A4VSO泵具有泵具有噪音低、体积小、自吸能力好、可靠性高等优点。在闭式系统上应用,油泵变量过零位时一般柱塞泵都有托盘现象,唯独D-A4VSO泵有效解决此类问题,因补油泵、控制泵可以串接、控制阀可以集成在泵盖上,其结构非常紧凑;另外,比例泵均带有位移传感器闭式反馈回路,其零位控制精度非常高。广泛应用于:冶金行业、锻压行业、船舶行业、船舶等等领域。A4VSO系列规格有40、71、125、180、250:;变量形式有恒压,恒功率、液动、负载感应、比例、伺服、压力流量复合控制形式;有开式系统泵和闭式系统泵。A10-FR01B-12,A10-FR01C-12,A10-FR01H-12,

图2ATMEGA16外部引脚图3输入信号处理软件的设计因整个系统对电压、电流采样的精度要求不高,我们直接用CPU的1位A/D对电压、电流的信号进行A/D转换,转换的结果一方面供显示的需要,另一方面作为过压与欠流的比较信号。我们将INT设置为上升沿产生异步中断,ICP设置为上升沿触发输入捕捉。当INT产生中断时,16位计数器开始以内部恒定的频率开始计数,直到下一中断的产生。在计数的同时,当TCP上有上升沿脉冲时,即将16位计数器已计得的数据放入到捕捉寄存器中。
