Description
условии сохранени указаннсго соотношени эффективных площадей.condition of preservation of the specified ratio of effective areas.
При увеличении расхода пара в отбор перепад давлений на ступени 7 увеличиваетс и одновременно уменьшаетс давление перед ступенью (если перепад меньше критического ). При этом перемещение штока 14, пропорциональное изменению вырабатываемой ступенью 7 мощности, передаетс через усилитель 15 на клапан 16. Последний прикрываетс , ограничива расход пара в отбор и восстанавливает допустимую мощность ступени 7.With an increase in the consumption of steam in the selection, the pressure drop at step 7 increases and at the same time the pressure in front of the step decreases (if the drop is less than the critical one). In this case, the movement of the rod 14, proportional to the change in the power output by stage 7, is transmitted through the amplifier 15 to the valve 16. The latter closes itself, limiting the flow of steam into the extraction and restores the allowable power of stage 7.
Описанна система характеризуетс повышенной точностью срабатывани защиты, чтоThe described system is characterized by increased accuracy of protection, that
позвол ет повысить надежность работы паротурбинных установок.allows to increase the reliability of steam turbine installations.
