What Industry Category Does the Compressor Crankshaft Belong?

Industry ownership of compressor crankshaft

compressor crankshaft is the core moving part of reciprocating compressor, which is responsible for converting the rotating motion of motor into reciprocating motion of piston. It does not belong to terminal consumer goods, but is typical.Industrial basic parts, widely used in refrigeration, air conditioning, air pressure system, petrochemical industry, automobile engine and other fields.

Analysis of major industry categories

• general machinery manufacturing industry: as the key subsystem of compressor body, crankshaft is classified into general equipment manufacturing (GB/T 4754-2017 c34)
• special equipment manufacturing industry: if it is used for refrigerating machine or natural gas booster, it will be included in the special equipment manufacturing category.
• Auto parts industry: automotive air conditioning compressor crankshaft also belongs to the supply chain link of automotive parts
• high-end equipment basic parts industry: high precision and high reliability crankshaft involves advanced manufacturing processes such as forging, heat treatment and precision machining.

From the National Bureau of Statistics “national economic industry classification”, its closest subdivision code isC3411 metal structure manufacturing(For custom forgings) orC3421 pump, Valve, compressor and similar machinery manufacturing— The latter is the most commonly used and authoritative classification basis.
