货油泵安装工艺

1. 在分段EB02上安装前的条件

Condition before mounting on the subsection EB02.

1) 货油泵的基座按基座图(图号：H012-101-02)安装到位.

Seat for cargo pump must be installed completely, according to pump

seat drawing (H012-101-03).

2) 将泵安装到基座上，并且垫块拂配结束。

Put the pump on the seat and the chock must be finished.

3) 垫块交船东认可，按图纸钻孔达到图纸规定尺寸。

Application inspection the chock to owner and surveyor. Boring the

holes according to the drawing.

4) 紧固货油泵联接螺栓。

Tighten cargo oil pump bolts.

2. 在船台上安装前的条件

Condition before mounting on the slipway.

1）机舱EG43，EG41及EG42分段所有工作全部完工。

Welding work for block EG43, EG41 and EG42 must all be finished.

3. 透平基座的安装步骤

Installation process of turbine foundation

1）泵舱顶平台的透平安装位置开Φ200孔。不能开到实际大小，开小孔以便于安装时调节整体误差。

Hole for cargo pump on pump room top platform first should be cut Φ

200 in order to easy to adjust.

2）透平机基座放置到位，点焊。高度误差不超过±5mm。

The seat for turbine only need be touched welding. The permissible error

of height no more than±5mm.

3）用铅垂从泵舱顶开孔处放下，校准货油泵基座中心位置以确定泵舱顶平台开孔圆心位置。

Align the center of cargo pump foundation with a plumb from the hole on

pump room top, and then find the real center point of the hole.

4）根据已确定的圆心位置开Φ580孔。

Cut Φ580 hole according to the center of the hole that just found.

5）根据已确定的圆心位置确定透平基座位置，并将透平基座安装到位。高度误差不超过±5mm。

Install the foundation of the turbine completely according the center of

the hole that just found. The permissible error of height no more than±

5mm.

4. 货油泵的安装步骤

Installation process of cargo pump

1）按图①所示加工一临时轴，确保两端法兰的同轴度不超过0.05。

Machining a temporary shaft refer to the figure ①，keep the same axial angle not more than 0.05mm.

2）将通舱联轴节与6420平台焊接，焊接过程中注意对称焊接，以防止不锈钢波纹管的变形。

Welding the intermediate shafting of penetration with the 6420 platform, to be prevent deformation give to the stainless bellow by welding must be keep symmetry welding.

3）将货油泵组按图②初步布置到位，同时用调整螺钉支承，将临时轴与货油泵固定并用联接螺栓固定,按照货油泵的输出轴来校正。

Installing the cargo oil pump and support by adjusting bolts, and fitting temporary shaft with cargo oil pump tightly by bolts，shaft alignment according to the output shaft of cargo oil pump.

4）根据图③所示将通舱件安装到位，确保联轴节的两端的平面距离距6420平台上表面的距离达到如图③所示的要求，在安装过程中要确保通舱联轴节的不锈钢波形管保持自由安装状态。

Installing the penetration stuffing box refer to drawing ③. Keep the distance from the both end surface to the 6420 platform as figure ③shown. And keep the stainless free in the install process.

5）通过调整通舱件与货油泵的相对位置达到如图④所示的要求，确保中心偏移误差，法兰间开口误差＜0.4mm。

Adjusting the intermediate shaft according to figure ④. Keep the coupling parallel misalignment and angular misalignment less than 0.4 mm.

6）将涡轮机组的输出轴的法兰安装到位，同时用调节螺钉调整涡轮机组，确保输出轴与中间轴法兰偏差＜0.2mm，见图④所示。

Fitting the coupling for turbine and support by adjusting bolts, keep the permissible error between the output shaft and intermediate shaft less than 0.2mm, refer to drawing ④.

7）将涡轮机组的各垫块安装到位，同时交船东、船检认可，按图纸钻孔达到图纸规定尺寸。

Fitting the chocks for turbine with foundation and inspection by owner and surveyor boring the holes according to the drawing.

8）浮动联轴节的安装

The mounting of the floating coupling

浮动联轴节的安装前首先将通舱件处的联轴节与输出端的法兰联接好并

紧固，浮动轴安装时应注意浮动联轴节的一端标有“C”应向上与联轴节

联接，标有“PC”的一端应向下与货油泵联接。参见图⑤。

The coupling in penetration and the flange in output to be continued and
