In recent years, at low temperature and high load production, the No.8 steam turbine at Fushun Petrochemical Plant has been subject to fracture for about 100 days after running the main oil pump diaphragm. Every 3 months of operation, the diaphragm must be replaced to make the external steam pressure appear. fluctuation. To this end, the plant began to improve in 2010, after repeated exploration of the transformation program, and finally proposed to change the original four corneal slices to six corneal slices, the installation gap is set to 0.2 mm of technological transformation measures. In November 2011, after the technical renovation was completed, after 105 days of high-load winter production, the diaphragm was intact. Fushun Petrochemical Thermal Power Plant Steam Turbine No. 8 steam turbine diaphragm main engine technology has recently been successful, greatly improving the reliability of equipment and production safety.
