Modification of compressor belt drive system

Thread Content

In recent years, due to the updating of societal standards for safe production in the petroleum and chemical industries, more new requirements have been imposed on equipment that has been in use for some time. One of these requirements concerns the driving methods for power equipment in these industries, and detailed explanations are provided regarding this aspect. Clause 5.7.7 of the \"Code for Fire Protection Design of Petrochemical Enterprises (2018 Edition)\” (GB 50160-2008) stipulates that belt drives shall not be used for combustible gas compressors, liquefied hydrocarbons, and combustible liquid pumps within chemical processing areas. In the 1980s and 1990s, China purchased a large number of compressors driven by belts. Considering factors such as the safety and reliability of the equipment as well as its long-term operation, it has become an urgent task to change the way in which compressors are connected to their drive units to direct connection or connection via couplings. Scope of modification: motor, flywheel, coupling, bottom skid foundation, etc. Challenge: The equipment is often old, lacking reliable after-sales support and follow-up services ； Connection components such as flywheel couplings need to be selected and manufactured based on rigorous calculations by specialized manufacturers, whereas users often lack the necessary expertise.
