Description

농약 분무기용 양방향 피스톤 복열식 고효율 펌프장치Bidirectional Piston Recuperator High Efficiency Pump Unit for Pesticide Sprayer
본 발명은 농약 분무시 피스톤에 의해 펌핑동작이 양방향 복열로 이루어져 효율이 극대화되는 것은 물론 제작이 쉽고 조립이 용이할 뿐 아니라 보다 저렴한 비용으로 고성능의 펌핑동작이 가능한 농약 분무기용 양방향 피스톤 복열식 고효율 펌프장치에 관한 것이다.According to the present invention, the pumping operation by the piston when spraying pesticides is maximized efficiency, as well as easy to manufacture and easy to assemble, as well as a high-performance pumping operation for a pesticide sprayer for two-way piston recuperator type high efficiency pump at a lower cost Relates to a device.
통상 농약 분무기에 설치되는 통상의 펌프는 아주 다양한 모델들이 개발되어 있지만, 대부분 구조가 복잡하고 펌핑 효율에 한계를 갖는 동시에 고장이 잦거나 제작비용이 비싸서 경제성이 떨어지는 문제점이 있을 뿐만 아니라, 필요이상으로 큰 소비전력과 대용량의 모터, 그리고 펌핑 실린더 및 피스톤이 사용되고 있어서 필요 이상으로 상당한 중량이거나 체적 및 에너지소비가 컸던 문제점이 있다.Conventional pumps usually installed in agrochemical sprayers have been developed with a wide variety of models, but most of them are complicated in structure and limited in pumping efficiency, and often have a problem of low cost due to frequent breakdowns or high manufacturing costs. Large power consumption, large-capacity motors, pumping cylinders and pistons are being used, which causes problems such as significant weight or volume and energy consumption.
일간에서는 모터 및 피스톤을 포함한 실린더의 크기 등을 소형화한 펌핑장치가 출시된 사례가 있기는 하지만, 펌핑 및 분사압력이 약하여 작물이 있는 먼 곳까지 긴 호스로 농약을 분사시킬 때 분사되는 압력이 약하여 효과적인 분사가 어려웠던 문제점이 있었다.Although there have been cases where a pumping device with a smaller cylinder size including a motor and a piston has been released on a daily basis, the pumping and spraying pressures are so weak that the spraying pressure when spraying pesticides with a long hose to a far place with crops is weak. There was a problem that effective spraying was difficult.
