본 고안은 화공약품등의 액체를 이송하는 펌프에 관한것으로서, 특히 화공약품 이송시 씰링역활을 하는 메카니칼씰 또는 그랜드 패킹의 마모로 인하여 화공약품이 누수되는 것을 방지하도록 누액집합실의 애트마이저 후측에 위치하게 회동축에 결합하는 패킹링을 스프링으로 탄발되게 하여 회동축과 부동시이트 사이를 개폐할 수 있게 하므로 화공약품들의 누설로 인한 기기의 파손과 마모등이 방지될 수 있도록 함을 목적으로한 펌프에 대한 것이다.The present invention relates to a pump for transporting liquids such as chemicals, and in particular, to prevent leakage of chemicals due to abrasion of mechanical seals or grand packings, which act as a sealing when transporting chemicals, A pump aimed at preventing the damage and wear of the device due to leakage of chemicals by opening and closing the packing ring coupled to the rotating shaft with a spring to open and close between the rotating shaft and the floating sheet. It is about.
종래의 펌프들은 화공약품 이송시 씰링역활을 하는 메카니칼씰 또는 그랜드 패킹의 마모등으로 인하여 가동중 액이 누수되어 고가의 화공약품이 낭비됨은 물론 이를 수리하기 위해서 가동중인 모우터를 정지시킨 다음 고가의 부품들을 교체하여야 되는 등 비경제적인 문제점과 누수로 인한 공해문제가 발생하였기 때문에 메카니칼씰을 사용치 않는 방향으로 연구하고는 있으나, 이 경우에는 설치장소가 한정되어 탱크의 상부에 액의 수위에 맞추어 설치하여야 하고 수직식설치등으로 인한 기존 배관의 변경이 요구되는 등 비효율적인 문제가 발생되었다.Conventional pumps leak liquids during operation due to wear of mechanical seals or grand packings, which act as a sealing when transporting chemicals, and waste expensive chemicals, as well as stopping expensive motors to repair them. Because of the uneconomical problems such as the need to replace parts and the pollution problem due to leakage, we are studying in the direction of not using mechanical seal, but in this case, the installation place is limited and installed according to the liquid level in the upper part of the tank. Inefficient problems such as the need to change the existing piping due to vertical installation.
또한 이는 작업상 상측 위치에 설치되므로 위험부담이 많고 고장시 즉시 조치를 취할 수 없는 등의 문제들도 있어 실용적이 못되었다.In addition, since it is installed in the upper position of work, there are many risks and it is not practical because there are problems such as the inability to take immediate action.
본 고안은 이와같은 문제점들을 해결할 수 있도록 고안한 것으로서, 애트마이저가 축착된 회동축에 패킹링을 결합하여 작동간과 스프링의 작용으로 이동자재토록 하므로 회동축의 원활한 회전운동과 누수로 인한 마모등을 방지할 수 있게 한 것이다.The present invention is designed to solve these problems, and the atomizer combines the packing ring with the constricted rotating shaft to allow movement between the operation and the action of the spring so that smooth rotational movement of the rotating shaft and wear due to water leakage can be achieved. It is to be prevented.
이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
모우터(M)의 회동축(4)선단에는 임펠러(5)를 연결구(6)로 착설하고 케이싱(1)과 백케이싱(2)사이의 중간 케이싱(3)내측에는 누액집합실(a)을 형성하여 이에 집합된 누액이 바이패스관(7)을 통해 흡입구(A)측으로 배출되게 한 펌프(P)에 있어서, 애트마이저(8)를 축착한 회동축(4)에 패킹링(14)을 결합하여 케이싱(1)의 격벽(1-1)및 이 격벽 내면에 부착하는 부동시이츠(9)에 각각 뚫은 축공의 내경과 상기 회동축(4)의 외경사이에 형성되는 공간부(α)를 개폐시켜주게 하고, 상기 패킹링(14)의 양측에는 홈(14-1)을 형성하여, 상기 회동축(4)에 보울트(16)로 고정하는 링(10)의 양측 현가대(11)단부에 힌지(17)로 축착한 "ㄱ"자형 작동간(12)의 내단부(12-1)를 끼워 결합하며, 이 작동간(12)의 외단부에는 회전추(13)를 고정착설하고, 또 링(10)과 패킹링(14)사이에는 스프링(15)을 개재시켜서 된 것이다.An impeller 5 is installed at the distal end of the rotating shaft 4 of the motor M as a connector 6, and a leakage-tightening chamber a is formed inside the intermediate casing 3 between the casing 1 and the back casing 2. In the pump (P) is formed so that the leakage fluid collected thereon is discharged to the inlet (A) side through the bypass pipe (7), the packing ring (14) on the rotating shaft (4) condensing the atomizer (8) Space portion (α) formed between the inner diameter of the shaft hole drilled in the partition wall 1-1 of the casing 1 and the floating sheets 9 attached to the inner surface of the partition wall and the outer diameter of the rotation shaft 4, respectively. ) And grooves 14-1 on both sides of the packing ring 14, and both side suspensions 11 of the ring 10 fixed to the pivot shaft 4 with bolts 16. The inner end portion 12-1 of the "a" shaped operation rod 12, which is affixed to the end by the hinge 17, is fitted to the end portion, and the rotary weight 13 is fixedly attached to the outer end portion of the operation rod 12. In addition, when the spring (15) is interposed between the ring (10) and the packing ring (14) It was turned on.
