挖掘机油缸总坏的原因都在这里了!

工作装置未完全回收就行走
Walking without complete recovery of working device
工作装置没完全收回的情况下行走,挖斗很容易撞到岩石,油缸活塞杆会产生较大负荷,导致油缸内部破损以及销轴周边开裂。
When the working device is not fully retracted, the bucket is easy to hit the rock, and the piston rod of the oil cylinder will produce a large load, resulting in damage inside the oil cylinder and cracking around the pin shaft.
油缸杆伸缩到极限进行挖掘
The cylinder rod extends to the limit for excavation
液压油缸伸缩到尽头位置作业,这种情况下工作油缸、机架会产生较大的负荷,斗齿的冲击、各个轴销的冲击,会造成油缸内部破损,还会影响其他的液压部件。
The hydraulic oil cylinder is retracted to the end position for operation. In this case, the working oil cylinder and frame will produce a large load. The impact of bucket teeth and each axle pin will cause damage inside the oil cylinder and affect other hydraulic components.

履带后部浮起做挖掘作业
The rear of the track floats for excavation
利用挖掘机车体后部上浮的力量来进行挖掘作业。当挖斗和岩石分开,车体下落时对挖斗、配重、机架、回转支撑等产生较大的负荷,很容易造成损伤。
Use the floating force at the rear of the excavator body to carry out excavation. When the bucket is separated from the rock and the car body falls, it will produce a large load on the bucket, counterweight, frame and rotary support, which is easy to cause damage.
借助行走力挖掘

液压油混入水后容易乳化变质,乳化液压油进入液压系统会到导致零部件生锈。锈渣长期在液压系统内流动,液压压力会受到影响,大小臂、挖斗动作会因此变得无力。
The hydraulic oil is easy to emulsify and deteriorate after mixing with water. The emulsified hydraulic oil entering the hydraulic system will lead to rust of parts. The rust slag flows in the hydraulic system for a long time, the hydraulic pressure will be affected, and the action of large and small arms and bucket will become weak.
挖机没站稳就开工
The excavator started without standing still
路面不平整的石子路,在挖机未停稳的状态下开始作业,长久下来会造成下车架受力不均,引起下车架受损。更好是在下方垫一些土,使地面平稳,这样再作业。
For the stone road with uneven road surface, when the excavator is not stopped stably, the stress on the lower frame will be uneven and the lower frame will be damaged for a long time. It is best to pad some soil below to make the ground stable before operation.
