Изобретение касаетс  средств автоматизации судовых паровых турбин.The invention relates to automation of ship steam turbines.

Известны способы регулировани  и защиты паровой турбины с нромнерегревом путем управлени  расходом пара при изменении скорости вращени  ротора. При этом расходом пара в часть турбины после нромперегрева управл ют регулирующими и стопорными клапанами на входе в эту часть турбины .Methods are known for regulating and protecting a steam turbine with a nroming overheat by controlling the steam flow rate when the rotor speed changes. In this case, the steam flow rate to the part of the turbine after the nrompereheating is controlled by regulating and locking valves at the entrance to this part of the turbine.

Это св зано с дросселированием потока пара, в том числе н при посто нных нагрузках , что снижает экономичность способа.This is due to the throttling of the steam flow, including n at constant loads, which reduces the efficiency of the method.

Целью изобретени   вл етс  повышение экономичности способа.The aim of the invention is to increase the efficiency of the method.

По предложенному способу расходом пара в часть турбины после промперегрева управл ют открытием сброса пара в конденсатор при повышении скорости вращени  сверх определенного уровн , а при аварийном повышении скорости вращени  одновременно воздействуют на сброс пара в конденсатор и на срыв вакуума. Это позвол ет отказатьс  от регулирующих и стопорных клананов на линии после промперегрева.According to the proposed method, the steam flow rate to a part of the turbine after reheating is controlled by opening the steam release to the condenser when the rotation speed increases above a certain level, and if the rotation speed increases abnormally, it simultaneously affects the steam discharge to the condenser and the breakdown of vacuum. This allows refusal of regulating and locking clans on the line after reheat.

На чертеже приведена схема реализации предложенного способа.The drawing shows the implementation of the proposed method.

Пар из пароперегревател  / котла 2 через стопорный клапан 3, подключенный к системе 4 защиты, и регулирующий клапан 5 системы 6 регулировани  поступает в часть 7 высокого давлени  турбины и далее в промперегрев 8. Далее пар направл етс  непосредственно в часть 9 низкого давлени  турбины н в конденсатор 10.The steam from the superheater / boiler 2 through the stop valve 3 connected to the protection system 4 and the control valve 5 of the control system 6 enters the high pressure section 7 of the turbine and then the reheat section 8. The steam is then sent directly to the low pressure section 9 of the turbine capacitor 10.

При нормальных режимах нагрузку турбины определ ет открытие регулирующего клапана 5. При повышении скорости вращени  сверх определенного уровн  по снгналу системы 6 регулнрованн  открываетс  сбросной кланан 11 с клапаном 12 впрыска охлаждающей воды на лннии сброса пара в конденсатор 10, при срабатывании системы 6 защиты одновременно подаютс  сигналы на открытиеUnder normal conditions, the turbine load is determined by the opening of the control valve 5. When the rotational speed rises above a certain level, the discharge clan 11 with the cooling water injection valve 12 on the steam discharge port to the condenser 10 opens at a time when the system 6 is activated. to open

сбросного клапана И н на открытие клапана 13 срыва вакуума.waste valve And the opening of the valve 13 breakdown of the vacuum.

Предмет изобретени Subject invention

Снособ регулировани  и защиты судовой паровой турбины с промнерегревом путем управлени  расходом пара при изменении скорости вращени  ротора, отличающийс  тем, что, с целью повышени  экономичности, расходом пара в часть турбнны после промперег .1ева управл ют открытием сброса пара в конденсатор при повышении скорости вращени  сверх определенного уровн , а при аварийном новыше1нп1 скорости вращени  одновременно воздействуют на сброс нара в конденсатор и на срыв вакуума.The method of regulation and protection of the ship steam turbine with overheating by controlling the steam flow when the rotor speed changes, characterized in that, in order to improve efficiency, the steam flow to the turbine part after the industrial flow. a certain level, and in case of an emergency increase, the rotational speeds simultaneously affect the dumping of the capacitor and the breakdown of the vacuum.
