| Abstract: | In order to solve the problems of the cylinder deformation,moving to one side of cylinder,jam etc on the old units,the complete and reasonable countermeasures for adjusting clearance of steam gland seal are put forward.The safety and economic benefits brought out by adjusting the clearance are computed, based on which the suggestion to adopt a new type steam gland structure is proposed to solve the safety, economic of the units, and can be used widely for maintenance of the units. |
