液壓系統(tǒng)組成

一個(gè)完整的液壓系統(tǒng)由五個(gè)部分組成，即動(dòng)力元件、執(zhí)行元件、控制元件、輔助元件和工作介質(zhì)。

動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。動(dòng)力元件指液壓系統(tǒng)中的液壓泵，它向整個(gè)液壓系統(tǒng)提供動(dòng)力。液壓泵的結(jié)構(gòu)形式一般有齒輪泵、葉片泵、柱塞泵、螺桿泵。

執(zhí)行元件的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動(dòng)負(fù)載作直線往復(fù)運(yùn)動(dòng)或回轉(zhuǎn)運(yùn)動(dòng)。執(zhí)行元件有液壓缸和液壓馬達(dá)。

挖制元件(即各種液壓閥)在液壓系統(tǒng)中控制和調(diào)節(jié)液體的壓力、流量和方向。

類型 PV7...A 液壓泵是直動(dòng)式葉片泵，其排量體積可調(diào)。

基本上由殼體，蓋板，轉(zhuǎn)子，葉片，定子環(huán)，壓縮彈簧，調(diào)整螺釘和控制板組成。為限制大流量，該泵配有調(diào)節(jié)螺釘。驅(qū)動(dòng)轉(zhuǎn)子在定子環(huán)中旋轉(zhuǎn)。轉(zhuǎn)子中導(dǎo)入的葉片在離心力的作用下貼緊定子環(huán)的內(nèi)跑合面。

吸油和排油過程

運(yùn)輸流體所需的腔室由葉片，轉(zhuǎn)子，定子環(huán)，控制板和蓋板組成。

轉(zhuǎn)子旋轉(zhuǎn)時(shí)室體積增加，腔室通過吸油通道填充流體。達(dá)到大室體積后，腔室從吸油側(cè)分離。

隨著轉(zhuǎn)子繼續(xù)旋轉(zhuǎn)，高壓流體側(cè)的連接打開，腔室縮小并迫使流體通過壓力油口進(jìn)入系統(tǒng)。

壓力控制

定子環(huán)由彈簧固定在其初始的偏心位置。系統(tǒng)中所需的大工作壓力是在調(diào)節(jié)螺釘處通過彈簧設(shè)定。的壓力是由于對(duì)抗彈簧力的工作阻力作用于定子

環(huán)內(nèi)跑合面的壓力側(cè)而產(chǎn)生的。

達(dá)到相關(guān)壓力（由設(shè)定的彈簧力決定）后，定子環(huán)朝零位置的方向移出其偏心位置。流量自我調(diào)節(jié)至當(dāng)時(shí)所需的值。當(dāng)達(dá)到

彈簧處設(shè)置的大設(shè)定壓力時(shí)，泵會(huì)將流量調(diào)回至幾乎為零。工作壓力得到保持，且僅更換泄露流體。流體的損失和加熱從而降至低水平。

液壓泵提供壓力油以驅(qū)動(dòng)如馬達(dá)或油缸等這樣的液壓部件，主泵由泵和泵組成，輸出軸通過液壓泵柱塞與各泵的缸體連接，當(dāng)輸出軸與缸體一起轉(zhuǎn)動(dòng)時(shí)，柱塞在缸體中移動(dòng)，吸入并排出液壓油。為了控制主泵流量，改變缸體的傾斜角，使柱塞行程根據(jù)傾斜角度增加或減小，通過伺服活塞的上下移動(dòng)改變了缸體的傾斜角，從而使主泵流量增加或者減小。

