Title: Способ перевозки вязких нефтепродуктов и железнодорожная цистерна для его реализации
Inventor: MOISEEV VLADIMIR IVANOVICH
IPC: B65D88/00
Filed: 2018-04-28
Granted: 2019-03-14
Abstract: Способ перевозки вязких нефтепродуктов, например мазутов, включает их налив в цистерну при температуре, превышающей плюс 250°С, и отличается тем, что нефтепродукт охлаждается в нижней части ее котла до температуры плюс 100°С, в верхней же части котла его температура сохраняется прежней. При этом плотность нефтепродукта в нижней части котла становится большей, чем в верхней его части на 17%. Горячий нефтепродукт перевозится, находясь в гидродинамически устойчивом, стратифицированном, состоянии, в отсутствие естественной конвекции, что резко снижает скорость его охлаждения. В высоковязкое состояние переходит лишь малая часть нефтепродукта, вблизи стенок котла цистерны, общей массой около шести тонн. При этом до шестидесяти тонн нефтепродукта сохраняет высокую температуру и текучесть. Размыв застывшего слоя при выгрузке нефтепродукта требует меньшего времени и меньших затрат тепловой энергии. Железнодорожная цистерна для перевозки вязких нефтепродуктов отличается тем, что имеет внутри парообогревательного кожуха зигзагообразную по форме перегородку, отделяющую стенку котла цистерны от наружной стенки парообогревательного кожуха, а кожух при наливе в цистерну горячего нефтепродукта заполняется водой. При температуре нефтепродукта, превышающей плюс 250°С, в кожухе возникают процессы испарения и конденсации воды, характерные для термосифона. Они вызывают охлаждение нижней части котла цистерны с переводом наливаемого нефтепродукта в стратифицированное состояние. В нижней части котла устанавливается короткая переходная труба, к которой крепится сливной патрубок. Внутри переходной трубы помещается сосуд с теплопоглощающим материалом, обеспечивающий охлаждение наливаемого нефтепродукта до температуры плюс 60°С. Охлажденный нефтепродукт в переходной трубе изолирует резиновое уплотнительное кольцо сливного патрубка от горячего нефтепродукта в котле цистерны. 2 н. и 1 з.п. ф-лы, 2 ил., 2 табл.

Определяют в этом спектре наличие гармонических составляющих фиктивной обмотки ротора на нижних боковых частотах, определяемых по выражению:где- нижняя боковая частота гармоники фиктивной обмотки ротора ν-го порядка Гц,t - текущее время при пуске, 0≤t≤T, с,Т - продолжительность пуска асинхронного двигателя, с;ƒ- частота сети, Гц,s(t) - скольжение ротора;p - число пар полюсов двигателя;ν - порядок гармоники. При наличии указанных гармонических составляющих формируют сигнал о наличии обрыва стержня обмотки ротора. Технический результат: повышение достоверности результатов контроля при расширении функциональных возможностей. 6 ил., 1 табл.
