力士樂柱塞泵A10VSO28DFR1/31R-VPA12N00現(xiàn)貨
力士樂變量柱塞泵是往復(fù)泵的一種,屬于體積泵,在其工作時(shí)。它的柱塞靠泵軸的偏心轉(zhuǎn)動(dòng)驅(qū)動(dòng),往復(fù)運(yùn)動(dòng),其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時(shí),工作室內(nèi)壓力降低,出口閥關(guān)閉,低于進(jìn)口壓力時(shí),進(jìn)口閥打開,液體進(jìn)入;柱塞內(nèi)推時(shí),工作室壓力升高,進(jìn)口閥關(guān)閉,高于出口壓力時(shí),出口閥打開,液體排出。"
A10VSO系列斜盤結(jié)構(gòu)變量柱塞泵,用于驅(qū)動(dòng)開式回路液壓傳動(dòng),其容積流量取決于驅(qū)動(dòng)轉(zhuǎn)速和泵的排量,調(diào)節(jié)斜盤的位置可無級(jí)地改變泵的流量。
排量為28…140 Vg cm3的泵額定壓力280 bar,峰值壓力350 bar。
特點(diǎn):
用于液壓開式回路的斜盤結(jié)構(gòu)軸向柱塞變量泵;
流量正比于驅(qū)動(dòng)轉(zhuǎn)速和排量,并能通過調(diào)節(jié)斜盤傾角實(shí)現(xiàn)無級(jí)變量;
ISO標(biāo)準(zhǔn)的安裝法蘭;
法蘭連接符合SAE米制;
有兩個(gè)殼體泄油孔;
優(yōu)良的吸入性能;
允許連續(xù)運(yùn)行壓力可達(dá)280 bar;
低噪聲;
長(zhǎng)壽命;
驅(qū)動(dòng)軸能承受軸向及徑向負(fù)載;
高的功率/重量比;
廣范圍的多種控制形式;
控制響應(yīng)時(shí)間短;
采用通軸結(jié)構(gòu),可用于多回路系統(tǒng)
