  挖掘机液压锤陈设准确
  Correct installation of hydraulic hammer of excavator
  由于工厂大局部挖掘机没有液压锤的管路附件,以是只提供备用阀门。因此,这些挖掘机在陈设液压锤时,应自行装备管道及附件。图2为紧张部件管道衔接表现图。高回油压力会飞扬液压锤的打击力。为了使液压锤的背压降到最低,庞大回油管路可以颠末滤油器直接回油箱(不再颠末备用阀)。为了方便互换铲斗和开挖,应在接近液压锤的管线上陈设抑制阀。陈设管道时,必需防范污水侵入体系。钢管和讨论应颠末污染地域,软管不得扭接。
  Since most excavators in the factory do not have pipeline accessories for hydraulic hammers, only spare valves are provided. Therefore, when installing hydraulic hammer, these excavators should equip themselves with pipes and accessories. Fig. 2 is the schematic diagram of the main component pipeline connection. High oil return pressure will reduce the impact force of hydraulic hammer. In order to minimize the back pressure of the hydraulic hammer, the ordinary return pipeline can be directly returned to the tank through the oil filter (no longer through the standby valve). In order to replace bucket and excavate conveniently, cut-off valves should be installed on the pipeline near the hydraulic hammer. When installing pipes, sewage must be prevented from intruding into the system. Pipe and joint shall pass through the purified area and hose shall not be twisted.
  要是备用阀没有配置控制油管。在中控体系供油管道中(安全锁紧阀后)添加三个滑轮可提取出压力油,备用阀由电磁阀控制。电磁阀应易于应用开关控制。
  If the standby valve is not equipped with control tubing. Pressure oil can be extracted by adding three pulleys in the oil supply pipeline of the central control system (after the safety locking valve), and the standby valve is controlled by the solenoid valve. Solenoid valves should be easy to operate and switch control.
  挖掘机液压锤的运用
  Use of Hydraulic Hammer of Excavator
  准确的应用可以提高液压锤的变乱遵从,延伸挖掘机液压锤的运用寿命。造作业时,要格外过细以下几点。
  Correct operation can improve the working efficiency of hydraulic hammer and prolong the service life of hydraulic hammer of excavator. When doing homework, we should pay special attention to the following points.
  1. 液压锤钻杆不停垂直于分裂物体的外貌。用钻杆把分裂的物体压紧。分裂后立刻抑制液压锤的变乱,防范空锤跳动。
  1. The hydraulic hammer drill pipe is always perpendicular to the surface of the crushed object. Tighten the broken object with a drill pipe. Stop the work of hydraulic hammer immediately after crushing to prevent the air hammer from jumping.
  2. 当打碎十分壮实的物体时,应先从敲打的边沿末端,不要在同一点延续敲打一分钟,以防范钻杆熄灭或液压油过热。
  2. When breaking a very hard object, it should start at the edge of the knock and not continue to knock for a minute at the same point to prevent the drill pipe from burning or the hydraulic oil from overheating.
  3.挖掘机转弯时,不要让钻杆遇到其他物体。
  3. When the excavator turns, don't let the drill pipe touch other objects.
  4. 在水作业中,只需钻杆才气浸入水中。要是需要将全部液压锤浸入水中,应向制造商订购格外的水下液压锤。

  4. In water operation, only drill pipe can be immersed in water. If all hydraulic hammers need to be immersed in water, special underwater hydraulic hammers should be ordered from manufacturers.
  挖掘机液压锤的维护
  Maintenance of Hydraulic Hammer of Excavator
  由于液压锤的事境况态很差,准确的维修可以淘汰呆板拦阻的发生,延伸呆板的运用寿命。除了挖掘机的一样伟大维护外,还应过细以下几点。
  Due to the poor working condition of hydraulic hammer, correct maintenance can reduce the occurrence of machine failure and prolong the service life of the machine. In addition to the daily maintenance of excavators, the following points should be noted.
  1. 外表查抄:查抄钻杆与衬套之间的间隙,查抄钻杆与衬套之间可否有液压油泄漏。如有漏油,说明高压油封渗漏已粉碎,应由专业职员互换。查抄螺栓可否松动,维修衔接处的销轴可否磨损。
  1. Appearance inspection: check the gap between drill pipe and bushing, check whether there is hydraulic oil leakage between drill pipe and bushing. If there is oil leakage, it indicates that the leakage of low pressure oil seal has been damaged and should be replaced by professionals. Check whether the bolt is loose and whether the pin at the repair joint is worn out.
  2. 每天至少给变乱装置的润滑点涂两次油。
  2. Oil the lubrication point of the working device at least twice a day.
  3.用液压锤改换滤芯和液压油时,液压油的蜕变和污染比庞大斗式应用快得多。正常环境下,应在正常互换周期的一半互换液压体系中的滤芯和液压油。
  3. When using hydraulic hammer instead of filter element and hydraulic oil, the deterioration and pollution of hydraulic oil is much faster than that of conventional bucket operation. Normally, the filter element and hydraulic oil in the hydraulic system should be replaced at half of the normal replacement cycle.
  备用阀门没有陈设控制油管。在中控体系供油管道中(安全锁紧阀后)添加三个滑轮可提取出压力油,备用阀由电磁阀控制。电磁阀应易于应用开关控制。
  The standby valve is not fitted with the control tubing. Pressure oil can be extracted by adding three pulleys in the oil supply pipeline of the central control system (after the safety locking valve), and the standby valve is controlled by the solenoid valve. Solenoid valves should be easy to operate and switch control.
