style="text-indent:25px">液壓泵站的工作原理：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。液壓泵站根據(jù)工作原理可分為二種類型，具體如下。 1、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。外嚙合齒輪泵?當(dāng)齒輪旋轉(zhuǎn)時(shí)，在A腔，由于輪齒脫開使容積逐漸增大，形成真空從油箱吸油，隨著齒輪的旋轉(zhuǎn)充滿在齒槽內(nèi)的油被帶到B腔，在B腔，由于輪齒嚙合，容積逐漸減小，把液壓油排出?利用齒和泵殼形成的封閉容積的變化，完成泵的功能。 2、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，工作壓力和容積效率比齒輪泵高，結(jié)構(gòu)比齒輪泵復(fù)雜。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)，完成兩次吸油和兩次排油?利用插入轉(zhuǎn)子槽內(nèi)的葉片間容積變化，完成泵的作用。旭展移動(dòng)式液壓泵站規(guī)格液壓泵站漏油的原因:油溫太高。</p><div

1、吸油過濾器：吸過濾器的主要功能是過濾油液中的顆粒物質(zhì)。為防止過濾網(wǎng)的堵塞，采用了網(wǎng)式過濾，在正常的檢修中主要在注意過濾網(wǎng)的堵塞與漏氣，因?yàn)檫^濾網(wǎng)的堵塞會(huì)造成油泵的吸空。吸空會(huì)造成氣穴，而氣穴是液壓系統(tǒng)元件損壞的主要原因。同樣漏氣也會(huì)造成油泵的供給不足，所以使油泵產(chǎn)塞，降低油泵的容積，增加系統(tǒng)的流量損耗。 2、回油過濾器：回油過濾器主要由殼體，濾芯，旁路閥組成。它的主要功能是過濾工作介質(zhì)中的雜質(zhì)，提高系統(tǒng)壽命，在日常的維護(hù)中按時(shí)更換濾芯是減小設(shè)備故障率的辦法，如濾芯堵塞會(huì)造成系統(tǒng)背壓，指行元件的遲緩，系統(tǒng)的溫度升高，如果旁路閥打開，會(huì)造成過濾失敗，背壓油高速流過旁路閥會(huì)使油溫繼續(xù)升高，就將以前過濾下的雜質(zhì)沖進(jìn)油箱，同時(shí)使液壓油的空氣含量增加造成氣穴。</p><p style="text-indent:25px">液壓泵站的液壓系統(tǒng)壓力上不去的原因： 1、關(guān)閉油泵系統(tǒng)高壓出口閥門（一般都有此閥門，如沒有就要安裝一個(gè)），緩慢進(jìn)行升壓操作。 2、如果升壓正常，可以判定故障位置是后系統(tǒng)泄漏，如還不正常，就可以判定是油泵或溢流閥。 3、如懷疑溢流閥，就將溢流閥拆下清洗，有異物卡住內(nèi)部先導(dǎo)閥芯是常見的故障。 4、油泵故障可能性較小，一般是靠更換新泵的方法來排除。 5、后系統(tǒng)泄漏問題較難處理，需要分段隔離查找，來確定是換向閥還是液壓缸內(nèi)漏，但無論是誰，一般表現(xiàn)為閥體或油缸外壁溫度較高，甚至燙手。 6、換向閥內(nèi)漏，可以通過封閉AB口，用實(shí)驗(yàn)泵給高壓口打壓，觀察低壓口有無泄漏來判定。 7、油缸內(nèi)漏，可以通過用試驗(yàn)泵往其中一個(gè)油腔打壓，觀察另一個(gè)油腔是否有泄漏來判定（因?yàn)橛透谆钊荵X圈密封，還需要掉轉(zhuǎn)方向進(jìn)行測試一次）。液壓泵站液壓系統(tǒng)如何保養(yǎng)：用溫度計(jì)測量油溫。</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">如何來減少液壓油的污染程度呢?主要從以下幾方面入手：一、液壓油要定期更換，更換的標(biāo)準(zhǔn)，要根據(jù)使用情況來確定，一般不能超過三個(gè)月，更換液壓油時(shí)要順便沖洗油箱和油路管道等?！　?第二、液壓油的選擇也很重要，不同標(biāo)準(zhǔn)不同價(jià)格的液壓油本身的純凈度也是不一樣的，即使你把上面所說的各種措施都做好，可是液壓油自身就有雜質(zhì)，那么上面的工作做的再到位，也很難起到?jīng)Q定性的作用。有的液壓油只能用兩個(gè)月就必須更換了，有的液壓油則可以用半年以上，當(dāng)然，這并不是說純凈度越高的液壓油越適合我們，純凈度高價(jià)格也高啊，對液壓油的選擇要考慮到對壓力精度的需求，液壓泵壓力的大小等等，選擇一種性價(jià)比較高的液壓油就行了。液壓泵站設(shè)備維護(hù)及保養(yǎng)：定期檢查密封件，對液壓缸的密封件。旭展移動(dòng)式液壓泵站規(guī)格</p><p

style="text-indent:25px">在選擇過濾器時(shí)要各方面考慮流量因素，尤其是系統(tǒng)回油過濾器。一方面回油過濾器本身的實(shí)際流量不是恒定的，同時(shí)在一些季節(jié)溫差較大的地區(qū)液壓油本身的黏度會(huì)有較大的變化，如果**按照標(biāo)稱流量選擇會(huì)導(dǎo)致在冬季運(yùn)行設(shè)備時(shí)出現(xiàn)堵塞信號的發(fā)生，實(shí)際上并沒有出現(xiàn)堵塞甚至是新濾芯。因此，回油濾芯應(yīng)在核算流量的基礎(chǔ)上按照1.5倍以上的流量選擇。對于不采用單獨(dú)循環(huán)冷卻而利用主泵(一般是定量泵)卸載或系統(tǒng)回油冷卻的泵站，其回油濾芯成為控制系統(tǒng)清潔度的重要的元件，應(yīng)在流量、納污能力上預(yù)留充分的冗余，并采用雙筒過濾器以便于設(shè)備維護(hù)。旭展移動(dòng)式液壓泵站規(guī)格</p></p><br
