The permissible

4、 error of height no more than±5mm.3） 用鉛垂從泵艙頂開孔處放下，按照壓載泵輸出軸中心位置以確定泵艙頂平臺開孔圓心位置。According the center of the output shaft of ballast with a plumb from the hole on pump room top, and then find the real center point of the hole. 4） 根據已確定的圓心位置開580孔。 Cut 580 hole according to the center of the hole tha

5、t just found. 5） 根據已確定的圓心位置確定電動機透平基座位置，并將透平基座安裝到位。高度誤差不超過±5mm。Install the foundation of the motor completely according the center of the hole that just found. The permissible error of height no more than±5mm.4. 壓載泵的安裝步驟Installation process of ballast pump 1） 按圖所示加工一臨時軸，確保兩端法蘭的同軸度不超過0.05。Ma

6、chining a temporary shaft refer to the figure ，keep the same axial angle not more than 0.05mm.2） 將通艙聯(lián)軸節(jié)與6420平臺焊接，焊接過程中注意對稱焊接，以防止不銹鋼波紋管的變形。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 w

7、elding.3） 將電動機機組按圖初步布置到位，同時用調整螺釘支承，將臨時軸與貨油泵固定并用聯(lián)接螺栓固定,按照壓載泵的輸出軸來校正。 Installing the motor and support by adjusting bolts, and fitting temporary shaft with ballast pump tightly by bolts，shaft alignment according to the output shaft of ballast pump.4） 根據圖所示將通艙件安裝到位，確保聯(lián)軸節(jié)的兩端的平面距離距6420平臺上表面的距離達到如圖所示的要求，在

8、安裝過程中要確保通艙聯(lián)軸節(jié)的不銹鋼波形管保持自由安裝狀態(tài)。 Installing the penetration stuffing box refer to drawing . Keep the distance from the both end surface to the 6420 platform as figure shown. And keep the stainless free in the install process.5） 通過調整通艙件與壓載泵的相對位置達到如圖所示的要求，確保中心偏移誤差，法蘭間開口誤差0.4mm。 Adjusting the intermediate

9、 shaft according to figure . Keep the coupling parallel misalignment and angular misalignment less than 0.4 mm. 6） 將電動機機組的輸出軸的法蘭安裝到位，同時用調節(jié)螺釘調整渦輪機組，確保輸出軸與中間軸法蘭偏差0.2mm，見圖所示。 Fitting the coupling for motor and support by adjusting bolts, keep the permissible error between the output shaft and intermedi

10、ate shaft less than 0.2mm, refer to drawing .7） 將渦輪機組的各墊塊安裝到位，同時交船東、船檢認可，按圖紙鉆孔達到圖紙規(guī)定尺寸。Fitting the chocks for turbine with foundation and inspection by owner and surveyor boring the holes according to the drawing.8） 浮動聯(lián)軸節(jié)的安裝The mounting of the floating coupling 浮動聯(lián)軸節(jié)的安裝前首先將通艙件處的聯(lián)軸節(jié)與輸出端的法蘭聯(lián)接好并緊固，浮動軸安

11、裝時應注意浮動聯(lián)軸節(jié)的一端標有“C”應向上與聯(lián)軸節(jié)聯(lián)接，標有“PC”的一端應向下與貨油泵聯(lián)接。參見圖。The coupling in penetration and the flange in output to be continued and tightened correctly before mounted the floating shaft. It is therefore special attention should be paid for that the floating shaft with the coupling marked with “C” is to be f

12、itted up and the other side marked with “PC” fitted down with cargo oil pump. Reference to figure .5. 安裝過程中允許的誤差 Permissible deformation1） 垂直方向的伸長誤差±10mm。 Elongation or contract in vertical direction±10mm。2） 角度偏差5 。（見圖） Angle deviation 5 (See figure ).3） 垂直方向的偏差±8mm（見圖）。 Perpendicular

13、 deviation ±8mm (See figure ).6. 壓載泵外接管路的注意事項 Caution for piping 錯誤的管路布置引起的外力作用導致泵的變形不僅引起振動而且導致泵的故障，因此排出與吸入側的法蘭聯(lián)接必須正確的相配，必須避免如圖所示的聯(lián)接，導致在泵側的不合理的外力，也不必讓泵由于管重量和熱膨脹而產生變形。Deformation given to the pump by outside force due to incorrect piping cause not only vibration but also pump troubles. Therefore

14、, the pipe flanges connecting with the suction and discharge nozzles must be correctly matched. Be sure to avoid the cades shown in fig. Otherwise the pump may receive unreasonable force. Nor must the pump be directly given deformation due to the total weight of piping and thermal expansion.7. 吸入管 S

15、UCTION PIPING 吸入側的管路很大程度上影響泵的效率，為避免故障的出現(xiàn)，必須從以下幾個方面考慮。The piping on the suction side affects pump efficiency to a grate degree and to avoid troubles arising there from the following points must be noted.1） 管路中必須沒有氣穴的形成。 No air pocket must be formed in the piping.2） 與管路聯(lián)接的管路附件確保氣密防止氣體進入。 All fittings in the piping must be perfectly tightened to prevent air invasion.3） 防止管路上閥件的填料泄漏。 Care must be taken to prevent air leakage through glands of
