通过改变转速实现液压泵恒功率控制的研究

Research on Hydraulic Pump Constant Power Control by Changing the Rotating Speed

该文对通过改变转速实现恒功率控制的研究,在原来电比例变量泵通过摆角恒功率控制的基础上,换成了定量泵,永磁电机和变频器。通过可编程可控制器控制变频器变频永磁电机变速,实现恒功率控制。

In this paper,the research on constant power control by changing the rotational speed is based on the original electric proportional variable pump through the swing angle constant power control,replaced by a quantitative pump,permanent magnet motor and frequency converter.The variable frequency permanent magnet motor shifting is controlled by the programmable controller to realize constant power control.
