PCY恒压变量泵液压系统四对轧辊缸动矫直机泵站的设计

Design of pump station with PCY constant pressure variable pump for hydraulic four-pair-roller straightening machine

在现有矫直机的基础上,进行四对轧辊缸动矫直机泵站部分的设计,采用PCY恒压变量轴向柱塞泵液压系统,通过改变流量来保证系统压力的恒定,从而提高系统的效率,达到有效节能的目的。

This paper designs pump station for four- pair- roller straightening machine. The pump station adopts PCY constant pressure variable axial piston pump to enhance the system efficiency and save energy by changing flow to keep system pressure constant.