泵由轉(zhuǎn)子2、定子3、葉片4、配油盤和端蓋等部件所組成。定子的內(nèi)表面是圓柱形孔。轉(zhuǎn)子和定子之間存在著偏心。葉片在轉(zhuǎn)子的槽內(nèi)可靈活滑動(dòng)，在轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)的離心力以及通入葉片根部壓力油的作用下，葉片頂部貼緊在定子內(nèi)表面上，于是兩相鄰葉片、配油盤、定子和轉(zhuǎn)子間便形成了一個(gè)個(gè)密封的工作腔。當(dāng)轉(zhuǎn)子按逆時(shí)針方向旋轉(zhuǎn)時(shí)，圖右側(cè)的葉片向外伸出，密封工作腔容積逐漸加大，產(chǎn)生真空，于是通過吸油口6和配油盤5上窗口將油吸入

使用要點(diǎn)

1.為了使葉片泵可靠地吸油，其轉(zhuǎn)速必須在500～1500r/min的范圍，轉(zhuǎn)速太低時(shí)，葉片不能緊壓定子的內(nèi)表面和吸油；轉(zhuǎn)速太高則造成泵的“吸空”現(xiàn)象，泵的工作不正常。油的粘度要選用適當(dāng)，粘度太大，吸油阻力加大；油液過稀，間隙影響，真空度不夠，會(huì)對(duì)吸油造成不良影響。

2.葉片泵對(duì)油中的污物很敏感，工作可靠性較差，油液不清會(huì)使葉片卡死，因此必須注意油液良好過濾和環(huán)境清潔。

3.因泵的葉片有安裝傾角，故轉(zhuǎn)子只允許單向旋轉(zhuǎn)，不應(yīng)反向使用，否則會(huì)使葉片折斷。

葉片泵的安裝位置葉片泵應(yīng)安裝在油面以下，并應(yīng)靠近油箱，在吸油側(cè)安裝一個(gè)

過濾精度為50~80μm迅的線隙式濾油器。由于條件所限，葉片泵必須安裝在油面以上時(shí)，其吸油高度應(yīng)距較低油位，不大于500mm。這種安裝方法，對(duì)吸油連接管路接頭，必須注意密封良好，若密封不良時(shí)，極易造成葉片泵吸人少許空氣，而摻雜有氣泡的破裂聲，嚴(yán)重時(shí)油箱內(nèi)有氣泡。

變量泵與定量泵的區(qū)別

1.在變量葉片泵中,當(dāng)葉片處于壓油區(qū)時(shí),葉片底部通壓力油,當(dāng)葉片處于吸油區(qū)時(shí),葉片底部通吸油腔,這樣,葉片的頂部和底部的液壓力基本平衡,這就避免了定量葉片泵在吸油區(qū)定子內(nèi)表面嚴(yán)重磨損的問題.如果在吸油腔葉片底部仍通壓力油,葉片頂部就會(huì)給定子內(nèi)表面以較大的摩擦力,以致減弱了壓力反饋的作用。

2.葉片也有傾角,但傾斜方向正好與定量葉片泵相反,這是因?yàn)樽兞咳~片泵的葉片上下壓力是平衡的,葉片在吸油區(qū)向外運(yùn)動(dòng)主要依靠其旋轉(zhuǎn)時(shí)的離心慣性作用.根據(jù)力學(xué)分析,這樣的傾斜方向更有利于葉片在離心慣性作用下向外伸出。

3.變量葉片泵結(jié)構(gòu)復(fù)雜,輪廓尺寸大,相對(duì)運(yùn)動(dòng)的機(jī)件多,泄漏較大,軸上承受不平衡的徑向液壓力,噪聲較大,容積效率和機(jī)械效率都沒有定量葉片泵高;但是,它能按負(fù)載壓力自動(dòng)調(diào)節(jié)流量,在功率使用上較為合理,可減少油液發(fā)熱。

常用液壓名稱\名詞解釋

電磁閥（Electromagnetic valve）是用電磁控制的工業(yè)設(shè)備，是用來(lái)控制流體的自動(dòng)化基礎(chǔ)元件，屬于執(zhí)行器，并不限于液壓、氣動(dòng)。用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來(lái)實(shí)現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠保證。電磁閥有很多種，不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用，較常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。

