REXROTH齿轮泵PGH4-3X/050RE11VU2

齿轮泵按齿轮啮合形式分：

(l)外啮合式;(2)内啮合式。

外啮合齿轮泵的优点是结构简单、尺寸小、重量轻、制造维护方便、价格低廉、工作可靠、自吸能力强、对油液污染不敏感等。它的不足是齿轮承受不平衡的径向液压力，轴承磨损严重，泄漏量大。工作压力的提高受到径向液压力和容积效率的限制;流量脉动大，噪声高。

内啮合齿轮泵结构紧凑、尺寸小、重量轻。由于齿轮同向旋转，齿面相对滑动速度小、磨损轻微、使用寿命长、流量脉动远比外啮合齿轮泵小，因而噪声比较小。内啮合齿轮泵允许使用较高的转速，可获得较高的容积效率。但是内啮合齿轮泵同样存在着径向液压力不平衡的问题，限制了其工作压力的进一步提高。另外，齿轮泵的排量不可调节，在一定程度上限制了其使用的范围[2]。

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。

PGH.-3X型液压泵是具有恒定排量的间隙补偿内齿轮泵。

它们主要包括：安装法兰（1），壳体（2），带传动机构的盖（3），小齿轮轴（4），内齿轮（5），滑动轴承（6），轴向垫圈（7）和挡块销（8）以及由段（9），段支撑（10）和密封辊（11）组成的径向补偿。

吸移程序

液压安装的小齿轮轴（4）在所示的旋转方向上驱动带内齿轮的内齿轮（5）。

在吸入范围内打开的齿隙会吸入流体。流体从吸入范围（S）进入压力范围（P），被输送到小齿轮和内齿轮的齿隙中。

在那里，流体从闭合的齿隙中移出并输送到压力端口（P）中。

吸力和压力范围由径向补偿元件（9至11）以及内齿轮和小齿轮轴之间的齿啮合分开。

轴向补偿

压力范围内的位移区域由轴向垫圈（7）轴向密封。

在轴向垫圈的背离位移区域的侧面上施加压力场（12）。这些区域使轴向垫圈相对于位移区域保持平衡，从而实现了无缺的密封且机械损耗低。

齿轮泵工作原理:具有内齿的驱动齿轮（外转子）带动内转子在全封闭的泵体内作同方向转动，泵体和前盖的月牙板使吸入口和排出口隔开。转动时在吸入口形成负压，液体被吸入，转子将液体带到排出口，受压排出泵体，完成了液体的输送。泵主要有内外转子，轴，泵体，前盖，托架，密封，轴承等组成。密封农业生产体系械密封和填料密封两种形式，对于高温、高粘稠度及腐蚀性较强的介质，选用填料密封。输送易结晶物料时，在前盖和泵体上可设计带有保温夹套，工作时通蒸汽保温融化。泵可配安全阀，当泵或管路系统超压时，安全阀打开，形成内部回流保证系统安全

齿轮轴套与齿轮端面过度磨损，使卸压密封圈预压缩量不足而失去密封作用，导致油泵高压油腔与低压油腔串通，内漏严重。处理方法是：在后轴套下面加补偿垫片（补偿垫片厚度一般不宜超过2mm），保证密封圈安放的压缩量。
