派克*齒輪泵/PARKER減壓閥
派克齒輪泵供應(yīng)商。我們公司是國外渠道直接廠家拿貨,貨到中國公司可提供報(bào)關(guān)單,本公司所有產(chǎn)品假一賠十!原裝產(chǎn)品派克齒輪泵,且合同注明假一賠十。

派克擁有八大性集團(tuán)組成:公司在其領(lǐng)域內(nèi)用于分別是運(yùn)動與控制集團(tuán)、過濾集團(tuán)、環(huán)境與工業(yè)控制CIC(Climate & Industrial Controls)、航天集團(tuán)、液壓產(chǎn)品、儀表管閥集團(tuán)、流體連接件集團(tuán)與密封集團(tuán)。

派克其儀器儀表的電磁閥共有四家個(gè)工廠:Lucifer (瑞士), Skinner, GoldRing, SCEM(意大利), 另有一家生產(chǎn)高品質(zhì)氣動膜片閥的工廠― Sinclair Collins。

派克漢尼汾流體傳動產(chǎn)品有限公司(Parker Hannifin)是的運(yùn)動和控制技術(shù)與系統(tǒng)多元化制造商,為廣泛的移動、工業(yè)和航空市場提供精準(zhǔn)解決方案。

保證*,票隨貨,我們公司在德國、美國都設(shè)有分公司,原廠家直接拿貨,空運(yùn)到中國,價(jià)格低貨期短。14年老公司信譽(yù)保證,只要你需要,我們將竭誠為你服務(wù)!

派克齒輪采用具有九十年人較高水平的新技術(shù)--雙圓弧正弦曲線齒型圓弧。它與漸開線齒輪相比,zui突出的優(yōu)點(diǎn)是齒輪嚙合過程中齒廓面沒有相對滑動,所以齒面無磨損、運(yùn)轉(zhuǎn)平衡、無困液現(xiàn)象,噪聲低、壽命長、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,于是總有兩對齒輪同時(shí)嚙合,并有一部分油液被圍困在兩對輪齒所圍成的封閉容腔之間。這個(gè)封閉的容腔開始隨著齒輪的轉(zhuǎn)動逐漸減小,以后又逐漸加大。封閉腔容積的減小會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)烈的振動和噪聲,這就是齒輪泵的困油現(xiàn)象。
