The fluid resistance portion of the fluid inlet hole is located between the, and the impeller is formed by a motor capable of forward and reverse rotation It has a feature configured to be.
이하, 본 고안의 한 실시예를 도면에 따라 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1은 펌프본체로서, 연부에 유체출입구(2)(2a)를 가지고 전방중앙에 펌핑실(3)이 형성되어 있고, 이의 중심부에는 모우터(도시생략)와 연결된 회전축(5)이 외부로부터 내부로 관통되어 있으며 상기 펌핑실(3) 주변의 대접면(1a)에는 상기 유체출입구(2)(2a)와 각각 상통되는 통공(4)(4a)이 형성되어 있다.1 is a pump main body, and has a fluid inlet (2) (2a) at the edge thereof, and a pumping chamber (3) is formed at the front center, and at the center thereof, a rotating shaft (5) connected to a motor (not shown) is connected from the inside. Through holes (4a) are formed in the contact surface (1a) around the pumping chamber (3) and communicate with the fluid inlet (2) (2a), respectively.
상기 펌핑실(3)의 하부에는 자흡수가 저수되는 광역부(3a)가 형성되며 펌핑실(3)의 낸부로 관통된 회전축(5)에는 임펠러(6)가 체결너트(7)(7)로 설치되어 있다.The lower portion of the pumping chamber (3) is formed with a wide area (3a) for storing the self-absorption, and the impeller (6) is fastened to the rotary shaft (5) penetrated into the inner part of the pumping chamber (3) It is installed.
또, 상기의 회전축(5)이 설치된 모우터(도시생략)는 스위치조작에 따라 정,역회전을 하는 모우터이다.In addition, a motor (not shown) provided with the rotary shaft 5 is a motor that performs forward and reverse rotation according to a switch operation.
8은 뚜껑체로서, 중앙에 상기 축단과 이에 체결된 너트(7)(7)가 여유있게 들어갈 수 있는 요입부(9)가 형성되고 이 요입구(9)의 주변으로 호형요홈(10)이 형성되고 그 일부에 호형요홈(10)이 결여된 유체저항부(10a)가 상기 펌프본체(1)의 대접면(1a)과 대립하는 대접면(8a)에는 상기 통공(4)(4a)과 일치되는 통공(11)(11a)이 형성되고 상기 요입부(9)의 인근 양측에는 유체출입공(12)(12a)이 천공되어 이중 한 유체출입공(12)은 상기의 통공(11)과 내부통로(13)로 연결되고 다른 유체 출입공(12a)은 다른 통공(11)과 내부통로(13a)로 상통되도록 구성되어 있다.8 is a lid body, and a concave inlet 9 is formed in the center to allow the shaft end and the nuts 7 and 7 fastened thereto to be relaxed, and the arc-shaped groove 10 is formed around the concave inlet 9. The through-holes 4 and 4a are formed on the opposing surface 8a, which is formed and partially opposes the opposing surface 1a of the pump body 1, and the fluid resistance portion 10a lacking the arc groove 10 is formed therein. Consistent through-holes 11 and 11a are formed, and fluid access holes 12 and 12a are drilled on both sides of the concave inlet 9 so that one of the fluid access holes 12 is formed in the through-hole 11. It is connected to the inner passage 13 and the other fluid inlet 12a is configured to communicate with the other passage 11 and the inner passage 13a.
상기 구조용 유체저항부(10a)는 유체출입공(12)(12a) 사이에 위치함이 원칙이다.In principle, the structural fluid resistance part 10a is located between the fluid access holes 12 and 12a.
상기와 같이 구성된 뚜껑체(8)는 상기의 펌프본체(1)에 덮은 다음 보울트공(14)(14)을 통하여 체결보울트(15)로 체결된다.The cover body 8 configured as described above is covered with the pump body 1 and then fastened to the fastening bolt 15 through the bolt holes 14 and 14.
