REASONS FOR OIL LEAKING FROM THE OIL SEAL OF CO_2 COMPRESSOR TURBINE AND THE COUNTERMEASURES

In Dongting Nitrogenous Fertilizer Plant,the oil seals both back and forth of the drive turbine of urea CO2 compressor leaked oil.In the light of years of practical observation and experience,the author suggested a schedule of modifying the structures of the seals in the turbine and put it into effect.It was proved by the practice that after the modification the oil leaking from the oil seals was controlled under an assumed value, hence the modification achieved an ideal effect.
