原理: 高频功率放大器用于发射机的末级,作用是将高频已调波信号进行功率放大,以满足发送功率的要求,然后经过天线将其辐射到空间,保证在一定区域内的接收机可以接收到满意的信号电平,并且不干扰相邻信道的通信。高频功率放大器是通信系统中发送装置的重要组件。按其工作频带的宽窄划分为窄带高频功率放大器和宽带高频功率放大器两种,窄带高频功率放大器通常以具有选频滤波作用的选频电路作为输出回路,故又称为调谐功率放大器或谐振功率放大器;宽带高频功率放大器的输出电路则是传输线变压器或其他宽带匹配电路,因此又称为非调谐功率放大器。
比例控制技术是在开关控制技术和伺服控制技术之间的过渡技术,采用比例放大器控制比例电磁铁,实现对比例阀的连续控制,从而实现对液压系统压力、流量、方向的无级调节;但是用比例方向阀进行速度控制时,如果负载是变化的,那么执行元件的速度就会受负载变化的影响(负载小时速度快,负载大时速度慢);于是在系统设计时,人们引入了压力补偿器,它可以使比例阀阀口的压差保持恒定,使执行元件的速度不受负载变化的影响。
某钢厂步进梁式加热炉中步进梁升降液压回路。 此回路使用了比例方向阀与进口压力补偿。 由于步进梁下降时,存在超越负载,所以在油缸无杆腔设置了平衡阀。 压力补偿器的弹簧调定后(这里为定值),比例阀节流口的压差 Δp 就近似为恒定值,即比例方向阀进油口前后压差 Δp 保持恒定值。 当节流口前后压差保持不变时,通过节流口的流量只与节流口的开口面积成正比。 对比例方向阀而言, 进油节流口的开口面积与比例方向阀的输入电流信号有关,而与负载的变化无关。 亦即升降油缸的供油流量 Q 只与比例方向阀的输入电流信号有关,与负载的变化无关。
补偿器主要用于节流调速系统 ,即补偿比例阀口的压差,在定量泵系统中得到了广泛的应用;但这种应用不可避免地会产生一定的溢流损失;如果二通压力补偿器与泵控压力补偿器配合使用,则可以实现容积节流调速。
变量泵+比例多路阀的形式, 组成了负载敏感回路;除每一联多路阀都设有进口压力补偿器外;变量泵还配有泵控压力补偿器;此补偿器与反馈油路配合可实现负载敏感控制, 使此回路不仅降低了比例阀阀口的节流损失,也将液压系统的溢流损失降到低。
