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，吸入室容积增大，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，便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。

排量、流量
排量是指泵（或马达）每转一周，由密封容腔几何尺寸变化而得的排出（或输入）液体的体积，常用单位是ml/r（毫升/转）。排量可以通过调节发生变化的成为变量泵（或变量马达），排量不能变化的成为定量泵（或定量马达）。
实际流量是指泵（或马达）工作时出口处（或进口处）的流量。由于泵本身存在内泄漏，其实际流量小于理论流量。由于马达本身也存在内泄漏，要实现指定转速，为补偿泄漏量，其输入实际流量必须大于理论流量。

柱塞和柱塞套是一对精密偶件，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。

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处阻力的大小。

效率
容积效率，对液压泵是指其实际流量与理论流量的比值。对液压马达是指其理论流量与实际流量的比值。
机械效率，对液压泵是指其理论转矩与实际输入转矩的比值。对液压马达其实际输出的转矩为理论转矩克服摩擦力后的转矩，因此其机械效率为实际输出转矩与理论转矩的比值。
总效率是指泵（或马达）的输出功率与输入功率的比值。总效率等于容积效率与机械效率的乘积。
