聚酯切片生产中冷却水的自动供给

AUTOMATIC SUPPLY COOLING WATER IN THE PET CHIP PRODUCTION

本文主要介绍了生产聚酯切片时对冷却水供水系统长期满负荷工作，出现较大的能耗，回水有外溢和空打等现象进行改进，达到自动控制和节能效果．

In PET chip production, the cooling water supply system always works in full load and long time. Its energy consumed is rather large. The recycle water often overflows and the pump runs id1e. Such behavior has been improved away by an automatic supply system of cooling water. So a resu1t of automatic control and energy economization is achieved.
