定量葉片泵 型號 PVV 

排量 18 至 193 ；元件系列: 1X ；最大工作壓力 210 bar ；最大擠壓容積 18 至 193 cm3

– 定排量

– 由于液壓卸荷的軸而使軸承擁有長壽命

– 由于液壓卸荷的葉片而僅有很小的磨損

– 工作噪音低

– 由于泵芯的互換性，有利于售后服務

– 好的效率

– 壓油口的位置可選

– 驅(qū)動轉(zhuǎn)向或右旋或左旋

– 驅(qū)動軸可選圓柱形或花鍵

雙聯(lián)泵：

– 極緊湊的結(jié)構(gòu)

– 壓油口的位置可分開選擇

PVV 和 PVQ 泵是定排量葉片泵。在驅(qū)動軸驅(qū)動軸 (1) 的齒上安裝有轉(zhuǎn)子 (2)，它在定子環(huán) (3) 內(nèi)回轉(zhuǎn)。葉片 (4) 安裝在轉(zhuǎn)子槽內(nèi)，轉(zhuǎn)子轉(zhuǎn)動時靠離心力使葉片壓在定子環(huán)的內(nèi)表面。排油腔的端面由配油盤 (5) 密封。由于

定子環(huán)是雙偏心結(jié)構(gòu)，因此形成對稱布置的兩個吸油區(qū)和兩個壓油區(qū)，因此傳動軸的徑向液壓力相互平衡而卸載。

由于 PVQ 泵的設(shè)計結(jié)構(gòu)，使其特別適用于行走機械應用。由于配油盤的特殊結(jié)構(gòu)，而能夠補償轉(zhuǎn)子體的熱膨脹和能夠?qū)ν蝗坏膲毫ψ兓鸬降挚棺饔谩Ｍㄟ^將配油盤分成柔性盤(7) 和端蓋 (8) 而形成反向壓力腔 (9)，以平衡在擠壓器中的壓軸僅傳遞驅(qū)動轉(zhuǎn)矩。在吸油區(qū)，葉片部分地卸荷。這能減少磨損和獲得高效率。取下端蓋 (6)，可以更換泵芯 (由轉(zhuǎn)子、葉片、定子環(huán)和配油盤組成)，而不必從鐘形罩上卸下泵體 (7)。這樣就能迅速地對泵進行維護和修理。力。這就保證了轉(zhuǎn)子和柔性盤之間的最佳間隙，因而保證泵擁有最好的容積效率。

結(jié)構(gòu) ；法蘭安裝按 SAE J744

油口 ；SAE 法蘭款式 (固定螺紋: UNC)

轉(zhuǎn)向 ；右旋或左旋

液流方向 ；進油口和壓油口不取決于轉(zhuǎn)向

安裝位置 ；任意，手選進油口在上面

驅(qū)動 ；直接，同軸驅(qū)動；不能傳遞軸向和徑向力
