Abstract

According to the present invention, a pump operated without water comprises: a casing; an impeller; and a liner ring inserted into the inner circumferential surface of the casing and inserted into the outer circumferential surface of the impeller. The liner ring has magnetic lubrication properties and is made of a high-strength carbon-carbon composite material. Therefore, the liner ring is not burnt, deformed, and broken even if the pump is operated without water, so that the pump can be stably operated without water. Therefore, the present invention does not require an apparatus to supply the water to the pump during pump inspection, so that operating costs can be reduced.

Description

무급수 구동이 가능한 펌프{PUMP CAPABLE OF OPERATING WITHOUT WATER}[0001] PUMP CAPABLE OF OPERATING WITHOUT WATER [0002]

본 발명은 무급수 구동이 가능한 펌프에 관한 것이다.The present invention relates to a pump capable of pumpless operation.

양.배수장에 배수나 급수를 위한 펌프가 설치된다.A drainage or a pump for water supply is installed in the drainage area.

펌프는 주기적으로 점검을 받는다. 펌프 점검 시 펌프내로 물이 인위적으로 공급된다.The pump is periodically inspected. Water is artificially supplied into the pump when the pump is checked.

그 이유는, 물 공급 없이(무급수 상태) 펌프가 구동되면, 라이너링이 소착, 변형, 파손되기 때문이다. 라이너링은 누설손실을 줄이기 위해, 일정한 간극을 두고 케이싱의 내주면에 삽입되고 임펠러의 외주면에 삽입되는 부품이다.This is because, when the pump is driven without water supply (in a non-charged state), the liner ring is seized, deformed, and broken. The liner ring is a part that is inserted into the outer peripheral surface of the impeller and inserted into the inner peripheral surface of the casing with a certain clearance in order to reduce the leakage loss.

이를 막기 위해, 펌프 점검 시 펌프에 물을 공급하는 장치가 반드시 필요하다. 이렇게 펌프에 물을 공급하는 장치의 설치로 인해 많은 비용이 소요된다.To prevent this, a device for supplying water to the pump is necessary when checking the pump. The installation of a device that supplies water to the pump is expensive.

따라서, 물 공급하는 장치 없이, 무급수 상태에서 구동될 수 있는 펌프의 개발이 절실히 요구된다.Therefore, it is urgently required to develop a pump that can be driven in a non-pumped state without a water supply device.

한국등록특허(10-1317443)Korea registered patent (10-1317443)

본 발명의 목적은, 무급수 상태에서 펌프를 구동하여도, 라이너링이 소착, 변형, 파손되지 않는 펌프를 제공하는 데 있다.An object of the present invention is to provide a pump in which the liner ring is not disjointed, deformed, or damaged even when the pump is driven in a non-hydraulically operated state.

상기 목적을 달성하기 위한 무급수 구동이 가능한 펌프는,In order to achieve the above object,

케이싱과, 임펠러와, 상기 케이싱의 내주면에 삽입되고 상기 임펠러의 외주면에 삽입되는 라이너 링을 포함하는 펌프에 있어서,A pump comprising a casing, an impeller, and a liner ring inserted in an inner peripheral surface of the casing and inserted into an outer peripheral surface of the impeller,

상기 라이너링은 자기 윤활성을 가지며 고강도인 탄소-탄소 복합재로 만들어진 것을 특징으로 한다.The liner ring is characterized by being made of carbon-carbon composite material having self-lubricating property and high strength.

본 발명은 자기 윤활성을 가지며 고강도인 탄소-탄소 복합재 라이너 링을 구비한다. 따라서, 무급수 상태에서 펌프를 구동하여도, 라이너링이 소착, 변형, 파손되지 않아, 무급수 상태에서 안정적으로 구동될 수 있다. 따라서, 펌프 점검 시 펌프에 물을 공급하는 장치가 필요 없어 비용을 절감할 수 있다.The present invention provides a carbon-carbon composite liner ring having self-lubricating and high strength. Therefore, even when the pump is driven in the non-pumped state, the liner ring is not stuck, deformed, or damaged, and can be stably driven in the non-pumped state. Therefore, a device for supplying water to the pump when the pump is inspected is not needed, thereby reducing the cost.

