According to an embodiment of the present invention, a system for processing a liquefied natural gas comprises: a cylinder; a piston; a sealing member; and a heat source member. The cylinder allows a fuel to be introduced and discharged. The piston performs a reciprocal movement inside the cylinder to pressurize the fuel. The sealing member is positioned on the circumferential surface of the piston to seal the piston and the cylinder. The heat source member supplies heat to the sealing member. According to the present invention, when a diesel mode is changed to a gas mode, the system of processing the liquefied natural gas and a high pressure pump drives a standby mode, thereby achieving a cool down and preventing damage to the sealing member of the high pressure pump converted into an operation standby state in the standby mode. Therefore, leakage of the fuel, which is caused by damage to the sealing member, can be blocked, and a stable drive can be performed.

    본 발명의 일 실시예에 따른 액화가스 처리 시스템은, 연료가 유출입되는 실린더; 연료를 가압하도록 상기 실린더 내부를 왕복운동하는 피스톤; 상기 피스톤과 상기 실린더를 씰하도록, 상기 피스톤의 둘레면에 마련되는 씰링부재; 및 상기 씰링부재로 열을 공급하는 열원부재를 포함하는 것을 특징으로 한다. 본 발명에 따른 고압 펌프 및 액화가스 처리 시스템은, 디젤모드에서 가스모드로 변경시 스탠바이 모드를 구동하여 쿨다운을 이루면서도 스탠바이 모드시 작동 대기 상태로 변환된 고압 펌프의 씰링부재가 파손되는 것을 방지하여 씰링부재의 파손으로 인한 연료의 누수를 차단하고 안정적인 구동을 수행할 수 있다.
