Analysis of Fault Causes of Mechanical Seal of Ammonia Distillation Unit Ammonia Pump
According to the PMC-50*5 ammonia distillation tower feed pump mechanical seal operation fault statistics,ammonia pump is mainly non-drive end mechanical seal operation cycle is short,the general operation cycle is 15-20 days,mechanical seal is no pressure double end surface balance mechanical seal,the cause of the pump mechanical seal damage,the main reason is the mechanical seal moving ring,static ring overheating.Combined with the mechanical seal fault analysis and treatment method of PMC-50*5 ammonia distillation tower feed pump,it has a certain reference significance for the maintenance,repair and transformation of similar multi-stage pump mechanical seal in the whole plant.
