  How to solve the problem that the working speed of the long arm of excavator is too fast?
  如何解决挖掘机长臂工作速度过快的问题?
  Isn't it a good thing that the extended long arm excavator works very fast in the whole project? Why does Xiaobian say it's 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, and the telescopic boom cannot be controlled. So how to solve this problem?
  加金沙手机娱乐网址长臂挖掘机在整个工程中工作得很快,不是一件好事吗?小编为什么说有问题?实际上,这里提到的速度是与您的挖掘机的设定速度相比较的。部分挖掘机进行了改装,安装了与设备本身速度不同的挖掘机伸缩臂,伸缩臂无法控制。那么如何解决这个问题呢?
  1. reasons:
  一。原因:
  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.
  挖掘机配有加长臂工作装置,活动臂长,斗杆长,工作范围大,容易发生安全事故。当挖掘机的工作速度设置为正常工作速度时,动臂和斗杆管路的速度太快,操作员无法控制。因此,有必要解决长臂工作装置动作过快的问题。
  2. Selection of improvement plan:
  2。改进方案的选择:
  The main control valve of the excavator working device is controlled by pilot pressure oil. The valve element end of the pilot pressure oil main control valve pushes the valve element 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.
  挖掘机工作装置的主控制阀由先导压力油控制。先导压力油主控制阀的阀芯端推动阀芯左右移动,打开主控制阀回路。可以通过减小主控制阀的尺寸来改进。
  According to the stroke and flow area curve of the main control valve core, it can be seen that the opening of the main control valve core increases gradually, and the larger the stroke of the valve core is, the larger the flow area of the main control valve is. When the spool moves to the end of the stroke, the opening is reached and the flow through the main control valve is reached.
  从主控阀阀芯的行程和流量面积曲线可以看出,主控阀阀芯的开度逐渐增大,且阀芯行程越大,主控阀的流量面积越大。当滑阀移动到冲程的末端时,达到开口并达到流经主控制阀的流量。
  Thus, the limit of the main control valve core can make the valve core travel. When the main slide valve controls the movement of the left and right ends, the main control slide valve can not reach the complete stroke, the opening of the main control valve can not reach, the flow area can be flowing, the flow of the hydraulic cylinder can be reduced, so as to work the speed of the equipment.
  因此,主控制阀芯的极限可以使阀芯行程。当主滑阀控制左右两端的运动时,主控制滑阀不能达到全行程,主控制阀的开度不能达到,流通面积可以流动,液压缸的流量可以减小,从而工作设备的速度。
  3. Implementation and verification:
  3.实施与验证:
  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 and the standard working equipment that can reach the downward speed of the boom of the excavator can meet the demand of the excavator.
  以动态劈裂落差为例,对安装后的阀芯行程限位接头进行了可操作性和配合性试验。研究发现,在阀芯位移限位接头上安装2.5mm行程限位装置时,能够达到挖掘机臂架下降速度的臂架下降指标和整机的可操作性,以及标准的工作设备能够满足挖掘机臂架下降速度的要求。
