The invention discloses a hydraulic excavator fuel consumption testing system and method. An electronic weighing fuel tank is used for detecting the change of amount of fuel in a fuel tank. A collector is used for detecting the temperature, pressure and flow of the system through a plurality of temperature sensors, pressure sensors and flowmeters, wherein the load of an excavator can be calculatedbased on the pressure and flow. The temperature sensors are used for detecting the temperature of the systems and dissipating heat through heat dissipation devices. In testing, load data are obtainedthrough actual excavation of the excavator and processed into a load spectrum capable of being repeatedly implemented by a control system, the load spectrum is input into the testing system at the stage of calling the load spectrum, load spectrum data are converted into actual loads and input into all pumps of the hydraulic excavator through proportional overflow valves and proportional pressurereducing valves in the loading test process, and in the testing process, the load data are simulated and fuel consumption data are measured in real time. The hydraulic excavator fuel consumption testing system and method are free of real soil excavation and has good testing repeatability and reproducibility, and testing results are not affected by the external environment.
Description
technical field [0001] The invention relates to the application field of hydraulic excavator test technology, in particular to a hydraulic excavator fuel consumption test system and method. Background technique [0002] At present, various manufacturers have not formed a unified method for the fuel consumption test of hydraulic excavators. The practice of domestic manufacturers, including companies, is to use the operator to operate the excavator to actually excavate the soil, and test the fuel consumption before and after the test. This method mainly has the following disadvantages: affected by human factors, each excavation action is not uniform, the amount of excavation is different each time, the repeatability and reproducibility of the test process are relatively poor, limited by weather conditions, and the density of excavated soil caused by rain and snow, etc. Changes, the test results are greatly affected by the weather, and the test preparations such as excavation, ...
