液壓泵內(nèi)部結(jié)構(gòu)圖

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。

特點

鋁合金制造、強度高、耐腐蝕、重量輕、適合各種環(huán)境下作業(yè)。

雙速特性減少了打壓次數(shù)，在低壓室快速處于負(fù)載用功狀態(tài)，立刻轉(zhuǎn)換成高壓，縮短每次作業(yè)周期。

配有壓力調(diào)節(jié)閥，可調(diào)節(jié)控制及設(shè)定工作壓力。組成

液壓機械行業(yè)常會用到的葉片泵

聯(lián)軸器

1、聯(lián)軸器的選用

液壓泵傳動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)動軸和泵傳動軸。如因制造原因，泵與聯(lián)軸器同軸度超標(biāo)，裝配時又存在偏差，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)軸器柱銷松動未及時緊固、橡膠圈磨損未及時更換等影響因素。

2、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)動軸與泵端應(yīng)保持5～10mm距離；

挖掘機是工程機械主力機種，是建設(shè)工程的主要生產(chǎn)工具，因此對挖掘機提出了很高的要求。要求節(jié)能低排放、**率、良好的操縱性和降低對環(huán)境的負(fù)荷等，要實現(xiàn)這些要求必須對挖掘機進(jìn)行控制，由于液壓控制信息處理能力差，不能光靠液壓控制主要要靠電子控制。液壓動力由液壓泵提供，要知道液壓泵是挖掘機液壓系統(tǒng)的能源裝置，將電機的機械能轉(zhuǎn)換為液壓能，輸出流量和壓力，在液壓系統(tǒng)中占有非常重要的地位。如果液壓泵出現(xiàn)故障，將會影響到整個液壓系統(tǒng)的正常工作。

挖掘機液壓泵流量調(diào)整方法與壓力調(diào)整方法

一、液壓泵流量的調(diào)整

1、主泵流量的調(diào)整

(1)神鋼挖掘機200松開流量鎖緊螺母；

(2)轉(zhuǎn)動壓力調(diào)整螺栓，直到壓力符合規(guī)定為止；

(3)當(dāng)系統(tǒng)壓力在14700一17700kPa范圍內(nèi)時，順時針轉(zhuǎn)動流量調(diào)整螺栓1/4圈，流量增加約18L/min，此時較好級彈簧起作用。當(dāng)系統(tǒng)壓力在23500一34300kPa范鬧內(nèi)時，順時針轉(zhuǎn)動流量調(diào)整螺檢1/4圈，流量增加約7L/min，此時第二級彈簧起作用；

(4)若逆時針轉(zhuǎn)動流量調(diào)整螺栓，則流量減少相應(yīng)的數(shù)鎮(zhèn)；

(5)擰緊流量鎖緊螺母，擰緊力矩為(12加或減3)N?m；

(6)上泵和下泵流量的調(diào)整方法相同。

2、中聯(lián)205挖掘機主泵較大流量的調(diào)整

(1)松開流量鎖緊螺母；

(2)擰動流量調(diào)整螺栓，直到流量達(dá)到較大值為止。順時針轉(zhuǎn)動流量調(diào)整螺栓1/49，流量約減少13L/min。逆時針轉(zhuǎn)動流量調(diào)整螺栓1/4圈，流量約增加13L/min；

(3)擰緊流量鎖緊螺母，擰緊力矩為10N?m。

3、反流量的調(diào)整

(1)松開流量鎖緊螺母口；

(2)擰動流量調(diào)整螺栓，直到流量達(dá)到較大鎮(zhèn)為止。順時針轉(zhuǎn)動流量調(diào)整螺栓1/4W.在系統(tǒng)壓力為2500kPa時，流量約減少41./-n:逆nJ針轉(zhuǎn)動流量調(diào)整螺栓1/4圈，流量約增加4L/min；

(3)擰緊流量鎖緊螺母，擰緊力矩為(12加或減3)N?m。

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(jìn)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(jìn)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(dāng)這個封閉容積由小變大時進(jìn)行吸油，由大變小時進(jìn)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(jìn)時壓油。這種泵進(jìn)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%）。