도 1 및 도 5에 도시된 본 발명의 일 실시예에 따른 무급수 구동이 가능한 펌프(1)는, 케이싱(110), 임펠러(120), 탄소-탄소 복합재 라이너링(130)으로 구성된다.1 and 5, the pump 1 capable of being driven without any water supply comprises a casing 110, an impeller 120, and a carbon-carbon composite liner ring 130.

임펠러(120)는 축(S)의 중간에 설치된다. 축(S)은 모터축(미도시)에 연결된다.The impeller 120 is installed in the middle of the axis S. The axis S is connected to a motor shaft (not shown).

탄소-탄소 복합재 라이너링(130)은 제1라이너링(131)과 제2라이너링(132)으로 구성된다.The carbon-carbon composite liner ring 130 consists of a first liner ring 131 and a second liner ring 132.

탄소-탄소 복합재 라이너링(130)은 다음과 같이 만들어진다.The carbon-carbon composite liner ring 130 is made as follows.

탄소섬유직물들과 그 사이에 탄소섬유웹을 적층하고, 적층 방향(수직 방향)으로 니들펀칭(Needle Punching)한다. 탄소섬유직물은 탄소섬유(Cf1)들이 교차되어 만들어진다. 탄소섬유웹은 짧은(3~10cm) 탄소섬유(Cf2)들이 서로 얽혀져 만들어진다. 니들펀칭은 니들판에 배열된 니들이 탄소섬유웹을 구성하는 섬유(Cf2)를 아래로 끌고 내려가, 탄소섬유직물들을 층간 결속시키는 작업을 말한다.The carbon fiber fabrics are laminated with a carbon fiber web therebetween, and needle punching is performed in the lamination direction (vertical direction). Carbon fiber fabrics are made by crossing carbon fibers (Cf1). The carbon fiber web is made by intertwining short (3-10 cm) carbon fibers (Cf2). Needle punching refers to the operation of pulling down the fibers (Cf2) constituting the carbon fiber web and arranging the carbon fiber fabrics together.

한편, 탄소-탄소 복합재 제1라이너링(131)과 탄소-탄소 복합재 제2라이너링(132)이 마찰될 부분에, 0.1~30mm의 짧은 길이를 가진 탄소섬유(Cf3)로 구성된 탄소섬유웹을 적층하고 니들펀칭하여, 0.1~2mm의 두께를 가진 마찰면을 만든다. 이렇게 짧은 탄소섬유(Cf3)들이 균일하게 분포된 마찰면으로 인해, 탄소-탄소 복합재 제1라이너링(131)과 탄소-탄소 복합재 제2라이너링(132)이 마찰되는 부분의 자기 윤활성이 더욱 향상될 수 있다.On the other hand, a carbon fiber web composed of carbon fibers (Cf3) having a short length of 0.1 to 30 mm is attached to a portion where the first liner ring 131 and the second liner ring 132 of the carbon- Layered and needle-punched to form a friction surface having a thickness of 0.1 to 2 mm. The self-lubricating property of the portion where the carbon-carbon composite first liner ring 131 and the carbon-carbon composite second liner ring 132 are rubbed is further improved due to the frictional surface in which the short carbon fibers (Cf3) are uniformly distributed. .

제1라이너링(131)과 제2라이너링(132)의 형상대로, 층간 결속된 탄소섬유직물을 컷팅한다.The interlaminar bound carbon fiber fabric is cut in the shape of the first liner ring 131 and the second liner ring 132.

탄소섬유직물을 900~1000℃로 탄화시킨다.The carbon fiber fabric is carbonized at 900 to 1000 ° C.

탄화된 탄소섬유직물에 탄화수소가스를 침투시키고 그 탄화수소 가스를 열분해하여 탄소(C)로 밀도를 높인다.The carbonized carbon fiber fabric is impregnated with hydrocarbon gas, and the hydrocarbon gas is pyrolyzed to increase the density with carbon (C).

밀도화된 탄소섬유직물의 표면을 다이아몬드 연마기로 연마한다.The surface of the dense carbon fiber fabric is polished with a diamond grinder.

