Modern construction is inseparable from engineering construction, and excavator is inseparable from engineering construction. Today, we will bring a good method to quickly and effectively deal with the problem that Komatsu excavator is slow and unable to work when it is repaired!
1、 Correct fault cause analysis is a useful guarantee for Komatsu excavator to repair and deal with excavator problems.
1. The manipulator reflects that there is no high speed when the machine travels.
2. On site inspection, the engine is at full throttle and adjusted to high gear. Measure the speed of walking alone and walking on both sides at the same time as the low speed.
3. Enter the monitoring panel to check that the front pump pressure is 224kg / cm2 and the rear pump pressure is 39kg / cm2 when the machine is idling. During overflow, the pressure of the front pump is 224kg / cm2, and the pressure of the rear pump is 353kg / cm2. It is judged that the front pump pressure is abnormal.
4. The voltage of A51 was measured. 1 and 3 were 5V, and 1 and 2 were 4.1V. There were no abnormal values.
Komatsu excavator repair - a wonderful way to deal with slow excavator speed!
5. After inserting a52 into the front pump pressure sensor, the rear pump pressure appears on the monitoring panel as 224kg / cm2.
6. There is no abnormality in other actions of the excavator.
2、 "Suit the remedy to the case" is the final method for Komatsu excavator to repair and deal with the problems of the excavator.
After replacing the front pump pressure sensor, the fault is eliminated.
