鹤岗干式变压器滤清器变形有什么影响？

(1)故障现象 一台6CTA8.3型机大修后试机时，发现急速和全速工作运行状态下，润滑油压力均偏低，调整机油压力调节阀时，压力变化不大。(2)故障查找分析 由于在大修过程中对机油泵、散热器、机油弗列加滤清器，机油冷却器本部件及油道进行了检查和仔细的清洗，对旁通阀、压力调节阀和节温器也进行了试验，均工作运行正常。而且连杆轴瓦与轴颈等部件的配合间隔也在公差范围内，所以基本排除以上部件的故障。检查了机油压力传感器和压力表，并且对各接线进行了紧固后，开机检查时故障仍未排除，但是发现机油压力传感器松开后与机体连接处润滑油涌出量较少，所以故障可能是机油泵吸入油量不足或者润滑油道泄漏严重。根据以上分析，首先对集滤器进行检查。卸掉油底売，拿出集滤器后发现滤网被压扁，而油底壳和滤网对应处严重变形，这显然是由于吊装机器时不慎将油底壳碰撞后凹陷所至、，滤网变形后，机油泵吸入油量过小而导致润滑油压力过低。(3)故障排除 更换滤网，并将油底壳敲平后故障排除。
