Reasons for bending of turbine electromechanical main shaft UNITROL 1020 Communication module ABB
Steam turbine, also known as steam turbine engine, is a rotating steam power device. High-temperature and high-pressure steam passes through the fixed nozzle and becomes an accelerated air stream, which is sprayed onto the blade to make the rotor with blade row rotate and work externally. Steam turbine is the main equipment of modern thermal power plant, and also used in metallurgical industry, chemical industry, and ship power plant.
The structural parts of steam turbine are composed of rotating parts and stationary parts. The rotor includes the main shaft, impeller, moving blade and coupling. The stator includes steam inlet part, cylinder, diaphragm and stator cascade, steam seal and bearing, etc. What causes the bending of the main shaft of the steam turbine?
Reasons for bending of turbine electromechanical main shaft
1. Poor thermal insulation of cylinder. If the thermal insulation of the cylinder is poor, the upper and lower cylinders will have a large temperature difference during the startup and shutdown of the steam turbine. Generally, the temperature of the upper cylinder is higher than the temperature of the lower cylinder, which makes the upper cylinder expand higher than the lower cylinder, and the upper cylinder arch. Hengxinglong small editor suggests that this phenomenon is commonly known as “cat arch back”. When the arch back occurs, the amplitude clearance of the lower cylinder decreases, resulting in dynamic and static friction.
2. Water or cold steam enters the cylinder.
3. Permanent bending caused by thermal bending of rotor.
4. Due to strong vibration during operation, it causes dynamic and static friction and heat generated after friction. Due to the violent vibration friction, the temperature of the friction part is very high, resulting in the reduction of the yield strength of the material. The excessive thermal stress causes the thermal deformation of the shaft, and causes the convex bending of the axial friction side, which further aggravates the temperature rise, resulting in the increased bending of the shaft.
5. Improper adjustment of shaft seal during installation or maintenance and insufficient clearance of steam seal.
The above is the reason why the main shaft of the steam turbine is bent. I hope it can help you. Hengxinglong motorized spindle – combines the advantages of compact structure, light weight, small inertia, small vibration, low noise, fast response, and many other advantages, such as high speed, high power, and so on. It is also more and more widely used in the field of CNC machine tools. We undertake the design and manufacture of various high-speed electric spindles/spindle motors/high-speed motors, as well as the repair and maintenance of various high-speed electric spindles/spindle motors/high-speed motors/spindle heads at home and abroad.
