Finite element analysis for scroll pressure for tension-coiling process;

The calculation of the scroll pressure is the premise of the calculation of the coiler strength and compensator pushing force, and is directly related with the coiling quality.

Structure design of the automatical compensation and radial compaction soft stuffing seal;

Analysis of the radial pressure distribution functions of piston ring;

Experimental method of calculating radial pressure in barrel of screw press

Through analyzing the acting force on filling seal of the valve shaft,the change trend of filling radial pressure along valve shaft axis was educed and the main factors that influence upon filling feal of the valve shaft were analyzed.
