Analysis of the reasons for turbine tripping
Thread Content
Analysis of the reasons for turbine tripping: In the case of Hangzhou Zhongneng’s extraction-type condensing turbines, high extraction pressure and reduced vacuum occur during operation, which leads to turbine tripping. I would appreciate it if experienced users on this forum could advise me on what inspections should be carried out and what measures need to be taken. Operating parameters (based on practical requirements): Main shaft intake/extraction/air supply/exhaust; Power in kW, speed in r/min, flow rate in kg/h, pressure in MPa(A), temperature in °C. Rated values: 3.9440; Normal values: 37791220522500; 3.743095000.42500.012. Minimum values: 3.6, 420
I’m from Hangzhong Neng. For troubleshooting general tripping faults, one must first analyze whether the trip is caused by mechanical reasons or electrical issues. Then check them one by one. Vacuum bottoms can also cause chain picking issues. If it is due to vacuum problems, it is necessary to first check whether the exhaust pumps (those that use water or steam) are working properly; the methods for checking vary in this case. There are adjustable pumping and non-adjustable pumping methods, and they are different from each other. Please explain in more detail
