Shanghai Wensha Precision Mechanical Element MFG Co., Ltd

Wide range of machinery, can be divided into several different aspects of a variety of categories, such as: according to the functions can be divided into mechanical power, material handling machinery, grinding machinery; by service industry can be divided into agricultural machinery, mining machinery, textile machinery other; works can be divided into heat by mechanical, fluid mechanical, bionic machinery.

In addition, the machinery in its research, development, design, manufacture, use and other processes to go through several stages of the work of a different nature. According to these various stages, mechanical engineering but also dovetail into each other with several sub-systems, such as mechanical research, mechanical design, machine, machinery use and maintenance.

Divided according to different aspects of these various branches of the system of cross-cutting and overlapping, so that the mechanical engineering may be divided into hundreds of branches. For example, by function of power machinery, it points according to the principle of thermal mechanical, fluid machinery, turbomachinery, reciprocating machinery, steam-powered machinery, nuclear power plants, internal combustion engines, gas turbines, as well as by industry center of power station equipment industrial power plants, railway locomotives, ships marine engineering, automotive engineering and others have complex cross-cutting and overlapping relationships. Marine turbine power machinery is also the thermal mechanical, fluid mechanical and turbo machinery, it belongs to the marine power plant, steam power plant, may also belong to the nuclear power plant and so on.

Analysis of this complex relationship, the most reasonable of mechanical engineering sub-systems, have some knowledge of the meaning, but not much practical value.
