현재 소방장비에 적용되어지는 소방펌프를 살펴보면 원심펌프가 주류를 이루고 있으며 폼 약제 이송 장치와 같은 특수한 장비에 용적형펌프가 일부 사용되고 있다. 또한 국내 소방펌프의 형식승인 및 검정기술기준 또한 원심펌프 위주로 되어 있어 원심펌프 이외의 펌프를 소방장비에 적용하기에는 현실적으로 많은 어려움이 있는 실정이다. 따라서 본 연구는 고압으로 대유량 방수가 가능하도록 개발된 회전용적형펌프의 방수성능을 기존의 원심펌프와 비교 테스트하고 그 결과를 분석하여 회전용적형펌프의 소방장비에 적용 가능성을 제시하고자 한다.

In this study, tests were conducted to establish a fire engine of relay waterproof and utilization in order to maintain the pressure in a situation that require high-pressure water-resistant such as a high-rise building fire, etc. As a result of test on the change of a relay waterproof pressure, the measurement result with the hydrant intake of a fire engine opened has reduced approximately 20 % compared to the measurement result with the hydrant intake closed. Similar efficiency showed in the test result that change the pressure of 2 fire engines respectively to use them more efficiently at a fire fighting activity site. A fire engine operation and utilization is proposed based on this study result in order to cope effectively with a fire site requiring high-pressure stream in a high-rise building fire, etc. by using a fire engine held at present because there is no fire pump with high-pressure stream ability arranged at the fire station and there is no regulation on high-pressure fire-fighting pumps in a type approval and verification technology criterion for a fire engine.

오늘날 급속한 산업사회 및 환경변화로 인하여 불특정 다수인들이 생활하는 공간들이 고층화 및 대형화가 가속되면서 여러 가지 문제점들이 나타나고 있으며, 그중 특히 소방안전에 있어서 현실을 만족하지 못하는 부분이 적지 않다. 이러한 문제점들을 보완하기 위하여 소방장비에 적용되어지는 소방펌프의 문제점들을 보완하고 이를 적극 활용하여 새로운 소화체계의 개선과 장비 운영의 효율화를 기하고자 하며, 앞서 연구 개발된 회전용적형 펌프에 기동성과 다양성을 접목하여 기존의 소방시스템에 적극 활용하고자 한다. 그간 법적인 문제로 인하여 원심펌프 이외의 펌프를 소방장비에 적용하기에는 현실적으로 적지 않은 어려움이 있었다. 전술한 문제점을 보완하여 기동성과 접근성을 도출하여 초기화재에 보다 효과적으로 대응하는 소방장비의 접목 가능성을 제시하고자 한다.

Purpose: This study is based on the detailed inspection data for the last 6 years of fire-fighting high ladder vehicles, fire-fighting inflected ladder vehicles, fire-fighting chemical vehicles and fire-fighting pump vehicles used in front-line fire departments. The purpose is to contribute to the technological development of fire-fighting vehicles by grasping the implementation status of each city and province, the rate of defects, and the occurrence of defects by year. Method: The implementation status by city and province, defect incidence rate, and defect occurrences by year were analyzed. Result: From 2012 to 2017, when the average of 230 or more overhaul vehicles was requested, the results of each city/province show slight fluctuations, but the number of defects gradually decreased due to the old fire-fighting vehicle replacement project and the response of fire vehicle manufacturers. Conclusion: In the case of fire-fighting ladders, the incidence rate of defects was found to be in the order of elevator device, electric device, ladder device, and pneumatic supply device. And in the case of the fire fighting ladder, it was confirmed that the incidence of defects appeared in the order of the refractive ladder, hydraulic cylinder, hydraulic oil, and pneumatic supply device. In the case of fire-fighting chemical vehicles, it was confirmed that defects occurred in the powder fire extinguishing device, fire pump, vacuum pump, and pneumatic supply device.

This paper analyzed firefighting officers' use situations such as the use time, maximum working pressure, hose diameter, etc. of fire pumps at fire sites and carried out various performance tests by pressures, hose diameters and quantities of fire pumps based on its results because the waterproof performance criterion for a fire pump installed in a fire engine is different from the operation situations at the site and is not clearly prescribed. As a result of site survey, the site uses a higher pressure than the standard water discharge pressure (0.85 MPa) or the high-pressure water discharge pressure (1.4 MPa) prescribed by the approval Standard of the fire pump performance on fire truck. In addition, as a result of pump performance test, the discharged water flow rate, water discharge pressure, etc. was measured to be very different from the currently prescribed the approval standard depending on the hose diameter and firefighting nozzle, so the result of this study proposes a new standard.

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.

소방펌프는 소방설비 시스템에서 가장 중요한 설비임에도 불구하고 그동안 펌프의 기동 정지를 압력탱크(챔버)방식으로만 할 수 밖에 없었기 때문에 셋팅 및 유지관리 등에 많은 어려움이 있었으나 전자식기동용압력스위치를 이용한 새로운 펌프기동장치가 도입이 되었기에 이에 대한 특징과 장단점 등을 분석, 검토하였다.
