Tank wagon pump for liquid nitrogen was made in Switzerland CRYOMEC Company and used in air separation unit of project of methanol made by coal in the Chemical Engineering Subcompany, Hebi CoalElectricity Stock Company Ltd. Author has introduced the main property parameters and structure for pump of tank wagon of liquid nitrogen with a capacity of 600 000 t/a;has analyzed the leakage reason for mechanical seal of tank wagon of liquid nitrogen;has briefly described the relevant technical reformation measure and the effect. Result indicates that the operation of tank wagon pump for liquid nitrogen is stable;the effect of mechanical seal is also good after technical reformation.