電磁閥里有密閉的腔，在不同位置開有通孔，每個(gè)孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會(huì)被吸引到哪邊，通過控制閥體的移動(dòng)來(lái)開啟或關(guān)閉不同的排油孔，而進(jìn)油孔是常開的，液壓油就會(huì)進(jìn)入不同的排油管，然后通過油的壓力來(lái)推動(dòng)油缸的活塞，活塞又帶動(dòng)活塞桿，活塞桿帶動(dòng)機(jī)械裝置。這樣通過控制電磁鐵的電流通斷就控制了機(jī)械運(yùn)動(dòng)。

柱塞泵是液壓系統(tǒng)的一個(gè)重要裝置。它依靠柱塞在缸體中往復(fù)運(yùn)動(dòng)，使密封工作容腔的容積發(fā)生變化來(lái)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)，被廣泛應(yīng)用于高壓、大流量和流量需要調(diào)節(jié)的場(chǎng)合，諸如液壓機(jī)、工程機(jī)械和船舶中。機(jī)械分類 ? 軸向式 ? 直軸斜盤式  ? 徑向式 ? 液壓式 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。

比例閥 閥對(duì)流量的控制可以分為兩種：

一種是開關(guān)控制：要么全開、要么全關(guān)，流量要么較大、要么較小，沒有中間狀態(tài)，如普通的電磁直通閥、電磁換向閥、電液換向閥。

另一種是連續(xù)控制：閥口可以根據(jù)需要打開任意一個(gè)開度，由此控制通過流量的大小，這類閥有手動(dòng)控制的，如節(jié)流閥，也有電控的，如比例閥、伺服閥。

所以使用比例閥或伺服閥的目的就是：以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制（當(dāng)然經(jīng)過結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等），既然是節(jié)流控制，就必然有能量損失，伺服閥和其它閥不同的是，它的能量損失更大一些，因?yàn)樗�需要一定的流量�?lái)維持前置級(jí)控制油路的工作。

換向閥是具有兩種以上流動(dòng)形式和兩個(gè)以上油口的方向控制閥。是實(shí)現(xiàn)液壓油流的溝通、切斷和換向，以及壓力卸載和順序動(dòng)作控制的閥門。

可分為手動(dòng)換向閥、電磁換向閥、電液換向閥等。

又稱克里斯閥，閥門的一種，具有多向可調(diào)的通道，可適時(shí)改變流體流向。

工作時(shí)借著閥外的驅(qū)動(dòng)傳動(dòng)機(jī)構(gòu)轉(zhuǎn)動(dòng)驅(qū)動(dòng)軸，帶動(dòng)搖拐臂，啟動(dòng)閥板，使工作流體時(shí)而從左入口通向閥的下部出口，時(shí)而從右入口變換通向下部出口，實(shí)現(xiàn)了周期變換流向的目的。

這種變換閥在石油、化工生產(chǎn)中有著廣泛的應(yīng)用，在合成氨造氣系統(tǒng)中較為常用。此外，換向閥還可作成閥瓣式的結(jié)構(gòu)，多用于較小流量的場(chǎng)合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過閥瓣來(lái)變換工作流體的流向。

溢流閥是一種液壓壓力控制閥，在液壓設(shè)備中主要起定壓溢流作用，穩(wěn)壓，系統(tǒng)卸荷和安全保護(hù)作用。

主要作用編輯定壓溢流作用：在定量泵節(jié)流調(diào)節(jié)系統(tǒng)中，定量泵提供的是恒定流量。當(dāng)系統(tǒng)壓力加大時(shí)，會(huì)使流量需求減小。此時(shí)溢流閥開啟，使多余流量溢回油箱，保證溢流閥進(jìn)口壓力，即泵出口壓力恒定（閥口常隨壓力波動(dòng)開啟）。

