1设备及概况Equipment and Overview
菲律宾塞米拉拉项目1×15MW机组采用杭州汽轮机厂制造的NK40/56/25型汽轮机，南阳防爆集团股份有限公司生产的QFW-15-4型汽轮发电机，冲洗的范围包括：润滑油系统和部分控制油系统。
THE 1X15MW SEMIRARA CFB POWER PLANT PROJECT uses NK40/56/25 steam turbine generators manufactured by HANGZHOU STEAM TURBINE CO., LTD, and QFW-15-4 steam turbine generators manufactured by NAN YANG EXPLOSION PROTECTION GROUP CO., LTD. of which the flushing scope includes: lubricating oil system and part of control oil system.
2油循环前具备条件Conditions Provided before Oil Circulation
1)所有碳钢材料的管道和管件，必须经过酸洗。辅助油箱打磨temperary tank 20 m3
1) All carbon steel pipes and fittings should be subjected to acid pickling.
2)所有不锈钢材料的管道和管件，油循环之前，必须经过严格吹扫（最好蒸汽吹扫），且吹扫后采取特殊措施，用干净的绸布对管道内部进行擦洗。完成后对内壁进行检查。必须没有灰尘，管壁清洁
2) All stainless steel pipes and fittings must be purged with compressed air prior to installation and protected by taking special measures after purging, while the inside of them must be cleaned by wiping with clean rag.
3）主油箱的清扫：把油箱内部彻底清扫干净，先用白布，然后再用面团。在油箱底部和回油的处加装磁棒。
3) Main tank cleaning: the tank must be thoroughly cleaned inside with a white cloth first and then dough. The bar magnets must be installed at the tank bottom and the scavenge filter screen.
4）在汽机房安装二台L Y-150压力式滤油机（含5000张滤油纸300mm ×300mm），进口接主油箱疏油口一次门门前，出口接在主油箱人孔门上并联在主油箱上。
4) A LY-150 pressure oil filter (containing 5000 filter papers, 300mm x 300mm) is to be installed at 0m in the turbine generator room with the inlet connected to the main tank in front of the primary door of oleophobic outlet, and the outlet connected to the main tank manhole door and to the main tank in parallel.
5）汽轮机和发电机轴承：将所有支持轴承上半部均拆除，支撑轴承下半部不动，推力轴承的推力板拆除。
5) Turbine and generator bearings: remove the upper halves of all support bearings with their lower halves remained in original positions, and remove the thrust plates of thrust bearings.
6）润滑油系统：将润滑油管道与轴承座脱开，将进回油管用临时短管连接起来,在主油泵吸入口和出口处加堵板。
6) Lubricating oil system: the oil pipes are disconnected from the bearing seats, the inlet and return oil pipes are connected together with a temporary short tube. Add blind plate on suction inlet and outlet of main oil pump.
7）控制油系统：速关组件进回油管用临时管道连接起来。
7) Control oil system: the inlet and return pipes of quick closing assembly are connected together with a temporary tube.
8）上油前的系统检查：油箱上油前必须会同热工共同检查，确认系统连接正确无误，各热工测点安装正确无遗漏，油箱油位指示器灵活，其指示与油箱中的实际油位应相符合，做好防尘、防溅、防漏措施。除必要的压力、温度监测点外，油系统其它仪表点应隔离。
8) System check before oil supply: the oil tank must be jointly checked with a I&C engineer before starting oil supply to confirm that the system connection is correct, the thermal measurement points are installed correctly and completely, and the tank oil level indicator is sensitive where the indication should be consistent with the actual oil level in the tank; the system should be protected by taking proper measures of dust, splash and leakage prevention. In addition to the necessary pressure and temperature monitoring points, the other instrument