이상과 같이 구성된 본 고안은 펌핑실(3)이 환형요홈(10)이 형성된 부분은 내부공간이 비교적 크고 유체저항부(10a)가 형성된 부분은 그 내부공간이 잘록부가 생기게 되므로 임펠러(6)가 회전할때 임펠러(6)에 의해 회전되는 유체는 유체저항부(10a)로 인한 잘록부를 통과할때 저항을 가장 많이 받도록 되어 있으며 상기 유체저항부(10)의 양측에 유체출입공(12)(12a)이 형성되어 있으므로, 임펠러(6)가 제3도 (b)에서 화살표 방향으로 회전할때는 유체저항부(10a)를 중심으로 유체 출입공(12a)쪽이 저기압이므로 유체출입공(12a)으로 유체가 들어오고 유체출입공(12a)족으로 들어온 유체는 임펠러(6)에 의해 이동되다가 유체저항부(10a)에 막히게 되므로 유체출입공(12)으로 빠져나가게 된다.According to the present invention configured as described above, the part where the pumping chamber 3 is formed with the annular recess 10 has a relatively large internal space, and the part where the fluid resistance part 10a is formed has an inner space where the impeller 6 is formed. The fluid rotated by the impeller 6 when rotating is subjected to the most resistance when passing through the cut-off portion caused by the fluid resistance part 10a, and the fluid entry hole 12 (the two sides of the fluid resistance part 10) ( Since 12a) is formed, when the impeller 6 rotates in the direction of the arrow in FIG. 3 (b), the fluid inlet hole 12a toward the fluid inlet hole 12a is about low pressure due to the fluid resistance hole 10a. Fluid enters and the fluid entering the fluid access hole (12a) is moved by the impeller (6) is blocked by the fluid resistance portion (10a) is to exit to the fluid access hole (12).
따라서, 임펠러(5)가 시계방향(제3도 (a)(b)의 화살표방향)으로 회전할 경우에는 유체출입구(2a)로 유체가 흡입되어 서로 맞닿아 있는 통공(4a)(11a)을 거쳐 내부통로(13a)와 유체출입공(12a)을 통해 펌핑실(3)로 들어온뒤 임펠러(6)의 회전력에 의해 화살표방향으로 이동되다가 유체저항부(10a)에 막혀 유체출입공(12)을 통해 빠져나가 내부통로(13)와 통공(11)(4)을 차례로 통과하여 유체 출입구(2)로 배출된다.Therefore, when the impeller 5 rotates in the clockwise direction (the arrow direction in FIG. 3 (a) (b)), the fluid is sucked into the fluid inlet 2a to contact the through holes 4a and 11a which are in contact with each other. After entering the pumping chamber (3) through the inner passage (13a) and the fluid access hole (12a) is moved in the direction of the arrow by the rotational force of the impeller (6) is blocked by the fluid resistance portion (10a) fluid access hole (12) Exit through the inner passage 13 and the through-hole (11) (4) in order to be discharged to the fluid inlet (2).
다음, 임펠러(6)가 반시계방향으로 회전할때는 위의 설명과 반대 작용에 의해 유체출입구(2)로 유체가 흡입되어 통공(4)(11)과 내부통로(13) 및 유통공(12)을 통해 펌핑실(3)로 유입된 후 임펠러(6)의 회전에 의해 유체가 이동되어 유체출입공(12a)과 내부통로(13a)르 거쳐 통공(11a)(4a)을 통하여 유체출입구(2a)로 배출된다.Next, when the impeller 6 rotates in a counterclockwise direction, the fluid is sucked into the fluid inlet 2 by the action opposite to that described above, so that the through hole 4, 11, the inner passage 13, and the outlet hole 12 are rotated. After entering the pumping chamber (3) through the fluid is moved by the rotation of the impeller (6) through the fluid inlet hole (12a) and the inner passage (13a) through the through hole (11a) (4a) fluid inlet (2a) To be discharged.
이상과 같이 동작하는 본 고안은 모우터(도시되지 않음)를 스위치로 조작하여 모우터의 회전방향을 바꾸어주면 임펠러(6)가 시계방향 또는 반시계방향으로 회전하면서 유체출입구(2)(2a)의 유체의 흐름이 정,역방향으로 절환하게 되므로, 펌프와 연결된 유에 저항탱크나 배관 등의 시설물을 그대로 고정시킨 상태에서 유체의 흐름방향을 임의로 변경시킬 수 있으므로 종래와 같이 펌프와의 연결호스 등을 바꾸어 끼우는 등의 번거로움이 없이 사용할 수 있어 작업에 신속하게 임할 수 있고 작업속도가 빨라지며 펌프의 사용이 편리해지는 것 등의 특징을 지닌 것이다.The present invention, which operates as described above, operates the motor (not shown) to switch the direction of rotation of the motor so that the impeller 6 rotates clockwise or counterclockwise while the fluid inlet (2) (2a) Since the flow of fluid changes in the forward and reverse directions, the flow direction of the fluid can be arbitrarily changed while the facilities such as the resistance tank or the pipe are fixed to the oil connected to the pump. It can be used without the hassle of replacement, so it can work quickly, work speed is faster, and the use of pump is convenient.
