Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, in prior art, transformer station's boiler water filling device, including condenser 1, oxygen-eliminating device 3, economizer 5 and
Drum 8, condenser 1, condensate pump 2, oxygen-eliminating device 3 and economizer 5 pass sequentially through pipeline connect, described economizer 5 input with
Drum 8 connects, and economizer input pipeline arranges economizer circulation valve 6, and described economizer 5 outfan is connected with drum 8,
Described drum 8, water-cooling wall lower collecting box 10 and water-cooling wall upper header 9 pass sequentially through pipeline and connect.
Above-mentioned transformer station boiler water filling device work process is:
Step one, water on condenser, upper water starts condensate pump 2 water on oxygen-eliminating device 3 after terminating；
Step 2, after oxygen-eliminating device 3 water level is normal, starts feed pump 4, opens motor regulated valve 7, with scoop tube and circulation
Valve 6 controls upper water speed, during upper water to-100mm, water in stopping；
Step 3, closes motor regulated valve 7 and circulation valve 6 and scoop tube；
Step 4, stops feed pump 4, opens economizer 5.
As in figure 2 it is shown, a kind of energy-saving transformer substation boiler water filling device, including drain tank 11, drainage pump 12, economizer 5
With drum 8, drain tank 11 entrance input demineralized water, drain tank 11 outlet connects with drainage pump 12 entrance, and drainage pump 12 first goes out
Mouth arranges water total valve 13, and the outlet of described drain tank 11 second is connected with economizer 5 entrance, and described drain tank 11 second exports
Setting discharges water total valve 16, and economizer 5 entrance arranges economizer Draw off valve, and economizer exit is connected with drum 8 first entrance,
Described drum 8, water-cooling wall lower collecting box 10 and water-cooling wall upper header 9 pass sequentially through pipeline and connect, water-cooling wall lower collecting box 10 inlet tube
