Abstract: 종래에 전기 생산 방식은 대부분을 원자력 수력 화력 발전 등으로 비교적 규모가 큰 기업에서 전기를 생산하여 각 가정이나 기업체로 전기를 공급 하고 있다 
     본 고안은 필요한 수압 만큼 주 물 탱크를 수직으로 세워서 자연 수압이 발생케 하여 그 수압의 힘으로 토출구를 통한 물이 회전체를 돌게하고 회전체가 돌면서 회전체에 연결되어 있는 발전기를 돌려서 전기를 생산하고 그 회전체를 돌린 물은 보조 물 탱크에 고이고 주 물 탱크의 수압으로 보조 물 탱크의 물을 무동력 정량펌프가 흡입하여 수격펌프를 통하여 물을 주 물 탱크 위로 끌어 올려 주고 또한 발전기 용량이3kw라면 2.7kw는 가정으로 0.3kw는 전기펌프를 통해서 정량펌프와 같이 보조 물탱크의 물을 주 물 탱크로 물을 끌어 올리게 한다 이 동작을 반복 하면서 영구적으로 전기를 생산하는 무동력 물 순환식 발전 장치 입니다 
     토출구에서 나오는 물의량과 무동력 정량펌프와 전기펌프가 흡입하는 물의량은 비례 한다 
     파이프 길이를 수직으로 50메타를 세우면 파이프 밑쪽의 수압은 5kg의 압력이 발생함 
     본 고안은 파이프를 수직으로 세워서 물의 압력을 이용하여 발전을 하여 각 가정이나 기업에서 무동력으로 자가 발전을 할수 있도록 고안된 무동력 물 순환식 발전장치입니다 
     (참고문헌) 
     (수압) 
     물 속의 한 점에서는 전후·좌우·상하의 모든 방향에서 같은 세기의 힘이 미친다. 
     그 크기는 물의 깊이에 따라 달라지며, 대기압을 고려하지 않으면, 깊이가 10cm 증가할 때마다 10g중의 비율로 수압이 늘어난다. 수심 10m인 곳에서는1kg중의 힘을 받게 되는 것이다 
     (수격펌프) 
     다른 곳에서 동력을 받지 않고 흐르는 물을 간헐적으로 막아, 그 수격작용을 이용해서 높은 곳으로양수(場水)하는 펌프 
     작은 낙차로 흐르는 물을 간헐적으로 막아 이때 발생하는 수격압력을 이용하여 높은 곳으로 물을 퍼 올리는 펌프. 실제로 사용되는 것은 구동수량(驅動水量)이 시간당 1∼40m 3 , 낙차 1∼30m, 양정(場程) 약 300m이다. 양수능력에 비해 대형이기 때문에 그다지 많이 사용되지 않았으나, 외부로부터의 동력을 필요로 하지 않고 운전비가 적게 들어 근래 에너지 절약 펌프로서 주목받고 있다. 〔그림〕과 같이 밸브 V 1  이 열리면 저수조 속의 물이 관 P, V 1  을 통해 대기 중으로 방출된다. 방출된 물은 서서히 가속되어 유속이 어떤 값이 되면 흐름에 의한 힘으로 V 1  이 급격히 닫힌다. 이때 수격이 발생하여 고압이 생겨 밸브 V 2  가 열리고 물이 양수조까지 양수된다. 수격에 의한 압력파(壓力波)는 P 속을 몇 차례 왕복하는 사이에 감쇄되어 T  속의 압력이 내려가면 V 2  가 닫히고 V 1  이 열려 물이 다시 대기 중으로 방출되는데, 이러한 동작이 반복된다. 
     수격펌프 원리도 
     
       
     
     (무동력 정량펌프) 
     무동력 펌프 개요 
     무동력 펌프는 외부적인 에너지 공급 없이 작동합니다. 
     이송 매개물(물)은 기계적인 시스템에 의해 움직이는 dosing head안의 doding 피스톤이 아래위로 작동할 때 drive를 통해서 흐른다. dosing피스톤의 진동수는 이송 매개물(물)의 양에 비례한다. 
     dosing 피스톤이 위로 작동하면 dosing head안에는 진공이 생성된다. 
     그 진공은 흡입파이프를 통해서 매체(체인윤활제)를 빨아 드리게 된다. 
     anti-siphon 밸브는 무동력 펌프의 line 상류와 하류 사이에서 진공이 생성될 때 자동적으로 열리게 된다. (siphon effect) 
     이것은 투입매개체(체인윤활제)의 제어되지 않는 회류를 방지한다.용수 공급라인과 직접 연결하여, 전기 공급없이 자체 물의 힘만을 동력원으로 사용합니다
