译文：
1.不仅泵本身要保冷，泵的吸入管线也必须有保冷措施，以防在运行中从外界吸入热量，使液体汽化，影响泵的性能；
2.低温泵装配零件严禁沾上水会和油脂，零件必须用溶剂洗涤干净，干燥后再进行装配；
3.在有爆炸性气体场合，电动机宜选用立式防爆电动机；
4.泵及管路内如有没、水分和空气等，当通入低温液体时会结冰，因此在泵投入运行之前需清洗赶干净，然后用干燥的氮气等进行扫气，赶走泵内的水分和空气，并进行预冷；
5.低温泵的吸入口和吸入管路应有排气装置，使泵在运行前或运行中能及时排除逐渐积存的气体，保证低温泵可靠地工作；
6.低温输送也可选用低温屏蔽泵。

原文：
1. Not only the pump itself to cold, the pump suction pipe must also be cold-measures to prevent inhalation in the operation of the heat from the outside world, so that vaporization of the liquid affect the pump performance;
2. Cryogenic pump assembly parts and the non-stained water, grease, spare parts must be solvent washed clean, dried and then assembled;
3. Explosive gas occasions, the motor should use vertical explosion-proof motor;
4. Pump and piping, if not within, water and air, etc., when the cryogenic liquid will pass into the ice, so need to wash pump in operation before the drive clean, then use dry nitrogen to sweep gas, off pump within the water and air, and conduct pre-cooling;
5. Cryogenic pump suction mouth and inhaled the exhaust pipe should be installed so that pump operation can be run either before or promptly remove the gradual accumulation of gas, cryogenic pumps to ensure reliable work;
6. Cryogenic transfer pumps can also use low-temperature shield
