Author: DEAR AST

Before starting the liquid oxygen pump, the following preparations shall be made: blow off the residual water or oxygen with normal temperature dry gas for 10-20 minutes; Short term power supply, check whether the rotation direction of the motor is correct, and reverse rotation will reduce the flow and head of the pump; Fully precool the pump, and turn the pump to check whether it can rotate flexibly; During startup, gradually open the inlet valve of the liquid oxygen pump and open the steam vent valve until the liquid oxygen is discharged.

The manufacturing of air separation equipment is a typical non standardized manufacturing industry. It is characterized by completely customized product design, huge difference in product specifications, simple process and complex process, large and heavy raw materials. Because of the above characteristics, the manufacturing of air separation equipment is still mainly manual in the world. With the concept of intelligent manufacturing of DEAR air separation plant deeply rooted in the hearts of people, the intelligent transformation of air separation plant has brought challenges and opportunities to the air separation plant industry and intelligent manufacturing industry. It can be said that if the intelligent problem of air separation manufacturing can be successfully solved, it will have an important reference significance for the technological progress of flexible manufacturing.
