Variable pump - variable motor speed regulation system process is equivalent to a quantitative variable pump motor control or dosing pump control variable motor, variable displacement pump, there is a system overflow big loss this way, adjust the system slow and did not play the potential of other shortcomings. To overcome these deficiencies, proposed variable pump - variable motor adaptive control algorithm. Variable speed pump motor for active closed-loop control, maintenance variable displacement pump, and realize variable displacement pump and variable motor while adjusting the variable motor for servo control based on variable displacement pump. Single neuron adaptive PID control algorithm variable pump control, sales variable pump, predictive adaptive control algorithms variable motor control. Given the variable pump - variable motor adaptive control algorithm basic principles and block diagrams, simulation and experimental results show that the algorithm can improve system response speed and reduce the overflow losses. Xuzhou Construction Machinery Factory Institute a multifunctional valve in axial piston variable displacement pump and fixed motor closed circuit hydrostatic system ten thousand Han Chi construction machinery often used SPV axial piston variable displacement pump with axial MF piston fixed motor closed circuit. This system makes construction machinery has an easy to install connections, transfer of power volume ratio, and with no change to the soft ... variable displacement pump | Hydraulic preferred crystal Chong | Finishing variable pump from Jinan Jing Chong Hydraulic Machinery Limited.
