The number of wheel excavators in the domestic market is increasing, and the topic of wheel excavators is also heating up. Both demand customers and users are more and more concerned about the details of rotary excavation. After all, it is related to the advantages and disadvantages of competition and the sustainable income in the practical market. Among them, the fuel consumption of wheeled excavator is a more common and unavoidable substantive problem. Especially in the domestic wheel excavation market dominated by 8-ton models, what is the key point to determine the fuel consumption?
1. Influence of engine displacement
As an 8-ton wheeled excavator, the displacement of the diesel engine is basically about 2000ml, even if the engine displacement used by which brand has a high or low floating ratio. However, due to the limitation of wheel excavator model and the interference of power output and operation field, its displacement, horsepower and other parameters can not violate the supporting requirements of the objective environment.
It can be seen that the interference of engine displacement on the fuel consumption of similar wheel excavator models is also not the dominant factor. The working machinery is not a substitute tool. The link between the fuel consumption of different brand models and the response of the engine has been filled and covered up by too many more important interference factors, In addition, the diesel engines used by too many brand models of wheeled excavators are generally made in China and some are processed in China under the name of imported brands. There is little difference in their achievements and breakthroughs in fuel consumption.
2. Interference of operation habits and working conditions
For some mature wheeled excavator markets, fuel consumption has become a key point affecting the actual income in the fierce market competition. The same operator drives different brands of wheeled excavators; What is the conclusion that different operators drive the same wheel excavator under the same working condition?
Under the same working conditions, for drivers with similar operating experience, the impact of operating habits on the fuel consumption of wheeled excavators is also quite limited. After all, as experienced operators of wheeled excavators, they know how to drive to save fuel. In actual work, many people will avoid the phenomenon of useless fuel consumption.
3. Influence of wheel excavator brand and model design
Of course, this aspect always gives people Abstract macro concepts, and can not debate the details. In fact, it is not the case. In the domestic market, different brands of wheeled excavators have great differences in the design concept and professional level of excavator models.
We can easily distinguish it from the reflected value of fuel consumption, among which, the rationality of the organic combination of various components of the hydraulic system; Mechanical control of the force bearing point of the operating device; Whether the design parameters are changed under different working conditions, work power distribution and energy consumption output ratio are effective and reasonable links fully established in the nuances of each link, rather than blindly assembling and ignoring the compatibility of components, which will eventually lead to the fundamental and main factors of considerable fuel consumption difference for the same tonnage models of different wheel excavator brands.
