Now the price of oil is comparable to the gold price, many of the machine friends have the trouble of the big oil consumption of the excavator. One day's excavator is open, and the fuel consumption is like burning money. How can the work be done and the fuel consumption can be saved efficiently?
The key to fuel saving is the details
It is very simple to develop good habits and reduce fuel consumption and work efficiency in practical work. This time we summed up a few tips, we can refer to their own daily construction conditions for reference:
Detail one: avoid doing invalid movements
The oil used to do invalid movements is one hundred percent waste. We should design a good construction method according to the situation of the construction site, do not do unnecessary rotation, try to take the soil in front of the car as far as possible, avoid rotation to the back door to get the soil, and the height of the excavator should be suitable, and the soil is not to be dug to dig.
In the process of construction, meet the very hard digging and unmovable working conditions, do not make brute force, or not only do useless work, but also cause hydraulic oil overflow.
Detail two: high level mining
The excavator working platform is the most effective when it is high or slightly higher than the truck. Why do you say that mining in a high position can save oil? In fact, this is very well understood. If you are allowed to deliver things, and let you walk on stools to deliver things, which is less effort? The same is true for excavators. The more energy it saves, the lower the fuel consumption.
Detail three: reasonable control of the mining angle
When the bucket oil cylinder and connecting rod, rod cylinder and bucket rod are all 90 degrees, the maximum power of each excavator is pushed by each cylinder. When digging at the beginning, do not extend the bucket to the maximum range. The effect is best from about 80%.
Detail four: low fuel control knob
When the walking mode is in the Hi mode and the fuel control knob is in the MAX position, if the machine continues to walk for more than 2 minutes, it will show the walking mode suggestion information. When you walk for a long time, you can reduce fuel consumption by lowering the fuel control knob.
After 10 seconds or press the switch F5, the walking mode suggestion information will disappear.
Of course, if you are a local tyrant, you can go wherever you like.
But we need to remind you for a long time and high speed, it will also cause high temperature of the heavy wheel because of continuous friction, so that the lubricating oil in the support wheel is heated and expanded. It may cause the oil seal of the rotary ring oil seal to be damaged and leak oil. It is suggested that you take 15 minutes to walk in general condition, and stop for 15 minutes in the way of rotation to do the walking operation. When you come to different roads and slopes, you have to rely on yourself.
Detail five: try to avoid engine idle
Even in idling, there is still oil in the hydraulic pump that circulates and consumes fuel. If there are 1 hours of 1 days and 10 hours of operation in the empty rotation, then, if can prevent the empty turn, it can save about 20 sound per month and save about 230 liters of fuel every year. Therefore, in the process of daily loading or mining, when the midway can be stopped for a long time, try not to open the idle "waiting" at the excavator.
Detail six: reduce the rotation angle
Reducing the roundabout angle when loading to dump trucks can shorten the operation cycle and increase the amount of work in unit time, thereby enhancing burnup efficiency. This is also the most effective way to save oil, many machine hands in the loading operation, many times often do not think of this, and therefore spend a part of the oil money.
Detail seven: try to excavate 90 degrees as much as possible
I believe this, as long as you have taken a theoretical class, the book, including teachers, should be told. But in real life, there are few people who go to school to learn technology. Most of them are born in the middle of the road and learn from private masters. The 90 degree excavator means that the bucket is used in the largest range. It's like digging things with your hands. Only digging is the best way to save energy.
When the bucket oil cylinder and connecting rod, rod cylinder and bucket rod are all 90 degrees, the maximum power of each excavator is pushed by each cylinder. When digging at the beginning, do not extend the bucket to the maximum range. The effect is best from about 80%.
Detail eight: avoid heavy load drop
When excavated sand or stones are overloaded, the excavator will fall into a state of collapse. It is assumed that there are 6 minutes for 10 hours of work in 1 days to reduce the pressure. If the pressure drop can be avoided, it seems to be insignificant and can save about 840 liters of diesel every year. The operation of pressure drop will not only cost oil, but also cost the machine.
These small skills in the oil saving operation may not even be noticed by the old machine hands, but as long as they are able to develop good operating habits, they can actually save a considerable amount of oil.
The operation of the manipulator is the key to the oil saving. In some cases, reducing the error can effectively save oil. Saving fuel requires the operator to spend the effort on every detail. Perhaps a little effort in an action can make the work better.
Construction machinery is big, fuel consumption is huge, and fuel prices are rising, which also seriously affects the income of the excavators. When chatting, you will find that some old drivers drive oil saving, and your excavator is more oil burning than others. In fact, the old drivers have such a set of oil saving skills, which can ensure the efficiency and service life of the equipment, and save fuel.
