What are the reasons why the rated power and pressure of the low-temperature liquid pump in the air separation equipment cannot be reached, and how to deal with them?

Answer: Kaifeng deer air separation has the first complete intelligent production line of fractionator recognized by the industry in China (put into construction in 2019) Positioning: full automatic production line of cold box/fractionator cylinder, three-dimensional warehouse AGV、 Robot welding, visual blanking, mes+"Deere smart brain", continuous plate cutting, rounding, welding, film washing, and pipe Island assembly, not piecemeal robot transformation. Key points: it is the first recognized intelligent production line of air separation equipment in the air separation circle, especially for the aluminum alloy tower of air separation.

Answer:It can be done, and there is just a public 7500nm ³/h (80% o ɑ) VPSA benchmark project: Jiangyin Huaxi iron making VPSA project Parameters: 7500nm ³/h, 80% oxygen purity, vpsa-7500 specification, smelting oxygen enriched condition, BOT mode, supporting their own blue bank intelligent operation and maintenance system Background: This is the VPSA project publicly announced by Deere air separation. Previously, Deere's main business was cryogenic air separation, and VPSA is a new product line. Key point differentiation (very important) 1. the 7500 is a single set of VPSA adsorption tower group, not multiple sets in parallel; Purity 80%, blast furnace/iron making oxygen enriched standard working condition 2. Deere does not take VPSA as its main business, and cryogenic is its strength; VPSA molecular sieve is purchased 3. capability boundary: at present, VPSA performance is publicly disclosed, and there is no case of a larger single set (≥ 10000) VPSA being publicly put into operatio
