Pressurized turbine expander
Thread Content
In low-temperature star-type booster turbine expanders, it is necessary to measure the operating clearance. What is the purpose of measuring this value? I need an expert to help answer this.
It is necessary to maintain the clearance between the impeller and the volute; the size of this clearance affects heat leakage and sealing performance
It is mainly to ensure the proper operation of the thrust bearing; if it is too small, the bearing surfaces may burn out
