2、ons(fill in and execute base on working sequence)操作危险点、安全措施和注意事项(按工作顺序填写与执行)1当小机转数小于3000r/min以下时，方可小机打闸。低转速时停留时 间不要太长，防止机械密封损坏。When the rolling speed of BFPT less than 3000r/min, then BFPT trip. Low rolling speed duration time should not be long, preventing mechanical seal damage.2当小机停止后，方可停止汽泵前置泵运行
3、。When BFPT stop, then stop steam pump booster pump operating.3小机停止后，禁止带泵 起盘车运行。BFPT stop, forbid put turning gear into service with pump.4汽泵停止后，根据实际情况停止相应小机轴封运行。油系统必须运行 4小时后才可以停止。TBFP stop, then stop relevant BFPT gland sealing operation based on actual situation. Oil system should operate for four
4、hours then stop.-二二Operation Item(fill in and execute base on working sequence) 操作项目(按操作顺序填写与执行)1得值长令，号机汽动给水泵组停运。Receive shift in charge engineers order, # unit # TBFP stop serve.2确认其它运行给水泵中间抽头门()确在全开位置。Confirm other operating feed water pump intermediate stage bleedoff valve in full open position.3
5、关闭号机汽动给水泵中间抽头门。Close # unit #TBFP intermediate stage bleedoff isolating valve.4将号机汽动给水泵转速切至“手动”方式。Switch # unit # TBFP rolling speed to manual mode.5开启小机所有疏水阀.Start all the drain water valve of BFPT.6逐步降低号机汽动给水泵转速，将负荷平稳地移至另一台汽动给水泵或电动给水泵。Gradually decrease rolling speed of #_ unit #_ TBFP, and transf

8、it #TBFP recirculating valve open, load is all removed, closeTBFP outlet motor valve.9解除遥控，转速控制将被切至MEH“自动”方式，在MEH下继续降转速至 3000 rpm.Release remote control, rolling speed control will be switch to MEH automation mode, in MEH mode decrease rolling speed to 3000 rpm.10转速到3000 rpm以下时，手动脱扣汽动给水泵，检查小汽机主汽门、 调
9、速汽门、四抽电动进汽门()、辅汽进汽门()关闭，转速下降，记录惰走时间。When rolling speed is below 3000 rpm, manually trip TBFP, inspect BFPT main steam valve, governing valve, 4th extraction motor steam inlet valve, auxiliary steam inlet valve close, rolling speed decrease, record coasting time.11停运 号机汽泵前置泵。关闭小机除轴封汽管道疏水阀所有疏水阀。Stop #
10、_unit #_ steam pump booster pump. Close BFPT all drain water valve except gland sealing steam pipe water drain valve.12根据具体情况关闭小机排汽蝶阀()和_小机轴封进汽门()。Close BFPT gas exhaust butterfly valve and BFPT gland sealing steam inlet valve based on actual situation.13油系统运行四小时后，根据具体情况停运。After oil system operating for four hours, stop it based on actual situation.14操作结束，汇报值长。Operation finish, report to shift in charge engineer.Remarks备注：操作人(Operator)监护人(Supervisor)值班负责人(Responsible):值长(Shift-chief):
