본 고안은 자흡식 와류 펌프의 마중물 탱크에 관한 것이다.The present invention relates to a cargo tank of a self-priming vortex pump.

제1도는 종래의 자흡식와류 펌프구성도로서 펌프(1)의 흡입플렌지(2) 및 토출플렌지(3)는 펌프하측부위에 각기 형성하고 첵밸브(4)는 마중물탱크(5) 일측부에 형성하며 또한 토출 플렌지(3)와 연결되도록 PVC토출안내 파이프(6)를 마중물탱크(5) 일측내부에 수직상으로 입설한 것이다.1 is a diagram of a conventional self-priming vortex pump, in which the suction flange 2 and the discharge flange 3 of the pump 1 are respectively formed at the lower part of the pump, and the check valve 4 is located at one side of the pick-up tank 5. To form and also connected to the discharge flange (3) PVC discharge guide pipe (6) is installed vertically inside one side of the pick-up tank (5).

미성명부호 7은 펌프케이싱이고, 8은 펌프받침 체결보울트이며, 9는 마중물탱크(5)의 상부에 형성된 마중물 주입구이다. 위와 같은 종래의 자흡식 와류펌프 마중물탱크 구성에 있어서는 흡인관 플렌지와 토출플렌지가 펌프몸체하측부위에 부착되어 있어 실수요지가 펌프를 구입하여 설치할때 플렌지가 펌프 하측부위에 형성되어 있으므로 수도관과 연결된 토출관 플렌지와 우물과 연결된 흡인관 플렌지에 배관 작업시 보울트니트 체결을 할때 파이프렌치 스패니 공구를 사용하기가 불편하였고 또한 펌프를 양수하기 위해 흡입관 측에 있는 공기를 마중물 탱크의 공기분리실에서 마중물의 양을 많게하여 공기를 빨리 분리시킬 목적으로 마중물 탱크내부에 토출파이프를 설치하기가 어려워 마중물 탱크와 토출파이프를 분리제작하여 서로 압입하는 곤란성이 있었으며, 펌프 조립공정에 토출파이프를 펌프몸체에 압입하고 마중물탱크를 조립하여 일체로 도장한 후 도장을 건조시키기 위하여 고온 건조로를 통과시켜 상온에서 냉각하도록 되어있고 냉각시 토출파이프와 마중물 탱크의 재질이 PVC파이프와 주철로 되어있어 재질에 따른 냉각시간이 다르므로 냉각후 토출파이프에 틈새가 생기게되고 이로인하여 마중물이 이 틈사이로 흘러나가기 때문에 마중 물탱크에 물이 없어 흡입측의 공기를 분리시키지 못하므로 펌프가 계속 운전되어도 양수가 되지 아니하는 불량율이 많았으며, 또한 실수요자가 사용도중 오물등이 토출관을 막아 펌프내부에 있는 물이 밖으로 나오지 못하고 펌프내부를 계속 순환하게될 경우 이 남은 물이 임펠러와의 마찰에 의해 펌프내부 온도가 높아져서 증기가 발생하게되며 모우터가 계속 운전될 경우 펌프내부의 증기 압력이 점점 올라가게되어 펌프 내부는 고압으로되어 펌프의 취약부위가 파손하게되는 위험을 초래하게 되었다.Unidentified reference numeral 7 is a pump casing, 8 is a pump support fastening bolt, 9 is a pick-up inlet formed on the top of the pick-up tank (5). In the conventional self-priming vortex pump pumping tank configuration as above, the suction pipe flange and the discharge flange are attached to the lower part of the pump body, so the flange is formed at the lower part of the pump when the real point is purchased and installed. It is inconvenient to use the pipe wrench spanner tool when tightening the bolt on the suction pipe flange connected to the flange and the well. Also, the amount of water to be picked up in the air separation chamber of the tank in order to pump air from the suction pipe side to pump the pump. In order to separate the air quickly, it was difficult to install the discharge pipe inside the tank, and there was a difficulty of separating and manufacturing the tank and the discharge pipe. Then, the discharge pipe was press-fitted into the pump body during the pump assembly process. After assembling the tank and painting it integrally It is designed to pass through the high-temperature drying furnace to cool it at room temperature. During cooling, the material of the discharge pipe and the pick-up tank is made of PVC pipe and cast iron, so the cooling time is different according to the material. Since the pick-up water flows between these gaps, there is no water in the pick-up water tank, so the air on the suction side cannot be separated, so there is a lot of defective rate that the pump is not pumped even if the pump continues to run. If the water inside the pump does not come out and continuously circulates inside the pump, the remaining water is generated by the internal temperature of the pump due to the friction with the impeller, and the steam is generated. This rises and the inside of the pump becomes high pressure, so the weak part of the pump The risk that was caused.

