挖掘机大小臂的控制视频

SANJIEBEIDEWAJUEJI, SHOUBINGRUHEKONGZHI? KAIYITIANBOZIDOUSHENBUZHILE

相关问答

问:怎么样才能控制好挖掘机的大小臂

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。

问:比特棋牌小松pc56挖掘机行走正常,大小臂不动作,是什么故障引起的?

答:比特棋牌你检查下大小臂的控制系统液压油是否有输出,如果没有就是控制部分问题或者没有液压油了

问:怎么将挖掘机上的大小臂油缸拆下来

答:是油缸内漏~~其实拆油缸很简单的啊,先把油缸和小臂连接处的销子拿掉~然后把油缸上的内六角螺丝下掉~最后把油缸慢慢放出来 是上驾驶室用操作杆操作油缸放出来哦 ~这样油缸就可以拿下来了,下中臂油缸的话在油缸上固定一根绳子找个铲车或是挖机吊着你再慢慢放出来~ 如果你不会弄的话就找专业的人来修
希望采纳

问:挖掘机大小臂不同时工作是什么原因

答:比特棋牌能具体点么?在什么档位?大臂提升+小臂收回不能同时动,还是大臂下降和小臂伸出不能同时动作?还是都不能?

问:挖掘机大小臂自动下降是怎么回事

答:可能是液压不足或是控制液压的机械部份需要调整,太松了。液压是机械行业、机电行业的一个名词。液压可以用动力传动方式,成为液压传动。液压也可用作控制方式,称为液压控制。液压传动是以液体作为工作介质,利用液体的压力能来传递动力。液压控制是以有压力液体作为控制信号传递方式的控制。用液压技术构成的控制系统称为液压控制系统。一个完整的液压系统由五个部分组成,即能源装置、执行装置、控制调节装置、辅助装置、液体介质。液压由于其传递动力大,易于传递及配置等特点,在工业、民用行业应用广泛。液压系统的执行元件(液压缸和液压马达)的作用是将液体的压力能转换为机械能,从而获得需要的直线往复运动或回转运动。液压系统的能源装置(液压泵)的作用是将原动机的机械能转换成液体的压力能。

支撑用的液压部分有问题!
比特棋牌可能是液压不足或是控制液压的机械部份需要调整,太松了。

主要可能是油泵的问题,
比特棋牌请找专业人员,来校对一下油泵。
