Description

대형 양수기{large water meter}Large water meter

본 고안은 양수기의 개량구조에 관한 것으로 보다 구체적인 것은 대형 양수기의 흡입부와 회전축의 축잡이 부분을 개량하여 보다 고속회전이 가능하면서 수리관리가 편리하도록 만든 것이다.The present invention relates to an improved structure of the water pump, and more specifically, to improve the suction part of the large water pump and the shaft part of the rotating shaft to make it possible to rotate at a higher speed and to facilitate maintenance.

종래의 대형 양수기는 임펠라에 연결되는 흡입관로가 양수기 통체 전면 문짝에 설치되어 있어서 임펠라 회전축을 수리할 경우 문짝을 열고 양수관로를 분해하여 수리해야 하므로 시간이 많이 소요되는 불편이 있고 회전축의 축잡이 부분이 고속회전할 때 냉각이 여의치 않아 쉽게 과열되어 메카니컬씰과 같은 고가의 부품이 손상되어 비용부담이 많아지고 내구성이 떨어지는 문제가 있었다.Conventional large water pump has a suction pipe that is connected to the impeller is installed on the front door of the pump body, when the impeller rotating shaft is repaired, it is time-consuming and inconvenient to take time because it needs to be disassembled and repaired. When the high speed rotation, the cooling is not easy to overheat easily damaged expensive components such as mechanical seals, there was a problem that the cost burden increases and durability is poor.

본 고안은 위와 같은 종래의 불편을 시정하기 위하여 개발한 것으로 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention was developed in order to correct the conventional inconvenience as described above with reference to the accompanying drawings in detail as follows.

양수기몸통(1)의 전면부에 흡입관로(2)를 형성하고 내부에 양수실(3)을 형성하여 임펠라(3a)를 장치하고 흡입관로(2)로 흡입된 물을 양수실(3)을 통해 배출관로(4)로 배출케 하고 양수실(3) 외측에 임펠라 축잡이부(5)를 설치하는 대형양수기에 있어서, The suction pipe passage (2) is formed on the front of the pump body (1), and the pumping chamber (3) is formed therein to install the impeller (3a), and the water sucked into the suction pipe passage (2) In the large water pump to discharge to the discharge pipe path (4) through the impeller holding part (5) outside the pumping chamber (3),

흡입관로(2)와 연결되는 양수실(3) 전면에 외주면을 따라 일정간격에 암나사공(31)이 있는 개방부(30)를 형성하여 이곳에 외주면에 체결공(33)이 형성된 덮개(32)를 덮어 체결공(33)에 보울트(34)를 끼워 암나사공(31)에 나사조립하는 수단으로 덮개(32)를 전면부에서 착탈시킬 수 있게 구성 하고 양수실(3) 후면으로 형성된 축잡이부(5)의 급유실(6)내측 구멍(60) 메카니컬씰 고정홈(61)을 만들어 메카니킬씰(62)를 삽입하고 그 외측면에 접촉되게 메카니킬씰 회전자(63)를 삽입하여 임펠라 회전축 외면에 장치된 코일스프링(65)으로 가압하되 메카니컬씰의 고정자(62)와 회전자(63)의 중심과 회전축(35)사이에 간격부(가)를 형성하여 회전자(63) 중심공 내측에 씰 패킹(64)을 끼우고 급유실 외측구멍에 오일리테너(66)를 끼워서 급유실의 오일이 메카니컬씰의 중심간격부(가)로 연통되어 회전축 외면으로 급유되게한 구성이다.Cover 32 having a fastening hole 33 formed on the outer circumference thereof by forming an opening 30 having a female thread hole 31 at a predetermined interval along the outer circumference of the pumping chamber 3 connected to the suction pipe passage 2. ) And the catcher formed at the rear of the pumping chamber 3 by attaching the bolt 34 to the fastening hole 33 and screwing the female screw hole 31 so that the cover 32 can be detached from the front part. Make the mechanical seal fixing groove 61 of the inner hole 60 of the oil supply chamber 6 of the section 5, insert the mechanical seal 62, and insert the mechanical seal seal rotor 63 to contact the outer surface thereof. Pressurized by the coil spring (65) installed on the outer surface of the impeller rotary shaft, but formed a gap (a) between the center of the stator 62 and the rotor 63 of the mechanical seal and the rotation shaft 35 to the center of the rotor (63) Insert the seal packing 64 inside the ball and insert the oil retainer 66 into the outside hole of the oil supply chamber so that the oil in the oil supply chamber is the center gap of the mechanical seal. It communicates a configuration in which the fuel supply causes the rotating shaft outer surface.

이와같이된 본 고안은 양수기의 몸통(1)의 내부에 형성된 양수실(3)에 장치된 임펠라(3a) 회전축(35)이 축잡이부(5)에 연통된 양수실과 양수실 외측으로 형성된 급유실(6)을 통과하므로 급유실에 저장된 오일과 양수실의 물이 접촉한 상태로 회전이 되는데 급유실(6)의 오일은 외측리테너(66)와 내측 메카니컬씰(62)(63) 및 씰패킹(64)에 의하여 회전축 외면에 깊숙이 급유 되어서 메카니컬씰의 회전자 고정자 사이에 충분한 오일을 급유하여 메카니컬씰의 윤활작용을 도와주게 되며 양수실과 구획이 되면서 회전축을 지지하기 때문에 윤활 효과가 탁월하며 메카니컬씰의 파손을 막고 고속회전에도 쉽게 과열되지 않는 이점이 있고 냉각이 원활하게 되는 이점도 있으며 양수실(3)의 전면으로 개방부(30)가 형성되어서 덮개(32)가 장착되어 보울트에 의하여 개폐되므로 임펠라를 비롯하여 베어링과 같은 물품을 수리할 때 흡입관로를 그대로 두고 몸통의 전면을 개방하여 수리를 할 수 있는 이점이 있어서 사용이 편리하게 되는 이점을 얻는 것이다.The present invention as described above has an impeller (3a) rotary shaft 35 installed in the pumping chamber (3) formed inside the body (1) of the pumping machine and the oil supply chamber formed outside the pumping chamber and the pumping chamber communicated to the holding portion (5) Since it passes through (6), the oil stored in the oil supply chamber is rotated in contact with the water in the pumping chamber. The oil in the oil supply chamber 6 is the outer retainer 66, the inner mechanical seals 62, 63, and the seal. It is lubricated deeply on the outer surface of the rotating shaft by the packing 64 to supply enough oil between the rotor stator of the mechanical seal to help lubrication of the mechanical seal. It prevents the seal from being damaged and does not easily overheat even at high speed. It also has the advantage of smooth cooling. The opening part 30 is formed at the front of the pumping chamber 3 so that the cover 32 is mounted and opened and closed by the bolt. When repairing items such as low impellers and bearings, there is an advantage that can be repaired by opening the front of the body while leaving the suction pipe intact, and thus it is easy to use.
