安裝方式法蘭：28/45/71/100規(guī)格常用作ISO2孔安裝A，ISO4孔安裝法蘭140規(guī)格型安裝用做B四個(gè)孔；

A10VSO柱塞變量泵的工作油口連接12型用于系列31，規(guī)格28/45/71/100/140，通軸驅(qū)動(dòng)常用到N00不帶通軸驅(qū)動(dòng)，泵有通軸驅(qū)動(dòng)可帶軸向泵，齒輪泵，徑向柱塞泵；

系列：31，

公稱壓力/峰值壓力：280/350bar；

重量：15/21/33/45/60kg；

*流量：84/117156/200/252 L/min；

*轉(zhuǎn)速：3000/2600/2200/2000/1800min；

A10VSO型斜盤結(jié)構(gòu)軸向柱塞變量泵：此泵有兩個(gè)殼體的泄油孔，優(yōu)良的吸入性能；泵的連續(xù)壓力允許可達(dá)280bar；

泵的供油和自吸

油泵具有一定的自吸能力，但自吸的高度不宜超過500mm，并且嚴(yán)禁在吸入管道上安裝濾油器，吸入管道直徑不小于推薦數(shù)值，另外自吸時(shí)一定要把泵先調(diào)至全偏角。

在轉(zhuǎn)速超過1500rpm時(shí)，宜采用供油，供油壓力為0.7MPa左右。在開式系統(tǒng)中，供油泵的流量應(yīng)為該泵的130%，在閉式系統(tǒng)中，供油泵的流量應(yīng)為該泵的35%。

泵聯(lián)軸器的選用

液壓泵傳動(dòng)軸不能承受徑向力和軸向力，因此不允許在軸端直接安裝帶輪、齒輪、鏈輪，

通常用聯(lián)軸器聯(lián)接驅(qū)動(dòng)軸和泵傳動(dòng)軸。如因制造原因，泵與聯(lián)軸器同軸度超標(biāo)，裝配時(shí)又存在偏差，則隨著泵的轉(zhuǎn)速提高離心力加大聯(lián)軸器變形，變形大又使離心力加大。造成惡性循環(huán)，其結(jié)果產(chǎn)生振動(dòng)噪聲，從而影響泵的使用壽命。此外，還有如聯(lián)軸器柱銷松動(dòng)未及時(shí)緊固、橡膠圈磨損未及時(shí)更換等影響因素。

泵聯(lián)軸器的裝配要求

剛性聯(lián)軸器兩軸的同軸度誤差≤0.05mm

彈性聯(lián)軸器兩軸的同軸度誤差≤0.1mm

兩軸的角度誤差<1°；

驅(qū)動(dòng)軸與泵端應(yīng)保持5～10mm距離；

泵在試機(jī)運(yùn)行時(shí)應(yīng)注意事項(xiàng)：

1、安裝幫浦的軸心不得承受任何的徑向或是軸向壓力。

2、油泵啟動(dòng)前務(wù)必將油泵內(nèi)填滿液壓油后再進(jìn)行空載（無負(fù)載）運(yùn)轉(zhuǎn)，確認(rèn)液壓油有吸上來。

3、先試運(yùn)轉(zhuǎn)開關(guān)寸動(dòng)瞬間即停3-5次，確認(rèn)旋轉(zhuǎn)方向的正確性。

4、正式運(yùn)轉(zhuǎn)時(shí)必須800rmp-1000rpm，油泵內(nèi)部吸入油流速才能使泵內(nèi)部瞬間得到油的足夠量才不會(huì)使油泵內(nèi)零件磨損。

5、若運(yùn)轉(zhuǎn)時(shí)出現(xiàn)油流未正常流出即刻停止運(yùn)轉(zhuǎn)，就是因?yàn)楣苈穬?nèi)有空氣存在而產(chǎn)生真空現(xiàn)象，以致油泵不能順利將油供出。

6、若發(fā)現(xiàn)真空現(xiàn)象就要在油泵出油口或是進(jìn)入油路塊位置的油管適度放松，油泵再運(yùn)轉(zhuǎn)發(fā)現(xiàn)有油流出即可鎖死油管正式運(yùn)轉(zhuǎn)，這只是排除油管內(nèi)真空的一種方法。

7、先在無壓力下試運(yùn)轉(zhuǎn)3-5分鐘后漸進(jìn)加壓，調(diào)適30kg/㎡時(shí)在運(yùn)轉(zhuǎn)數(shù)分鐘， 70kg/㎡再試運(yùn)轉(zhuǎn)數(shù)分鐘，直至機(jī)臺(tái)使用*壓力為止。

8過濾網(wǎng)務(wù)必要使用150目及以上密度的規(guī)格，才適用在齒輪泵上。

9、以上步驟都確定完成后機(jī)臺(tái)即可正式運(yùn)行。

液壓泵是液壓系統(tǒng)的動(dòng)力元件，是靠發(fā)動(dòng)機(jī)或電動(dòng)機(jī)驅(qū)動(dòng)，從液壓油箱中吸入油液，形成壓力油排出，送到執(zhí)行元件的一種元件。液壓泵按結(jié)構(gòu)分為齒輪泵、柱塞泵、葉片泵和螺桿泵。

中文名液壓泵外文名 Hydraulic pumps 驅(qū) 動(dòng) 發(fā)動(dòng)機(jī)或電動(dòng)機(jī) 結(jié) 構(gòu) 齒輪泵、柱塞泵、葉片泵和螺桿泵性質(zhì) 一種液壓元件

液壓泵圖示符號

為液壓傳動(dòng)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(dòng)力機(jī)（如電動(dòng)機(jī)和內(nèi)燃機(jī)等）的機(jī)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(shè)計(jì)、制造因素外和一些與泵使用相關(guān)元件（如聯(lián)軸器、濾油器等）的選用、試車運(yùn)行過程中的操作等也有關(guān)系。

液壓泵的工作原理是運(yùn)動(dòng)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。

分類

常用液壓泵的種類：

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(yán)，價(jià)格較便宜；但泵軸受不平衡力，磨損嚴(yán)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(yùn)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(fù)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(fù)雜，材料和加工精度要求高、價(jià)格貴、對油的清潔度要求高。

一般在齒輪泵和葉片泵不能滿足要求時(shí)才用柱塞泵。還有一些其他形式的液壓泵，如螺桿泵等，但應(yīng)用不如上述3種普遍。
