Now people's living standards have improved, and all kinds of prices are rising, especially the oil price. Therefore, how to save fuel without affecting the normal work and service life of the excavator's extension arm has become a topic of concern for many people. Here are some suggestions.

　　1. 防止发动机空转

　　1. Prevent the engine from idling

　　即使泵空转，仍会有油在泵内循环并消耗燃料。如果每天10个小时的工作时间中有一个小时是空闲的，那么，如果可以避免空闲，每个月大约可以节省20个声音，每年大约可以节省230升燃料。因此，在日常装载或挖掘过程中，中途可长时间停车，尽量不要打开挖掘机空转速度“等待”，要工作和休息，更省油，这是挖掘机省油的秘诀之一

　　Even if the pump idles, there will still be oil circulating in the pump and consuming fuel. If one hour of the 10 hours of work per day is idle, then, if idle can be avoided, about 20 sounds can be saved each month, and about 230 liters of fuel can be saved each year. Therefore, in the process of daily loading or excavation, you can stop for a long time midway. Try not to open the idle speed of the excavator and "wait". You should work and rest to save more fuel. This is one of the secrets of the excavator to save fuel

　　2. 防止过载压力损失

　　2. Prevent overload pressure loss

　　当挖出的砂石超载时，即使拉动操作机械的操纵杆也不动，处于失压状态。如果1天10小时的运行时间有6分钟为失压状态，那么，如果能防止失压，每月可节省约70升，每年可节省约840升柴油，这一项费用接近5000元的费用。

　　When the excavated sand and stone are overloaded, even if the control lever of the operating machine is pulled, it will not move and will be in the state of pressure loss. If the running time of 10 hours in a day is 6 minutes in the state of loss of pressure, if the loss of pressure can be prevented, about 70 liters of diesel can be saved every month, and about 840 liters of diesel can be saved every year. This cost is close to 5000 yuan.

　　我们都知道铲子不能的问题，可以分成两部分来，否则既机器，又耗油，是不值得的损失。

　　We all know that the problem that shovel can't solve can be solved in two parts. Otherwise, it will not be worth the loss of both machine and fuel consumption.

　　3.降低发动机转速

　　3. Reduce engine speed

　　虽然降低发动机转速会影响其工作能力，但可以大大降低油耗，提高油耗效率。当然，如果这不会导致效率低下，而效率低下又会导致雇主失去工作。

　　Although reducing engine speed will affect its working ability, it can greatly reduce fuel consumption and improve fuel consumption efficiency. Of course, if this doesn't lead to inefficiency, which in turn leads to employers losing their jobs.

　　4. 减小旋转角度

　　4. Reduce the rotation angle

　　减少自卸车装载时的转弯角度，可以缩短作业周期，增加单位时间的工作量，从而提高燃油消耗效率。

　　Reducing the turning angle of dump truck during loading can shorten the working cycle, increase the workload per unit time, and improve the efficiency of fuel consumption.

　　这也是更有效的省油方式，很多司机在装卸作业中，很多时候往往没有想到这一点，所以花了一部分不值得的油钱。

　　This is also the most effective way to save fuel. Many drivers often don't think of this in loading and unloading operations, so they spend a part of unworthy fuel money.

　　5. 走路时降低引擎速度

　　5. Reduce engine speed when walking

　　发动机转速越快，走路消耗的燃料越多。通过降低发动机运行速度，可以提高行走时的燃油消耗效率。

　　The faster the engine revs, the more fuel it uses to walk. By reducing the running speed of the engine, the fuel consumption efficiency can be improved.

　　6. 高水平的开采

　　6. High level mining

　　在开挖现场，先上后下的高开挖，与低开挖相比，周期时间缩短约12%，油耗提高约8%。

　　In the excavation site, the cycle time of high excavation is shortened by about 12% and the oil consumption is increased by about 8% compared with low excavation.
