2. The cooling water pipeline of the bearing shall be dredged and the pressure test shall be conducted for the whole system, and the test pressure shall not be less than 4 kgf / cm2 in general if the equipment technical documents are irregular and punctual.

3、清洁和查看调理组织，其滚动应灵敏。
3. Clean and check the conditioning tissue, its rolling should be sensitive.

4、整体机组的装置，应直接放置在基础上用成对斜垫铁找平。
4. The device of the whole unit shall be directly placed on the foundation and leveled with a pair of inclined sizing blocks.

5、现场拼装的机组，底座上的切削加工面应妥善维护，不该有锈蚀或操作，底座放置在基础上时，使用成对斜垫铁找平。
5. For the assembled unit on site, the cutting surface on the base shall be properly maintained, and there shall be no rust or operation. When the base is placed on the foundation, it shall be leveled with a pair of inclined sizing blocks.



6、轴承座与底座应紧密接合，纵向不水平度不该超越0.2/1000，用水平仪在主轴上丈量，横向不水平底不该超越0.3/1000，用水平仪在轴承座的水平平分面上丈量。
6. The bearing seat shall be closely connected with the base, and the longitudinal non levelness shall not exceed 0.2/1000. The horizontal meter shall be used to measure on the main shaft, the horizontal non horizontal bottom shall not exceed 0.3/1000, and the level meter shall be used to measure on the horizontal bisector of the bearing seat.

7、轴瓦研刮前应先将转子轴心线与机壳轴心线校对，一起调整叶轮与进气口间的空隙和主轴与机壳后侧板轴孔间的空隙，使其契合设备技能文件的规则。
7. Before the grinding and scraping of the bearing bush, the rotor axis and the casing axis shall be calibrated first, and the gap between the impeller and the air inlet and the gap between the main shaft and the shaft hole of the rear side plate of the casing shall be adjusted together, so as to conform to the rules of the equipment technical documents.

8、主轴和轴瓦拼装时，应按设备技能文件的规则进行查看。轴承盖与轴瓦间应保持0.03～0.04毫米的过盈(丈量轴瓦的外径和轴承座的内径)。
8. When assembling the main shaft and bearing bush, check according to the rules of the equipment skill file. An interference of 0.03-0.04mm shall be kept between the bearing cover and the bearing bush (measure the outer diameter of the bearing bush and the inner diameter of the bearing pedestal).



9、机壳拼装时，应以转子轴心线为基准找正机壳的方位并将叶轮进气口与机壳进气口间的轴向和径向空隙高速至设备技能文件规则的范围内，一起查看地脚螺栓是否紧固。其空隙值如设备技能文件无规守时，通常轴向空隙应为叶轮外径的1/100，，径向空隙应均匀分布，其数值应为叶轮外径的1.5/1000～3/1000(外径小者取大值)。调整时力求空隙值小一些，以进步风机功率。
