Abstract
본 고안은 펌프가 가동될 때 회전차(임펠러)의 떨림을 방지해주는 임펠러웨어링과 임펠러의 조합에서 이물질이 그 틈 사이에 끼여 마모 또는 진동을 발생시켜 펌프의 효율저하 및 수명단축에 미치는 영향이 크므로 임펠러의 유입부 외주면에 커터날을 장착하여 유입되는 이물질(머리카락, 천, 와이어, 비닐)등을 효과적으로 커팅하여 펌프가 상시 적으로 안전한 상태에서 운전되도록 해준다. The present invention is a combination of impeller wear ring and impeller that prevents shaking of the rotor (impeller) when the pump is running, and foreign matter is caught between the gaps, causing wear or vibration, which greatly affects the efficiency and shortening of the pump. The cutter blade is mounted on the outer circumferential surface of the inlet of the furnace impeller to effectively cut inflow foreign materials (hair, cloth, wire, vinyl), etc., so that the pump is always operated in a safe state.
하수처리장이나 중계펌프장은 생활하수를 이송함으로 하수 속에 머리카락, 천 등의 이물질이 많이 있고 그 이물질 중 대부분의 많은 양은 회전차(임펠러) 내부로 유입되어 배출되지만 일부가 회전차(임펠러)와 임펠러웨어링 사이의 틈에 끼여 펌프의 진동과 베어링 수명단축을 초래한다.The sewage treatment plant or the relay pumping station transfers the daily sewage, so there are many foreign substances such as hair and cloth in the sewage, and most of the foreign substances flow into the rotor (impeller) and are discharged, but some of the rotor (impeller) and impeller wear ring The gap between them results in vibration of the pump and shortened bearing life.
본 고안인 커터 블레이드 임펠러를 장착하여 펌프의 안정적인 사용이 가능하므로 펌프의 수명연장에 크게 기여할 수 있다.Since the cutter blade impeller of the present invention can be installed, the pump can be used stably, which can greatly contribute to the life of the pump.
Description
본 고안은 임펠러웨어링 과 조립되는 회전차(임펠러)의 외주면에 커터날을 장착하여 임펠러와 임펠러웨어링의 마모를 방지하며, 모든 펌프에 적용하여 진동을 줄이고 그로 인한 효율증대에 따른 펌프 수명연장과 유지관리비를 절감하기 위한 고안이다. The present invention prevents abrasion of impeller and impeller wear ring by installing cutter blade on the outer circumference of impeller wear ring assembled with impeller wear ring, and applies to all pumps to reduce vibration and extend pump life by increasing efficiency It is designed to reduce the management cost.
본 고안의 착안은 펌프 고장의 요소 중 하나인 임펠러 외주면과 임펠러웨어링 틈 사이에 끼인 이물질 때문에 펌프 작동 중 그로 인한 많은 진동이 생긴다. 이 진동은 임펠러 및 임펠러웨어링 부의 마모를 발생시키고 결국 펌프의 수명을 단축시킨다.The idea of the present invention is that there is a lot of vibrations during the operation of the pump due to the foreign matter caught between the impeller outer peripheral surface and the impeller wear ring gap, which is one of the factors of the pump failure. This vibration causes wear of the impeller and the impeller wear ring and ultimately shortens the life of the pump.
본 고안은 상기에 기술된 단점을 보완하고 펌프 수명을 연장하기 위하여 임펠러의 외주면에 커터날을 장착하여 틈 사이로 유입되는 이물질을 커팅하여 줌으로 펌프의 효율향상에 큰 이점이 있다. The present invention has a great advantage to improve the efficiency of the pump by cutting the foreign matter introduced between the gap by mounting the cutter blade on the outer peripheral surface of the impeller to compensate for the above-described disadvantages and to extend the pump life.
본 고안은 임펠러웨어링과 조립되어 지는 임펠러의 틈 사이로 이물질이 끼여 펌프가 가동되는 동안 진동을 발생시키고 임펠러와 임펠러웨어링의 마모를 발생시킨다. 본 고안은 상기에 기술된 단점을 보완하고자 고안되었다.The present invention generates a vibration and pumps the impeller and the impeller wear ring while the pump is running due to foreign matters interposed between the impeller wear ring and the assembled impeller. The present invention is designed to compensate for the above described disadvantages.
본 고안은 임펠러웨어링과 조립되어지는 임펠러의 외주면에 커터 역할을 할 수 있는 형상의 홈을 파낸 모양으로 금형(목형)을 제작한 후 외주면을 가공하면 커터 블레이드 임펠러가 된다. 이때 상부로 갈수록 커터의 홈을 좁게 만들어주면 틈으로 유입되어 끼인 이물질이 임펠러의 회전에 의해서 커팅 된다. The present invention is a cutter blade impeller when the outer peripheral surface is processed after manufacturing a mold (wooden) in the shape of a groove that can serve as a cutter on the outer peripheral surface of the impeller to be assembled with the impeller wear ring. At this time, if the groove of the cutter is made narrower toward the top, foreign substances introduced into the gap are cut by the rotation of the impeller.
본 고안에 의한 커터 블레이드 임펠러는 임펠러와 임펠러웨어링 틈 사이에 끼이는 이물질을 제거하여 펌프 운전상태를 최적의 상태로 만들어준다. The cutter blade impeller according to the present invention removes foreign substances caught between the impeller and the impeller wear ring gap, thereby making the pump operating state optimal.
본 고안인 커터 블레이드 임펠러는 펌프의 수명연장에 큰 역할을 수행한다. The cutter blade impeller of the present invention plays a big role in extending the life of the pump.

도1은 본 고안에 의한 커터 블레이드 임펠러를 장착한 펌프의 전체도 이고, 커터 블레이드 임펠러와 임펠러웨어링이 조립되어진 A부를 확대하여 예시한 도2 와 커터 블레이드 임펠러의 도3 이 있다. Figure 1 is an overall view of a pump equipped with a cutter blade impeller according to the present invention, there is shown in Figure 2 and Figure 3 of the cutter blade impeller and an enlarged view of the A portion assembled with the cutter blade impeller and the impeller wear ring.
본 고안에 의한 도2 로 상세하게 설명해보면 펌프가 가동되어 물이 유입될 때, 물과 함께 다량의 이물질이 유입된다. 그 이물질 중 일부가 임펠러 커터(4)와 임펠러웨어링(6) 틈 사이로 끼이면 상부로 갈수록 좁게 만들어진 커터의 홈을 따라 이물질이 임펠러 회전에 의해서 커팅된다. Referring to Figure 2 according to the present invention in detail when the pump is operated is introduced, a large amount of foreign matter is introduced with the water. If some of the foreign matter is caught between the gap between the impeller cutter 4 and the impeller wear ring 6, the foreign material is cut by the impeller rotation along the groove of the cutter made narrower toward the top.
