Description

лей 12, то при изменении режима работы уплотнени  зазор корректируетс  изменением расхода дросселей. Работа запорного участка уплотнени  L сводитс  к подводу запорного газа к пазам б и отводу из них утечек.Lei 12, then when the sealing mode changes, the clearance is corrected by changing the flow rate of the chokes. The operation of the seal sealing area L is reduced to supplying the closing gas to the grooves b and withdrawing leaks from them.
