Facing the stagnant situation in the current engineering machinery industry, with the increase of fuel prices, the profit space of the excavators is getting smaller and smaller. Engineering machinery is so large that the oil consumption is so huge that it can even be said that oil prices have seriously affected the income of the machine hands. Under the premise of the life of the equipment, oil saving is a hot topic in the construction machinery industry.
I know the bitterness of the engineers in the engineering machinery industry, and collect some 5 small techniques about the operation of the excavator's oil saving operation.
1. high position mining
In the operation, first select the higher part of the mining position, and then dig out the lower part of the position, compared with the direct low level mining, can shorten the period of about 12% of the period, and can increase the fuel consumption by about 8%.
2. bucket bar mining range
When the bucket oil cylinder and the connecting rod, the head rod oil cylinder and the head rod are all 90 degrees, the cylinder drives the excavator to have the greatest strength. The excavating of the natural ground, the bucket or the ground angle of the excavator is kept about 30 degrees, the bucket rod is close to the vertical, the bucket force is maximum and can carry the load more. The minimum excavating force of the bucket rod is the minimum. The difficulty of digging is increasing. Therefore, when excavating at the beginning, do not extend the bucket to the maximum range of action. The effect is best from about 80%.
3. avoid engine idle
When the engine rotates, the hydraulic pump will also have oil in the cycle and consume fuel, assuming that there are 1 hours in the 1 days and 10 hours is in the empty, then, if can avoid empty turn, can save about 230 liters of fuel every year, so in the process of daily loading or operation, a long time of stopping the machine, try not to open the idle "wait".
4. avoid heavy load pressure drop
If the excavated sand or stone load is overloaded, the excavator will fall into the pressure drop shape. Assuming that there are 6 minutes in the 1 days and 10 hours for the pressure drop form, if the pressure drop can be avoided, it can throttle about 840 liters of diesel every year.
5. reduce circling angle
Reducing the angle of hovering in the loading of dump trucks can shorten the operation cycle and increase the amount of work in unit work, thus improving burnup efficiency.
