Description

DONGSUH Blower Seal Kit (5CDL, 9CDL BLOWER OVERHAUL SEAL KIT) is a blower maintenance kit for power generation plant and it maximized the efficiency of the oil seal (Contact Seal) by changing the structure to Labyrinth Seal (Non-contact Seal) in cooperation with KOSPO in 2014.

Construction Of Blower Seal Kit

This non-contact type circular sealing body prevents the leakage that is caused by pressure difference between each steps. For reduction of leakage amount through Labyrinth Seal, it is necessary to have the seal geometry increase the flow resistance. The Labyrinth Seal is consisted of rotor having step and stator having many tooth. The steam is throttled when it passes through the contraction while the pressure decreases in the expansion repeating on and on, so the leakage volume is decreased since it is equal to the pressure of Labyrinth outlet.
