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。

齿轮泵的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。

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。

泵的齿轮与轴共为一体，采用通体淬硬工艺，可获得更长的工作寿命。“D”型轴承结合了强制润滑机理，使聚合物经轴承表面，并返回到泵的进口侧，以确保旋转轴的有效润滑。这一特性减少了聚合物滞留并降解的可能性。准确加工的泵体可使“D”型轴承与齿轮轴较好配合，确保齿轮轴不偏心，以防止齿轮磨损。

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，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。

内啮合齿轮泵，它由一对相互啮合的内齿轮及它们中间的月牙形件、泵壳等构成。月牙形件的作用是将吸入室和排出室隔开。当主动齿轮旋转时，在齿轮脱开啮合的地方形成局部真空，液体被吸入泵内充满吸入室各齿间，然后沿月牙形件的内外两侧分两路进入排出室。在轮齿进入啮合的地方，存在于齿间的液体被挤压而送进排出管。

齿轮泵除具有自吸能力、流量与排出压力无关等特点，泵壳上无吸入阀和排出阀，具有结构简单，流量均匀、工作可靠等特性，但效率低、噪音和振动大、易磨损，主要用来输送无腐蚀性、无固体颗粒并且具有润滑能力的各种油类，温度一般不超过70 ℃，例如润滑油、食用植物油等。一般流量范围为0.045～30ms/h，压力范围为0.7—20MPa，工作转速为1200—4000r/min。
