2. In the speed state, open the side fixing of the hydraulic main pump side and find the idle speed of the main hydraulic pump connecting the main pump and the control valve.

3. Hold the hydraulic pipe lightly in one hand, and feel the flow state of the hydraulic oil with the other hand. Normally, the flow of hydraulic oil tends to be stable and continuous pressure output, there will be no noise, and you will feel the hydraulic oil when you touch it. A pulsed output with some jitter.

4. Comparing the flow state of the hydraulic oil in the main hydraulic pipeline of the front and rear pumps, for example, the pipeline of the front pump connected to the excavator accessories vibrates greatly and the flow of the hydraulic oil is not stable to the touch. It can be judged that the main pump plunger shoe has fallen off.

5. Downtime maintenance

Because the hydraulic system is required to be very clean, the equipment needs to be moved slowly to a flat place and away from dust during maintenance. Most of the debris should be found when the main pump of the excavator parts is disassembled. Once it enters the hydraulic system, it will be relatively trouble.

(2) The excavator driver should have skilled operation techniques and try to use compound operations to shorten the operation cycle time of the excavator.


(3) Reasonable layout of the excavator worksite: During the construction, the driving route of the dump truck should be drawn up in advance, and unnecessary uphills should be removed. For each road of the excavator, there must be an empty return road to avoid mutual interference when the dump truck enters and exits. The running lanes should be kept in good condition to facilitate the operation of the dump truck.


(4) Correctly carry out the construction organization design. The number and carrying capacity of dump trucks matched with the excavator should meet the requirements of the production capacity of the excavator, and the capacity of the dump truck should be an integer multiple of the bucket capacity of the excavator. Excavator parts manufacturers remind you to use the double-loading method as much as possible at the same time so that the excavator is filled with one, and then the next one is loaded. On the arc, the bucket can be filled with one car in the forward direction, and the other car can be filled in the reverse direction, thereby improving the loading efficiency.
