What is the purpose of the two pipelines connecting the condensing turbine to the steam trap expansion tank?
Thread Content
The water condensed in the primary vacuum condenser is sent to the hydrophobic expansion tank through a water seal. At the start of operation, there is no water in the condenser; so how can water be poured into the U-tube? What is the purpose of this U-shaped water seal? The other stream is discharged to the drain through a steam trap! What is its use?
The primary drain of the extraction pump is equipped with a U-tube, resulting in a lower pressure difference, while the secondary drain has a valve assembly, giving a higher pressure difference. Additionally, no water needs to be filled into the U-tube
Okay, thank you. So what is the function of a first-grade hydrophobic U-shaped water seal?