미설명 부호 "B"는 토출구, "18"은 리벳, "19"는 패킹링의 고무링, "20"은 플레이트, "21"은 받침대이다.Reference numeral "B" denotes a discharge port, "18" is a rivet, "19" is a rubber ring of a packing ring, "20" is a plate, and "21" is a pedestal.
이와같이 구성되는 본 고안은 모우터(M)에 전원이 통전되어 구동되면 회동축(4)이 회전되며 이렇게 되면 이 축에 보출트(16)로 고정된 링(10)도 함께 회전하므로 현가대(11)의 단붕에 힌지(17)로 축착된 "ㄱ"자형 작동간(12)도 함께 회전되기 때문에 작동간(12)의 외단에 착설된 회전추(13)가 원심력에 제 3 도의 가상선(R')과 같이 외측으로 이동하게 되므로 작동간(12)이 힌지(17)를 축으로 하여 반시계 방향으로 회전되어 내단부(12-1)가 좌측으로 이동하게 된다.The present invention constituted as described above is rotated by the rotating shaft (4) when the power is supplied to the motor (M), and in this case, the ring (10) fixed to the bolt 16 is also rotated together with the suspension ( Since the "a" shaped operation rod 12 condensed by the hinge 17 on the single shelf of 11 is also rotated together, the rotary weight 13 installed on the outer end of the operation rod 12 is applied to the centrifugal force of FIG. R ') is moved outward so that the operation 12 is rotated counterclockwise around the hinge 17 to move the inner end portion 12-1 to the left.
이렇게 되면, 상기 내단부가 양측홈(14-1)에 끼워져 있으므로 패킹링(14)을 회동축(4)에서 좌측으로 이동시켜 주게되어 케이싱(1)의 격벽(1-1)내면에 부착된 부동시이트(9)로 부터 떨어지게 하여 주므로 모우터(M)와 회동축(4)이 원활하게 회전될 수 있게하여 주고, 또 이에 따라 회동축(4)의 회전시 임펠러(5)이외의 다른 부품과 접촉되지 않으므로 회전마찰에 의한 마모가 전혀 없게되는 것이다.In this case, since the inner end is inserted into both grooves 14-1, the packing ring 14 is moved from the pivot shaft 4 to the left side, thereby floating the attachment to the inner surface of the partition wall 1-1 of the casing 1. Since it is separated from the sheet (9), the motor (M) and the rotational shaft (4) can be smoothly rotated, and accordingly the rotation of the rotational shaft (4) and other components other than the impeller (5) Since there is no contact, there is no wear caused by rotational friction.
한편, 모우터(M)가 구동되다가 정지를 하게 되면 원심력이 소멸되므로 패킹링(14)은 압축되었던 스프링(15)의 탄발력에 의해 회동축(4)에서 우측으로 이동되어 격벽(1-1)에 부착된 부동시이트(9)와 밀착됨과 동시에 회동축(4)과의 공간부(α)를 밀폐시켜 주게 되므로 누액이 침투되는 것을 방지할 수 있게 되는 것이다.On the other hand, since the centrifugal force is dissipated when the motor M is driven and stopped, the packing ring 14 is moved to the right side from the rotational shaft 4 by the elastic force of the spring 15 that has been compressed, so that the partition wall 1-1 is closed. In close contact with the floating sheet (9) attached to the) and at the same time to seal the space (α) with the rotating shaft (4) it is possible to prevent the leakage of leakage.
이와같이 사용되는 본 고안은 모우터(M)의 정지시에는 패킹링(14)이 스프링(15)의 탄발력으로 부동시이트(9)축으로 이동 밀착되어 이 시이트와 회동축(4)사이의 공간부(α)를 밀폐시켜 주어 누액이 침투되는 것을 방지하여 주며 모우터(M)가 회전시에는 원심력에 의한 회전추(13)의 작용으로 패킹링(14)이 부동시이트와 격리되어 마찰이 방지되게 하였으며, 또 누액집합실(a)의 누액은 바이패스관(7)을 통해 흡입구(A)측으로 이송되어졌다가 임펠러(5)의 회전력에 의하여 토출구(B)로 배출되게 하였고, 모우터(M)가 구동시에는 회동축(4)에 묻어 있는 누액은 원심력에 의해 비산되므로 부동시이트(9)와 회동축(4)사이의 공간부(α)를 통하여 누액이 침투되는 현상은 발생하지 않게 되는 등 매우 유용한 고안이다.In the present invention used in this way, when the motor (M) is stopped, the packing ring 14 is moved close to the floating sheet (9) shaft by the elastic force of the spring 15, the space between the sheet and the rotating shaft (4) Seals the part (α) to prevent leakage of the liquid leakage. When the motor (M) rotates, the packing ring 14 is isolated from the floating sheet by the action of the rotary weight 13 by centrifugal force to prevent friction. In addition, the leakage of the leakage collection chamber (a) was transferred to the suction port (A) through the bypass pipe (7) and discharged to the discharge port (B) by the rotational force of the impeller (5), the motor ( When M) is driven, the liquid leakage on the rotating shaft 4 is scattered by the centrifugal force so that the liquid leakage does not penetrate through the space portion α between the floating sheet 9 and the rotation shaft 4. Being a very useful design.
