No matter what kind of machine, need to be maintained to use for a long time, excavator is no exception, maintenance is very important, can not be ignored. For those who are not familiar with the operation, it is necessary to pay more attention to the matters needing attention of the excavator, to look at the maintenance manual, to understand the basic situation of the extended arm of the excavator, to know how many hours to change the oil, to change the air cleaner, and to walk on the basis of the walking distance. If the air cleaner has a lot of ash, it should be cleaned up in time and the oil should be replaced with a thick one. Chemical engine oil, applicable to the hydraulic system where there is a leakage must be dealt with in a timely manner, oil tank to do a good job of insulation, the lubrication of the place to often beat butter and so on. Learn from the most basic butter.
The use of lubricating oil (butter) can reduce wear on the surface and prevent noise. Dust, sand, water and other impurities should not be mixed into the grease during storage; G2-L1 is recommended for lithium-based grease, which has good wear resistance and is suitable for heavy load conditions; when filling, the old oil should be extruded and wiped clean as far as possible to prevent sand adhesion.
如果长期不打销子和套子要被磨大，慢慢的销子就会断或者套子被磨烂。打黄油要养成习惯，挖机的大毛病就是这些小问题积累而来的。一般活动量最大的地方，磨损会比较大，因此打黄油的频率也会适当高些。特别是挖斗上的6个黄油嘴最重要，因为活动量最大，所以每作业8小时就应该加注一次黄油，另外就是挖掘机标准大小臂连接处3个，大臂上5个，大臂油缸下2个 一天加注一次最好，24小时打一次也没事，主要看干什么活，这个自己掌握。回转转盘一般每作业250小时加注一次，这个不能频繁加注、一次不能加注过多，因为转盘有防尘防水油封 过多 过频繁加注会损坏油封。
If the pin and sleeve are to be worn for a long time, the pins will be broken or the sleeves will be worn away. It is necessary to build a habit of beating butter. The major problem of digging machines is the accumulation of these small problems. In general, where the maximum amount of activity is, wear will be larger, so the frequency of butter will be higher. Especially the six butter nozzles on the bucket are the most important, because the activity is the largest, so every 8 hours should be filled with butter, and the other is the excavator standard arm joints three, five arms, two under the arm cylinder filling a day best, 24 hours a time is also okay, mainly to see what work, this from You have mastered it. Rotary disc generally every 250 hours to fill a time, this can not be frequent filling, one can not add too much, because the rotating disc has dust-proof waterproof oil seal too much frequent filling will damage the oil seal.
In fact, the excavator works normally, the general situation every day to fill butter, especially the bucket shaft, every day check the oil, hydraulic oil, at any time clean up the air filter. In addition, attention should be paid to the operation of long arm excavators.
