力士樂柱塞泵REXTOTH葉片泵德國力士樂 PVV和PVQ泵是定排量葉片泵 

力士樂液壓泵特點
1）泵的流量正比于泵的轉(zhuǎn)速和排量，調(diào)節(jié)它的斜盤擺角可進行排量的無級調(diào)節(jié)
2）同軸結(jié)構(gòu)，可形成組合泵
3）位置約束回程結(jié)構(gòu)
4）球面配流，柱塞圍繞主軸傾斜布置
5）無級變量
6）優(yōu)良的吸入能力
7）控制相應時間短
8) 低噪音
9）長壽命
10）優(yōu)良的功率/重量比
11）模塊化設(shè)計
力士樂油泵在路面機械應用中涵蓋了壓路機，攤鋪機，路面冷熱器設(shè)備，在路面機械，

      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。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。
     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力。這就保證了轉(zhuǎn)子和柔性盤之間的*間隙，因而保證泵擁有的容積效率。
