【Abstract】 The article mainly analyzes the mechanisms that casused the packing seepage,while improvement measures the methods of low pressure opposite diretion of absorb、high pressure opposite diretion of rush down、various kind of type packing collocation are proposed. The result of application shows: its production of operation period would be increased by over 400%,and the rate of seepage would be reduced by over 80%.更多还原
