Energy-saving matching strategy and experimental study of pumping system for truck-mounted concrete pump

Aiming at the high fuel consumption and use-cost of truck-mounted concrete pump, an energy-saving matching strategy of pumping system is presented and the experimental study is conducted. Since pumping system occupies most resources of engine, the matching strategy between engine and main pump is analyzed to meet the load demand and reduce the engine rational speed drop. The testing method is established to measure the fuel consumption of engine under various working conditions, and the experimental data are analyzed to find the law of the fuel consumption of engine. The system performance can be improved by adjusting the system input value. Finally, the energy-saving matching strategy is established to reduce the fuel consumption of truck for unit workload, which provides a new approach for the energy-saving of truck-mounted concrete pump.
