The paper investigates the reasons for the crack and invalidation of the 432mm blades and analyses the blades vibration characteristics , the components of the saline dirtiness on the blades and the crack sections of the blades for the 51-50-1 model turbine in Baotou No. 2 Power Plant. Finally , the paper gives the reasons for the blades crack and the suggestions for improvement of the blades.

针对我国在役汽轮机中的432mm叶片的失效情况,调查了叶片的断裂、失效的原因;结合包头第二热电厂51-50-1型机组,对432叶片的振动特性、叶片的盐垢成分及叶片的断口进行了分析,最后得出导致叶片发生断裂的主要原因是振动。提出了改进叶片的建议。

No.5 steam turbine of Baotou No.2 Cogeneration Power Plant was 51 50 1 type steam turbine made by Harbin Steam Turbine Works in 1969, rated at 50 MW, with main steam pressure of 8.9 MPa, main steam temperature of 500 ℃, back pressure of 0 005 MPa and rated rpm of 3 000. This steam turbine was put into operation in August 1970 and had accumulatively operated 190 000 hours as of the end of 1995, being an aged unit.

No.5 steam turbine of Baotou No.2 Cogeneration Power Plant was 51 50 1 type steam turbine made by Harbin Steam Turbine Works in 1969, rated at 50 MW, with main steam pressure of 8.9 MPa, main steam temperature of 500 ℃, back pressure of 0 005 MPa and rated rpm of 3 000. This steam turbine was put into operation in August 1970 and had accumulatively operated 190 000 hours as of the end of 1995, being an aged unit. Currently this unit can still operate normally, no distinct defects are detected out in the rotor. The thermal stress and life expenditure during start up and shutdown and the residual life of this steam turbine are studied and evaluated on the basis of operation records.

包头第二热电厂的5号机组是哈尔滨汽轮机厂于1969年生产的51501型汽轮机,额定功率50MW,新蒸汽压力89MPa,新蒸汽温度500℃,背压0005MPa,额定转速3000r/min。该机组于1970年8月投入运行,至1995年末已累计运行19万h,属老化机组。但目前机组仍能正常运行,转子金属探伤也无明显缺陷。文章根据机组的运行记录,对其起停热应力、寿命损耗和剩余寿命进行了研究和评估。

According to the successively expanding heat supply areas of Baotou secondary thermal power plant,the reliability of heat supply becomes the cardinal task of thermal power plant.The paper proposes a solving method that is changing the 5# unit into low vacuun heat supply,and using it as the spare unit for 3#,4#unit,in order to improve the heat supply reliability.

随着包头第二热电厂供热面积的不断扩大 ,提高供热可靠性成为供热期间电厂的头等大事。将 5 #机改为低真空供热 ,并作为 3#、4 #机低真空供热的备用机组 ,大大增强了供热可靠性
