Explanation of the Hangzhou Steam Turbine model EHNKS50/63
Thread Content
Does anyone know what each letter and digit represents in the Hangzhou Steam Turbine’s model number EHNKS50/63?
Reply to 1# zsr3011: For EHNKS50/63 steam turbines: E – exhaust ventilation, H – high-pressure intake, N – atmospheric-pressure intake, K – condensing type; HN– indicates the presence of both high-pressure and atmospheric-pressure intake sections. 50 – inner radius of the cylinder (cm), 63 – diameter at the root of the last stage of the rotor (cm). Your turbine is of the high-pressure exhaust and condensing type
Sincere thanks for the reply regarding the second floor!
E represents extraction steam； H represents high-pressure steam inlet ； N corresponds to the extraction steam pressure; extraction at atmospheric pressure ； K corresponds to exhaust steam; it is used in condensing and extraction-type units, with high-pressure steam intake, medium-pressure exhaust steam, and exhaust steam condensation. As mentioned by the ally on the 2nd floor, 50/63 represent the cylinder bore diameter (diameter) and the diameter of the final impeller, respectively, with the unit being cm
As a supplementary note, S stands for dual output shafts.
