Liquid oxygen pump

How to operate cold start-up aFfter fault shutdown of air separation unit

Liquid gasification filling system consists of liquid storage tank, liquid pump and air purifier. In order to ensure the normal operation of the liquid pump, besides the reliability of the structure of the pump itself, the piping technology is also very critical. Improper piping, if it is light, it will cause "cavitation phenomenon" of the liquid pump, and the decrease of flow rate will lead to large mechanical loss of the pump; if it is serious, the filling pressure cannot be improved due to the serious gasification of the liquid in the pipe, the pump cannot work normally. Therefore, the following problems should be paid attention to when piping: 1) the base of the storage tank should be over 1m higher than the center of the liquid oxygen pump to ensure that the inlet of the pump has a higher static pressure (higher than the saturation pressure corresponding to the temperature ); 2) shorten the length of the pipeline from the storage tank to the pump inlet as much as possible to re...
