A10VSO71DFR1/32R-VPB22U99 REXROTH柱塞泵

机械原理

吸油压油喷油泵的吸油和压油，由柱塞在柱塞套内的往复运动来完成。当柱塞位于下部位置时，柱塞套上的两个油孔被打开，柱塞套内腔与泵体内的油道相通，燃油迅速注满油室。当凸轮顶到滚轮体的滚轮上时，柱塞便升起。从柱塞开始间向上运动到油孔被柱塞上端面挡住前为止。在这一段时间内，由于柱塞的运动，燃油从油室被挤出，流向油道。所以这段升程称为预行程。当柱塞将油孔挡住时，便开始压油过程。柱塞上行，油室内油压急剧升高。当压力超过出油阀的弹簧弹力和上部油压时，就顶开出油阀，燃油压入油管送至喷油器。

油量调节

为了适应柴油机负载的要求，喷油泵的供油量必须能够在大供油量(全负荷)到零供油量(停车)的范围内进行调节。 供油量的调节是通过齿杆、转动套使喷油泵的全部柱塞同时转动来实现的。 当柱塞转动时，供油开始时间不变，而供油终了时间，则由于柱塞斜边对柱塞套回油孔位置的改变而变更了。随着柱塞转动的角度不同，柱塞的有效行程也就不同，因而供油量也随之改变。

柱塞对于不供油位1转动的角度越大，则柱塞上端面到打开拄塞套回油孔的斜边距离也越大，供油量也就越大，若柱塞转动的角度较小，则断油开始较早，供油量也较小。当柴油机停车时必须断油，为此，可将柱塞上的纵向槽转到正对着柱塞套上回油孔。此时，在整个柱塞行程中，柱塞套内的燃油一直通过纵向槽、回油孔流回油道，没有压油过程，故供油量等于零。

A10VSO 28…140系列柱塞变量泵

型斜盘结构轴向柱塞变量泵：

用于开式回路；

A10VSO轴向柱塞变量泵：

是用于液压开式回路的斜盘结构轴向柱塞变量泵。

A10VSO柱塞变量泵流量正比于驱动转速和排量，并能通过调节斜盘倾角实现无极变量。

A10VSO类型的变量柱塞泵适用于ISO标准的安装法兰，法兰连接符合SAE米制螺纹。

安装方式法兰：28/45/71/100规格常用作ISO2孔安装A，ISO4孔安装法兰140规格型安装用做B四个孔；

A10VSO柱塞变量泵的工作油口连接12型用于系列31，规格28/45/71/100/140，通轴驱动常用到N00不带通轴驱动，泵有通轴驱动可带轴向泵，齿轮泵，径向柱塞泵；

柱塞泵的泵油机构包括两套准确偶件：柱塞（plunger） 柱塞套(barrel)构成柱塞偶件(plunger and barrel assembly)（图5-11）、出油阀（delivery valve）和出油阀座(delivery valve seat)构成出油阀偶件(delivery valve assembly

柱塞和柱塞套是一对准确偶件，经配对研磨后不能互换，要求有高的精度和光洁度和好的耐磨性，其径向间隙为0.002～0.003mm

柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。

泵用安装体与电动机连接叶片泵与电动机（发动机）连接驱动时，要采用"安装体"结构，，其一端法兰与叶片泵的法兰连接，用4个（有的泵用2个）内六角螺钉紧固牢， 另一大端与V系列电动机B5或B35型的端法兰连接牢固，采用这种安装形式可使其两轴的同轴度不存在误差，其转动时也无噪声，是延长泵的使用寿命的理想途径。

液压系统按油液的循环方式，液压系统可分为开式系统和闭式系统。开式系统是指液压泵从油箱吸油，油经各种控制阀后，驱动液压执行元件，回油再经过换向阀回油箱。这种系统结构较为简单，可以发挥油箱的散热、沉淀杂质作用，但因油液常与空气接触，使空气易于渗入系统，导致机构运动不平稳等后果。开式系统油箱大，油泵自吸性能好。闭式系统中，液压泵的进油管直接与执行元件的回油管相连，工作液体在系统的管路中进行封闭循环。其结构紧凑，与空气接触机会少，空气不易渗入系统，故传动较平稳。工作机构的变速和换向靠调节泵或马达的变量机构实现，避免了开式系统换向过程中所出现的液压冲击和能量损失。但闭式系统较开式系统复杂，因无油箱，油液的散热和过滤条件较差。为补偿系统中的泄漏，通常需要一个小流量的补油泵和油箱。
