This article designed a displacement setting mechanism by the fixed quantity of valve model radial column piston as base pump.
以阀式径向柱塞定量泵为基泵设计了控制进油阻力的变量机构。
Close the door distribution discharge valve and, if cut-off valve is opened, pumping water to the piston from the pipeline until the pump output.
关闭分配阀卸料门，如有截止阀则打开，泵送清水至活塞从输送管输出端泵出为止。
Working principle: piston moves from left to right, form a negative pressure pump cylinder, the liquid tank into the pump by the inhalation valve cylinder.
工作原理：活塞自左向右移动时，泵缸内形成负压，则贮槽内液体经吸入阀进入泵缸内。
