  看到这个标题,我想江苏快三开奖结果会有疑问。扩展臂在整个项目中变乱得很快,这不是一件功德吗?小编为什么说这是一个标题呢?终究上,这里提到的速率是与你们挖掘机的设定速率相相比的。一些挖掘机曾经被修正为陈设挖掘机的伸缩臂,这与配置自身的速率差异,招致伸缩臂无法控制。那么怎样料理这个标题呢?下面的内容盼望能资助你回答这个标题!
  Seeing this problem, I think we will have questions. Isn't it a good thing that the extension arm works very fast in the whole project? Why did Xiaobian say it was a problem? In fact, the speed mentioned here is compared with the set speed of your excavator. Some excavators have been modified to install the telescopic boom of the excavator, which is different from the speed of the equipment itself, causing the telescopic boom to be out of control. So how to solve this problem? The following content hopes to help you answer this question!
  1. 缘故缘故原因:
  1. Reason:
  挖掘机配有加长臂变乱装置,移动臂长,斗杆长,变乱范围大,容易发生安全变乱。当挖掘机的变乱速率设定为正常变乱速率时,移动臂和斗杆线的速率太快,应用职员无法控制。因此,有必要料理加长臂变乱装置移动过快的标题。
  The excavator is equipped with the working device of the lengthening arm, the moving arm is long, the stick is long, the working range is large, and the safety accident is easy to occur. When the working speed of the excavator is set to the normal working speed, the speed of the moving arm and the stick line is too fast for the operator to control. Therefore, it is necessary to solve the problem that the working device of the long arm moves too fast.
  2. 革新方案的选择:
  2. Selection of improvement plan:
  挖掘机变乱装置的主控制阀由先导压力油控制。先导压力油进入主控制阀阀芯端,推进阀芯左右移动,翻开主控制阀回路。它可以颠末减小主控制阀的尺寸来革新。
  The main control valve of the excavator working device is controlled by pilot pressure oil. The pilot pressure oil enters the valve core end of the main control valve, pushes the valve core to move left and right, and opens the main control valve circuit. It can be improved by reducing the size of the main control valve.
  依据主控制阀阀芯行程和流量面积曲线可以看出,主控制阀阀芯开启进程冉冉增大,阀芯行程越大,主控制阀的流量面积越大。当阀芯移动到冲程的着末时,启齿抵达,颠末主控制阀的流量抵达。
  According to the stroke and flow area curve of the main control valve core, it can be seen that the opening process of the main control valve core increases gradually, and the larger the valve core stroke is, the larger the flow area of the main control valve is. When the spool moves to the end of the stroke, the opening reaches the maximum and the flow through the main control valve reaches the maximum.
  从而,主控制阀阀芯极限,可以淘汰阀芯行程。当主滑阀控制左、右端移动,控制的紧张控制滑阀不克不及抵达完备的中风,主控阀阀门开度不克不及抵达,可以淘汰活动地域,飞扬液压缸的流量,从而淘汰变乱配置的速率。
  Thus, the valve core limit of the main control valve can reduce the valve core stroke. When the main slide valve controls the movement of the left and right ends, the main control slide valve cannot achieve complete stroke, and the valve opening of the main control valve cannot reach the maximum, which can reduce the flow area, reduce the flow of the hydraulic cylinder, and thus reduce the speed of the working equipment.

  3.完成和验证:
  3. Implementation and verification:
  依据以上阐发,颠末对主控制阀的丈量,确定阀芯的全行程为10mm。主控制阀阀芯行程限位讨论陈设后,变乱装置转速明白下降。
  According to the above analysis, through the measurement of the main control valve, the full stroke of the valve core is determined to be 10 mm. After the main control valve element travel limit joint is installed, the rotating speed of the working device decreases obviously.
  以动劈落差为例,举行了阀芯行程限位讨论陈设后的运用性谐和和性实行。发现当阀芯位移限定关键关键陈设了2.5毫米的观光限定,动臂下降的目的和整个呆板的可应用性谐和和抵达挖掘机动臂的下行速率的范例变乱配置,可以餍足挖掘机的需求。
  Taking the dynamic split drop as an example, the operability and coordination tests of the valve core travel limit joint after installation are carried out. It is found that when a travel limit of 2.5mm is installed on the valve core displacement limit joint, the index of boom lowering and the operability of the whole machine, as well as the standard working equipment that can reach the downward speed of the boom of the excavator, can meet the needs of the excavator.
  运用以上要领对挖掘机的伸缩臂举行革新,可以有效地料理变乱装置速率过快的标题,你相识了吗?
  Using the above method to improve the telescopic arm of excavator can effectively solve the problem that the working device is too fast. Do you understand?
