Main reason for frequent failure on mechanical seal of low boiling column bottoms in the production of methane chloride is due to impurity entry and airproof structure, unreasonable material.
It has good airproof, and the frame material is used with high strength cast iron, SKF bearing. These ensure the motor can reliably run under the tough condition.
具有良好的密封型，外壳采用高强度铸铁材料，轴承选用SKF轴承，确保电机在恶劣的环境下可靠运行。

The new designed valve has metal-metal plane hard airproof structure, using durably grinding material near the flowing road to improve the airproof surface usage life-span.
