液壓泵內部結構圖SKF軸承在其使用過程中表現出很強的規律性，并且重復性非常好。正常優質不銹鋼軸承在開始使用時，振動和噪聲均比較小，但頻譜有些散亂，幅值都較小，可能是由于制造過程中的一些缺陷，如表面毛刺等所致。運動一段時間后，振動和噪聲維持一定水平，頻譜非常單一，僅出現二倍頻。極少出現三倍工頻以上頻譜，不銹鋼軸承狀態非常穩定，進入穩定工作期。繼續運行后進入使用后期，SKF軸承振動和噪聲開始增大，有時出現異音，但振動增大為初期故障。

濾油器的選用為大家介紹一下柴油發電機組緊固件組裝的具體注意事項，主要有一下幾個方面：1.氣缸蓋螺母的組裝擰緊氣缸蓋螺母時，應分數次逐步擰緊到規定的力矩，并按先中間、后兩邊、對角交叉的原則進行。拆缸時也應按規定順序逐步擰松。若氣缸蓋螺母擰緊得不均勻或不平衡，會引起缸蓋平面翹曲變形。若螺母擰得過緊，螺栓會拉伸變形，機體和螺紋也會受到損壞。若螺母擰得不夠緊，會造成氣缸漏氣、漏水、漏油，氣缸內的高溫氣體也會燒壞氣缸墊。飛輪螺母的組裝安裝時飛輪螺母必須擰緊，并用止推墊圈折邊鎖緊。如果飛輪螺母擰得不緊，柴油機工作時，會產生敲擊聲，嚴重時會損壞曲軸錐面，剪裂鍵槽，扭斷曲軸，造成嚴重事故。另外還要注意止推墊圈的角只能扳折一次。連桿螺栓的組裝用優質鋼材加工的連桿螺栓在工作中承受很大沖擊力，不能用普通螺栓代替。擰緊時扭力要均勻，兩根連桿螺栓要輪流分幾次逐步擰緊到規定力矩，最后用鍍鋅鐵絲鎖緊。若連桿螺栓扭緊力矩過大，會使螺栓拉伸變形甚至折斷，引起搗缸事故;若連桿螺栓擰緊力矩過小，軸瓦間隙增大，工作時產生敲擊聲和沖擊載荷，甚至發生燒瓦抱軸及連桿螺栓折斷事故。主軸承螺栓的組裝應保證主軸承的安裝精度，且不松動。擰緊主軸承螺栓時，5道主軸承應按照先中間，后4道，再5道的順序，分2～3次均勻擰緊到規定的力矩。每擰緊一道還應檢查一次曲軸轉動是否正常。主軸承螺栓擰緊力矩過大或過小所產生的危害，與連桿螺栓擰緊力矩過大或過小所產生的危害基本相同。平衡塊螺栓的組裝平衡塊螺栓安裝時應按順序，分幾次逐步擰緊到規定力矩。平衡塊應按原位裝復，否則會失去平衡作用。搖臂座螺母的組裝對于搖臂座螺母，在使用過程中要結合保養經常定期檢查。如果搖臂座螺母松動，會使氣門間隙增大，氣門開啟延后，關閉提前，氣門開啟延續時間縮短，引起柴油機供氣不足，排氣不凈，功率下降，油耗增加。噴油嘴鎖緊螺母的組裝在安裝噴油器時，其鎖緊螺母應擰緊到規定的力矩。同時，反復擰緊幾次，不要一次擰緊。若噴油嘴鎖緊螺母擰得過緊，會引起鎖緊螺母變形，還易使針閥卡死;若擰得過松，會引起噴油器漏油，噴油壓力下降，霧化不良，油耗增加。出油閥緊座的組裝安裝噴油泵的出油閥緊座時，也要按規定扭矩進行。若出油閥緊座擰得過緊，會使柱塞套筒變形，柱塞在套筒中發生阻滯現象，并引起柱塞偶件早期磨損，密封性能下降，功率不足;若出油閥緊座過松，會引起噴油泵漏油，不能建立油壓，供油時間滯后，供油量減少，嚴重影響發動機工作性能。噴油器壓板螺母的組裝。在柴油機氣缸蓋上安裝噴油器總成時，除了注意清除噴油器總成安裝座內積炭等臟物、噴油器總成壓板別裝反、鋼墊厚度要適當且不能漏裝外，還要注意噴油器總成壓板螺母的緊固力矩。