본 고안은 상기한 문제점들을 해결하기 위해 펌프의 흡입 및 토출 플렌지 구성을 펌프몸체 윗쪽에 체결된 마중물 탱크 양측하부에 설치하고 토출파이프를 마중물 탱크와 일체로 주조 성형하며, 마중물 탱크내의 고압발생을 막기 위해 안전 밸브를 상측부위에 설치한 것으로 본 고안을 첨부된 제2도에서 제5도까지의 도면에 의하여 상세히 설명하면 다음과 같다.The present invention installs the suction and discharge flange configuration of the pump in the lower side of the tank of the intermediate tank fastened to the upper side of the pump body to solve the above problems, and cast the discharge pipe integrally with the intermediate tank, and prevents the high pressure in the intermediate tank When the safety valve is installed on the upper side in order to explain the present invention in detail by the accompanying drawings 2 to 5 as follows.

마중물 탱크(5)내의 첵밸브(4')와 연통되게 흡입통로(2')를 구획형성하고 여기서 다시 하방의 임펠러실(7')과 연통되게 유입통로(4")를 형성하며 또한 토출 플렌지(3)를 흡입통로(2')와 대향되게끔 정반대쪽에 구획벽(3')을 이용한 토출통로(3")를 형성하여 마중물 탱크(5)내의 물이 구획벽(3')의 상부로 넘어가서 토출통로(3")를 통하여 토출플렌지(3)에 연결된 미도시된 상수도관으로 토출할 수 있게 한 것이다.The suction passage 2 'is partitioned in communication with the check valve 4' in the cargo tank 5, where the inlet passage 4 "is further formed in communication with the lower impeller chamber 7 'and the discharge flange (3) is formed so that the discharge passage (3 ") using the partition wall (3 ') on the opposite side to face the suction passage (2') so that the water in the cargo tank (5) to the top of the partition wall (3 ') It is possible to discharge to the water pipe not shown connected to the discharge flange 3 through the discharge passage (3 ").

또한 마중물탱크(5)의 상부일측에 배기공(11)이 천설되어 있는 안전밸브(10)를 설치하여 마중물탱크(5)내에 정도이상의 압력이 가해졌을 때 시트(10')가 스프링(10")을 밀고 상승되어 내부 압력이 자동배출되게 하므로서 마중물 탱크(5)내에 일정압력이상이 걸리지 않게 설치한 것이며, 부호(5')는 마중물탱크(5)의 내부중앙에 충전되는 물의 공기분리실로서 임펠러실(7')과 연통되도록 배출통로(5")를 형성한 것이고, (12)는 펌프(1)와 연결된 전동모우터이며, (13)은 펌프(1)와 전동모우터(12)의 받침대이다.In addition, a seat 10 'is provided with a spring 10 "when a pressure relief valve 10 is installed on the upper side of the cargo tank 5 so that a pressure greater than or equal to the pressure in the cargo tank 5 is applied. ) Is installed so that internal pressure is automatically discharged and pushed up) so as not to be over a certain pressure in the cargo tank 5, and the symbol 5 'is an air separation chamber of water filled in the center of the cargo tank 5 A discharge passage 5 "is formed to communicate with the impeller chamber 7 ', (12) is an electric motor connected to the pump (1), and (13) is a pump (1) and an electric motor (12). Is the pedestal of.

이와 같이 구성된 본 고안에 따라 그 작용효과를 설명하면, 마중물탱크(5)의 마중물 주입구(9)에 1000cc정도의 물을 주입한후 전동모우터(12)를 ON하면 펌프(1)의 축에 고착된 원주상에 많은 홈을 가진 임펠러(7")가 회전되어 우물물을 압상 흡인시키며 이는 곧 흡입통로(2')로 흡입되어져 첵밸브(4)을 밀고 첵밸브실실(4')을 거쳐서 임펠러실(7')과 연통된 유입통로(4')를 통하여 임펠러실(7')로 유입되며 이렇게 유입된 물은 임펠러(7")의 회전 원심력에 의하여 속도에너지를 받게되며 임펠러실(7')내의 임펠러(7")와 케이싱(7)내벽사이의 물통로부터에서 와류가 생겨 난류마찰에 의하여 압력 에너지로 변환되어 마중물 탱크(5)의 토출통로(3")를 통하여 토출하게 된다.Referring to the operation effect according to the present invention configured as described above, after the injection of about 1000cc of water into the cargo inlet (9) of the cargo tank (5) to turn on the electric motor 12 to the shaft of the pump (1) An impeller (7 ") with many grooves on the fixed circumference is rotated to suck up the well water, which is sucked into the suction passage (2 '), pushing the check valve (4) and passing through the check valve chamber (4'). It flows into the impeller chamber 7 'through the inflow passage 4' in communication with the seal 7 '. The water thus received receives the velocity energy by the rotary centrifugal force of the impeller 7' and the impeller chamber 7 '. Vortex flows from the bucket between the impeller 7 "and the inner wall of the casing 7, and it is converted into pressure energy by turbulent friction and discharged through the discharge passage 3" of the cargo tank 5.

