Description
(54) УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ОТКЛОНЕНИЯ РОТОРА ОТ ОСИ ТУРБСМАШИНЫ(54) DEVICE FOR THE CONTROL OF THE DEVELOPMENT OF THE ROTOR FROM THE AXIS OF THE TURBS MACHINE
Изобретение относитс к теплоэнергетике и может быть использовано дл предупреждени -аварий, от задевани ротора при пуске и эксплуатации турбомашин .The invention relates to a power system and can be used to prevent an accident, from touching the rotor during start-up and operation of turbomachines.
Известны устройства дл контрол отклонени ротора от оси, содержа1цие первичные преобразователи, установленные вблизи ротора и подключенные к измерител м 1. Эти устройства имеют весьма сложную схему и .вместе с тем не обеспечивают высокой .точности контрол максимального .отклонени ....Devices are known for monitoring the rotor deviation from the axis, containing primary transducers installed near the rotor and connected to gauges 1. These devices have a very complex circuit and, nevertheless, do not provide high accuracy in controlling maximum deviation ....
Наиболее близким к изобретению вл етс устройство дл .контрол отклонени ротора от оси турбомашины , содержащее первичные преобразователи , установленные вблизи .ро-. тора и подключенные через усилители и измерители амплитуд к входам сумматора, выход которого соединен с сигнализатором и индикатором 2,Closest to the invention is a device for controlling the deviation of the rotor from the axis of the turbomachine, containing primary transducers installed close to the .ro. torus and connected via amplifiers and amplitude meters to the inputs of the adder, the output of which is connected to the alarm device and indicator 2,
Недостатком известного устройстт на вл етс его несколько понижен-. на точность контрол максимального отклонени ... .A disadvantage of the known device is its somewhat lower-. on the accuracy control of the maximum deviation ....
Цель изобретени - повышение точности контрол максимального откло- . нени .The purpose of the invention is to improve the accuracy of control of maximum deviation. nothing
Цель достигаетс тем, что в устройство введены два квадратора и блок извлечени корн , каждый из Гизмбрнтелей амплитуд .выполнен.в виде двух пиковых детекторов, блока сравнени и двух аналоговых ключей, между измерител ми амплитуд и входами сумматора включены :квадраторыг. а выходсумматора соединен с си гн ал и затором The goal is achieved by introducing two quadrants and a root extraction unit, each of the amplitudes of the amplitudes. and the output of the adder is connected to the signal and the jam
10 и индикаторомчерез блок извлечени корн .10 and an indicator through the root extraction unit.
На чертеже показана схема устройства .The drawing shows a diagram of the device.
Первичные преобразователи 1 и 2 Primary converters 1 and 2
15 установлены вблизи ротора 3 турбомашины в одной радисшьной плоскости на взаимно .перпендикул рных ос х и подключены через усилители 4 .и 5 к измерител м и 7 амплитуд. Каж20 дый .из этих измерителей выполнен . . (показано выполнение только .измерител 7) в виде двух пиковых .детекторов 8 и 9, блока 10 сравнени и двух аналоговых ключей 11 и 12. Вы25 ходы измерителей 6 и 7 амплитуды подсоединены соответственно через квадраторм 13 и 14 к сумматору 15, выход KOflfoporo в свою очередь св зан с блоком 16 извлечени корн . К блоку 16 подключен индикатор 17 непосредст3015 are installed near the rotor of the 3 turbomachine in one radius plane on mutually perpendicular axes and are connected via amplifiers 4 and 5 to the meters and 7 amplitudes. Each of these gauges is made. . (only measurement meter 7 is shown) in the form of two peak detectors 8 and 9, comparison unit 10 and two analog switches 11 and 12. The outputs 25 of the amplitude meters 6 and 7 are connected respectively via quad 13 and 14 to the adder 15 the turn is connected to the root extraction unit 16. Indicator 17 is connected to block 16 directly
