Description
под действием центробежных сил отбрасываетс к периферии камер. Это приводит к интенсивному перемешиванию двухфазного потока, его дроблению и турбулизации, что снижает протечки пара через уплотнение. Количество охлаждающей воды должно составл ть от количества протекающего пара.under the action of centrifugal forces, it is thrown to the periphery of the chambers. This leads to intensive mixing of the two-phase flow, its fragmentation and turbulence, which reduces the leakage of steam through the seal. The amount of cooling water should be based on the amount of steam flowing.
.Наибольший эффект достигаетс при следующих параметрах:The greatest effect is achieved with the following parameters:
Рассто ние канавок друг от друга /(2-3)Я, ширина канавок 6 (2-3)5, глубина канавок С(1-2)5, где 5 - зазор в уилотнении, Н - высота выступов.The distance of the grooves from each other is / (2-3) I, the width of the grooves 6 (2-3) 5, the depth of the grooves C (1-2) 5, where 5 is the clearance in elevation, H is the height of the projections.
Предложенное уплотнение позвол ет существеино уменьшить протечки среды (до 30%), что благопри тно сказываетс на экономичности турбомашины.The proposed seal allows to reduce the leakage of the medium (up to 30%), which favorably affects the efficiency of the turbomachine.
