Description
coca трубопроводом 12 такого диаметра, который обеспечивает подачу масла в количестве , достаточном дл проворачивани в обратном направлении рабочих колес насоса турбнны с малой скоростью. Дл поддержани перепада давлени масла на уплотнени х вала ротора в допустимых пределах при работе аварийного насоса 7 он соединен через редукционный клапан 13 со сливным коллектором /.coca pipe 12 of such a diameter that provides sufficient oil for turning the turbine pump impellers in a reverse direction at a low speed. In order to maintain the differential pressure of the oil on the rotor shaft seals within acceptable limits when the emergency pump 7 is operating, it is connected through a pressure reducing valve 13 to a drain manifold.
Предложенна система работает следующим образом.The proposed system works as follows.
При отказе источников маслоснабжени 2 автоматический клапан W открывает подачу газа на газовую турбину 8, котора сначала останавливаетс , а затем быстро разворачиваетс до номинальной скорости вместе с аварийным насосом. Под действием давлени масла аварийного насоса 7 обратный клапан 9 открываетс и масло поступает на уплотнени . Избыток масла сбрасываетс в сливпой коллектор через редукционный клапан 13. При падении давлени газа в генераторе скорость врагцени турбины 8, а следовательно, и аварийного насоса 7 снижаетс , давление .масла падает и при достижении определенного значени редукционный клапан 13 перекрываетс . Все масло поступает на уплотнени .In the event of failure of the oil supply sources 2, the automatic valve W opens the gas supply to the gas turbine 8, which first stops and then quickly turns to the nominal speed along with the emergency pump. Under the pressure of the oil of the emergency pump 7, the check valve 9 opens and the oil enters the seals. Excess oil is discharged into the drain manifold through the reduction valve 13. When the gas pressure in the generator drops, the speed of the enemy turbines 8 and, consequently, of the emergency pump 7 decreases, the oil pressure drops and when a certain value is reached, the reduction valve 13 closes. All the oil enters the seals.
Газова турбина вращаетс до полного выхода газа из генератора. После этого уплотнени снабжаютс маслом из демпферного бака. В случае восставовлеии работоспособности источника маслоснабжени лиии выброса газа в атмосферу перекрываетс автоматическим клапаном, газова Турбина останавливаетс , аварийный насос переводитс в режим резерва.The gas turbine rotates until the gas completely leaves the generator. After this, the seals are supplied with oil from the damper tank. In the event that the source of the oil supply to the atmosphere is restored to operability, the gas is blocked by an automatic valve, the gas turbine is stopped, the emergency pump is switched to standby mode.
Примеиение аварийного насоса в системе маслоснабжени уплотнений вала турбогенератора , приводимого во вращение газовой турбиной, работающей на газе, выбрасываемом в атмосферу из генератора при отказе всех источников маслосна1бжени уплотнений вала, повышает надежность системы маслоснабжени и эксплуатации тур., богенератора путем исключени аварийныхThe application of an emergency pump in the oil supply system of the shaft seals of a turbogenerator driven by a gas turbine powered by a gas emitted into the atmosphere from the generator when all sources of oil seals fail, increasing the reliability of the oil supply system and operation of the turbogenerator by eliminating the emergency oil

При этом сокращаютс материальные затраты на ремонт турбогенератора и сох1ран етс бесперебойное обеспечение электроэнергией потребител-ей .failure due to oil supply to the shaft seals. At the same time, the material costs for the repair of the turbogenerator are reduced and uninterrupted power supply to the consumer is maintained.
