Turbine manufacturers teach you how to perform turbine maintenance.
Due to the complex structure and special operating environment of steam turbines, they are highly susceptible to various adverse factors, leading to mechanical failures such as bearing bush burning and journal wear, which severely disrupt their normal operation. Here, the steam turbine manufacturer will guide you on how to perform steam turbine maintenance, analyze the root causes of these failures, and implement effective preventive measures—actions that undoubtedly hold great practical significance for ensuring the smooth operation of power plants. I. Analysis of the Causes of Journal Wear Faults in Steam Turbine Maintenance: 1. Overloading: When equipment operates under excessive load, it can cause the bearings to overheat and burn out. 2. Low lubricating oil pressure or

Working Principle of Steam Turbines
The operating principle of a steam turbine involves the flow of steam, the generation of forces acting on the blades, the formation of losses, and methods for adapting the turbine to changes in external load. According to how the energy contained in the steam is converted into mechanical work within each stage of the turbine, turbine stages can be classified into three types: impulse stages, reaction stages, and velocity stages. The operating principle of an impulse stage: In the nozzle, the steam expands, with its pressure dropping from p0 at the inlet to p1 at the outlet. As the cross-sectional area of the nozzle passage gradually decreases, the velocity of the steam within the nozzle steadily increases. The energy contained in the steam is transformed into kinetic energy of the steam flow, and upon exiting the nozzle, the absolute velocity of the steam...

Common Issues in Turbine Installation
During the installation of steam turbines, turbine leakage and cylinder deformation are among the most common equipment problems. The tightness of the cylinder joint surface directly affects the safe and economical operation of the unit. Therefore, inspecting and lapping the cylinder joint surfaces to ensure their tightness is an essential part of cylinder maintenance. In addressing steam leakage at the joint surface, it is crucial to carefully analyze the underlying causes. Depending on the degree of deformation and the size of the gap, various methods can be employed in combination to achieve the required tightness of the joint surface. Causes of Cylinder Leakage

As the application scope of steam turbines continues to expand, so does the attention paid to them by industry professionals. However, after a certain period of use, steam turbines inevitably encounter various types of failures, making turbine maintenance an increasingly important issue. Steam Turbine Repair and Fault-Handling Procedure To accurately diagnose faults in steam turbines, it’s essential to start with the specific characteristics exhibited by the fault itself. By identifying the unique features inherent to the fault, we can analyze and summarize the types of failures that manifest based on these characteristics. The following are the current methods for diagnosing steam turbine faults:
