SR液压泵SR100系列介绍
SR 液压泵系列是使用压缩空气运行的气动液压泵。 泵的排放压力由工作气压控制。 油流量在低液压时增加，在高液压时减少。 当气压与液压平衡时，泵自动停止，当液压降低时自动启动。 然后，泵连续运行，直到气压与液压达到平衡。
SR hydraulic pump series are air-over-hydraulic pumps operated with compressed air. Pump's discharge pressure is controlled by operating air pressure. Oil flow rate increases at the low hydraulic pressure and decreases at the high hydraulic pressure. When air pressure is balanced with hydraulic pressure, the pump stops automatically, and will start automatically when hydraulic pressure decreases. The pump, then, operates continuously until air pressure reaches equilibrium with hydraulic pressure.
