The ____ returns the pump operating rod to mid position as soon as the helmsman stops turning the wheel
A. hunting gear
B. cut-off level
C. servo-motor
D. swivel block
题目解答
答案
A. hunting gear
解析
在船舶的舵控制系统中,当舵手停止转动舵轮时,需要有一种机制能够将泵的操作杆返回到中间位置。这种机制被称为“hunting gear”(寻中装置),它确保了舵轮停止转动后,舵能够自动回到中位,从而保持船舶的直线航行。其他选项如“cut-off level”(切断水平)、“servo-motor”(伺服电机)和“swivel block”(旋转块)与该功能无关。
