                                                                                                                                                                      隨著我國鐵路運輸業的快速發展,對鐵路內燃機車的日常維護和故障診斷提出了更高的要求。 油品分析儀在鐵路內燃機車的監測和診斷中發揮著重要作用。

                                                                                                                                                                      據相關研究數據報告顯示,70%以上的機械設備故障是由磨損引起的。 世界上產生的能量約有1/3~1/2被摩擦損失所消耗。 隨著現代工業的快速發展,如何保證機械設備的安全穩定運行,減少故障的發生,降低維修成本成為必須解決的問題。 在科學合理的潤滑技術基礎上,建立機械設備磨損狀態監測與故障診斷技術,具有顯著的社會效益和經濟效益。 油液分析是最有效的無損檢測方法之一。

                                                                                                                                                                      油品分析儀在鐵路內燃機的磨損監測中已經應用了很長時間。 早期的油品分析儀只是常規分析潤滑油和在用潤滑油的理化指標,非常簡單。 隨著各類新技術的運用,鐵路正朝著重載、高速、自動化、高效的方向發展, 內燃機車的維護成本和停機損失也急劇增加, 傳統的計劃維護方式維護成本太高, 為了能最大限度地提高機車的使用效率, 鐵路系統逐步引進色譜、光譜、鐵譜等先進的油品分析儀器。


                                                                                                                                                                      這些儀器具有操作簡單、診斷方便、效率高、結果準確等優點, 已廣泛應用于內燃機故障診斷領域。

                                                                                                                                                                      下面我們來看看常用油品分析的內容和方法:
