Description

차량용 워터펌프 임펠러{Water pump impeller for automobile}[0001] The present invention relates to a water pump impeller for automobile,

본 발명은 차량용 워터펌프 임펠러에 대한 것으로서, 더욱 상세하게는 임펠러 배면부의 압력을 높여서 씰의 누수를 방지할 수 있고 씰부의 유체 흐름을 빠르게 만들어 씰부의 온도 상승을 방지하여 씰의 내구성을 높일 수 있는 차량용 워터펌프 임펠러에 대한 것이다.The present invention relates to a water pump impeller for a vehicle, and more particularly, to a water pump impeller capable of preventing leakage of a seal by increasing the pressure of a back surface of an impeller and increasing a fluid flow of the seal part to prevent an increase in temperature of the seal part, For a water pump impeller for a vehicle.

차량용 워터펌프 임펠러는 냉각수를 순환시키는 역할을 한다. 이때 종래의 임펠러는 모두 상면부에만 베인이 형성되어 있다. 그래서 임펠러가 정지 상태에서 갑자기 동작시 상면부의 베인을 따라 냉각수가 배출되므로 임펠러의 하면부에서 상면부로 유체가 공급되어 임펠러 하면부에 압력이 갑자기 낮아진다. 그러면 씰의 압력이 저감되어 누수가 발생한다는 문제점이 있었다.The water pump impeller of the vehicle serves to circulate the cooling water. At this time, the vane is formed only on the upper surface portion of the conventional impeller. Therefore, when the impeller suddenly operates in the stopped state, the cooling water is discharged along the vane on the upper surface portion, so that the fluid is supplied from the lower portion to the upper portion of the impeller, and the pressure suddenly decreases on the impeller bottom portion. There is a problem in that the pressure of the seal is reduced and leakage occurs.

등록특허 제10-0633868호(등록일자 2006년 10월 4일)Registered Patent No. 10-0633868 (Date of Registration October 4, 2006) 공개특허 제2002-0019264호(공개일자 2002년 3월 12일)Published Japanese Patent Application No. 2002-0019264 (published on March 12, 2002)

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 임펠러 배면부의 압력 저감을 감소시켜 씰에서 누수 되는 것을 방지할 수 있고 씰부에서 유체의 흐름을 빠르게 만들어 온도상승을 방지하여 씰의 내구성을 높일 수 있는 차량용 워터펌프 임펠러를 제공하는 것을 목적으로 한다.The present invention is intended to solve the above problems. It is an object of the present invention to provide a water pump impeller for a vehicle that can reduce the pressure reduction of the impeller back surface portion to prevent leakage from the seal and increase the durability of the seal by preventing the temperature from rising due to rapid flow of the fluid in the seal portion do.

본 발명에 따른 차량용 워터펌프 임펠러는 원판의 상면부에 베인이 형성된 임펠러에 있어서, 상기 원판의 배면부에 복수의 돌기가 더 형성된다.A water pump impeller for a vehicle according to the present invention is characterized in that a vane is formed on an upper surface of a disk, and a plurality of protrusions are further formed on a rear surface of the disk.

또한, 상기의 차량용 워터펌프 임펠러에 있어서, 상기 돌기는 베인과 반대 방향으로 형성된 것이 바람직하다.In the above-described water pump impeller for a vehicle, it is preferable that the projection is formed in a direction opposite to the vane.

본 발명에 의하면 임펠러의 원판의 배면부에 돌기가 상면부에 형성된 베인과 반대 방향으로 형성되어 있으므로 임펠러가 회전하면 원판의 하면부로 유체가 유입된다. 그래서 원판의 하면부의 압력이 올라가서 하면부의 압력저하를 방지하여 씰을 통하여 누수되는 것을 방지할 수 있다.According to the present invention, since the protrusion is formed on the back surface of the disc of the impeller in a direction opposite to the vane formed on the upper surface, the fluid flows into the lower surface of the disc when the impeller rotates. Thus, the pressure of the lower surface of the disk rises, thereby preventing the lowering of the pressure on the lower surface and preventing the leakage through the seal.

도 1 내지 도 7을 참조하여 본 발명에 따른 임펠러의 일 실시예를 설명한다. 본 발명에 따른 임펠러(10)는 원판(11)의 상면부에 베인(13)이 형성된다. 그리고 원판(11)의 하면부에 복수의 돌기(15)가 형성된다. 이때 돌기(15)는 베인(13)과 반대 방향으로 형성된다.1 to 7, an embodiment of an impeller according to the present invention will be described. In the impeller 10 according to the present invention, a vane 13 is formed on the upper surface of the disk 11. And a plurality of protrusions 15 are formed on the lower surface of the disc 11. At this time, the projection 15 is formed in a direction opposite to the vane 13.

종래의 임펠러(10)의 경우 상면부에 베인(13)만 형성되어 있다. 그래서 임펠러(10)가 회전하면 냉각수가 베인(13)을 따라 배출된다. 그러면 임펠러(10)의 하면부에 냉각수도 함께 동일한 방향으로 순환되므로 임펠러(10) 하면부의 압력이 저감된다. 그러면 씰(20)의 씰링 능력이 감소되어 씰(20)을 통하여 누수된다는 문제점이 발생한다.In the case of the conventional impeller 10, only the vane 13 is formed on the upper surface portion. When the impeller 10 rotates, the cooling water is discharged along the vane 13. Since the cooling water also circulates in the same direction on the lower surface of the impeller 10, the pressure of the lower surface of the impeller 10 is reduced. This causes a problem that the sealing ability of the seal 20 is reduced and leaked through the seal 20.

본 발명의 경우 임펠러(10)의 하면부에 돌기(15)가 베인(13)과 반대방향으로 형성된다. 이 경우 임펠러(10)가 회전하면 상면부의 베인(13)을 통하여 냉각수가 화살표 1과 같이 배출되는 반면 하면부의 돌기(13)를 통하여 배출되는 냉각수의 일부가 화살표 3과 같이 유입된다. 그러므로 임펠러(10)의 하면부의 압력이 상승된다. 따라서 씰(20)을 통하여 누수가 발생되는 것을 방지시킬 수 있다.In the case of the present invention, the projections 15 are formed on the lower surface of the impeller 10 in the direction opposite to the vane 13. [ In this case, when the impeller 10 rotates, the cooling water is discharged as shown by the arrow 1 through the vane 13 on the upper surface portion, while a part of the cooling water discharged through the lower surface projection 13 flows as shown by the arrow 3. Therefore, the pressure of the lower surface of the impeller 10 is raised. Therefore, leakage of water through the seal (20) can be prevented.

또한, 돌기(12) 때문에 유체가 임펠러(10)의 하면부로 공급되기 때문에 임펠러(10)의 하면부의 씰부에서 유체의 흐름이 빨라진다. 그러면 씰(20)의 온도가 상승하는 것을 방지할 수 있어서 씰(20)의 내구성을 향상시킬 수 있다.Also, since the fluid is supplied to the lower surface of the impeller 10 due to the protrusion 12, the flow of fluid through the seal portion of the lower surface of the impeller 10 is accelerated. Thus, the temperature of the seal 20 can be prevented from rising, and the durability of the seal 20 can be improved.
