汽轮机推力瓦烧毁的原因分析

Causes Analysis of Thrust Pads Burn-out of a Turbine

偏置支承的可倾瓦推力轴承其推力瓦块与汽轮机转子推力盘的相对旋转方向只能是单向的。因此要注意瓦块的安装方向，错装或混装都会造成烧瓦的严重事故。

Relative rotary direction can only be one-way between thrust peds in offset wupporting sloping pads thrust bearing and a rotor thrust plate of a turbine. There- fore, attention must be paid on mounting direction. Misfit or staggering mounting would re- sult in serious accidents of pads burn-out.
