Description

수분 분리구조를 갖는 진공 자흡식 원심펌프{A centrifugal pump}Vacuum self-priming centrifugal pump having a water separation structure {A centrifugal pump}

본 고안은 수분 분리구조를 갖는 진공 자흡식 원심펌프에 관한 것으로서, 더욱 상세하게는 수분 분리구조를 갖는 진공 자흡식 원심펌프에 있어서, 흡입되는 공기 중에 함유된 수분이 관성 충돌에 의하여 집수 제거되게 하여서, 진공을 발생시키는 진공펌프로의 수분유입을 차단하여 윤활오일의 변질을 방지할 수 있도록 함을 목적으로 한 것이다.The present invention relates to a vacuum self-priming centrifugal pump having a water separation structure, and more particularly, to a vacuum self-priming centrifugal pump having a water separation structure, in which water contained in the air to be sucked is collected and removed by inertia collision. In order to prevent the deterioration of the lubricating oil by blocking the inflow of water into the vacuum pump to generate a vacuum.

일반적으로, 원심펌프는 회전축에 연결된 회전차(임펠러)와 이를 지지하고, 입수와 토수를 일정하게 유지시켜주는 케이싱과 물의 유출을 막아주는 패킹 또는 씰, 회전을 유지시켜주는 베어링 등으로 이루어져 있으며, 특히 회전차에서 방수되는 물이 일정한 안내깃(가이드베인)을 통하여 밖으로 배출되는 펌프를 터어빈 펌프라 하며 대용량의 양수 또는 원심펌프, 다단 원심펌프 등에 이용되어져 왔다.In general, the centrifugal pump consists of a rotor (impeller) connected to a rotating shaft, a casing that supports it, keeps water supply and discharge constant, a packing or seal that prevents the outflow of water, and a bearing that maintains rotation. In particular, the pump that is discharged out of the water through the constant guide vane (guide vane) is a turbine pump and has been used for large-capacity pumping or centrifugal pump, multi-stage centrifugal pump.

이상과 같은 원심펌프는 최초 구동시 펌프 자체만으로는 펌프보다 수위가 현저히 낮은 수원의 물을 흡입하여 끌어올리지 못하므로 자흡이라는 일종의 선행 작 업과정을 거쳐 펌프 및 흡수관에 물을 완전히 채워 회전차의 회전에 따라 원심력을 발생시킬 수 있는 수류를 형성해야 한다. 이러한 작업을 수행할 장치를 자흡장치(Priming system)라고 한다.As the centrifugal pump as described above does not suck up the water from the water source, which is significantly lower than the pump, when the pump is driven alone, the pump and the absorber tube are completely filled with water through the prior operation process called self-suction to rotate the rotor. In accordance with the present invention, a stream of water capable of generating centrifugal force must be formed. The device to perform this task is called a priming system.

상기한 바와 같은 원심펌프의 자흡장치에는 펌프에 물주입구를 두어 물을 공급하는 원시적인 방법 이외에도 진공펌프를 이용한 방법, 펌프를 구동시켜 주는 엔진의 배기가스의 배출속도 또는, 흡기가스의 흡입압력 등을 이용한 방법, 펌프 케이싱의 구조를 변경하여 잔수탱크를 설치하여 잔수를 이용한 방법 등 여러 가지가 있다.In addition to the primitive method of supplying water by providing a water inlet to the pump, the method of using a vacuum pump, the discharge rate of the exhaust gas of the engine driving the pump, the suction pressure of the intake gas, etc. There are various methods such as using a method, changing the structure of the pump casing, and installing a residual tank to use the residual water.

상기 자흡장치 중 진공펌프를 이용한 자흡장치는 효율과 성능, 자흡의 신속성이 가장 뛰어난 편심 로터리 베인 진공펌프가 사용되고 있으며 흡수관과 원심펌프의 일부 또는, 전부를 진공으로 하여 수원의 물을 펌프까지 일차로 끌어 올려주는 것이다.The magnetic suction device using the vacuum pump of the magnetic suction device is the eccentric rotary vane vacuum pump, which has the highest efficiency, performance, and rapid self-absorption, and uses a part or all of the absorption pipe and the centrifugal pump as a vacuum to pump water from the source to the pump. To pull it up.

이러한 자흡장치는 진공펌프와 진공펌프를 구동시켜주는 구동장치 및, 원심펌프와 흡수관을 밀폐하여 주는 역류방지 밸브를 설치하여야 하고, 원심펌프와 흡수관에 물이 완전히 흡입되었을 때, 진공펌프의 회전을 정지시켜주는 장치와, 물이 진공펌프로 유입되지 못하도록 하여 주는 지수밸브, 진공펌프의 마찰과 진공 효율을 높이기 위하여 공급하여 주는 진공오일 공급장치, 원심펌프 및 흡수관이 밀폐되어야 함에도 불구하고 장치에 이상이 발생되어 진공이 이루어지지 않고 원심펌프와 흡수관에 물이 흡입되지 못할 경우에는 일정한 시간 후에는 진공펌프가 회전을 정지하도록 하여 주는 장치 등으로 구성되어 있다.Such a self-priming device should be equipped with a vacuum pump and a driving device for driving the vacuum pump, and a non-return valve for sealing the centrifugal pump and the absorption tube. When the water is completely sucked into the centrifugal pump and the absorption tube, Despite the fact that the device to stop the rotation, the water valve to prevent the water from entering the vacuum pump, the vacuum oil supply device to supply the friction and vacuum efficiency of the vacuum pump, the centrifugal pump and the absorption pipe should be sealed In the event that an abnormality occurs in the apparatus and no vacuum is generated and water cannot be sucked into the centrifugal pump and the absorption tube, the vacuum pump stops rotation after a certain time.

