液压泵内部结构图SKF轴承在其使用过程中表现出很强的规律性，并且重复性非常好。正常优质不锈钢轴承在开始使用时，振动和噪声均比较小，但频谱有些散乱，幅值都较小，可能是由于制造过程中的一些缺陷，如表面毛刺等所致。运动一段时间后，振动和噪声维持一定水平，频谱非常单一，仅出现二倍频。极少出现三倍工频以上频谱，不锈钢轴承状态非常稳定，进入稳定工作期。继续运行后进入使用后期，SKF轴承振动和噪声开始增大，有时出现异音，但振动增大为初期故障。

滤油器的选用为大家介绍一下柴油发电机组紧固件组装的具体注意事项，主要有一下几个方面：1.气缸盖螺母的组装拧紧气缸盖螺母时，应分数次逐步拧紧到规定的力矩，并按先中间、后两边、对角交叉的原则进行。拆缸时也应按规定顺序逐步拧松。若气缸盖螺母拧紧得不均匀或不平衡，会引起缸盖平面翘曲变形。若螺母拧得过紧，螺栓会拉伸变形，机体和螺纹也会受到损坏。若螺母拧得不够紧，会造成气缸漏气、漏水、漏油，气缸内的高温气体也会烧坏气缸垫。飞轮螺母的组装安装时飞轮螺母必须拧紧，并用止推垫圈折边锁紧。如果飞轮螺母拧得不紧，柴油机工作时，会产生敲击声，严重时会损坏曲轴锥面，剪裂键槽，扭断曲轴，造成严重事故。另外还要注意止推垫圈的角只能扳折一次。连杆螺栓的组装用优质钢材加工的连杆螺栓在工作中承受很大冲击力，不能用普通螺栓代替。拧紧时扭力要均匀，两根连杆螺栓要轮流分几次逐步拧紧到规定力矩，最后用镀锌铁丝锁紧。若连杆螺栓扭紧力矩过大，会使螺栓拉伸变形甚至折断，引起捣缸事故;若连杆螺栓拧紧力矩过小，轴瓦间隙增大，工作时产生敲击声和冲击载荷，甚至发生烧瓦抱轴及连杆螺栓折断事故。主轴承螺栓的组装应保证主轴承的安装精度，且不松动。拧紧主轴承螺栓时，5道主轴承应按照先中间，后4道，再5道的顺序，分2～3次均匀拧紧到规定的力矩。每拧紧一道还应检查一次曲轴转动是否正常。主轴承螺栓拧紧力矩过大或过小所产生的危害，与连杆螺栓拧紧力矩过大或过小所产生的危害基本相同。平衡块螺栓的组装平衡块螺栓安装时应按顺序，分几次逐步拧紧到规定力矩。平衡块应按原位装复，否则会失去平衡作用。摇臂座螺母的组装对于摇臂座螺母，在使用过程中要结合保养经常定期检查。如果摇臂座螺母松动，会使气门间隙增大，气门开启延后，关闭提前，气门开启延续时间缩短，引起柴油机供气不足，排气不净，功率下降，油耗增加。喷油嘴锁紧螺母的组装在安装喷油器时，其锁紧螺母应拧紧到规定的力矩。同时，反复拧紧几次，不要一次拧紧。若喷油嘴锁紧螺母拧得过紧，会引起锁紧螺母变形，还易使针阀卡死;若拧得过松，会引起喷油器漏油，喷油压力下降，雾化不良，油耗增加。出油阀紧座的组装安装喷油泵的出油阀紧座时，也要按规定扭矩进行。若出油阀紧座拧得过紧，会使柱塞套筒变形，柱塞在套筒中发生阻滞现象，并引起柱塞偶件早期磨损，密封性能下降，功率不足;若出油阀紧座过松，会引起喷油泵漏油，不能建立油压，供油时间滞后，供油量减少，严重影响发动机工作性能。喷油器压板螺母的组装。在柴油机气缸盖上安装喷油器总成时，除了注意清除喷油器总成安装座内积炭等脏物、喷油器总成压板别装反、钢垫厚度要适当且不能漏装外，还要注意喷油器总成压板螺母的紧固力矩。
