簡介

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(jī)（如電動機(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、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。

液壓泵過度發(fā)熱有兩個原因：一是機(jī)械摩擦生熱。柱塞泵由于運(yùn)動表面處于干摩擦

或半干摩擦狀態(tài)，運(yùn)動部件相互摩擦生熱。二是液體摩擦生熱。高壓油通過各種縫隙泄漏到低壓腔，大量的液壓能損失轉(zhuǎn)為熱能；長期負(fù)荷過大導(dǎo)致卸荷閥頻繁開啟，油缸或閥有內(nèi)泄（閥內(nèi)部磨損，缸密封不好）；閥或管道有堵塞現(xiàn)象。所以正確選擇運(yùn)動部件之間的間隙、油箱容積和冷卻器，可以杜絕泵的過度發(fā)熱和油溫過高的現(xiàn)象。另外，回油過濾器堵塞造成回油背壓過高，也會引起油溫過高和泵體過熱。 

液壓泵轉(zhuǎn)速高，排油壓力高，工作環(huán)境惡劣，油液污染、油液選用不合規(guī)定或油液過少，都可造成泵損、泄漏。泵內(nèi)泄漏可使其功率損失加大，磨損嚴(yán)重。油液中侵入空氣后易于壓縮，可造成泵干磨。液壓泵內(nèi)長時間的泄漏、干磨或壓縮厲害， 必然發(fā)熱，引起油液升溫，造成系統(tǒng)發(fā)熱。 

變量液壓泵的伺服變量機(jī)構(gòu)損壞也會造成系統(tǒng)發(fā)熱，工作元件無力，或是系統(tǒng)過載,導(dǎo)致發(fā)動機(jī)、電動機(jī)悶車甚至停止工作 

伺服變量機(jī)構(gòu)損壞，假如不能變量了，必然導(dǎo)致系統(tǒng)高壓溢流，長期從而導(dǎo)致發(fā)熱！伺服變量機(jī)構(gòu)損壞有兩種表現(xiàn)：不變量，過早變量。不變量導(dǎo)致系統(tǒng)過載，因為此時變量泵相當(dāng)于定量泵。此時功率和壓力成正比；過早變量，相同的壓力時，系統(tǒng)流量變小，顯得工作元件無力，系統(tǒng)工作速度變慢。假如伺服閥不能換向了那么液壓泵就只能始終在較大排量下工作，

自然會發(fā)熱。定量泵 溢流閥。

挖掘機(jī)是工程機(jī)械主力機(jī)種，是建設(shè)工程的主要生產(chǎn)工具，因此對挖掘機(jī)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(shí)現(xiàn)這些要求必須對挖掘機(jī)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(jī)液壓系統(tǒng)的能源裝置，將電機(jī)的機(jī)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。
