Abstract

FIELD: compressor engineering. SUBSTANCE: if the engine goes from a low speed condition into a high-speed condition OR unit 6 generates a signal for opening the valve. When the valve is open the outlet of unit 6 is directly connected with the control unit of the valve. In according to the signal the outlet of unit 6 is connected to the control unit of the valve and outlet of unit 9 is disconnected from the control unit of the valve by the use of switch 11. . EFFECT: simplified method. 2 dwg

Предотвращение увеличения режима работы по частоте вращения ротора высокого давления (ηвд) выше максимального (заброс Δη pf,h. вд ) при открытии клапанов перепуска (КПВ) воздуха осуществляется следующим образом. Команда на закрытие клапанов формируется при увеличении режима, например, с малого газа (МГ) на максимальный (МАКС.) На режиме МГ I1 = 1, I2 = 0, I4 = 1 и блок ИЛИ формирует сигнал на открытие КПВ согласно логике его работы. КПВ открыты (IКПВ = 1), и выход блока на прямую соединен с управлением КПВ - по сигналу IКПВ = 1 выход блока соединяется с управлением КПВ и выход блока отсоединяется от управления КПВ с помощью переключателя. По мере увеличения режима I1 изменяется с 1 на 0, выполняется условие I1 = I2 = I4 = 0, и КПВ закрываются. По сигналу закрытия КПВ (IКПВ = 0) управление осуществляется через блок. Выход блока соединяется с одним из входов блока, а сигнал на открытие поступает с выхода блока, подключенному к управлению КПВ с помощью блока по сигналу IКПВ = 0. Когда ηвд уменьшится на величину Δηвд от исходной, то формируется команда на открытие КПВ. На режиме Макс. I1 = I2 = I4 = 0, КПВ закрыты, переключатель обеспечивает управление КПВ от блока. При перемещении αруд с Макс. на МГ появляется сигнал I3 = 1 и блок формирует сигнал на открытие КПВ. При этом начинается уменьшение режима, появляется сигнал I3 = 1, формируется команда на открытие КПВ, и открытие осуществится по команде блока,подключенного с помощью блока по команде IКПВ = 0.Prevention of an increase in the operating mode in terms of the rotational speed of the high pressure rotor (η in ) above the maximum (cast Δη pf, h. vd ) when opening the bypass valves (CPV) air is as follows. The valve closing command is generated when the mode is increased, for example, from small gas (MG) to maximum (MAX.) In the MG mode I 1 = 1, I 2 = 0, I 4 = 1 and the OR block generates a signal to open the CPV according to the logic his works. CPVs are open (I CPV = 1), and the output of the unit is directly connected to the CPV control - by signal I CPV = 1, the output of the unit is connected to the CPV control and the block output is disconnected from the CPV control using a switch. As the mode increases, I 1 changes from 1 to 0, the condition I 1 = I 2 = I 4 = 0 is satisfied, and the CPV closes. According to the closing signal of the CPV (I CPV = 0), control is carried out through the unit. Output unit connects to one input unit, and a signal for opening is supplied from the output unit, connected to the CPW management unit via the signal CPV I = 0. When η tm Δη reduced by the value tm from the reference, the formed command to open the CPV. In max mode I 1 = I 2 = I 4 = 0, the CPV is closed, the switch provides control of the CPV from the unit. When moving α ores with max. a signal I 3 = 1 appears on the MG and the unit generates a signal to open the CPV. At the same time, the reduction of the mode begins, the signal I 3 = 1 appears, a command to open the CPV is generated, and the opening will be carried out at the command of the unit connected using the block under the command I CPV = 0.
