The hydraulic synchronizing system comprises an oil pump, a split-flow motor, a control valve group, an emergency valve group, a first balance valve group, a second balance valve group, a first hydraulic oil cylinder and a second hydraulic oil cylinder, the control valve group comprises a control valve connected with the oil pump, and a first logic valve and a second logic valve which are respectively connected with the control valve; the positions of valve cores in the first logic valve and the second logic valve are controlled by operating the control valve; the oil pump conveys hydraulic oil from the oil tank to the control valve and the emergency valve set, the control valve guides the hydraulic oil into the control ends of the first logic valve and the second logic valve, and the positions of valve elements in the first logic valve and the second logic valve are changed. And the emergency valve group discharges hydraulic oil output by the oil pump into the first hydraulic oil cylinder and the second hydraulic oil cylinder through the first balance valve group and the second balance valve group by the shunting motor through the first logic valve and the second logic valve. Synchronous stretching and retracting of the two independent hydraulic oil cylinders are achieved through the single flow dividing motor.

    一种救生艇双吊艇臂液压同步系统包括油泵,分流马达,控制阀组,应急阀组,第一平衡阀组,第二平衡阀组,第一液压油缸,第二液压油缸;控制阀组包括与油泵连接的控制阀,以及与控制阀分别连接的第一逻辑阀和第二逻辑阀;通过操作控制阀控制第一逻辑阀和第二逻辑阀内阀芯的位置;油泵将液压油从油箱输送至控制阀和应急阀组,控制阀将液压油分别导入至第一逻辑阀和第二逻辑阀的控制端,实现第一逻辑阀和第二逻辑阀内阀芯的位置改变;应急阀组将油泵输出的液压油通过分流马达将液压油经第一逻辑阀和第二逻辑阀,通过第一平衡阀组和第二平衡阀组分别排入第一液压油缸和第二液压油缸。本发明通过单个分流马达实现了2个独立液压油缸的同步伸缩。
