1、機油加得過多
　當(dāng)機油不足時，軸承與軸頸等會發(fā)生潤滑不良，加劇磨損甚至引發(fā)燒瓦軸事故。但機油太多，發(fā)動機同樣也要出故障，即在工作時曲軸柄、連桿大端會產(chǎn)生劇烈攪動，將增加發(fā)動機內(nèi)部功率損失，還會使濺到缸壁上的機油增多，產(chǎn)生燒排機油故障。因此，機油應(yīng)控制在機油尺的上、下刻線之間為好。
　2、盲目喜歡進口配件
　有些抽沙船用戶特別喜歡“進口”配件，但適合歐洲配件在國內(nèi)往往難有上佳表現(xiàn)，特別是有的配件特別“嬌氣”，容易引發(fā)事故。事實上，國產(chǎn)配件根據(jù)實際情況而生產(chǎn)的，更適合，價位更合理。

1, add too much oil
When the oil is insufficient, bearing and shaft neck will happen to bad lubrication, wear even cause the burning bearing accident. But too much oil, the engine also have a fault, in which the crankshaft work handle, connecting rod will churn, will increase the power loss inside the engine, will make the splash onto the wall of oil increases, resulting in burning oil discharge fault. Therefore, the oil should be controlled between the oil feet, under the line as well.
2, blindly like imported accessories
Some users love special pumping sand imported parts, but for Europe parts in the country are often difficult to have a good performance, especially in some special parts "fragile", easily lead to accidents. In fact, the domestic parts produced according to the actual situation, more suitable, more reasonable price.
