PET熔体增压泵故障探讨

Discussion on the failure of PET melt booster pump

分析PET装置熔体增压泵卡阻,泵体端盖渗漏熔体的原因及使用过程中存在问题。提出了齿轮泵的改造方案。此次增压泵故障处理经验,值得在聚酯全行业推广。

The reasons for the melt booster pump jamming and pump cover melt leakage in PET plant and the exist- ing problems during the application process were analyzed. The modification scheme of gear pump was put forward. This booster pump fault treatment experience is worth promoting in PET industry.
