相关问答

问:比特棋牌CASE挖掘机大臂图纸尺寸 提供一下

答:你可以去铁甲论坛看一看那里有很多专业人士。

问:挖掘机大臂断裂怎么修复? 要细致的过程+图片

答:  一、焊前必须将焊接处清理干净。

  二、焊接前要进行一定的预热。

  三、焊接时必须选用合适的焊接材料。

  四、焊接时必须保证焊透

  焊条型号很重要。如果想弄懂啥材质那就得取些铁沫化验,一验就出来了,然后根据成分配焊条就行了。J507焊条足够用了,抗拉强度50公斤级的,它不过就是一种结构钢。如果507你以前用过又能保证焊透而且还裂,建议你换J607的。应该够用了。

比特棋牌  焊接前必须清理,(就是把原来的开裂焊肉拿掉,用交相磨光机磨或有条件就用碳弧气刨,但刨后必须打磨干净氧化铁)有可能的话还需要在焊接位置预热100度。而后再用直径3.2J507焊条焊,焊一会就停下来,用锤子敲击焊缝和焊缝边缘,待完全焊完后一直用锤子敲击,直到焊缝基本冷却。目的是释放焊接应力,因为焊后不可能做热处理。焊接时必须保证焊透,如果焊缝位置间隙大可以在里边加背板。

问:挖掘机挖地面大小臂怎么操作挖过去是平的?

答:  挖掘的深度,可以目测,就是这个动作,可以用尺子量出来,到那里是多深,时间长了,只看深度就知道有多少了。 1M以内的找平,可以分层的。最后剩下20CM左右,再挎平,记住,铲子在收的时候,铲斗底面和地面要平行。 土堆有高有低的找平。包括这几个动作,往前推,往后沟土,拉着转向左右上下带着土过去。找的平不平呢,第一,就是自己的微操作,手柄动多大的位置,车子动多少,铲斗比自己的胳膊更灵活,那就差不多了。就是手和脑的配合,要自己去领会。第二,就是看出哪里高哪里矮,土该往哪里放。一定要整体性的考虑。 你下来看看就知道不平了,看看哪里不平。然后你再回到车上慢慢的观察就会发现了,不平的地方和平的地方时不一样的。把它找平,完了下来再看,一般就可以了。主要就是观察了,多下来看看。
