武穴黎翔機(jī)電設(shè)備有限公司REXROTH力士樂(lè)銷售部
詢價(jià)聯(lián)系人:陳先生
廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域
力士樂(lè)REXROTH油泵特點(diǎn):力士樂(lè)柱塞泵根據(jù)傾斜元件的不同,有斜盤(pán)式和斜軸式兩種。斜盤(pán)式是斜盤(pán)相對(duì)
回轉(zhuǎn)的缸體有一傾斜角度,而引起柱塞在泵缸中往復(fù)
運(yùn)動(dòng)。傳動(dòng)軸軸線和缸體軸線是一致的。這種結(jié)構(gòu)較
簡(jiǎn)單,轉(zhuǎn)速較高,但工作條件要求高,柱塞端部與斜
盤(pán)的接觸部往往是薄弱環(huán)節(jié)。斜軸式的斜盤(pán)軸線
與傳動(dòng)軸軸線是一致的。它是由于柱塞缸體相對(duì)傳動(dòng)
軸傾斜一角度而使柱塞作往復(fù)運(yùn)動(dòng)。流量調(diào)節(jié)依靠擺
動(dòng)柱塞缸體的角度來(lái)實(shí)現(xiàn),故有的又稱擺缸式。它與
斜盤(pán)式相比,工作可靠,流量大,但結(jié)構(gòu)復(fù)雜。軸向柱塞泵與徑向柱塞泵比較,排出壓力高,它一般可在20~50MPa范圍內(nèi)工作,效率也高,徑向尺寸小、結(jié)構(gòu)緊湊、體積小、重量輕。但結(jié)構(gòu)較徑向柱塞泵復(fù)雜,加工制造要求高,價(jià)格較貴。軸向柱塞泵一般用
于機(jī)床、冶金、鍛壓、礦山及起重機(jī)械的液壓傳動(dòng)系
統(tǒng)中,特別廣泛地應(yīng)用于大功率的液壓傳動(dòng)系統(tǒng)中。
為了提高效率,在應(yīng)軸向柱塞泵一般都由缸體、配油
盤(pán)、柱塞和斜盤(pán)等主要零件組成。缸體內(nèi)有多個(gè)柱塞
,柱塞是軸向排列的,即柱塞的中心線平行于傳動(dòng)軸
的軸線,因此稱它為軸向柱塞泵。但它又不同于往復(fù)
式柱塞泵,因?yàn)樗闹粌H在泵缸內(nèi)做往復(fù)運(yùn)動(dòng),
而且柱塞和泵缸與斜盤(pán)相對(duì)有旋轉(zhuǎn)運(yùn)動(dòng)。柱塞以一球
形端頭與斜盤(pán)接觸。在配油盤(pán)上有高低壓月形溝槽,
它們彼此由隔墻隔開(kāi),*保*一定的密封性,它們分別
與泵的進(jìn)油口和出油口連通。斜盤(pán)的軸線與缸體
軸線之間有一傾斜角度。力士樂(lè)油泵有開(kāi)槽控制的斜盤(pán)設(shè)計(jì),連續(xù)可變的排量,良好的自吸性,
允許連續(xù)工作壓力350bar,低噪音,使用壽命長(zhǎng),驅(qū)
動(dòng)軸能吸收軸向和徑向載荷,模塊化設(shè)計(jì),通軸驅(qū)動(dòng)
控制時(shí)間短,泵位置可選,安裝位置也可以選擇,可
在降低的工作參數(shù)下用HFC液工作。力士樂(lè)油泵的控制方式有三種,壓力控制器(如A10VS045DR/31R-
PPA12NOO),還有就是壓力和流量控制器

比例閥采用閥芯+閥體結(jié)構(gòu)。伺服閥和伺服比例閥主要應(yīng)用在閉環(huán)控制系統(tǒng),比例閥的驅(qū)動(dòng)裝置是比例電磁鐵。
伺服閥的驅(qū)動(dòng)裝置是力馬達(dá)或力矩馬達(dá).閥體兼作閥套。
驅(qū)動(dòng)裝置不同.所以近些年出現(xiàn)了比例伺服閥。
比例閥一般*高幾十Hz,伺服閥中位沒(méi)有死區(qū),伺服閥對(duì)液壓油液的要求更高.性能參數(shù)不同;否則容易堵塞,
用來(lái)控制流量和流向,比例閥要求低一些.比例閥有中位死區(qū);
比例閥和伺服閥的區(qū)別主要體現(xiàn)在以下幾點(diǎn):
逐漸向伺服閥靠近,
比例換向閥屬于比例閥的一種,滯環(huán)、中位死區(qū)、頻寬、過(guò)濾精度等特性不同.閥的額定壓降不同;比例換向閥具有與普通換向閥相似的中位機(jī)能,
而比例伺服閥性能介于伺服閥和比例閥之間,因此應(yīng)用場(chǎng)合不同,伺服閥和伺服比例閥采用閥芯+閥套的結(jié)構(gòu)。中位機(jī)能種類不同.其它結(jié)構(gòu)的比例閥主要應(yīng)用在開(kāi)環(huán)控系統(tǒng)及閉環(huán)速度控制系統(tǒng);因?yàn)楸壤y的性能越來(lái)越好;2伺服閥的頻響(響應(yīng)頻率)更高。閥芯結(jié)構(gòu)及加工精度不同.伺服閥與比例閥之間的差別并沒(méi)有嚴(yán)格的規(guī)定。
,可以高達(dá)200Hz左右,需要精過(guò)濾才行,而伺服閥中位機(jī)能只有O型(Rexroth產(chǎn)品的E型)。