그리고 흡입측의 첵밸브(4)는 물의 역류를 방지하여 펌프(1)가 정지시 진공부와 압력부를 분리하는 역할을 하며, 펌프(1) 운전시에는 즉시 물이 나오는 자흡식 와류 펌프로, 본 고안은 흡입플렌지(2)와 토출플렌지(3)가 마중물탱크(5) 양측 하부에 대향지게 형성되어 있기 때문에 흡입관과 토출관을 연결부착하기가 수월하고 실수요자가 설치하기에 편리하며, 또한 펌프(1) 몸체의 구조도 간단히 되는 잇점이 있으며, 마중물탱크(5)의 내부중앙공기 분리실(5')과 구획하는 구획벽(3')을 형성하여 토출통로(3")를 마중물탱크(5)와 일체로 주조성형하였으므로 종래의 PVC 토출원안내 파이프(6)가 빠져 양수가되지 않는 결점을 방지할 수 있다.In addition, the suction valve 4 (4) prevents the reverse flow of water to separate the vacuum portion and the pressure portion when the pump (1) is stopped, and when the pump (1) operation is a self-priming vortex pump that immediately comes out of the water, The present invention is because the suction flange (2) and the discharge flange (3) is formed opposite to the lower side of the cargo tank (5), it is easy to connect and attach the suction pipe and the discharge pipe, it is convenient for the real user to install the pump (1) The structure of the body also has the advantage of simplifying, forming a partition wall (3 ') partitioning with the internal central air separation chamber (5') of the cargo tank (5) to discharge the discharge passage (3 ") tank ( Since it is integrally molded with 5), it is possible to prevent the defect that the conventional PVC discharge source guide pipe 6 falls out and is not pumped.

또한 마중물탱크(5) 일측상부에 안전밸브(10)을 설치하여 주므로 펌프(1) 내부의 압력이 일정 압력이상의 형성되면 안전밸브(10)의 시트(10')가 자동으로 작동되어 배기공(11)으로 압력이 빠져나가게 됨으로 펌프(1) 내부에는 일정압력이상이 걸리지 않게 되어 압력에 의한 펌프의 파손을 방지할 수 있는 유용한 고안이다.In addition, since the safety valve 10 is installed on one side of the pick-up tank 5, when the pressure inside the pump 1 is set to a predetermined pressure or more, the seat 10 ′ of the safety valve 10 is automatically operated to discharge the exhaust hole ( 11) It is a useful design to prevent damage to the pump due to the pressure is not to take a certain pressure or more inside the pump (1) because the pressure is released.

이러한 본 고안의 안전밸브를 설치하는 목적은 실 수요자가 사용도중 수도콕크를 잠그고 펌프를 정지시키지 않았을 경우를 예상하여 설치한 것으로, 수도콕크를 잠그고 펌프를 정지시키지 않았을 경우, 단절 운전이 되어 펌프내부에 있는 물이 밸브가 잠겼기 때문에 밖으로 나자지 못하고 펌프내부를 계속 순환하게 되며, 이 남은 물이 임펠러와의 마찰에 의하여 펌프 내부 온도가 점점 높아져서 증기가 발생하게되며, 펌프가 점점 운전될 경우 펌프내부의 증기 압력이 점점 올라가 펌프 내부는 고압이되어 펌프의 취약부위가 가속 또는 폭발하게 되는 위험을 초래하게 된다.The purpose of installing the safety valve of the present invention is to anticipate the case where the actual consumer locks the water cock and stops the pump while in use, and when the water cock is locked and the pump is not stopped, the pump is disconnected and operated. Water inside the pump is circulated inside the pump because it does not go out because the valve is locked, and the remaining water becomes steam by the internal temperature of the pump is increased by friction with the impeller, and when the pump is operated, the pump As the steam pressure inside the pump increases, the inside of the pump becomes high pressure, which causes the weak point of the pump to accelerate or explode.

본 고안은 이상과 같은 실수요자의 잘못 운전에 의해 펌프내부에 고압의 형성을 방지하기 위하여 펌프내부의 압력이 단절 수도콕크를 막았을 때의 압력 이상이되면 안전밸브가 자동적으로 작동되어 펌프의 파손 또는 폭발의 위험을 방지하기 위한 것이다.In order to prevent the formation of high pressure inside the pump due to the mistaken operation of the mistaken user, the safety valve is automatically operated when the pressure inside the pump becomes higher than the pressure when the disconnection water cock is blocked. It is to prevent the danger.

또한 펌프에 연결하는 흡입관과 토출관의 연결플렌지를 펌프몸체 하부에 형성하였던 것을 마중물탱크에 직접성형하여 펌프 설치시 좁은 면적에서의 작업이 쉽고 종래의 마중물탱크내에 설치하던 PVC 토출안내 파이프 없이 주조시 마중물탱크에 토출통로를 성형하였으므로 마중물의 누수없이 일정량의 많은물을 공기분리실에 충전할 수 있어 흡입측의 공기를 완전 분리하여 펌프의 양수효율을 증진시켜주는 효율좋고 사용이 간편한 고안인 것이다.In addition, the connection flange of the suction pipe and the discharge pipe connected to the pump is formed at the lower part of the pump body, so it is easy to work in a small area when installing the pump, and it is easy to cast without the PVC discharge guide pipe installed in the conventional tank. Since the discharge passage is formed in the dead water tank, a large amount of water can be filled in the air separation chamber without leaking the dead water, which is an efficient and easy-to-use design that improves the pumping efficiency of the pump by completely separating the air on the suction side.
