日期:2019-10-24   源头:http://www.sefibox.com/
  水陆两用挖掘机在夏季的拦阻率很高,而夏季又恰恰是抢修的季候,以是很多机主敷衍呆板的不动、高温等拦阻都很头疼。今天我想跟大家谈一谈液压挖掘机在租赁施工进程中出现的随手拦阻,比如转动不动等正常方法。以下是先容给您的阐发和处置进程,盼望能给您带来参考。
  The failure rate of amphibious excavator is very high in summer, and summer is just the season of rush repair, so many owners have a headache about the immobility, high temperature and other failures of the machine. Today, I would like to talk about the troublesome faults of hydraulic excavators in the process of leasing construction, such as the normal movement of rotating. The following is an introduction to your analysis and solution process, hoping to give you a reference.

  Failure analysis:
  起首,招致宁夏水陆两用挖掘机在租赁进程中出现不动标题的缘故缘故原因有很多,以是工程师们起首逐一阐发了有数的拦阻缘故缘故原因:
  First of all, there are many reasons for the immobility of the amphibious excavator in Ningxia during the leasing process, so the engineers first analyzed the common failure reasons one by one:
  1. 由于先导手柄旋转阀芯拦阻招致先导油回路无法举行;
  1. The pilot oil circuit cannot be operated due to the failure of the pilot handle rotary valve element;
  2. 旋转电机安全阀阀芯及液压油溢出,无法正常设定旋转压力;
  2. The safety valve core and hydraulic oil of the rotary motor overflowed and the rotary pressure could not be set normally;
  3、液压主控制阀芯旋转发卡,液压油不克不及抵达旋转电机;
  3. The hydraulic main control valve core is rotated and jammed, and the hydraulic oil cannot reach the rotating motor;
  4. 旋转电机外部柱塞或其他部件粉碎,招致旋转电机运转十分;
  4. The internal plunger or other parts of the rotating motor are damaged, resulting in abnormal operation of the rotating motor;

  5. 旋转减速机构的内齿轮或其他部件粉碎,招致旋转减速机构不克不及正常变乱;
  5. The internal gear or other parts of the rotary reducer are damaged, resulting in the failure of the rotary reducer to work normally;
  6、反转展转机构与反转展转支承讨论失效,如齿轮磨损。
  6. The joint between the slewing mechanism and the slewing bearing fails, such as the gear is worn.
  拦阻扫除要领:
  Troubleshooting:
  1、启动呆板并做旋转活动,过细观察旋转活动时平台可左右摆动,摆动时十分声响,呆板感明白停滞征象。可坚强反转展转减速机构外部拦阻或反转展转机构与反转展转支承衔接拦阻。
  1. Start the machine and make rotation movement. Carefully observe that the platform can swing left and right when rotating. When swinging, it makes abnormal sound and the mechanical sense is obviously stagnant. It can be used to judge the internal fault of slewing reduction mechanism or the connection fault of slewing mechanism and slewing bearing.
  2. 拆下衔接反转展转机构与反转展转平台的螺栓环,抬起反转展转机构总成,查抄反转展转机构与反转展转支承的衔接,发现反转展转自动齿轮与反转展转环齿轮正常;
  2. Remove the bolt ring connecting the slewing mechanism and the slewing platform, lift the slewing mechanism assembly, check the connection between the slewing mechanism and the slewing bearing, and find that the slewing driving gear and the slewing ring gear are normal;
  3.拆下并查抄旋转减速箱,发现第一减速中心齿轮磨损告急,第二减速机支持架粉碎;
  3. Dismantle and check the rotary reducer, and find that the first reduction center gear is severely worn and the second reducer support frame is damaged;
  4、互换新的旋转机构总成,扫除拦阻。
  4. Replace the rotating mechanism assembly with a new one and remove the fault.
