With the development of construction machinery, excavator bucket has played a great role in our construction machinery, but in the process of using, many people don't know how to retract the bucket. Here is a brief introduction:

挖掘机收铲斗步骤：

Steps for excavator to retract bucket:

1、怀疑是阀芯(隶属阀体)卡死了,到了现场发现铲斗在打开位置收不回,而且还有点掉臂现象。

1. It is suspected that the valve element (attached to the valve body) is stuck. When arriving at the site, it is found that the bucket can not be retracted in the open position, and there is a bit of arm dropping phenomenon.

2、试车,当做回收动作时铲斗还会打开点,打开阀盖,抽出阀芯(隶属阀体)发现有小拇指那么大的铁块,看到后故障点是油缸端造成。修理挖掘机公司拥有的分配阀液压系统***检测设备,专修挖掘机油温高、动作慢、无力、憋机、难启动、大小臂发卡动作不理想、水温高发动机等疑难故障。

2. During the test run, when the bucket is used as the recovery action, it will open the point, open the valve cover, pull out the valve core (attached to the valve body), and it is found that there is an iron block as big as a small thumb, and the fault point is caused by the cylinder end. Repair excavator company has advanced accurate detection equipment for distribution valve hydraulic system, and specializes in repair of difficult faults such as high oil temperature, slow action, powerlessness, holding machine, difficult to start, unsatisfactory action of large and small arms, high water temperature engine, etc.

3、拆开铲斗油缸,发现内六角锁紧螺母不见,到处是螺母的压痕,判断是人为装配时没有紧固小螺钉,导致螺钉松脱后把活塞和缸桶磨坏,铁块在分配阀上面卡住阀芯(隶属阀体)造成没有动作,出现挖掘机铲斗突然收不回,还有点掉臂现象发生。

3. Dismantle the bucket oil cylinder, and find that the hexagon lock nut is missing, and there are indentations on the nut everywhere. It is judged that the small screw is not tightened during artificial assembly, which causes the piston and cylinder barrel to be worn out after the screw is loosened, and the valve core (attached to the valve body) is stuck on the distribution valve by the iron block, resulting in no action. The bucket of the excavator suddenly fails to retract, and there is a bit of arm falling.

在我们收铲斗的过程中，装配时螺钉未紧固,小小一个东西造成的危害真的很大。修理挖掘机业的挖掘机维修厂，修理挖掘机冒黑烟,水温高,难启动,动作慢,憋车故障，技术团队,修理各种挖掘机疑难故障。

In the process of retracting the bucket, the screws are not tightened when assembling, and the damage caused by a small thing is really great. Repair the excavator maintenance plant in the excavator industry, repair the black smoke of the excavator, high water temperature, difficult to start, slow motion, car holding fault, professional technical team, repair various brand excavator difficult fault.
