文档介绍：说明 Instruction
本船舵系由“贝克becker”舵叶、直式舵杆、舵套筒带舵承座、舵柄、往复式液压舵机等组成。到货状态全部为成品。
The rudder-line of ship is constituted by “becker” rudder blade 、straight type rudder stock 、rudder trunk 、tiller 、hydraulic steering gear etc. these parts are finished products.
舵杆、舵柄、舵叶到厂后至上船前,施工部门应对各部件机加工和人工研配表面进行仔细检查,发现问题应及时提出。
Rudder stock 、rudder blade 、tiller arrived yard before transferring to ship ,the construction department should check machining and fitting and lapping surfaces of these parts carefully ,if finding any problem ,to delivery it in time .

压装准备
Preparing for assembly
1认真检查螺母及舵杆螺纹,如有硬伤、飞刺及高点等缺陷,应用油石进行仔细修研直至螺纹表面光顺为止;
Check the threads of nut and the screws of rudder stock , if there are any defects ,we should repair the threads by hone .
2将舵叶锥孔及舵杆锥体部位进行彻底的清洁;
Clean the cone hole of rudder blade and the taper parts of rudder stock.
3按示意图四安装轴/径向液压泵及其软管;
Installing axial / radial direction hydraulic pumps and hoses .
4排除液压系统中的空气。
Remove the air of hydraulic system
(参见示意图一)

“0”位确定
Decide the zero point for rudder stock.
在下铸钢体上设置一个千分表(见图1).打开阀B,闭阀A,(轴向加压,径向不加压) 启动液压泵,直到压力表压力达到30bar压力表重新调零,,3~4点后停止,作图法求出l0 (见图3)。此点即为舵杆压装距离的起始点,即以此点为压装“0”位。
Fix a dial gauge on the lower casting steel, (see figure 2) open valve A and close valve B, push-up hydraulic nut, until the pressure up to 30 bar , renew adjust the dial gauge to zero .and plot value push-up length & push-up pressure
