Abstract

Positive displacement pumps with high pressure and water capacity are used large fires in various high-rise buildings. This study provides information for a performance approval standard of fire pumps for fire trucks based on centrifugal pump standards enacted in 2012. An experiment was conducted with a positive displacement pump for three levels of performance from the approval standard (V-1, 2, and 3). The efficiency of the pump was included in the reference, which requires the approval of 65% performance, the same as a centrifugal pump. The water pressure is between 1.5 and 2.5 MPa, and the required flow rate was established as at least $0.31m^3/min$ and up to $3.0m^3/min$. A relief valve was added to adjust the shut-off pressure due to the structural characteristics of the positive displacement pump. A strainer was also installed to prevent damage to the inside of the pump due to foreign matter. However, the strainer includes a difference from the positive displacement pump to operate without a vacuum pump and the centrifugal pump. This is due to the additional approval standard portion of the positive displacement pump, which is expected to be selected for more variety of fire-fighting equipment and proactive responses to fire suppression in a high-rise buildings and large fires. In conclusion, this approval standard was enacted in January 2016.

본 연구는 2012년도에 제정된 원심펌프 기준에 바탕을 둔 소방자동차용 소방펌프의 성능 인정 기준에 각종 초고층 건물의 화재 및 대형화재에 대비하기 위한 고압 및 대용량의 방수 능력을 가진 용적형 펌프의 인정기준 추가에 관한 내용이다. 용적형 펌프의 실험을 바탕으로 V-1, 2, 3급의 3가지에 대한 성능에 대하여 인정기준을 제정하였으며 펌프의 효율은 원심펌프형과 동일한 65% 이상의 성능을 요구하는 인정기준이 포함 되었다. 방수압력은 1.5 MPa~2.5MPa 사이의 값을 유량은 최소 $0.31m^3/min$에서 최대 $3.0m^3/min$의 방수량의 성능을 요구하는 것으로 제정되었다. 또한, 구조적으로 체절압력을 조절해야하는 용적형 펌프 특성상 릴리이프 밸브에 대한 부분이 추가되었으며 이물질로 인한 펌프 내부의 파손을 방지하기 위한 스트레이너 설치 및 진공펌프 없이 작동하는 용적형 펌프와 원심펌프와의 차이점을 포함하고 있다. 이와같은 용적형 펌프의 인정기준 부분 추가로 인하여 초고층 빌딩 및 대형화재에서의 화재진압에 있어서 보다 다양한 화재 진압용 소방 장비의 선택과 능동적인 대응을 할 수 있을 것으로 기대되며, 이와같은 인정기준은 2016년 1월 제정되었다.
