Introduce the shortcoming of CL-1-75 liquid argon pump and analyze the reason about it.

The paper discusses how to improve the quality of liquid argon in order to produce more liquid argon from three aspects such as liquid argon analysis system,flowing into liquid argon storage and its quality control based on production condition of Gas Company.

Variety of argon amount in the argon transport system in an oxygen plant resulted in part of liquid argon going into the carbon steel pipelines at the back of the air temperature-type vaporizer and also resulted in frost crack of the carbon steel pipelines.

Shock temperature of liquid argon has been measured under the shock pressure up to 33GPa by employing the two-stage light gas gun.
