In the operation of the full low-pressure oxygen generator, if a large amount of gas in the centrifugal liquid oxygen pump gasifies and blocks the flow channel, it will cause the phenomenon of gas blockage. In case of gas blockage, the centrifugal liquid oxygen pump will not discharge liquid oxygen, the outlet pressure will not rise or fluctuate greatly, there is liquid impact sound in the pump, and even the pump body will vibrate, which will cause the centrifugal liquid oxygen pump to fail to work. However, the gas blockage of the centrifugal liquid oxygen pump will not damage the liquid oxygen pump.
DEAR air separation has the technology of vertical installation of internal parts of distillation tower. The assembly quality of the internal parts of the rectification tower directly affects the rectification effect of the equipment. Referring to the structure of the space launch vehicle, Deere process technicians designed and manufactured the lifting platform for special equipment assembly. The vertical assembly is adopted to realize the consistency between assembly and manufacturing and the operation of the tower body, ensure that the packing is assembled without hindrance, ensure the perpendicularity tolerance of the collector, distributor and the tower body, and give play to the maximum efficiency of the rectification tower. According to the assembly characteristics of tower products, the assembly quality and safety are guaranteed to the greatest extent.