節(jié)流閥是通過改變節(jié)流截面或節(jié)流長(zhǎng)度以控制流體流量的閥門。將節(jié)流閥和單向閥并聯(lián)則可組合成單向節(jié)流閥。節(jié)流閥和單向節(jié)流閥是簡(jiǎn)易的流量控制閥，在定量泵液壓系統(tǒng)中，節(jié)流閥和溢流閥配合，可組成三種節(jié)流調(diào)速系統(tǒng)，即進(jìn)油路節(jié)流調(diào)速系統(tǒng)、回油路節(jié)流調(diào)速系統(tǒng)和旁路節(jié)流調(diào)速系統(tǒng)。節(jié)流閥沒有流量負(fù)反饋功能，不能補(bǔ)償由負(fù)載變化所造成的速度不穩(wěn)定，一般僅用于負(fù)載變化不大或?qū)λ俣确�(wěn)定性要求不高的場(chǎng)合。

齒輪泵是依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動(dòng)來(lái)輸送液體或使之增壓的回轉(zhuǎn)泵。由兩個(gè)齒輪、泵體與前后蓋組成兩個(gè)封閉空間，當(dāng)齒輪轉(zhuǎn)動(dòng)時(shí)，齒輪脫開側(cè)的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側(cè)的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠?jī)蓚�(gè)齒輪的嚙合線來(lái)隔開的。齒輪泵的排出口的壓力完全取決于泵出處阻力的大小。

葉片泵因?yàn)闅v史的葉片泵根據(jù)中類型的不同有兩種

一）專門指容積泵中的滑片泵。

二）指動(dòng)力式泵的三泵（離心泵、混流泵、軸流泵）或其他特殊的泵。

這類泵產(chǎn)品一般不會(huì)叫葉片泵。但作為專著，葉片泵幾乎全部是指離心泵、混流泵、軸流泵等。

根據(jù)其每轉(zhuǎn)的理論排量是固定值還是可變值，可以分為葉片式變量泵和葉片式定量泵。

工作原理編輯葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí)，葉片在離心力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積，先由小到大吸油后再由大到小排油，葉片旋轉(zhuǎn)一周時(shí)，完成兩次吸油與排油。

單向閥是流體只能沿進(jìn)口流動(dòng)，出口介質(zhì)卻無(wú)法回流的裝置

單向閥 Check Valve 

單向閥又稱止回閥或逆止閥。用于液壓系統(tǒng)中防止油流反向流動(dòng),或者用于氣動(dòng)系統(tǒng)中防止壓縮空氣逆向流動(dòng)。

單向閥有直通式和直角式兩種。直通式單向閥用螺紋連接安裝在管路上。直角式單向閥有螺紋連接、板式連接和法蘭連接三種形式。液控單向閥也稱閉鎖閥或保壓閥，它與單向閥相同，用以防止油液反向流動(dòng)。但在液壓回路中需要油流反向流動(dòng)時(shí)又可利用控制油壓，打開單向閥，使油流在兩個(gè)方向都可流動(dòng)。液控單向閥采用錐形閥芯，因此密封性能好。在要求封閉油路時(shí)，可用此閥作為油路的單向鎖緊而起保壓作用。液控單向閥控制油的泄漏方式有內(nèi)泄式和外泄式二種。在油流反向出口無(wú)背壓的油路中可用內(nèi)泄式；否則需用外泄式，以降低控制油壓力。

壓力繼電器，液壓術(shù)語(yǔ)，是液壓系統(tǒng)中當(dāng)流體壓力達(dá)到預(yù)定值時(shí)，使電接點(diǎn)動(dòng)作的元件。

2.是將壓力轉(zhuǎn)換成電信號(hào)的液壓元器件，客戶根據(jù)自身的壓力設(shè)計(jì)需要，通過調(diào)節(jié)壓力繼電器，實(shí)現(xiàn)在某一設(shè)定的壓力時(shí)，輸出一個(gè)電信號(hào)的功能。
