D300离心式煤气鼓风机密封系统的改造

Reconstruction of Sealing System of D300 Centrifugal Gas Blower

针对D300离心式煤气鼓风机密封系统泄漏煤气的问题,通过对原单一迷宫密封系统改造为氮气组合式密封系统,改变传统的密封方式,控制煤气泄漏在标准以内,确保了安全生产。

There was gas leakage problem in the sealing system of D300 centrifugal gas blower. For this reason, the original single labyrinth sealing system was reconstructed to the nitrogen combined sealing system. Through the reconstruction, the gas leakage was controlled within the standard range and safe production was guaranteed .
