            挖掘機使用中的常見的不良陋習?

            日期:2018-07-26   來源:http://www.idsashop.com/
            一、水箱開鍋加冷水
            First, water tank opening and cold water
            在挖掘機發動機超負荷作業、散熱不好等情況都會造成水箱開鍋的狀況。很多修理工的反應是加水。但是,如果這個時候加冷水就會造成缸蓋和缸體炸裂,所以這個時候應該先停止發動機,等其自然冷卻之后在進行加水。
            The overload of the excavator engine and the bad heat dissipation will cause the water tank to boil. The first reaction of many repairmen is to add water. However, if this time adding cold water will cause the cylinder head and cylinder to blow up, so the engine should be stopped at this time, and water will be added after its natural cooling.
            二、從不換機油
            Two. Never change the oil
            挖掘機機油在挖掘機當中的作用尤為巨大,很多修理工對此都很重視。他們完全按照標準要求進行添加。但是,很多的修理工卻忘記了對機油質量檢查和蛻變機油的更換。長期的只是添加而不更換機油,就會使得發動機的很多部件在潤滑較差的環境下工作,所造成的磨損遠超正常狀態。而且,柴油機在運轉的過程當中,很多的污物也會進入到機油當中,如果定期不更換機油,很容易引發燒瓦、抱軸等意外事故。
            The oil of excavator is especially important in the excavator. Many repairmen pay much attention to it. They are added completely according to the standard requirements. But many repairmen forgot about the oil quality check and the replacement of the oil. For a long time, only adding but not changing the oil will cause many parts of the engine to work in a poor lubrication environment, resulting in much more wear and tear than normal. Moreover, in the process of diesel engine operation, a lot of dirt will also enter the oil. If the oil is not replaced regularly, it is easy to cause accidents such as burning and holding shaft.
            三、黃油胡亂涂抹
            Three. Daub with butter
            挖掘機黃油其主要地作用是潤滑與密封。所以,有時修理工在維修過程當中,就會在其汽缸墊上涂抹上黃油,認為這樣子就可以增加其柴油發動機的密封性能??墒?,這種做法確實是大錯特錯的。因為,如果在汽缸墊上涂抹了黃油,當汽缸螺栓擰緊時,必然會有一部分黃油流入到氣缸當中。剩下的在外部的黃油在受到高溫影響之后還會造成缸墊、缸蓋與機體平面之間發生一定的縫隙,這樣反倒是降低了缸墊原本的密封性。
            The main function of the excavator butter is to lubricate and seal. Therefore, sometimes the repairman will apply butter on its cylinder pad during the maintenance process, which will increase the sealing performance of its diesel engine. But this is really a mistake. Because if butter is applied to the cylinder gasket, some of the butter will flow into the cylinder when the cylinder bolts are tightened. The remaining outside butter will cause a certain gap between the cylinder pad, the cylinder head and the plane of the body after being affected by the high temperature. In this way, the original seal of the cylinder pad is reduced.
            四、缸套和活塞產品不進行組合即安裝

            Four, cylinder liner and piston products are not assembled or installed.
            很多修理工在維修的時候,認為新品都應該是規范件。所以,在面對新的缸套和活塞產品的時候往往是不看具體尺寸。這樣就會造成很多時候缸套和活塞產品不配套的情況,當大尺寸的氣缸配上小尺寸的活塞,就會使二者間隙過大,壓縮無力。
            Many repairmen believe that new products should be standardized when repairing. Therefore, in the face of new cylinder liner and piston products, often do not look at the specific size. This will cause many times when the cylinder and piston products are not matched. When the maximum size cylinder is fitted with the smallest size piston, the gap between the two is too large to compress.
            五、砂布打磨軸瓦
            Five. Abrasive cloth grinding axle bush
            刮瓦是挖掘機維修當中技術含量相對較高的一項工作,很多的修理工因為自身的技術不過關,就會在進行刮瓦的過程當中直接用砂布進行打磨。但是,在采用砂布進行打磨的過程當中砂布上的沙粒極其容易嵌入到合金當中,加速柴油機軸頸的磨損。
            Scraping is a relatively high technical content in the maintenance of the excavator. Many repairmen will wear it directly in the process of scraping because of their own technology. However, when the abrasive cloth is used for grinding, the sand grains on the sand cloth are very easy to be embedded into the alloy so as to accelerate the wear of the diesel engine journal.
            六、螺栓拼命擰緊
            Six. Tighten the bolt
            在挖掘機維修的過程當中,其實并不是螺栓擰的越緊越的。這主要是因為很多部位針對于螺栓的轉矩都是有要求的。但是,很多的修理工并不這么認為,他們會盡可能的將其擰到緊,這就容易造成螺栓擰斷或者是螺紋滑扣。
            In the process of excavator maintenance, it is not the tighter bolt safety. This is mainly because many parts are required for the torque of bolts. However, many repairmen do not think so. They will tighten them as tightly as possible, which will easily cause bolts to break or thread slips.
            七、輪胎氣壓太高
            Seven. The tire pressure is too high
            如果是輪式挖掘機,在給輪胎進行充氣的過程當中,很多的修理工并不注意輪胎氣壓的問題。這就容易造成夏季工程車輛爆胎的狀況發生。
            If a wheel excavator is used to inflate the tire, many repairmen do not pay much attention to the problem of tire pressure. This will easily lead to the occurrence of tire blowout in summer.
            八、采用明火加溫活塞
            Eight. Heat piston with open fire
            在安裝活塞銷的過程當中,應該先讓活塞受熱膨脹。很多的維修人員為了貪圖方便,直接將其放在明火上進行加熱。但是,因為活塞各部位的薄厚是不均勻的,放在明火上加熱就會造成其受熱不均,后容易引發變形。所以,正確的加熱方式,是應該將活塞放入到熱油當中進行加熱。
            In the process of installing piston pin, the piston should be expanded by heat. Many maintenance personnel directly put them on the open flame for heating purposes. However, because the thickness of each part of the piston is uneven, heating on the open flame will cause uneven heat and finally cause deformation. Therefore, the correct way of heating is to put the piston into the hot oil for heating.
            九、氣缸間測量不準
            Nine. Inaccuracy in cylinder measurement
            測量氣缸間隙,應該在活塞裙部垂直于活塞銷孔的方向測量。但是,很多的修理工在測量的時候,就會因為一時不注意在其它方向進行測量。但是,因為其裙部斷面為橢圓形,所以,氣缸間隙并不相等。
            Measuring cylinder clearance should be measured in the direction of piston skirt perpendicular to piston pin hole. However, many repairmen do not pay attention to other directions when they are measuring. However, because the skirt section is elliptical, the cylinder clearance is not equal.
