齿轮油泵的安装
齿轮油泵的安装一定要按照产品说明书上的要求来进行。本文小编简单介绍齿轮油泵在安装与使用过程中要注意的细节与方法，总结出来有如下七点：
1.齿轮油泵紧固端面螺栓时，齿轮泵用力要对称均匀，边紧边盘动转子。若遇到卡涩，齿轮泵应松掉螺栓重新紧;
2.电泵的驱动轴与电机轴的连接采用弹性联轴器或链式联轴器;
3.齿轮泵驱动轴不能承受任何径向垂直力，皮带、链条、齿轮等侧向驱动方式禁止使用; 4.底板强度要够,不要时间长了,泵的底板一软,造成电机与泵不对中,而损坏泵;
5.弄清楚泵的允许高转速.和现场工作高转速;
6.务必让流体进到入口,尽量不要干转和空转;
7.齿轮油泵的进口与出口不要接反了.造成泵不出料来。
齿轮油泵效率
实际上，齿轮油泵内有很少量的流体损失，这使泵的运行效率不能达到，因为这些流体被用来润滑轴承及齿轮两侧，而齿轮油泵泵体也绝不可能无间隙配合，故不能使流体地从出口排出，所以少量的流体损失是必然的。然而泵还是可以良好地运行，对大多数挤出物料来说，仍可以达到93%～98%的效率。
齿轮油泵运转前，应将各油路调节阀松开，然后开动齿轮油泵，待空负荷运转正常后，再紧闭回油阀，逐渐旋拧进油阀杆，增大负荷，并注意压力表指针是否正常。
(1)齿轮泵容积效率。容积损失主要是通过齿轮端面与侧板间的轴向间隙，以及齿**与泵体内孔之间的径向间隙和齿侧接触线的泄漏损失，其中轴向间隙泄漏约占总泄漏量的75%-80%，一般轴向间隙0.03-0.04mm。齿轮容积效率一般为0.7-0.9.但小流量高压泵的效率低。
