Rexroth内啮合齿轮泵PGH型经销

力士乐定量内啮合齿轮泵的特点：定排量；低噪声；低的流量脉动；由于采用间隙密封的补偿即使在低速和低粘度油液时也有高的效率；适用于广范围的各种粘度和转速；所有规格可自由组合组成组合泵；能和PGF型内齿轮泵、轴向柱塞泵和叶片泵组成多联泵
Rexroth定量内啮合齿轮泵的工作原理：
流入和排出原理
支承在油膜轴承上的带轴外齿轮驱动内齿轮以一定的方向转动。转动时，在约90 e范围的吸油区内体积增加。产生吸力，流体进入吸油区。
月牙形的弧形元件将吸油腔和排油腔隔开。在排油腔外齿轮的齿和内齿轮齿啮合，流体
就从排油腔排出。
轴向间隙补偿
轴向补偿力FA由前、后盖间的压力场产生，作用在排油腔内的轴向浮动板上。由于工作压力的作用，这两个弧形元件和压向外齿轮的齿顶。弧形体和弧形支架的面积比和密封圈的位置设计得使内齿轮、弧形体和外齿轮之间达到可靠的密封。
弹性元件密封圈能保证即使在很低的压力下这些元件间也有适当的接触压力。
液*承和油膜轴承
作用在带轴外齿轮上的力由油膜润滑的径向滑动轴承承受；作周在内齿轮上的力由静*承。两个齿轮均为渐开线式齿轮道具加工，较长的啮合长度使泵的排量和压力脉动较小。这使泵的运行噪声大大降低。
德国Rexroth力士乐PGH型液压泵是泄漏间隙补偿结构的定排量内啮合齿轮泵。它的主要组成部分有泵体，轴承，内齿轮，带轴外齿轮，滑动轴承，前、后盖，端盖，安装法兰，和定位销以及由弧形体支架和密封垫组成的弧形元件。
