Fubction of the housing:

Bearing capacity:The shell resists the external load through the uniformly distributed middle stress,which can make full use of the material strength,so as to have greater bearing capacity.

Wide application:Shell has a wide range of app;ications in hydraulic engineering,machinery manufacturing and the other fileds.

Safeguard function:Shell plays a fundamental safeguard function in the development of science and technology,and is the foundation of many equipment and structures.
