Изобретение относитс  к средствам автоматизации конденсационных установок.This invention relates to automation equipment for condensing units.

Известны устройства дл  автоматического регулировани  турбопривода циркул ционного насоса пароэнергетической установки, содержащие регул тор температуры конденсата с задатчиком и регулирующим клапаном турбопривода . Однако в таких устройствах производительность насоса определ етс  только паровой нагрузкой конденсатора, а изменение температуры охлаждающей воды не учитываетс . Поэтому при изменении режима работы экономичность установки отклон етс  от оптимальной.Devices are known for automatically controlling a turbo drive for a circulating pump of a steam generation plant, comprising a condensate temperature controller with a pilot valve and a regulating valve of the turbo drive. However, in such devices, the pump capacity is determined only by the steam load of the condenser, and the change in temperature of the cooling water is not taken into account. Therefore, when the operating mode is changed, the efficiency of the installation deviates from the optimal one.

Цель изобретени  - повышение экономичности в щироком диапазоне режимов. Дл  достижени  этого к задатчику подключен корректор по температуре охлаждающей воды.The purpose of the invention is to increase the economy in a wide range of modes. To achieve this, a corrector for the cooling water temperature is connected to the setting device.

На чертеже приведена принципиальна  схема устройства. Охлаждающа  вода в конденсатор 1 подаетс  циркул ционным насосом 2 с турбоприводом 3, а конденсат из конденсатора / откачиваетс  конденсатным насосом 4.The drawing is a schematic diagram of the device. The cooling water to the condenser 1 is supplied by a circulation pump 2 with a turbo drive 3, and the condensate from the condenser / is pumped out by a condensate pump 4.

Производительность циркул ционного насоса 2 измен етс  перестановкой регулирующего клапана 5 турбопривода под воздействием регул тора 6 температуры конденсата, получающего сигналы от задатчика 7 и датчика 8 температуры конденсата. Тем самым производительность циркул ционного насоса согласовываетс  с паровой нагрузкой конденсатора .The capacity of the circulation pump 2 is changed by interchanging the control valve 5 of the turbo drive under the influence of the condensate temperature controller 6, which receives signals from the setpoint 7 and the condensate temperature sensor 8. Thus, the capacity of the circulation pump is matched to the steam load of the condenser.

Дл  учета изменени  температуры охлаждающей воды к задатчику 7 подключен корректор Я измер ющий температуру охлаждающей воды и соответственно мен ющий уставку задатчика 7.In order to take into account the change in the temperature of the cooling water, an equalizer I measuring the temperature of the cooling water and accordingly changing the setting value of the setting device 7 is connected to the setting device 7.
