In the liquid oxygen gasification filling system, in order to ensure the normal operation of the liquid oxygen pump, In addition to the reliable structure of the pump, attention should also be paid to the piping: the foundation of the storage tank should be more than 1m higher than the center of the liquid oxygen pump; the length of the pipeline from the storage tank to the pump inlet should be shortened as far as possible, and the broken bellows and filter should be installed at the pump inlet; the insulation of the inlet pipeline should be strengthened; the air return pipeline should be installed in the pump suction chamber, and the blow out valve should be installed; the temperature compensation should be considered for the pump discharge pipe Stress.
