The critical speed issue of Hangzhou Motor Vehicles
Thread Content
We are dealing with steam turbines and compressors produced by Hangzhou Steam Turbine Factory. Compressors have a critical speed, but why don’t the data sheets provided by this factory contain any information regarding this critical speed? All the fields related to it are blank. Please give some advice
If the rotor is a rigid rotor, the critical speed is higher than the operating speed, but it should also be recorded.
What is your rotational speed? During normal operation, it should be below 0.7n1 (where n1 refers to the first critical speed); in that case, there will be no issue with sudden acceleration. Moreover, there is usually a high-speed interlock in place. You can consult the turbine manufacturer again to get more detailed information~~
What is your rotational speed? It’s usually available; the units we use certainly have it. You’d better ask, otherwise it could be a problem during startup
