Working principle of the utility model is: it is shown in Figure 2,
The first step, the pre-selection of boiler water filling equipment (selection electrically driven feed pump or vapour front pump, if drum pressure is greater than 0.5MPa
Locking pre-selection vapour front pump)
Second step closes the main water supply main road electrically operated gate of boiler；
Third step closes the main feed water by-pass of boiler and adjusts door；
4th step closes the main feed water by-pass electrically operated gate of boiler；
5th step,
Following operation is executed if preselecting electrically driven feed pump:
1) electrically driven feed pump startup function group, is called, investment electrically driven feed pump scoop tube automatically controls electrically driven feed pump outlet
Pressure is to 5.5MPa.
2), crawl is opened electrically driven feed pump and is exported electrically operated gate 3 seconds, the aperture 2% before electrically driven feed pump scoop tube aperture is greater than
When, the aperture of electrically driven feed pump outlet electrically operated gate is kept, is otherwise delayed 5 seconds, continues crawl electrically driven feed pump and exports electrically operated gate 3
Second, repetitive operation until electrically driven feed pump scoop tube aperture is greater than when aperture 2%, keeps electrically driven feed pump outlet electrically operated gate
Aperture
3), electrically driven feed pump outlet pressure and when water supply main-piping pressure deviation 0.2MPa, standard-sized sheet electrically driven feed pump outlet electricity
Dynamic door
Following operation is executed if preselecting vapour front pump:
1) vapour front pump startup function group, is called
2), crawl is opened steam feed pump and is exported electrically operated gate 5 seconds, when steam feed pump outlet pressure declines 0.3MPa, guarantor
