齿轮泵的工作原理：
专业的讲，齿轮泵即正排量装置，像是缸筒内的活塞，当一个齿进入到另一个齿的流体空间之时，液体便将被挤排出来。由于液体的不可压缩性，使得液体与齿无法再同一时间占据同样的空间，如此，液体便被排出。基于齿相互咬合的连续性，液体被排出的现象也就呈连续，所以便在泵的出口
处提供了一个连续的排出量。当泵旋转时，所排出的量是一样的，只要驱动轴不断旋转，那么泵排出液体就不会停止，因此，泵流量的大小与转速有着直接的关系。齿轮泵结构简单，体积小，简单的说主要由两个尺寸相同的齿轮组成，重量轻。具有对油污的抗敏感，转速范围大，维护方便等优
良特性。
齿轮泵：由两个齿轮相互啮合在一起而构成的泵称为齿轮泵。它是依靠齿轮的轮齿啮合空间的容积变化来输送液体的，它属于回转泵，也可以认为属于容积泵。齿轮泵的种类较多。按啮合方式可以分为外啮合齿轮泵和内啮合齿轮泵；按轮齿的齿形可分为正齿轮泵、斜齿轮泵和人字齿轮泵等。
齿轮泵的工作原理及结构：
齿轮泵分为外齿轮泵。内齿轮泵。通过齿轮的啮合，形成局部的真空，从而不断地从油箱中吸油。外啮合齿轮泵是应用最广泛的一种齿轮油泵，一般齿轮泵通常指的就是外啮合齿轮泵。它的结构主要有主动齿轮、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。
齿轮泵主要由一对齿轮、外壳、泵盖、轴及轴承和密封盖板等组成。在泵体内有一对外啮合齿轮，齿轮两端面靠盖板密封，这样泵体，盖板和齿轮的各齿槽就形成多个密封腔，轮齿啮合线又将左右两密封腔隔开而形成吸、压油腔。当齿轮按图示方向旋转时，吸油腔（右侧）内的轮齿不断脱开啮合，使其密封容积不断增大而形成一定真空，在大气压力作用下从油箱吸进油液，随着齿轮的旋转，齿槽内的油液被带到压油腔（左侧）申压油腔内的轮齿不断进人啮合，使其密封容积不断减小，油液被压出。随着齿轮不停地旋转，齿轮泵就不断地吸油和排油。
