Description

кольцевом диске приводит к выравниванию давлени  в камере 8 над выступом и, следовательно , к возникновению вторичного течени , которое резко повышает гидравлическое сопротивление камер уплотнени , что ведет к снижению протечки среды по сравнению с известной конструкцией уплотнени  при прочих равных услови х па 15-30%.an annular disk leads to equalization of pressure in chamber 8 above the protrusion and, consequently, to the emergence of a secondary flow, which dramatically increases the hydraulic resistance of the seal chambers, which leads to a decrease in leakage of the medium compared to the known seal design with other things being equal pa 15-30 .

Осевые и радиальные размеры предлагаемого уплотнени  остаютс  неизменнььми.The axial and radial dimensions of the proposed seal remain unchanged.
