ZHENGZHOU YUKUN 720,000 m3/h TURBINE EXPANDERS

Turbo expanders are one of the main machine units matching for ASP. Since the 1960s,our company has been engaging in the R& D, design and manufacture of the turbo expanders. So far, there have been thousands of our expanders operating in the iron & steel, petrochemical and other industries.

In late 1980s and early 1990s, our company cooperated with Xi’an Jiaotong University for joint researching and developing the booster turbo expanders. By importing the physical database, our company has developed out the design software applicable for many fluids, in order to study the thermodynamic features and the power matching features at both ends of the turbo expanders, our company specifically set up a trial-run station to obtain a large amount of experience data, which enriched the design calculations software and improved the design accuracy greatly. In 1995, we imported a design and machining software package from NREC, USA and also imported from Boston Digital, USA a 5-axis CNC machining center specially for machining the 3-dimensioned impellers. With those advanced software, we could make the performance forecasting and optimization of the expanders and boosters; we could make the analysis on the 3-dimensioned flow field and design of the 3-dimensioned impellers. Thus, the fully automatic machining of the impellers could be realized; the design accuracy is greatly increased which fully ensured the high consistency of the designed performance and the actual operating data. The efficiency of the unit has approached or even reached to the world latest level.
