style="margin:0px;padding:0px;text-decoration-line:none;color:#000000;"><strong style="margin:0px;padding:0px;">挖沙船</strong></a>過程中存在著一些看似正確實則錯誤的認識，這些錯誤認識導致的做法具有很大的危害性，會使挖沙船受到損害、人身安全受到威脅，甚至還可能會埋下安全隱患，或造成挖沙船性能下降、磨損加快、壽命縮短等。 </p> <p align="center" style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <img src="/uFile/90212/image/2019928131648286.jpg" alt="" /> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;">1、機油加得過多</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 當挖沙船機油不足時，軸承與軸頸等會發生潤滑不良，加劇磨損甚至引發燒瓦軸事故。但如果挖沙船機油太多，發動機同樣也要出故障，即在工作時曲軸柄、連桿大端會產生劇烈攪動，將增加挖沙船發動機內部功率損失，還會使濺到缸壁上的機油增多，產生燒排機油故障。因此，機油應控制在機油尺的上、下刻線之間為好。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;">2、盲目喜歡進口配件</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 有些挖沙船用戶特別喜歡“進口”配件，但適合歐洲配件在國內往往難有上佳表現，特別是有的配件特別“嬌氣”，容易引發事故。事實上，國產配件根據實際情況而生產的，更適合，價位更合理。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;"> 3、挖沙船內隨意增加各種設備</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 挖沙船整天在水里泥里的工作，對操作員來說追求挖沙船內舒適和豪華無可厚非，但在挖沙船內加裝各種設備，如果處理不妥當，會影響挖沙船性能及操縱，易留下后遺癥或影響操作安全。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;"> 4、盲目選擇潤滑油</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 潤滑油質量的好壞，直接關系到挖沙船發動機使用壽命的長短。尤其是新型挖沙船對潤滑油要求十分嚴格，選用什么潤滑油、如何更換等都應按照挖沙船廠家的規定進行。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 選用挖沙船發動機機油時，既要重視質量等級，也要注意粘度等級。首先應按壓縮比、排量等進行使用性能級別的選擇。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 然后按照氣溫、負荷進行粘度級別選擇。質量好的機油能保證發動機潤滑良好、減少磨損、減輕維護頻度和難度。在選擇機油粘度時，應該在保證發動機潤滑與密封的條件下，盡量選用低粘度機油，節約燃料。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;"> 5、盲目拆掉發動機節溫器</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 如果因挖沙船發動機溫度高而盲目拆除節溫器，冷卻液只能進行大循環，不能調節冷卻強度，難以保證發動機在較適宜的溫度下工作，反而使發動機經常處于低溫狀態下工作，造成挖沙船發動機功率下降，磨損加快，油耗增加。如果發動機節溫器發生故障檢修或更換之后，發動機溫度還高，就應檢修冷卻系統的其他部位，不能拆除節溫器。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> <span style="margin:0px;padding:0px;color:#0020FF;"> 6、長期不用挖沙船</span> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;font-family:"font-size:14px;white-space:normal;background-color:#FFFFFF;"> 以上就是關于<strong
