Komatsu PC200-6 can be said to be a real good machine. This car has a history of more than 20 years. The production time in Japan is about 1995. Of course, there are also domestic. Komatsu PC200-6 is one of the classic models of mass production and sales in the domestic market. This article describes the Komatsu PC20, which is maintained in Qingyang, Gansu. The 0-6 revolving sound is becoming more and more malfunctioning.
In the process of working, the excavator is unavoidable to make a series of noise, and it is also a common meal, so when the excavator is small or is not easy to distinguish the noise directly, many machine hands are ignored directly.
But recently, there was a call for help from a master in Qingyang, Gansu, to the master of the MALEIt repair factory. It was worth a lot of people to give it a warning. At first, the machine's Excavator turned a slight noise, but it did not give him enough attention, resulting in a growing louder and more trouble.
The following is a detailed account of the owner's trouble shooting, trouble shooting and final handling. I hope you can learn from them.
Failure phenomenon
During the work of the Komatsu PC200-6 excavator, there is a serious sound noise when the rotary earth is turned around and there is a sound noise in the empty and the other rotating and rotating brakes. In addition to this, all the work of the excavator is normal.
fault analysis
When the fault is rotating, the abnormal sound will occur, and the rotary motor rotates and the brake is normal. The problem is directly locked into the rotary reducer and the rotary support, and the rotary reducer can be disassembled and checked.
Fault check
The motor assembly is removed, the motor is checked separately and the sun wheel and bracket are normal. It is normal to remove the planet rack and bracket. The eccentricity is found when checking the output axis, and when the rotation is rotated, it is dismantled and found that the bearing has been rounded and the shell is also worn seriously.
Troubleshooting
Because the bearing damage caused the reducer shell to wear seriously, so the replacement of the reducer assembly was normal. In the whole inspection and treatment process, the excavator closed for nearly two days, the owner not only took the replacement of the cost of the replacement parts, the whole project was also delayed.
Because this model is the Komatsu PC200-6, the rotary reducer bearing is designed for butter lubrication, but the user has not paid attention to maintenance in a long time, so it will be damaged by dry wear and wear. Under normal conditions, the bearing must be added in butter for maintenance for about 500 hours.
Summary of the increasing maintenance of Komatsu PC200-6 revolving sound
Through the introduction of this article, many machine friends can understand that the fault can be completely circumvented. As long as the user can pay enough attention to the maintenance problem when using the excavator daily, it will not cause such a big loss in the later period.
At the end of the article, again remind you that the excavator is not unconquering, whether it is domestic machine or import machine, so the daily maintenance must be careful and careful, can not ignore any one of the details!
