| Abstract: |
| The load sensing speed control hydraulic system is an important part of hose delivery system on underground explosive loading truck. This article describes three different hydraulic drive systems with load sensing function form their principle and characteristics. Each system takes advantage of hydraulic throttle, variable pump and variable motor respectively, through the hydraulic pressure sensing and rotation rate sensing, to form a closed-loop electro-hydraulic proportional control circuit. All the three systems could achieve the functional design requirements for load sensing speed control. |
