Problems solved by technology

[0002] Blast furnace hydraulic mud cannon is a necessary front-of-furnace equipment in the metallurgical industry. During the repair of the cylinder of the mud cannon and mud cannon in the blast furnace process of the ironworks, the repair quality of the mud cannon will directly affect the production of the blast furnace. In the past The conventional sealing structure is used in the repair work, resulting in a little oil leakage after the repaired mud pumping cylinder has been used for a period of time, including external seepage or internal seepage, which will cause certain damage to the mud blasting work of the mud gun impact, reduce work efficiency, and the life cycle of the mud blowing assembly will also be shortened

Abstract

The invention belongs to the technical field of mechanical design, and discloses a blast furnace gun mud ramming assembly oil cylinder sealing transformation structure which comprises a cylinder body, a piston, a cylinder rod and a cylinder cover, the piston, the cylinder rod and the cylinder cover are arranged on the cylinder body, and a step seal and a V-shaped combined seal are sequentially arranged between the cylinder cover and the cylinder rod and face the piston from outside to inside. According to the oil cylinder sealing transformation structure, the problem of poor sealing performance in the prior art is solved, the sealing performance of the mud gun mud ramming oil cylinder is improved, and therefore the service life of the mud ramming oil cylinder is prolonged. The invention further provides a blast furnace gun mud ramming assembly oil cylinder sealing transformation method.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and in particular relates to a structure and a method for reforming the seal of an oil cylinder of a blast furnace mud gun mud blasting assembly. Background technique [0002] The blast furnace hydraulic mud gun is the necessary equipment in front of the furnace in the metallurgical industry. In the repair work of the mud gun mud gun mud gun in the blast furnace process of the ironworks, the repair quality of the mud gun assembly will directly affect the blast furnace production. The repair work adopts a conventional sealing structure, which leads to a little oil seepage after a period of use of the repaired mud-dripping cylinder, including extravasation or internal seepage, which will cause certain damage to the mud-cracking work. Influence, reduce work efficiency, and the life cycle of the mud beater assembly will also be shortened. SUMMARY OF THE INVENTION [0003] In view of this...
