A10VSO型號(hào)(32系列)四孔安裝力士樂(lè)柱變量泵 力士樂(lè)比例閥,比例流量閥 REXROTH液壓閥據(jù)悉,REXROTH不僅是世界*強(qiáng)公司,也是比較有名高科技企業(yè)之一,50多年來(lái),BoschRexroth集團(tuán)及BoschRexroth公司的業(yè)務(wù)部門(mén)致力開(kāi)發(fā)專(zhuān)業(yè)型液壓傳動(dòng)領(lǐng)域高科技產(chǎn)品,產(chǎn)品和品牌已享譽(yù)。原裝力士樂(lè)柱塞泵,Rexroth葉片泵上?,F(xiàn)貨德國(guó)力士樂(lè)柱塞泵A10VSO71DR/31R-PPA12N00
就核心組成部件齒輪而言主要由公法線(xiàn)齒輪泵和圓弧齒輪泵。公法線(xiàn)齒輪泵輸送含雜質(zhì)的介質(zhì)比圓弧齒輪泵要耐用,而圓弧齒輪泵結(jié)構(gòu)特殊,輸送干凈的介質(zhì)噪音低,壽命長(zhǎng),各有各的優(yōu)點(diǎn)。
博世力士樂(lè)比例閥REXROTH力士樂(lè)比例閥閥對(duì)流量的控制可以分為兩種:
一種是開(kāi)關(guān)控制:要么全開(kāi)、要么全關(guān),流量要么zui大、要么zui小,沒(méi)有中間狀態(tài),如普通的電磁直通閥、電磁換向閥、電液換向閥。力士樂(lè)比例閥,比例流量閥 REXROTH液壓閥
另一種是連續(xù)控制:閥口可以根據(jù)需要打開(kāi)任意一個(gè)開(kāi)度,由此控制通過(guò)流量的大小,這類(lèi)閥有手動(dòng)控制的,如節(jié)流閥,也有電控的,如比例閥、伺服閥。
所以使用比例閥或伺服閥的目的就是:以電控方式實(shí)現(xiàn)對(duì)流量的節(jié)流控制(當(dāng)然經(jīng)過(guò)結(jié)構(gòu)上的改動(dòng)也可實(shí)現(xiàn)壓力控制等),既然是節(jié)流控制,就必然有能量損失,伺服閥和其它閥不同的是,它的能量損失更大一些,因?yàn)樗枰欢ǖ牧髁縼?lái)維持前置級(jí)控制油路的工作。
