REXROTH力士樂A10VSO系列柱塞泵特點:SAE和ISO的安裝法蘭;緊湊的結(jié)構(gòu);高的功率重量比;低噪聲;低壓力損失;短的控制時間;壓力和流量控制。排量為28140Vgcm3的泵額定壓力280bar,
高壓柱塞泵中往往在柱塞表面開有環(huán)行均壓槽,起均衡側(cè)向力﹑改善潤滑條件和存儲贓物的作用。均壓槽的尺寸常?。荷頷=0.3~0.7mm;間距t=2~10mm實際上,由于柱塞受到的徑向力很大,均壓槽的作用并不明顯,還容易滑傷缸體上柱塞孔壁面。因此,目前許多高壓柱塞泵中的柱塞不開設均壓槽。目前高壓柱塞泵已普遍采用帶滑靴的柱塞結(jié)構(gòu)。滑靴不僅增大了與斜盤的接觸面﹑減少了接觸應力,而且柱塞底部的高壓油液,經(jīng)柱塞中心孔 和滑靴中心孔 ,再經(jīng)滑靴封油帶泄露到泵殼體腔中。由于油液在封油帶環(huán)縫中的流動,使滑靴與斜盤之間形成一層薄油膜,大大減少了相對運動件間的摩擦損失,提高了機械效率。這種結(jié)構(gòu)能適應高壓力和高轉(zhuǎn)速的需要。
