There are many kinds of machinery, which can be divided into various categories according to several different aspects. For example, mechanical gears can be divided into power machinery, material handling machinery, crushing machinery, etc. according to functions; industries can be divided into agricultural machinery, mining machinery, Textile machinery, packaging machinery, etc.; according to the working principle can be divided into thermal machinery, fluid machinery, bionic machinery. The main products of China's machinery industry include the following 12 categories: Agricultural machinery: tractors, seeders, harvesting machinery, etc.; Heavy mining machinery: metallurgical machinery, mining machinery, lifting machinery, loading and unloading machinery, industrial and mining vehicles, cement equipment, etc.; Construction machinery: forklifts, earthmoving machinery, compaction machinery, concrete machinery, etc.; General petrochemical machinery: oil drilling and mining machinery, oil refining machinery, chemical machinery, pumps, fans, valves, gas compressors, refrigeration and air conditioning machinery, paper machinery, printing machinery, plastic Processing Machinery, pharmaceutical machinery, etc.; Electrical machinery: power generation machinery, transformers, high and low voltage switches, wire and cable, batteries, electric welding machines, household appliances, etc.; Machine tools: metal cutting machine tools, forging machines, foundry machinery, woodworking machinery, etc.; Automobiles: trucks, road buses, cars, modified cars, motorcycles, etc.; Instrumentation: automated instrumentation, electrical instrumentation, optical instruments, component analyzers, Mechanical gears (Fig. 6) automotive instrumentation, electrical equipment, audio-visual equipment, cameras, etc.; Basic machinery: bearings, hydraulic parts, seals, powder metallurgy products, standard fasteners, industrial chains, gears, molds, etc.; Packaging machinery: packaging machine, packing machine, conveyor, etc.; Environmental protection machinery: water pollution prevention equipment, air pollution prevention equipment, solid waste treatment equipment, etc.; Mining machinery: rock splitting machine, top stone machine, etc. Construction machinery refers to the general term for construction machinery used in engineering construction.
