攪拌車保養中容易出現哪些誤區?

所屬分類:公司新聞 發布時間:2021-01-20 來源:http://www.whjchh.com 瀏覽量:18

俗話說得好,混凝土攪拌車七分保養三份修。雖然攪拌車體型龐大,但是其內在的零部件是非常脆弱的,只有定期檢查和保養,才能延長愛車的使用壽命。有些司機在攪拌車的日常保養中會出現一些操作不當的情況。
As the saying goes, the concrete mixer is maintained in seven parts and repaired in three parts. Although the mixer is huge, its internal parts are very fragile. Only regular inspection and maintenance can extend the service life of the mixer. Some drivers in the daily maintenance of mixer will appear some improper operation.
一、亂涂黃油
1、 Daub butter
攪拌車打黃油主要是起一個潤滑的作用,一般攪拌車旋轉、嚙合等地方都需要黃油。有些維修工會在汽缸墊上也打上黃油,借此增強發動機的密封性。這種做法是錯誤的。氣缸螺栓擰緊后,一部分黃油不可避免地會流入氣缸,外面殘余的黃油在高溫下還會在缸墊、缸蓋與機體平面之間形成縫隙,反而降低密封性。
The main purpose of beating butter on the mixer is to lubricate it. Generally, butter is needed in the rotation, meshing and other places of the mixer. Some maintenance workers also put butter on the cylinder gasket to enhance the tightness of the engine. This is wrong. After the cylinder bolts are tightened, part of the grease will inevitably flow into the cylinder, and the residual grease will form a gap between the cylinder gasket, cylinder head and the plane of the engine block at high temperature, which will reduce the sealing performance.
二、長時間不換機油
2、 Do not change the oil for a long time
更換機油是許多司機容易忽視的一點。如果長期只是一昧地添加機油,發動機的許多零部件會缺少潤滑,長此以往磨損加劇。柴油機在運轉的過程中也會吸附很多雜質進入機油,如果長期不更換機油,可能導致燒瓦、抱軸等問題。
自動上料攪拌機
Changing engine oil is a point that many drivers tend to ignore. If the engine oil is added blindly for a long time, many parts of the engine will be lack of lubrication, and the wear will increase in the long run. During the operation of diesel engine, a lot of impurities will be absorbed into the engine oil. If the engine oil is not changed for a long time, it may cause problems such as Bush burning and axle holding.
三、明火加溫活塞
3、 Open flame heating piston
有經驗的維修工都知道,在安裝活塞銷之前,要先讓活塞受熱膨脹。一些人為了省事,直接用明火對活塞進行加熱。這種方式會讓活塞受熱不均產生變形,正確做法是講活塞放入熱油中均勻受熱。
Experienced repairmen know that the piston should be heated and expanded before installing the piston pin. In order to save trouble, some people directly use open fire to heat the piston. The correct way is to put the piston into the hot oil and heat it evenly.
四、使用砂布打磨軸瓦
4、 Use emery cloth to grind the bearing bush
刮瓦技術難度較大,缺乏經驗的維修工難以掌握,為此,有人在更換軸瓦時,為了增大軸瓦與曲軸的接觸面積,就用砂布打磨代替刮瓦。這種方法會使砂布上較硬的顆粒嵌入軸瓦合金,柴油機運轉過程中加速軸頸的磨損,縮短曲軸的使用壽命。
It is difficult for inexperienced maintenance workers to master the scraping technology. Therefore, when replacing the bearing bush, in order to increase the contact area between the bearing bush and the crankshaft, someone uses abrasive cloth to grind instead of scraping the bearing bush. This method will make the hard particles on the abrasive cloth embedded in the bearing bush alloy, accelerate the wear of the journal during the operation of the diesel engine, and shorten the service life of the crankshaft.
