Working arrangement of starting up: 1. Starting from the duty of duty to the boiler before firing: The automobile monitor should check the end of the relevant working tickets for the unit to be opened, and the work that has no influence on the machine will be turned on. Check the steam turbine in standby, the oil quality is qualified, the oil level is normal. All the tests in the boot test manual are completed normally; Main engine lube oil, sealing oil, EH oil, internal cold water, compressed air, circulating water, open closed water, condensate water, water supply, auxiliary steam etc. The disk drive has been running normally (hot start running no less than 4 hours); Vacuum up to 40kpa; The main parameters of the steam turbine before starting up. 2. Before the boiler is fired to the flush: Input the bypass system, the hydrophobic system and the platoon system; Restore the oil system; High and low water side; Confirm that all other host protection is input except for low vacuum and machine hop furnace. Check the steam turbine body and the metal temperature of each extraction pipe. The vacuum is maintained for 60 ~ 80kpa. 3. Before and after the flush: Check the disc car and the top axle oil pump automatically shutdown; Input low gas side; Automatic injection of water spray; Start the cold oil for the pump; The switch and the rated speed are normal; Check turbine vibration, axial displacement, differential expansion, total expansion and other normal. 4. After network: According to the rules and regulations, load, pump, steam pump, etc., to carry out a thorough inspection of the turbine system; Input machine jumping and low vacuum protection. Ii. Work arrangement before shutdown: 1. Try to start the host ac, dc oil pump, low oil pump, top axle oil pump, no-load starter m
