[산업상의 이용분야][Industrial use]

본 고안의 수냉기관의 물펌프에 관한 것으로서, 보다 상세하게는 운전중에 미케니컬실의 밀봉습동면으로 이물질의 침투를 방지하는 물펌프용 미케니컬실에 관한 것이다.The present invention relates to a water pump of a water-cooled engine of the present invention, and more particularly, to a mechanical chamber for a water pump that prevents foreign matter from penetrating into the sealing sliding surface of the mechanical chamber during operation.

[종래기술][Private Technology]

냉각계통은 기관을 냉각하여 기관의 과열을 방지하고, 또 적당한 온도로 유지하여 기관의 성능을 유지케 하는 장치이며, 냉각매체에 따라 수냉식과, 공냉식이 있다.The cooling system is a device that cools the engine to prevent overheating of the engine, and maintains the engine performance by maintaining the engine at an appropriate temperature. There are water cooling and air cooling depending on the cooling medium.

이 수냉식은 물의 순환방식에 따라 자연 순환식과 강제 순환식이 있으나, 자연 순환식은 냉각의 신뢰성이 부족하므로 대부분 강제 순환식이 사용된다.This water-cooled type has a natural circulation type and a forced circulation type according to the water circulation method, but the natural circulation type is mostly used due to the lack of cooling reliability.

강제 순환식은 실린더 블럭과 실린더 헤드에 마련된 물재킷 안에 냉각수를 순환시켜 냉각작용을 하도록 한 것이며, 그 주요부는 레디에이터와, 물펌프, 냉각 팬, 수온 조절기등으로 구성되어 있다.Forced circulation type is to circulate the cooling water in the water jacket provided in the cylinder block and the cylinder head to the cooling action, the main part is composed of a radiator, a water pump, a cooling fan, a water temperature regulator.

일반적으로 물펌프는 냉각수를 공급하는 펌프실과, 펌프실에서 누수된 냉각수가 외부로 유출되도록 하기 위하여 일시적으로 경유하는 누설실을 포함하고 있다.In general, the water pump includes a pump chamber for supplying cooling water, and a leakage chamber temporarily passing through to allow the cooling water leaked from the pump chamber to flow out.

이 누설실과 펌프실 사이에는 냉각수의 누수를 방지하기 위하여, 미케니컬실을 내장하고 있다.A mechanical chamber is built between the leak chamber and the pump chamber to prevent leakage of cooling water.

제4도는 이러한 종래기술에 따른 물펌프의 미케니컬실의 단면도로서, 베어링샤프트(미도시)에 강제끼움 결합되어 함께 회전하는 회전부(52)와, 펌프바디에 고정된 고정부(54)를 포함한다.4 is a cross-sectional view of the mechanical chamber of the water pump according to the prior art, and includes a rotary part 52 which is forcedly coupled to a bearing shaft (not shown) and rotates together, and a fixing part 54 fixed to the pump body. do.

이 회전부(52)와, 고정부(54) 사이에는 회전부(52) 측의 메이팅링(mating ring)(56)과, 고정부(54) 측의 실링(seal ring)(58)이 제공되어 있다.A mating ring 56 on the rotating part 52 side and a seal ring 58 on the fixing part 54 side are provided between the rotating part 52 and the fixing part 54. .

이 메이팅링(56)과, 실링(58) 사이는 펌프실에서 누설실로 누수되는 냉각수에 의하여 밀봉습동면(60)를 형성하게 된다.The mating ring 56 and the seal 58 form a sealing sliding surface 60 by the cooling water leaked from the pump chamber to the leak chamber.

이 밀봉습동면(60)은 냉각수에 포함된 이물질이 유입될 수 있도록 펌프실의 냉각수에 노출되어 있다.The sealed sliding surface 60 is exposed to the cooling water of the pump chamber so that foreign matters contained in the cooling water can flow.

