Method for automatic flameout after excavation

Recently, a failure phenomenon of an automatic shutdown of the excavator after overhaul was dealt with. Details of the failure: A 320D excavator was tested after an overhaul. The failure of the automatic shutdown of the excavator occurred after about an hour of operation. Start it again, it won't start.

Based on experience and phenomenon, the common processing methods of automatic flameout of excavator are introduced.

1. The excavator is an automatic flameout phenomenon of the testing machine after overhaul. It cannot be started when the machine is restarted. Excavator maintenance is the use of a bucket to dig materials above or below the bearing surface and load them into a transport vehicle or earthmoving machinery to a dump. Common excavator structures for repairing excavators include power units, work units, slewing mechanisms, operating mechanisms, transmission mechanisms, walking mechanisms, and auxiliary facilities. After failure, the main machine of the excavator can first check the oil circuit and fluid of the following excavators. If there is a fault, the 320D trencher will automatically stop after the main maintenance.

2. If there is no problem with the digging machine oil or oil, then the teacher needs to continue the digging machine inspection to see if the machine cannot start and stop for a while before digging? If it can be started after stopping for a period of time, and then continue to check and start digging, it will automatically shut down after the overhaul of the digger again. It seems that it does not?

three. If the excavator automatically shuts down again, the reason for the automatic shutdown of the 320d excavator after overhaul may be that the plunger clearance of the injection pump of the excavator is too small

As the temperature of the excavator rises, the plunger will expand and conflict with the oil valve. The gap is too small, it will not move back and forth normally, affecting the oil supply of the excavator, resulting in the phenomenon of automatic flameout after the overhaul of the excavator. After a period of shutdown, the temperature of the excavator drops, and when the temperature rises, the automatic flameout failure occurs after the overhaul of the excavator Therefore, the gap between the plunger and the oil outlet valve needs to be adjusted to solve the automatic flameout failure after the overhaul of the excavator.

In the actual case of excavator maintenance, many common failures are caused by the excavator master not paying attention to the component clearance. If you do not pay attention to check whether the clearance between the components is too large or too small, it is likely to cause early bearing wear and digging. Faults such as machine burning oil, difficulty in starting the excavator, oil leakage from the excavator, and air leakage from the excavator occur, so the maintenance master must pay attention to the gap between the parts of the excavator to prevent the failure of the excavator.
