During the summer construction, the excavator is hovering at the edge of high intensity. At this time, the driver is most afraid of encountering an abnormal phenomenon of the excavator, because once the fault occurs, it basically indicates the shutdown for repair. Many pilots are distressed by the engine speed loss!
1. Engine failure causes speed loss. The engine load is too large, and the excavator engine itself has insufficient output power, the output power is lower than the rated power, and the speed is too low, which is also caused by a problem with the main pump.
2. Poor fuel quality or high fuel water content will lead to insufficient engine power and speed loss.
3. Hydraulic system failure. The hydraulic system of the excavator has a fault, which makes the hydraulic pump unable to change the displacement normally, causing the system pressure to be too high, and the failure of holding the excavator may occur at the same time when the speed drops.
4. The clearance of the solenoid valve is too large and the oil supply is insufficient, resulting in the excavator engine stalling.
After the above introduction, I believe we all know something about it, so we should pay more attention to the inspection during the operation. The performance of the excavator cannot be separated from careful maintenance. Again, I remind you that the excavator needs three repairs and seven maintenance, which is really not just a talk. Only with careful daily use and careful maintenance can the excavator operate smoothly and unimpeded!
