨損到一定程度后游隙加大，軸承游隙加大后軸承的回轉(zhuǎn)精度降低后，無法保證缸體與配流盤的相對運動精度，因此又破壞了泵三對摩擦副之間的靜液壓的平衡，被破壞的靜液壓支承（三對摩擦副）又會加速磨損。

油泵可以分為容積式和非容積室（蝸輪式）兩種。非容積式有離心泵、軸流泵等，利用高速旋轉(zhuǎn)的葉輪使進口產(chǎn)生真空吸入液體，并在出口連續(xù)輸出壓力液體。這種泵進口與出口相通，效率隨液體粘度增加而降低，并且輸出液體量隨出口壓力升高而顯著減少。

容積式泵是通過一個封閉的空間容積的變化來實現(xiàn)吸油和壓油的。當這個封閉容積由小變大時進行吸油，由大變小時進行壓油。典型的為力士樂柱塞泵，柱塞從缸孔中拉出時吸油，壓進時壓油。這種泵進口與出口是被隔開的，效率取決于隔開吸壓油腔的各對運動零件間的結(jié)構(gòu)工藝間隙及油液的粘度等。粘度越率越高，輸油量幾乎保持不變（因效率略有影響，另外壓力升高至18MPa，油液會被壓縮1%）。

（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。[1] 

熔燒結(jié)合方式的缸體與銅套，安裝方法如下：

（a）采用研磨棒，手工或機械方法研磨修復缸孔；

（b）采用坐標鏜床，重新鏜缸體孔；

（c）采用鉸刀修復缸體孔。[1] 

采用“表面工程技術(shù)”，安裝方法如下：

（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。

泵工作前，先將泵內(nèi)充滿液體，然后啟動離心泵，葉輪快速轉(zhuǎn)動，葉輪的葉片驅(qū)使液體轉(zhuǎn)動，液體轉(zhuǎn)動時依靠慣性向葉輪外緣流去，同時葉輪從吸入室吸進液體，在這一過程中，葉輪中的液體繞流葉片，在繞流運動中液體作用一升力于葉片，反過來葉片以一個與此升力大小相等、方向相反的力作用于液體，這個力對液體做功，使液體得到能量而流出葉輪，這時液體的動能與壓能均加大
