Simulation Analysis and Experiment of Variable-Displacement Asymmetric Axial Piston Pump
The variable displacement pump control system has greater energy-saving advantages and application prospects than the valve control system. However, the variable displacement pump control of differential cylinder is not concurrent with the existing technologies. The asymmetric pump-controlled cylinder is, therefore, used to balance the unequal volume flow through a single rod cylinder in closed...
متن کاملModeling and Performance Improvement of the Constant Power Regulator Systems in Variable Displacement Axial Piston Pump
An irregular performance of a mechanical-type constant power regulator is considered. In order to find the cause of an irregular discharge flow at the cut-off pressure area, modeling and numerical simulations are performed to observe dynamic behavior of internal parts of the constant power regulator system for a swashplate-type axial piston pump. The commercial numerical simulation software AME...
متن کاملNonlinear pressure control of self-supplied variable displacement axial piston pumps
The present paper deals with the pressure control of self-supplied variable displacement axial piston pumps subject to fast changing, unknown loads. First, the setup of the system and the mathematical model are described. As the pump is self-supplied, the mathematical model exhibits a switching right-hand side which makes the control design a challenging task. A nonlinear two degrees-of-freedom...
متن کاملAn Artificial Neural Network Flow Control of Variable Displacement Piston Pump with Pressure Compensation
One of the most important components in hydraulic circuits is the pump that generates hydraulic supply at constant pressure. The performance and the versatility of a variable displacement piston pump are, to a large extent, determined by its controller. Upgrading of existing controllers is considered one of the major means of improving the characteristics of the pump. The dynamic performance of...
