主蒸汽及高、低温再热蒸汽系统采用单元制系统，均采用“双管、单管、双管”的布置方式。主蒸汽管道和高温再热蒸汽管道分别从过热器和再热器的出口联箱的两侧引出，然后汇成一根母管，到汽轮机前再分成两根支管分别接入高压缸和中压缸左右侧主汽关断阀和再热关断阀。the oil level to the normal oil level. (2) for the secondary prevention of the leakage of cooling water pipe fittings, valve parts before installation to check ... 4.2 measures to eliminate quality defects of cables cable laying in front of the cable construction, design, supervision and construction units to deliver the design, and drawing the third. Combined the engineering field to find fault, adding omitted items. Because the unit used computer DCS control and adds a great deal of control and signal cables. So you should carefully review, checks for missing physical cable, ready for construction and to verify cable length, specifications, familiar with the cable channel and the device location and bracket cable bracket on the section number. At the time of preparation of the inventory of cable, first of all, the professional carefully study electrical schematics, in accordance with the principle of accounting the cable path cable volume, the number of cores used, total volume and design inventory check cable to cable with and without omission, laying of the cable in order to ensure the process does not put a cable one cable. Finally, at the time of inventory, prepared to take the same path the cables together. Inventory preparation is completed, later in each enclosure affixed on both sides of each side of the cable you want to lay accurately verify cable lengths and set aside. Bridge should be combined, correcting errors, avoid straight, no cable bridge scaffolding used in the construction, not allowed to use electricity (fire) cutting, fix cable tray, cable tray is not allowed as a welding ground connection or cable tray cannot be used for other processes
