SUMMIT BIBIYANAⅡ期1*344.908MW燃气蒸汽联合循环电厂 燃机运行规程3.3.1 盘车与停机后的检查3.3.3.1 盘车A. 机组停机过程，当转速下降到L14HR时，自动投入低速连续盘车B. 机组停机后需要盘车72小时C. 机组长期停运，没有投入盘车的情况下，应在开机前12小时内投入连续盘车D. 机组紧急跳机后的处理：Ÿ 跳机20分钟内,可以在盘车转速下再启动，可用正常的启动程序Ÿ 停机后20分钟到48小时的再启动，要在开机前盘车1~2小时Ÿ 机组一直停着，又没有投入盘车，必须在停机48小时后再启动，才不会使转子弯曲在停机期间，只要有可能应保持润滑油供应如果在再次启动前盘车时发现偏心度太大（≥0.05），则将转子从停止位置转动180°，以校正转子的瞬态弯曲状况，然后才可以连续盘车E. 遇到机组停机后亟需停盘车检修时：Ÿ 轮间温度在100℃以上时，可采用高速盘车办法来加速机组冷却Ÿ 轮间温度降到120℃以下，65.5℃以上，在得到总工级别以上领导批准后，可以停盘车抢修抢修结束后必须立即投入连续盘车，连续盘车投入后到轮机间听音检查，听音检查无异常后，机组高速盘车半小时再发停机令。

盘车投入后选择“Fire”方式发启动令启动过程中严密监视机组振动情况，机组点着火无异常后维持点火状态20分钟再发停机令待盘车投入后再高速盘车15分钟以上，以上步骤完成后，机组方可按正常方式启动；在机组启动过一阶临界时，严密监视机组的振动情况若最大振动大于10mm/s则立即发停机令待盘车投入后再转高速盘车15分钟，再按正常方式启动若一阶临界仍不合格，则重复以上步骤，直至一阶临界振动小于10mm/s，方允许机组继续升速Ÿ 轮间温度降到65.5℃以下，当班值长可下令停盘车，抢修结束后必须立即投入连续盘车，连续盘车投入后到轮机间听音检查，听音检查无异常后，机组经高速盘车半小时和连续盘车半小时以上方允许按正常方式起动机组在机组启动过一阶临界时最大振动大于10mm/s则立即发停机令盘车投入后选择“Fire”方式发启动令启动过程中严密监视机组振动情况，机组点着火无异常后维持点火状态20分钟再发停机令待盘车投入后再高速盘车15分钟以上，机组方可再按正常方式启动若一阶临界仍不合格，则重复以上步骤，直至一阶临界振动小于10mm/s，方允许机组继续升速3.3.3.2 停机后的检查A. 检查滑油泵运行正常，滑油母管压力正常；B. 检查顶轴油泵投入正常，顶轴油压正常；C. 检查机组应连续盘车；D. 检查冷却水泵运行正常，冷却水温、滑油温度正常；E. 检查油雾分离器抽烟机运行正常；F. 检查反吹投入正常；G. 在燃机冷机时在轴承冷下来前，必须继续提供润滑油并进行盘车。

盘车齿轮马达切断电源以前，润滑油泵不能停止运行；H. 当透平达到盘车转速时，可以停掉液压油动力单元；I. 只要发电机内有氢气，密封油必须维持在运行状态4．机组水洗4.1．水洗系统概述4.1.1 系统概述压气机的通流部分结垢或积盐会降低空气流量，降低压气机效率和压气机压比，并使机组的操作线向喘振边界线靠近压气机清洗则有助于除掉积垢和恢复机组性能压气机水洗分为和离线水洗清洗是当机组在基本负荷附近操作且压气机进口导叶在全开位置时，对压气机进行清洗离线清洗是机组停机后用清洗液对压气机进行清洗4.1.2 设备规范DeviceSystemSettings20TW-4 0442OFF-LINE COMPRESSOR WASH WATER INJ SOLENOID VALVEDE-ENERGIZED: 3 TO 1 OPEN; 2 PLUGGEDENERGIZED: 1 TO 2 OPEN; 3 PLUGGED125 VDC; 20.60 W; 0.1600 A;PART OF VA16-120TW-6 0442ON-LINE COMPRESSOR WASH WATER INJ SOLENOID VALVEDE-ENERGIZED: 3 TO 1 OPEN; 2 PLUGGEDENERGIZED: 1 TO 2 OPEN; 3 PLUGGED125 VDC; 20.60 W; 0.1600 A;PART OF VA16-320WDET 0442SOLENOID, 2 WAY VALVE TO RECIRCULATE WATER BACK TO TANK.230 VAC; 50 HZ;1 PH;DE-ENERGIZED: 1 TO 2 CLOSEDENERGIZED: 1 TO 2 OPENCONTROL SIGNAL NAME IS L20WDET.