한편, 상기 진공펌프를 이용한 자흡장치는 진공오일이 공급되어 배기와 함께 토출구로 배출되도록 제작되어 있으며, 원심펌프 장치의 구조상 진공펌프로 인하여 원심펌프와 흡수관에 충만된 물이 지수밸브에서 완전히 차단되지 못하고 일부 진공펌프로 유입됨으로써 오일이 변질되어 폐기되어야 하는바, 값비싼 오일의 낭비와 환경 및 폐수를 오염시키는 커다란 요인이 되었으며 또한 하부로 배출되는 물과 기름은 소방대원의 작업에도 커다란 지장을 초래하였다.On the other hand, the self-priming device using the vacuum pump is supplied so that the vacuum oil is supplied and discharged to the discharge port together with the exhaust, and due to the structure of the centrifugal pump device, the water filled in the centrifugal pump and the absorption tube is completely blocked from the water valve by the vacuum pump. The oil has to be discarded due to the inflow of some vacuum pumps, which is a big factor in waste of expensive oil and polluting the environment and wastewater. Caused.

이에 따라 실용신안 공개 1999-002145호에 공개된 바와 같이 상기 진공펌프(220)와 원심펌프(210) 사이에 충분한 크기의 공기물분리탱크(230)를 구비하고, 원심펌프(210)에서 유입된 물이 진공펌프(220)로 들어가지 못하도록 자흡유도관(231)을 공기물분리탱크(230) 하부로 연장 형성하며, 공기가 진공펌프(220)로 빨려들어가는 배관의 전단부에는 합성수지 등의 부구(232)와 부구안내판(233)을 설치하여 물이 공기물분리탱크(230)에 충만 되었을 시에도 진공펌프(220)로 유입되지 못하도록 하며, 상기 공기물분리탱크(230)의 상부와 하부에는 각각 배수밸브(234)를 두 개로 설치하여 진공펌프가 작동되는 동안만 닫혀질 수 있도록 하고, 상기 진공 오일탱크(240)는 상부에 에어벤트를 충분히 크게 설치하고 진공펌프(220)로부터 토출된 공기와 기름이 분리될 수 있는 토출구를 진공 오일탱크(240)의 일측 상부에 연결장착하여 공기는 에어벤트 밖으로 배출되고 진공오일은 진공 오일탱크(240)에 남아 순환하게 되는 것이다. Accordingly, as disclosed in Korean Utility Model Publication No. 1999-002145, the air separation tank 230 having a sufficient size is provided between the vacuum pump 220 and the centrifugal pump 210 and flowed in from the centrifugal pump 210. In order to prevent water from entering the vacuum pump 220, the self-contained induction pipe 231 extends to the lower portion of the air water separation tank 230, and air is sucked into the vacuum pump 220 at the front end of the pipe, such as a synthetic resin buckle. 232 and the guiding plate 233 is installed so that the water does not flow into the vacuum pump 220 even when the water is filled in the air separation tank 230, the upper and lower portions of the air water separation tank 230 Each of the two drain valves 234 may be installed to be closed only while the vacuum pump is operating. The vacuum oil tank 240 may have air vents large enough to be installed thereon and the air discharged from the vacuum pump 220 may be closed. And the discharge hole where oil can be separated Mounted connection to one side of the top 051 of the tank 240, air is discharged from the air vent and vacuum oil is to be circulated in vacuum it left an oil tank 240.

그러나, 상기한 바와 같은 종래의 원심펌프는 진공펌프에 의하여 자흡유도관으로 유입되는 공기가 공기물분리탱크의 하부에 채워지는 잔수에 침수된 상태로 분 리되어서 진공펌프로 유입되게 구성되어 있어 다량의 수분을 함유한 습증기 상태로 유입되어 진공펌프로의 수분 유입을 유발하여 진공펌프의 윤활을 위한 오일이 변질되는 문제점이 있었다.However, in the conventional centrifugal pump as described above, the air flowing into the self-contained induction pipe by the vacuum pump is separated into the residual water filled in the lower part of the air water separation tank, so that it is configured to flow into the vacuum pump. There was a problem in that the oil for lubrication of the vacuum pump was deteriorated by inflow into the wet steam state containing moisture, causing the water to flow into the vacuum pump.

이에, 본 고안은 상술한 바와 같이 공기물분리탱크를 통하여 진공펌프로 흡입되는 공기가 다량의 수분을 함유한 상태이어서 진공펌프로의 수분 유입을 유발하여 오일의 변질을 유발하는 문제점을 해결할 수 있도록 한 것이다.Thus, the present invention is to solve the problem that the air sucked into the vacuum pump through the air separation tank as described above contains a large amount of water, causing water inflow into the vacuum pump to cause the deterioration of oil It is.

즉, 본 고안은 수분 분리구조를 갖는 진공 자흡식 원심펌프에 있어서, 흡입되는 공기중에 함유된 수분이 관성 충돌에 의하여 집수 제거되게 하는 물분리판을 구비한 것이다.That is, in the vacuum self-priming centrifugal pump having a water separation structure, the present invention includes a water separation plate for collecting water contained in the sucked air by inertia collision.

따라서, 본 고안은 공기물분리탱크의 내부에 물분리판을 구비함으로써 진공펌프에 의하여 관성 흡입되는 공기가 상기 물분리판에 충돌되어 집수 됨으로써 진공펌프로 유입되는 공기 중의 수분이 완전히 제거 공급되어 수분으로 인한 오일 변질이 방지되는 것이다.Therefore, the present invention is provided with a water separation plate inside the air water separation tank, the inertial suction air by the vacuum pump collides with the water separation plate to collect the water in the air flowing into the vacuum pump is completely supplied This is to prevent oil deterioration.