그러면, 도 5에 도시된 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분의 자기 윤활성이 향상된, 제1라이너링(131)과 제2라이너링(132)이 만들어진다.Then, the first liner ring 131 and the second liner ring 132, in which the self lubrication of the portion where the first liner ring 131 and the second liner ring 132 are to be rubbed shown in Fig. 5 are improved, are produced.

이하, 제1변형예에 따른 탄소-탄소 복합재 라이너링을 설명한다.Hereinafter, the carbon-carbon composite liner ring according to the first modification will be described.

도 6에 도시된 제1변형예에 따른 탄소-탄소 복합재 라이너링(130)은 탄소나노튜브(Cn)을 포함하며, 다음과 같이 만들어진다.The carbon-carbon composite liner ring 130 according to the first modification shown in FIG. 6 includes carbon nanotubes (Cn), and is made as follows.

탄소섬유직물들과 그 사이에 탄소섬유웹을 적층하고, 적층 방향(수직 방향)으로 니들펀칭(Needle Punching)한다.The carbon fiber fabrics are laminated with a carbon fiber web therebetween, and needle punching is performed in the lamination direction (vertical direction).

탄소섬유직물은 탄소섬유(Cf1)들이 교차되어 만들어진다.Carbon fiber fabrics are made by crossing carbon fibers (Cf1).

탄소섬유웹은 짧은(3~10cm) 탄소섬유(Cf2)들이 서로 얽혀져 만들어진다.The carbon fiber web is made by intertwining short (3-10 cm) carbon fibers (Cf2).

제1라이너링(131)과 제2라이너링(132)의 형상대로, 층간 결속된 탄소섬유직물을 컷팅한다.The interlaminar bound carbon fiber fabric is cut in the shape of the first liner ring 131 and the second liner ring 132.

제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 될 탄소섬유직물 부분에만, 탄소나노튜브(Cn)가 포함된 용액을 바르고 건조시킨다. 그러면, 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 더 강화된다.The solution containing the carbon nanotubes (Cn) is applied and dried only on the portion of the carbon fiber fabric to be the portion where the first liner ring 131 and the second liner ring 132 are to be rubbed. Then, the portion where the first liner ring 131 and the second liner ring 132 are to be rubbed is further strengthened.

탄소나노튜브(Cn)는 평균직경 1~수십nm, 평균길이가 100nm~수십㎛, 순도 140% 이상인 것이 사용된다. 탄소나노튜브(Cn)는, 탄소 6개로 이루어진 육각형들이 서로 연결되어 관 모양을 이루고 있는 물질로써, 그 강도가 철강보다 100배나 뛰어나다. 용액은 디메일 설폭사이드 용액, 디메틸 포름아마이드 용액, 디메틸 아세트아미드 용액 중 어느 하나가 사용된다.The carbon nanotubes (Cn) have an average diameter of 1 to several tens nm, an average length of 100 nm to several tens of μm, and a purity of 140% or more. Carbon nanotubes (Cn) are materials in which six hexagons are connected to each other to form a tubular shape, the strength of which is 100 times better than that of steel. The solution may be any one of a dimethyl sulfoxide solution, a dimethylformamide solution and a dimethylacetamide solution.

탄소섬유직물을 900~1000℃로 탄화시킨다.The carbon fiber fabric is carbonized at 900 to 1000 ° C.

탄화된 탄소섬유직물에 탄화수소가스를 침투시키고 그 탄화수소 가스를 열분해하여 탄소(C)로 밀도를 높인다.The carbonized carbon fiber fabric is impregnated with hydrocarbon gas, and the hydrocarbon gas is pyrolyzed to increase the density with carbon (C).

밀도화된 탄소섬유직물의 표면을 다이아몬드 연마기로 연마한다.The surface of the dense carbon fiber fabric is polished with a diamond grinder.

그러면, 도 6에 도시된 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 더 강화된, 제1라이너링(131)과 제2라이너링(132)이 만들어진다.Then, the first liner ring 131 and the second liner ring 132, in which the portions where the first liner ring 131 and the second liner ring 132 are to be rubbed, are further strengthened.

이하, 제2변형예에 따른 탄소-탄소 복합재 라이너링을 설명한다.Hereinafter, the carbon-carbon composite linering according to the second modification will be described.