한편, 물펌프의 토출압에 의하여 방열기로 부터 회로내로 유동되는 냉각수에는 초기 기관의 조립시에 미세척된 미세한 입자의 주물사나, 금속칩 등, 그리고 사용중에 발생되는 마모된 금속과, 녹 등이 다량 포함되어 있다.On the other hand, the cooling water flowing from the radiator into the circuit by the discharge pressure of the water pump contains the casting sand of the fine particles, metal chips, and the like, which are generated during the assembly of the initial engine, and the worn metal and rust generated during use. Large amounts are included.

상기와같이 구성된 물펌프용 미케니컬실에 있어서, 이 밀봉습동면(60)은 회전부(52)와 고정부(54)가 밀봉습동되어서 원활하게 회전할 수 있도록 냉각수에 의하여 윤활작용된다.In the mechanical chamber for a water pump configured as described above, the sealing sliding surface 60 is lubricated by the cooling water so that the rotating part 52 and the fixing part 54 can be sealed and slide smoothly.

그러므로 이물질을 함유한 냉각수가 물펌프의 펌프실을 통과할 때, 미케니컬실의 회전부(52)와 고정부(54)가 서로 밀착된 밀봉습동면(60)으로 이물질이 유입이 된다.Therefore, when the coolant containing the foreign matter passes through the pump chamber of the water pump, the foreign matter is introduced into the sealing sliding surface 60 in which the rotating part 52 and the fixing part 54 of the mechanical chamber are in close contact with each other.

[본 고안이 해결하려는 문제점][Problems to Be Solved by the Invention]

밀봉습동면에 이물질의 유입으로 실링의 이상마모, 편마모, 면거칠어짐 등을 유발시키게 되고, 다량의 냉각수를 누설실로 누설시켜, 외기로 누설시키기 때문에, 물펌프의 수명 단축과, 기관의 신뢰성 저하를 발생시키는 문제점이 있다.Inflow of foreign matter into the sealing sliding surface causes abnormal abrasion, uneven wear and surface roughness of the sealing, and leaks a large amount of coolant into the leak chamber and leaks it to the outside air, which shortens the life of the water pump and decreases the reliability of the engine. There is a problem that generates.

이를 실현하기 위하여, 본 고안은 베어링샤프트에 강제끼움 결합된 회전부와, 펌프바디에 고정된 고정부를 포함하는 물펌프용 미케니컬실에 있어서, 회전부는 밀봉습동면을 이물질로 부터 최대한 차단, 보호할 수 있는 연장부를 갖는 슬리이브를 더욱 포함하여 이루어짐을 특징으로 하는 물펌프용 미케니컬실이다.In order to realize this, the present invention is a mechanical chamber for a water pump comprising a rotary part forcibly coupled to the bearing shaft and a fixed part fixed to the pump body, the rotary part is to block and protect the sealing sliding surface from foreign matter as much as possible It is a mechanical chamber for a water pump, characterized in that further comprises a sleeve having an extension that can be.

상기 슬리이브의 연장부에는 이물질의 유입을 최소로 차단하고, 윤활용의 냉각수는 유입될 수 있도록 복수개의 냉각용홀을 포함하여 이루어짐을 특징으로 한다.The extension portion of the sleeve to minimize the inflow of foreign matters, characterized in that the cooling water for lubrication comprises a plurality of cooling holes to be introduced.

[작용][Action]

베어링샤프트가 회전하여 펌프실의 냉각수를 기관으로 공급함에 있어서, 회전부와 고정부로 구성된 미케니컬실은 펌프실의 냉각수가 누설실로 유출되는 것을 차단한다.When the bearing shaft rotates to supply the cooling water of the pump chamber to the engine, the mechanical chamber composed of the rotating portion and the fixed portion prevents the cooling water of the pump chamber from leaking into the leak chamber.

이 회전부의 슬리이브는 냉각수에 포함된 이물질이 미케니컬실에 내장된 밀봉습동면으로 유입되는 것을 최소화한다.The sleeve's sleeve minimizes the inflow of foreign matter contained in the coolant into the sealing sliding surface embedded in the mechanical chamber.
