在某制氧厂3200Nm3/h制氧机改造工程中,将原两台3200Nm3/h制氧机改为4500Nm3/h制氧机,主要包括分馏塔系统、空压机系统、氧压机系统、空冷水冷系统、分子筛系统等改造。分二期实施,一期投产后,再施工第二期,其中分馏塔、空压机、氧压机设备基础施工十分关键。现根据施工过程中发生的一些情况,谈一谈空压机、氧压机设备基础改造施工应注意的问题。1.±0.000相当于绝对标高复核、确认
In an oxygen plant 3200Nm3 / h oxygen generator renovation project, the original two 3200Nm3 / h oxygen generator to 4500Nm3 / h oxygen generator, including the fractionation tower system, air compressor system, oxygen compressor system, Air-cooled water cooling system, molecular sieve system transformation. Divided into two phases, a production, and then the second phase of construction, including fractionation tower, air compressor, oxygen compressor equipment, basic construction is very crucial. Is based on the construction process in some cases, talk about air compressor, oxygen compressor equipment, basic construction of the transformation should pay attention to the problem. 1. ± 0.000 Equivalent absolute height check, confirm
