China Drying Newsletter As of January 1, 2013, the turbine rotor of the urea plant CO2 compressor in Daqing Petrochemical Plant has been running smoothly for 625 days, marking the success of the research on the turbine rotor end-stage and sub-last stage blade breaking project of the CO2 compressor. The transformed blade of this project is the first in China.
According to reports, the steam turbine is a complete set of equipment imported from Italy in the early stages of construction. Since the commissioning of the steam turbine, there have been many accidental blade breakages of the last stage and second stage, which severely restricted the long-term operation of the urea plant. It has been learned that similar accidents often occur in other chemical fertilizer companies of the same type, and blade fracture has become a common problem for chemical fertilizer companies. In this regard, the company set up a research team specifically to analyze the causes of blade fracture from multiple angles, and put forward a reform program and implemented it.
After two years of operation, the operating parameters and spectrum of the modified urea plant CO2 compressor steam turbine are in full compliance with the technical agreement requirements. It is expected that the modified rotor can be operated normally for 5 to 10 years, and annual economic losses of 4.65 million yuan due to rotor blade fracture can be recovered.
Laser engraving is a surface treatment process of electroplating processing, printing in processed products or patterns such as light, through the laser beam to the material surface chemical and physical changes and engraved traces, or burned part of the material through the light, show the required etching of graphics and text. Jin Yuankang company currently has a high-power laser engraving machine more than and 10, 3D laser engraving machine 4, with the intelligent robot arm to conduct a full range of products, multi angle processing, to meet customer needs, system characteristics:
