| Abstract: | The main cylinder seal structure of hydraulic press was introduced which was combinated by rectangle sealing,guide rings and wear rings.A dynamic leakage calculation model of sealing components was established and the estimation formula was given.The structure composition and sealing principle of the rectangle sealing were analyzed,as well as the influence of its distribution in the piston seal on seal performance.The results have reference significance for hydraulic seal design. |