도 7에 도시된 제2변형예에 따른 탄소-탄소 복합재 라이너링(130)은 부분적으로 고밀도화 되며, 다음과 같이 만들어진다.The carbon-carbon composite liner ring 130 according to the second modification shown in FIG. 7 is partially densified and made as follows.

탄소섬유직물들과 그 사이에 탄소섬유웹을 적층하고, 적층 방향(수직 방향)으로 니들펀칭(Needle Punching)한다.The carbon fiber fabrics are laminated with a carbon fiber web therebetween, and needle punching is performed in the lamination direction (vertical direction).

탄소섬유직물은 탄소섬유(Cf1)들이 교차되어 만들어진다.Carbon fiber fabrics are made by crossing carbon fibers (Cf1).

탄소섬유웹은 짧은(3~10cm) 탄소섬유(Cf2)들이 서로 얽혀져 만들어진다.The carbon fiber web is made by intertwining short (3-10 cm) carbon fibers (Cf2).

제1라이너링(131)과 제2라이너링(132)의 형상대로, 층간 결속된 탄소섬유직물을 컷팅한다.The interlaminar bound carbon fiber fabric is cut in the shape of the first liner ring 131 and the second liner ring 132.

탄소섬유직물을 900~1000℃로 탄화시킨다.The carbon fiber fabric is carbonized at 900 to 1000 ° C.

탄화된 탄소섬유직물에 탄화수소가스를 침투시키고 그 탄화수소 가스를 열분해하여 탄소(C)로 밀도를 높인다. 이때, 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 될, 탄소섬유직물 부분에 탄소를 더 침투시켜 밀도를 더 높인다. 그러면, 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 더 강화된다.The carbonized carbon fiber fabric is impregnated with hydrocarbon gas, and the hydrocarbon gas is pyrolyzed to increase the density with carbon (C). At this time, carbon is further penetrated into the portion of the carbon fiber fabric to be a portion where the first liner ring 131 and the second liner ring 132 are to be rubbed, thereby further increasing the density. Then, the portion where the first liner ring 131 and the second liner ring 132 are to be rubbed is further strengthened.

밀도화된 탄소섬유직물의 표면을 다이아몬드 연마기로 연마한다.The surface of the dense carbon fiber fabric is polished with a diamond grinder.

그러면, 도 7에 도시된 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분이 더 강화된, 제1라이너링(131)과 제2라이너링(132)이 만들어진다.Then, the first liner ring 131 and the second liner ring 132, in which the portions where the first liner ring 131 and the second liner ring 132 are to be rubbed are strengthened, are produced.

상술한 바와 같이, 제1라이너링(131)과 제2라이너링(132)은 탄소-탄소 복합재로 만들어져, 자기 윤활성을 가지며 강도가 크다.As described above, the first liner ring 131 and the second liner ring 132 are made of a carbon-carbon composite material, have self-lubricating properties, and have high strength.

또한, 제1라이너링(131)과 제2라이너링(132)이 마찰될 부분에 짧은 탄소섬유(Cf3)들이 균일하게 분포된 마찰면이 형성된다. 이로 인해, 탄소-탄소 복합재 제1라이너링(131)과 탄소-탄소 복합재 제2라이너링(132)이 마찰되는 부분의 자기 윤활성이 더욱 향상된다. 이로 인해, 무급수 상태에서 펌프를 구동시켜, 제1라이너링(131)과 제2라이너링(132)이 서로 마찰되거나, 제1라이너링(131)과 제2라이너링(132) 사이에 이물질이 끼어 갈려도, 제1라이너링(131)과 제2라이너링(132)이 소착, 변형, 파손되지 않는다.Further, a friction surface in which short carbon fibers (Cf3) are uniformly distributed is formed at a portion where the first liner ring 131 and the second liner ring 132 are to be rubbed. As a result, the self lubrication of the portion where the carbon-carbon composite first liner ring 131 and the carbon-carbon composite second liner ring 132 are rubbed is further improved. As a result, the pump is driven in a non-hydraulically operated state, so that the first liner ring 131 and the second liner ring 132 are rubbed against each other, or the foreign matter between the first liner ring 131 and the second liner ring 132 The first liner ring 131 and the second liner ring 132 are not separated, deformed, or damaged.
