Now the price of oil is getting higher and higher, and the profit of users is becoming less and less. How to save oil without reducing the working rate and the service life of machinery has become the most concerned problem. The following tips of oil-saving for excavators are the results of long-term comparative testing. The vast number of excavator users can refer to their daily construction situation.
Fuel consumption of excavators is a major item of daily cost expenditure
First, prevent engine idling
Even when it is idling, there will still be oil circulating in the hydraulic pump and consuming fuel. If one hour of the 10-hour working time in a day is idle, then if idling can be prevented, about 20 sound per month and about 230 litres of fuel can be saved annually.
Therefore, in the daily loading or excavation process, when the machine can be stopped for a long time in the middle, try not to idle with the excavator to "wait", to combine work and leisure, more fuel-saving, which is one of the key to oil-saving excavators.
2. Preventing Heavy Load Voltage Loss
当挖掘的沙土或石块负荷过重时，即使拉动操纵杆作业机械也无动作，而陷入失压状态。假如1 天10 小时的作业时间中有6 分钟为失压状态，那么，如果能防止失压，则每月可节省约70升，每年可节省约840升柴油，这一笔费用将近5000元的费用。
When the load of excavated sand or stone is too heavy, even if the manipulator is pulled, the machine will not move and will fall into a pressure-loss state. If 6 minutes of 10 hours'working time in a day is depressurized, then if depressurization can be prevented, about 70 litres of diesel oil can be saved per month and 840 litres of diesel oil can be saved per year, which cost nearly 5,000 yuan.
We all know that the problem that can not be solved by a shovel can be divided into two parts. Otherwise, it will take a lot of time and fuel to solve it.
Third, reduce engine speed
Although reducing the engine speed will affect the amount of work, it can significantly reduce the fuel consumption and improve the fuel efficiency. Of course, the premise is that it will not lead to inefficiency, in that case, it may cause employers'disgust and lose their jobs.
Fourth, reduce the angle of gyration
The key to saving oil for excavators is to reduce the swing angle and reduce the swing angle when loading dump trucks, which can shorten the operation cycle and increase the amount of work per unit time, thereby improving the burnup efficiency.
This is also the most effective way to save fuel. Many pilots are carrying out loading operations, which are often unexpected, so they spend a part of the unjust oil money.
Fifth, reduce engine speed while walking
The faster the engine rotates, the more fuel is consumed while walking. By reducing the engine speed during operation, the fuel consumption efficiency during walking can be improved.
6. Implementing High Level Excavation
在挖掘现场，首先挖掘位置较高的部分而后再挖掘位置较低的部分的高位挖掘与低位挖掘相比，可以缩短约12% 的周期用时并可提高约8% 的燃耗效率。
In the excavation site, compared with the low-level excavation, the high-level excavation can shorten the cycle time by about 12% and increase the burnup efficiency by about 8%.
