Energy Saving Technology Applications Of Bulldozer

Sep. 05, 2018

The bulldozer can separately perform excavation, earth moving and unloading work. It has the characteristics of flexible operation, convenient rotation, small working face and fast driving speed. So how is Hydrostatic Bulldozer energy-saving technology applied?

1. The hydraulic system of the working device adopts differential overflow technology. In this way, when the working device reversing valve is in the small opening throttle speed regulation process, the excess oil supply of the oil pump can be returned to the oil tank directly from the differential pressure valve without passing through the safety valve, so that the system pressure in the speed regulation process is only higher than the working pressure. The high value is ΔP, so as to reduce the hydraulic power loss and reduce the oil temperature.

2. Engine and working device hydraulic system and transmission system adopt full power matching technology. The engine can automatically adjust the power output to the transmission system and the hydraulic system of the working device according to the actual working conditions, so as to maximize the utilization of the engine power to achieve energy saving purposes.

3. Hydrostatic transmission technology. The drive is driven by static pressure. The whole machine reduces the transmission components such as gearbox, torque converter (master clutch) and steering clutch, which greatly reduces the mechanical power loss, and it is easy to achieve full power matching with the engine to achieve energy saving.
