齿轮泵是依靠泵缸与啮合齿轮间所形成的工作容积变化和移动来输送液体或使之增压的回转泵。由两个齿轮、泵体与前后盖组成两个封闭空间，当齿轮转动时，齿轮脱开侧的空间的体积从小变大，形成真空，将液体吸入，齿轮啮合侧的空间的体积从大变小，而将液体挤入管路中去。吸入腔与排出腔是靠两个齿轮的啮合线来隔开的。齿轮泵的排出口的压力完全取决于泵出口处阻力的大小。

基本概念

齿轮泵的概念是很简单的，它的较基本形式就是两个尺寸相同的齿轮在一个紧密配合的壳体内相互啮合旋转，这个壳体的内部类似“8”字形，两个齿轮装在里面，齿轮的外径及两侧与壳体紧密配合。来自于挤出机的物料在吸入口进入两个齿轮中间，并充满这一空间，随着齿的旋转沿壳体运动，较后在两齿啮合时排出。

在术语上讲，齿轮泵也叫正排量装置，即像一个缸筒内的活塞，当一个齿进入另一个齿的流体空间时，因为液体是不可压缩的，所以液体和齿就不能在同一时间占据同一空间，这样，液体就被机械性地挤排出来。由于齿的不断啮合，这一现象就连续在发生，因而也就在泵的出口提供了一个连续排除量，泵每转一转，排出的量是一样的。随着驱动轴的不间断地旋转，泵也就不间断地排出流体。泵的流量直接与泵的转速有关。

驱动装置

齿轮泵由一个单独的电机驱动，可有效地阻断上游的压力脉动及流量波动。在齿轮泵出口处的压力脉动可以控制在1%以内。在挤出生产线上采用一台齿轮泵，可以提高流量输出速度，减少物料在挤出机内的剪切及驻留时间。

外啮合齿轮泵是应用较广泛的一种齿轮泵，一般齿轮泵通常指的就是外啮合齿轮泵。它的结构如图1所示，主要有主动齿轮、从动齿轮、泵体、泵盖和安全阀等组成。泵体、泵盖和齿轮构成的密封空间就是齿轮泵的工作室。两个齿轮的轮轴分别装在两泵盖上的轴承孔内，主动齿轮轴伸出泵体，由电动机带动旋转。外啮合齿轮泵结构简单、重量轻、造价低、工作可靠、应用范围广。

齿轮泵工作时，主动轮随电动机一起旋转并带动从动轮跟着旋转。当吸入室一侧的啮合齿逐渐分开时，吸入室容积加大，压力降低，便将吸人管中的液体吸入泵内；吸入液体分两路在齿槽内被齿轮推送到排出室。液体进入排出室后，由于两个齿轮的轮齿不断啮合，使液体受挤压而从排出室进入排出管中。主动齿轮和从动齿轮不停地旋转，泵就能连续不断地吸入和排出液体。

泵体上装有安全阀，当排出压力超过规定压力时，输送液体可以自动顶开安全阀，使高压液体返回吸入管。

型号 PGH 的液压泵是一种泄漏间隙补偿式拥有恒定排量的

内啮合齿轮泵。

它主要由泵体 (1.1)、轴承盖 (1.2)、内齿圈 (2)、小齿轮轴

(3)、滑动轴承 (4)、轴向板 (5)、端盖 (6)、安装法兰 (7) 和

止挡销 (8) ，以及配油组件 (9) 组成，其中配油组件由配油

盘 (9.1)、配油盘架 (9.2) 和密封辊 (9.3) 组成。

吸油和压油过程

液压动压支承的小齿轮轴 (3) 在所示的方向上驱动内齿

圈 (2) 。

在大约 90 ° 角的吸油区中的旋转运动过程中使吸油腔体积

加大。这样就形成一个负压而使油液流进吸油腔。

镰刀形的配油盘组件 (9) 将吸油腔和压油腔隔开。在压油腔

中，小齿轮轴 (3) 的齿重新进入齿圈 (2) 的齿间。液体通过

压力油通道 (P) 被挤出。

轴向补偿

轴向补偿力 FA 在压油区起作用，并且通过压力区 (10) 作用

于轴向板 (5)。

径向补偿

径向补偿力 FR 作用在配油盘 (9.1) 和配油盘架 (9.2)上。

由于工作压力的作用，配油盘 (9.1) 和配油盘架 (9.2) 压向小

齿轮轴 (3) 和内齿圈 (2) 的
