派克油泵廠家報(bào)價(jià)
派克油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，較突出的優(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。
派克油泵設(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。
