美國派克變量泵庫存                                                                                                                        美國派克變量泵齒輪采用具有九十年代先進(jìn)水平的新技術(shù)--雙圓弧正弦曲線齒型圓弧。它與漸開線齒輪相比，突出的優(yōu)點(diǎn)是齒輪嚙合中齒廓面沒有相對，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。該泵設(shè)計(jì)的，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。 泵設(shè)有差壓式閥作為超載保護(hù)，閥全回流壓力為泵額定壓力1.5倍。也可在允許壓力范圍內(nèi)根據(jù)實(shí)際需要另行。但是此閥不能作減壓閥長期工作，需要時(shí)可在管路上另行安裝。                                         PV032L1K1T1NFWS PV032R1K1B1NFDS PV032RAK1T1NFPV
