齿轮泵的缺点不适用于输送含有固体颗粒的液体及高挥发性低闪点的液体;长期运行时泵内的齿轮容易磨损;输送介质流量较小。

PGH4-3X/032RE11WE4齿轮泵工作时,在齿轮和轴承上承受径向液压力的作用。泵的右侧为吸油腔,左侧为压油腔。在压油腔内有液压力作用于齿轮上,沿着齿顶的泄漏油,具有大小不等的压力,就是齿轮和轴承受到的径向不平衡力。液压力越高,这个不平衡力就越大,其结果不仅加速了轴承的磨损,降低了轴承的寿命,甚至使轴变形,造成齿顶和泵体内壁的摩擦等。为了解决径向力不平衡问题,在有些齿轮泵上,采用开压力平衡槽的办法来消除径向不平衡力,但这将使泄漏增大,容积效率降低等。CB—B型齿轮泵则采用缩小压油腔,以减少液压力对齿顶部分的作用面积来减小径向不平衡力,所以泵的压油口孔径比吸油口孔径要小。
