派克齒輪泵

派克齒輪采用具有九十年人*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(hù)要求確定。
parker齒輪油泵因受定排量的結(jié)構(gòu)限制，通常認(rèn)為齒輪泵僅能作恒流量液壓源使用。然而，附件及螺紋聯(lián)接組合閥方案對(duì)于提高其功能、降低系統(tǒng)成本及提高系統(tǒng)可靠性是有效的，因而，齒輪油泵的性能可接近價(jià)昂、復(fù)雜的柱塞泵。
在泵上直接安裝控制閥，可省去泵與方向閥之間管路，從而控制了成本。較少管件及連接件可減少泄漏，從而提高工作可靠性。而且泵本身安裝閥可降低回路的循環(huán)壓力，提高其工作性能。下面是一些可提高齒輪泵基本功能的回路，其中有些是實(shí)踐證明可行的基本回路，而有些則屬創(chuàng)新研究。
