    摘要： A purge apparatus is provided. The purge apparatus is capable of preventing air from being entrained when a submersible pump is moved into a pump column, and capable of warming the submersible pump when the submersible pump is removed from the pump column to thereby prevent component of the air from being liquefied, thus preventing the liquefied gas from being emitted in the atmosphere. The purge apparatus includes a hermetic purge container (1) configured to accommodate the submersible pump (2) therein; a vacuum line (37) coupled to the hermetic purge container (1) and coupled to a vacuum source (39); a purge-gas supply line (38) coupled to the hermetic purge container (1) and coupled to a purge-gas supply source (40B); and a purge-gas supply valve (35) mounted to the purge-gas supply line (38).

    摘要： A cover (200) for a liquid reservoir (100) is provided. The liquid reservoir (100) is adapted to house a liquid pump (300) having an associated liquid pump control unit (310) therein. The cover (200) has a first part (202). The cover is characterized in that the cover (200) further includes a second part (204). The first part (202) is adapted to mount the second part (204). The second part (204) further defines a recess (210) adapted to at least partly house the liquid pump control unit (310) therein. Further, the second part (204) defines at least one opening (216) such that the at least one opening (216) allows electrically accessing the liquid pump (300) therethrough.
