俄制210 MW汽轮机高压加热器疏水管振动原因

漳泽发电厂二期工程安装4台俄制210MW汽轮机组，每台机组配备有3台高压加热器，投产以来，高压加热器疏水管在运行中频繁发生振动导致泄漏，最终不得已将其退出备用，从而使锅炉入口给水温度大大降低，严重地影响到机组的运行安全性和经济性。从系统的运行、设备的检修等几个方面对高压加热器疏水管振动原因进行分析，提出了消除振动的预防和处理措施，在实践中取得良好的效果。

HP Heater Drainer Vibrating Cause of Soviet-made 210 MW Turbine

Since it was put into production, Zhangze power engneering 4 turbine-sets, each one equiped with 3 sets of HP heater, its drainer frequently occur vibration leading to leakage . at last it had to quit auxliary operating largely decrease boiler entrance feedwater temperature. and serious influence safty and economic operation . it analyse causes of HP heater drainer from system operating and overhaul of equipments. put forwords prevention of vibration eliminating and treatment measure. and get good effects in practice .
