單作用葉片泵

單作用葉片泵的定義:葉片在離力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上。通過改變兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積大小變化，完成吸油排油過程，且葉片旋轉(zhuǎn)一周，完成一次吸油與排油的葉片泵。

特點(diǎn): 

1.泵每轉(zhuǎn)一轉(zhuǎn)，每個(gè)密封腔吸油壓油一次

2.轉(zhuǎn)子上受液壓不平衡力，為非平衡式泵

3.改變偏心距大小，可改變排量，為變量泵

單作用葉片泵的工作原理

泵由轉(zhuǎn)子1、定子2、葉片3、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)，右側(cè)的葉片向外伸出，密封工作腔容積逐漸，產(chǎn)生真空，于是通過吸油口和配油盤上窗口將油吸入。而在圖的左側(cè)。葉片往里縮進(jìn)，密封腔的容積逐漸縮小，密封腔中的油液經(jīng)配油盤另一窗口和壓油口1被壓出而輸出到系統(tǒng)中去。

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。

液壓泵調(diào)整方法.液壓泵較大流量的調(diào)整方法松開調(diào)節(jié)器鎖緊螺母，并調(diào)整螺釘，順時(shí)針調(diào)整為加大流量，逆時(shí)針調(diào)整為減少流量。較大流量調(diào)整時(shí)，調(diào)整螺釘不能大于圈。.液壓泵較小流量調(diào)整方法松開調(diào)節(jié)器鎖緊螺母，并調(diào)整螺釘，順時(shí)針調(diào)整為減小流量，逆時(shí)針調(diào)整為加大流量。較小流量調(diào)整時(shí)，要求轉(zhuǎn)動(dòng)調(diào)整螺釘不能大于圈。.液壓泵扭矩調(diào)整方法松開調(diào)節(jié)器鎖緊螺母，并調(diào)整螺釘，順時(shí)針調(diào)整則扭矩加大，逆時(shí)針調(diào)整則扭矩減小。同樣松****緊螺母，并調(diào)整螺釘0，順時(shí)針調(diào)整扭矩加大，逆時(shí)針調(diào)整扭矩減小。

葉片泵用安裝體與電動(dòng)機(jī)連接葉片泵與電動(dòng)機(jī)（發(fā)動(dòng)機(jī)）連接驅(qū)動(dòng)時(shí)，要采用"安裝體"結(jié)構(gòu)，如圖1-8所示，其一端法蘭與葉片泵的法蘭連接，用4個(gè)（有的泵用2個(gè)）內(nèi)六角螺釘緊固牢， 另一大端與V系列電動(dòng)機(jī)B5或B35型的端法蘭連接牢固，采用這種安裝形式可使其兩軸的同軸度不存在誤差，其轉(zhuǎn)動(dòng)時(shí)也無噪聲，是延長泵的使用壽命的理想途徑。

葉片泵的輸人軸不能承受軸向力和徑向力，因此安裝聯(lián)軸器時(shí)，不準(zhǔn)用鐵捶敲打裝配，聯(lián)軸器內(nèi)孔采用二級(jí)間隙配合為宜，在鍵槽180°方向鉆一個(gè)M6-M10mm的螺紋孔，用螵釘止住防止竄動(dòng)。

采用腳架式葉片泵時(shí)，嚴(yán)禁用帶輪或鏈輪直接傳動(dòng)，亦要用聯(lián)軸器與驅(qū)動(dòng)機(jī)軸連接，兩個(gè)軸的同軸度誤差應(yīng)控制在0.05-0.1mm以內(nèi)，角度誤差不大于0.5°，兩軸間應(yīng)留有3mm 距離。

液壓配管

(1)根據(jù)壓力及使用場合選擇油管,油管須有足夠的強(qiáng)度,內(nèi)壁應(yīng)光滑、清潔,無沙、無銹、無氧化皮,對(duì)于長期貯存的管子,加工前應(yīng)酸洗,完全清洗、沖刷,并進(jìn)行檢查。

(2)用鋸切斷管子時(shí),斷面與軸線方向的不垂直度應(yīng)為±0.5°,銳邊須倒鈍并清除鐵屑,加工彎曲管時(shí)允許其斷面的橢圓度為10%。當(dāng)其外徑<14mm時(shí)可用手和一般工具彎管,較粗鋼管宜用手動(dòng)或機(jī)動(dòng)的彎管機(jī)彎管,彎管半徑一般應(yīng)比管子外徑大3倍。

(3)安裝管路要求是,線路較短,轉(zhuǎn)彎盡可能要少,管路的較高部分應(yīng)設(shè)排氣裝置,以便啟動(dòng)時(shí)放氣。

(4)安裝橡膠管時(shí),應(yīng)避免急轉(zhuǎn)彎,其彎曲半徑R≥(9~l0)D(D為軟管外徑)。不要在靠近接頭根部折彎,要求軟管接頭至開始彎曲處的距離L≥6D。軟管工作時(shí)不應(yīng)扭轉(zhuǎn)。

(5)吸油管不得漏氣,也不應(yīng)阻力太大,以防進(jìn)氣或吸油困難產(chǎn)生氣蝕。

(6)回油管口須伸到油箱油面以下,防止飛濺產(chǎn)生氣泡。溢流閥的回油管不能直接和泵的入口連通,一定要通過油箱,否則油溫將會(huì)過高。

(7)全部管路安裝程序分兩次進(jìn)行,先進(jìn)行試裝配,將管接頭及法蘭點(diǎn)焊在合適位置上,當(dāng)全部管路試裝合格后,拆下來進(jìn)行酸洗后再正式安裝。

液壓元件安裝

(1)所有液壓元件都要進(jìn)行壓力和密封試驗(yàn),合格后方可安裝。安裝前應(yīng)將各種自動(dòng)控制儀表進(jìn)行校驗(yàn),以免失誤。

(2)安裝各種控制閥時(shí),應(yīng)注意其進(jìn)油口與回油口的方位。用法蘭安裝閥類件時(shí)螺釘不能擰得過緊,過緊有時(shí)反而會(huì)造成密封不良。

(3)安裝液壓缸應(yīng)牢固可靠,為防止熱膨脹影響,當(dāng)行程大和溫度高時(shí),缸的一端必須保持浮動(dòng)。液壓缸的密封圈不要太緊,特別是U形圈,以免阻力過大。

(4)液壓泵傳動(dòng)軸與電動(dòng)機(jī)驅(qū)動(dòng)軸不同軸度偏差應(yīng)小于0.lmm,一般采用撓性聯(lián)軸節(jié)連接,不允許用膠帶直接帶動(dòng)泵軸轉(zhuǎn)動(dòng),以防泵軸受徑向力過大,影響泵的正常運(yùn)轉(zhuǎn)。

(5)安裝液壓泵時(shí)其旋轉(zhuǎn)方向和進(jìn)、出油口應(yīng)符合技術(shù)要求。

(6)各類液壓泵的吸油高度,一般小于0.5mm。

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�需要一定的流量來維持前置級(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合。工作時(shí)只需轉(zhuǎn)動(dòng)手輪通過閥瓣來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兩個(gè)齒輪的嚙合線來隔開的。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，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。
