摘要
硝酸三柱泵密封结构设计不合理,造成密封易失效,严重地影响和制约了直硝装置浓硝酸的生产。通过对其密封函结构进行改进,解决了三柱泵密封泄漏引起的环境污染和检修频繁问题,保证了直硝装置生产的正常进行。
The nitric acid three plunger pump seal box structural design is unreasonable, creates seals easily to expire, seriously affected and restricted the straight niter instrallation production. Through makes the improvement to its seal box structure, has solved the environmental pollution and the overhaul frequent question which three Plunger seal divulges causes, had guaranteed the straight niter installation production normally carries on.
