classification of machinery

There are many types of machinery, which can be divided into various categories according to several different aspects.

For example, according to the function, it can be divided into power machinery, material handling machinery, crushing machinery, etc.; according to the service industry, it can be divided into agricultural machinery, mining machinery, textile machinery, packaging machinery, etc.; according to the working principle, it can be divided into thermal machinery, fluid machinery, Bionic machinery, etc.

The main products of machinery industry include the following 12 categories:

Agricultural machinery: tractors, planters, harvesting machinery, etc.;

Heavy mining machinery: metallurgical machinery, mining machinery, hoisting machinery, loading and unloading machinery, industrial and mining vehicles, cement equipment, etc.;

Construction machinery: forklifts, shovel and transport machinery, compaction machinery, concrete machinery, etc.;

General petrochemical machinery: petroleum drilling machinery, oil refining machinery, chemical machinery, pumps, fans, valves, gas compressors, refrigeration and air conditioning machinery, paper making machinery, printing machinery, plastic processing machinery, pharmaceutical machinery, etc.;

Electrical machinery: power generation machinery, transformers, high and low voltage switches, wires and cables, batteries, electric welding machines, household appliances, etc.;

Machine tools: metal cutting machine tools, forging machinery, foundry machinery, woodworking machinery, etc.;

Cars: trucks, highway buses, cars, modified cars, motorcycles, etc.;

Instrumentation: automation instrumentation, electrical instrumentation, optical instrument, composition analyzer, automobile instrumentation, electrical equipment, audio-visual equipment, camera, etc.;

Basic machinery: bearings, hydraulic parts, seals, powder metallurgy products, standard fasteners, industrial chains, gears, molds, etc.;

Packaging machinery: packaging machines, cartoners, conveyors, etc.;

Environmental protection machinery: water pollution control equipment, air pollution control equipment, solid waste treatment equipment, etc.;

Mining machinery: rock splitting machine, capping machine, etc.

Construction machinery refers to the general term for construction machinery used in engineering construction. It is widely used in construction, water conservancy, electric power, roads, mines, ports, national defense and other engineering fields.

There are many types of construction machinery, which are mainly divided into:

Excavating machinery: such as single bucket excavators (which can be divided into crawler excavators and wheeled excavators), multi-bucket excavators (which can be divided into bucket wheel excavators and chain bucket excavators), multi-bucket trenching excavators Machine (also can be divided into bucket wheel trencher and bucket chain trencher), rolling excavator, milling excavator, tunnel boring machine (including shield trench machine, tunnel boring machine), etc.;

Shoveling and transporting machinery: such as bulldozers (which can be further divided into tire bulldozers and crawler bulldozers), scrapers (which can be further divided into crawler self-propelled scrapers, tire self-propelled scrapers and drag scrapers), Loaders (also can be divided into tire loaders and crawler loaders), graders (also can be divided into self-propelled graders and drag graders), transport vehicles (also can be divided into single-axle transport vehicles and double-axle Towing trucks), flatbed trucks and dump trucks, etc.;

Lifting machinery: such as tower cranes, self-propelled cranes, mast cranes, grab cranes, etc.;

Compaction machinery: such as tire rollers, smooth wheel rollers, single foot rollers, vibratory rollers, tamping machines, tamping machines, etc.;

Piling machinery: such as drilling machines, diesel pile drivers, vibratory pile drivers, pile drivers, etc.;

Reinforced concrete machinery: such as concrete mixer, concrete mixing plant, concrete mixing plant, concrete pump, concrete mixing truck, concrete sprayer, concrete vibrator, steel processing machinery, etc.;

Road machinery: such as leveling machine, ballast cleaning machine, etc.;

Rock drilling machinery: such as rock drilling rigs, pneumatic rock drills, electric rock drills, internal combustion rock drills and down-the-hole rock drills, etc.;

Other construction machinery: such as bridge erector, pneumatic tools (pneumatic tools), etc.
