     噪音常见问题及解决方法：

    1.油泵内存有空气。这个故障一般是在安装了一台新泵的时候出现，在开起一台新泵时，应先向泵内加入油液，对泵的轴承、柱塞与缸体起到润滑作用；

    *处理方法：在泵运转时打开油泵加油口，使泵内的空气从加油口排放出去。

2.油箱的油面过低。吸油管堵塞使得泵吸油阻力变大造成泵吸空或进油管段有漏气，泵吸入了空气；

*处理方法：按规定加足油液；清洗滤清器，疏通进气管道；检查并紧固进油管段的连接螺丝。

3.油泵与电机安装不当，也就是说泵轴与电机轴同心度不*，使油泵轴承受径向力产生噪声； 

*处理方法：检查调整油泵与电机安装的同心度。

4.液压油的粘度过大，使得泵的自吸能力降低，容积效率下降；

*处理方法：选用适当粘度的液压油，如果油温过低应开启加热。
