Description
제 1 도는 본 고안의 분해 사시도.1 is an exploded perspective view of the present invention.
제 2 도는 본 고안의 종단면도.2 is a longitudinal sectional view of the present invention.
제 3 도는 제 1 도의 A-A'선 단면도.3 is a cross-sectional view taken along the line AA ′ of FIG. 1.
본 고안은 양수기의 와권실에서 연장되는 배출구를 서로 대각방향으로 2개 형성하고 와권실 외측에 저수실을 연설함으로서, 종래 양수기에 비하여 고양정화를 추구하면서 양수량을 증가시키고 동시에 시동시물을 주입할 필요가 없도록 한 자흡식 양수기에 관한 것이다.The present invention forms two outlets extending from the vortex chamber of the water pump in a diagonal direction to each other and addresses the storage chamber outside the vortex chamber, thereby increasing the amount of pumping while pursuing high purification compared to the conventional water pump and simultaneously injecting starting water. A self-contained water pump eliminates the need.
종래 양수기는 출력이 적어 양수량을 만족할만하게 증가시키려면 양수기의 양정이 너무 낮아지고 고양정의 효과를 얻으려고 할 때는 상대적으로 양수량이 너무 감소되었으며, 또 시동시에는 양수기내에 물을 주입하여야만 양수가 시작되는등의 결합이 있었다.Conventional water pumps are low in power output to increase satisfactorily the pumping volume of the pump is too low, and the amount of pumping water is relatively reduced when trying to obtain the effect of high pumping, and pumping starts only when water is injected into the pump at startup. There was a back bond.
본 고안은 종래 이러한 결함을 보완하면서 농촌에서 동력 경운기나 소형엔진으로 쉽게 사용할 수 있고 종래것에 비해 고양정, 다량 양수력을 가진 자흡식 양수기를 안출한 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention can be easily used as a power cultivator or a small engine in a rural area, while compensating for such deficiencies, and a self-contained pump having a high lift and a large amount of pumping power compared to the conventional one is described. same.
즉, 푸울리(1)와 회전익(2)을 동축상에 형성하여 플랜지(3)에 관삽하고 이를 기대(4)에 조립한 다음 흡입관(5)과 와권실(6)을 형성한 몸체(7)를 플랜지(3)에 조립하여서 된 통상의 것에 있어서, 와권실(6)의 내면에 두개의 배출구(8)(8')를 서로 대향토록 형성하여 토출관(9)(9')과 각각 연결시키고, 와권실(6)의 좌측과 하부가 유입공(10)과 유출공(11)으로 각각 상통되는 저수실(12)을 연설하여서 된 것이다.That is, the body (7) formed with the pulley (1) and the rotor blade (2) coaxially, inserted into the flange (3), assembled to the base (4), and then formed the suction pipe (5) and the spiral winding (6) ), The two outlets 8 and 8 'are formed on the inner surface of the spiral winding chamber 6 so as to face each other, and the discharge pipes 9 and 9', respectively. Connected, the left and the bottom of the spiral winding chamber 6 is to speak the storage chamber 12 is communicated to the inlet hole 10 and the outlet hole 11, respectively.
이와같이된 본 고안은 회전익(2)이 고속회전을 하면 흡입관(5)으로부터 공기를 빨아들인 후 용수가 흡입되어 양배출구(8)(8')를 통해 토출관(9)(9')으로 토출되는데, 종래 양수기는 처음 시동할 때 별도로 물을 주입시켜야 비로소 양수작용을 하게 되어 있으나, 본 고안은 저수실(12)에 물이 항상 저장되어 있으므로 회전익(2)이 회전하면 와권실(6) 내부가 저압상태로 되면서 저수실(12)의 유출공(11)으로부터 저장되었던 물이 유출되어 와권실(6) 내부를 채워주기 때문에 양수작용을 정상적으로 시작하게 된다.In the present invention, when the rotor blade 2 rotates at high speed, water is sucked from the suction pipe 5 and water is sucked and discharged through the discharge pipes 8 and 8 'to the discharge pipes 9 and 9'. However, the conventional water pump is to be pumped only when water is injected separately at the first start, but the present invention is because the water is always stored in the reservoir 12, the rotor blade (2) rotates inside the spiral winding chamber (6) As the low pressure state is the water stored in the outlet 11 of the reservoir 12 is discharged to fill the inside of the spiral winding (6) to start the pumping action normally.
일단 양수작용이 정상적으로 돌입하면 저수실(12)내의 공기는 배출되고 따라서 유입공(10)을 통해 주시실(12)내에 다시 물이 자동적으로 채워진다.Once the pumping operation normally enters, the air in the reservoir 12 is discharged and thus water is automatically filled again in the gaze chamber 12 through the inlet 10.
그리고, 종래 양수기를 보면 와권실의 배출구가 한개로 형성되어 있어 물이 회전익의 회전력에 의해 이론상 360°회전하여 압출되므로 토출관이 적을 때는 고양정의 효과는 있으나 회전익이 물의 압력을 많이 받으므로 압력손실이 많으며 토출관이 클 경우는 시간당 양수량은 커지나 고양정의 효과를 얻을 수 없었다.And, in the conventional pumping machine, the outlet of the spiral winding chamber is formed by one, and water is extruded by the rotational force of the rotor theoretically by 360 °. Therefore, when the discharge pipe is small, the effect of the high head is high, but the rotor blade receives a lot of pressure, so the pressure loss If the discharge tube is large, the amount of pumping per hour increases, but the effect of high head is not obtained.
그러나, 본 고안은 종래의 것과 대비하여 설명하면, 배출구가 서로 대향되게 2개로 형성되어 있기 때문에 물이 회전익에 의해 180°회전한 뒤 배출구로 배출되므로 종래 양수기보다 압력손실이 적어지므로 종래 양수기에 비하여 시간당 양수량이 증가하고 고양정의 효과도 향상되는 등의 특징을 지닌 것이다.However, when the present invention is described in comparison with the conventional one, since the outlet is formed in two opposite to each other, the water is discharged to the outlet after rotating 180 ° by the rotor blades, so the pressure loss is less than the conventional water pump, compared to the conventional water pump The amount of pumping per hour increases and the effect of high head is also improved.
