派克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(lái)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(kāi)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?jī)蓚€(gè)齒輪的嚙合線來(lái)隔開(kāi)的。派克齒輪泵的排出口的壓力*取決于泵出處阻力的大小。
派克齒輪泵優(yōu)點(diǎn)
派克齒輪泵采用具有九十年人先進(jìn)水平的新技術(shù)--雙圓弧正弦曲線齒型圓弧。它與漸開(kāi)線齒輪相比,zui突出的優(yōu)點(diǎn)是齒輪嚙合過(guò)程中齒廓面沒(méi)有相對(duì)滑動(dòng),所以齒面無(wú)磨損、運(yùn)轉(zhuǎn)平衡、無(wú)困液現(xiàn)象,噪聲低、壽命長(zhǎng)、效率高。該泵擺脫傳統(tǒng)設(shè)計(jì)的束縛,使得齒輪泵在設(shè)計(jì)、生產(chǎn)和使用上進(jìn)入了一個(gè)新的領(lǐng)域。
派克齒輪泵設(shè)有差壓式安全閥作為超載保護(hù),安全閥全回流壓力為泵額定排出壓力1.5倍。也可在允許排出壓力范圍內(nèi)根據(jù)實(shí)際需要另行調(diào)整。但是此安全閥不能作減壓閥長(zhǎng)期工作,需要時(shí)可在管路上另行安裝。
該齒輪泵泵軸端密封設(shè)計(jì)為兩種形式,一種是機(jī)械密封,另一種是填料密封,可根據(jù)具體使用情況和用戶要求確定。
派克齒輪泵缺點(diǎn)
困油現(xiàn)象
派克齒輪泵要平穩(wěn)工作,齒輪嚙合的重合度必須大于1,于是總有兩對(duì)齒輪同時(shí)嚙合,并有一部分油液被圍困在兩對(duì)輪齒所圍成的封閉容腔之間。這個(gè)封閉的容腔開(kāi)始隨著齒輪的轉(zhuǎn)動(dòng)逐漸減小,以后又逐漸加大。封閉腔容積的減小會(huì)使被困油液受擠壓而產(chǎn)生很高的壓力,并且從縫隙中擠出,導(dǎo)致油液發(fā)熱,并致使機(jī)件受到額外的負(fù)載;而封閉腔容積的增大又造成局部真空,使油液中溶解的氣體分離,產(chǎn)生氣穴現(xiàn)象。這些都將產(chǎn)生強(qiáng)烈的振動(dòng)和噪聲,這就是齒輪泵的困油現(xiàn)象。
危害
徑向不平衡力很大時(shí)能使軸彎曲,齒頂與殼體接觸,同時(shí)加速軸承的磨損,降低軸承的壽命。
編輯本段消除困油現(xiàn)象方法
消除困油的方法,通常是在兩側(cè)蓋板上開(kāi)卸荷槽,使封閉腔容積減小時(shí)通過(guò)左邊的卸荷槽與壓油腔相通,容積增大時(shí)通過(guò)右邊的卸荷槽與吸油腔相通。
