1. Not only the pump itself to keep cold, suction pump pipeline must also be cold measures to prevent in operation from the outside world to absorb heat, the liquid vaporization, affecting the performance of the pump;
2. Cryogenic pump assembly parts are not allowed to be stained with water and grease, parts must be washed with a solvent, dry and then assembly;
3. In the case of explosive gas, the motor should use vertical explosion-proof motor;
4. Pumps and piping, if not, moisture and air, when the access to low temperature liquid will freeze, so before the pump put into operation to clean up, and then with a dry nitrogen scavenge, drive away the pump Within the moisture and air, and pre-cooling;
5. Cryogenic pump inlet and suction lines should have exhaust device so that the pump before operation or operation can be ruled out in a timely manner to accumulate the gas to ensure the reliable operation of the cryogenic pump;
6. Cryogenic transport can also be used cryogenic shielding pump.
