Description
본 발명은 디젤엔진의 연료여과기에 관한 것으로, 특히 연료여과기의 일측에 물이나 기타 불순물을 용이하게 확인할 수 있도록 투명튜브가 설치된 디젤엔진의 연료여과기 구조에 관한 것이다.The present invention relates to a fuel filter of a diesel engine, and more particularly, to a fuel filter structure of a diesel engine in which a transparent tube is installed to easily identify water or other impurities on one side of the fuel filter.
일반적으로, 디젤엔진에서 연료장치는 도 1에서 보는 바와 같이, 연료탱크(11)속의 연료를 피드펌프(12)를 통하여 빨아올리고 연료여과기(1)를 통하여 걸러진 여료를 인젝션펌프(14)를 통해 고압으로 바뀌어져 인젝션파이프를 거쳐 엔진의 운전상태에 따라 연료의 분사량 및 분사시간을 제어하여 인젝션 노즐(15)에서 연료 실내로 분사되는 한편, 인젝션펌프(14)내에서 노즐(15)로 압송되지 않았던 연료 및 노즐(15)의 니들의 윤활한 연료는 각각 리턴파이프를 경유하여 연료탱크(11)로 되돌아가도록 된다.In general, in the diesel engine, as shown in FIG. 1, the fuel device sucks up the fuel in the fuel tank 11 through the feed pump 12 and filters the fuel filtered through the fuel filter 1 through the injection pump 14. It is changed to high pressure to control the injection amount and injection time of the fuel in accordance with the operation state of the engine via the injection pipe to be injected from the injection nozzle 15 into the fuel chamber, while not injected into the nozzle 15 in the injection pump 14 The unlubricated fuel and the lubricated fuel of the needle of the nozzle 15 are returned to the fuel tank 11 via the return pipe, respectively.
여기서, 상기 연료를 여과하여 먼지나 수분등을 제거하는 연료여과기에 대해서 살펴보면, 상하로 분리될 수 있는 원통형의 몸체, 이 몸체의 내부에는 연료속의 수분을 제거하기 위한 연료수분분리기(sedimenter)가 구비되며, 이 연료수분분리기 내부에는 수위를 알리는 수위센서가 부착되어 진다.Here, looking at the fuel filter for filtering the fuel to remove dust or water, the cylindrical body that can be separated up and down, the interior of the body is provided with a fuel moisture separator (sedimenter) for removing the water in the fuel The fuel water separator is equipped with a water level sensor to indicate the water level.
한편, 상기 몸체내부에 설치되는 필터엘리먼트에는 여과지, 여과포 등으로 구성되며, 일반적으로 여과지가 많이 사용되고 있다.On the other hand, the filter element installed in the body is composed of filter paper, filter cloth, and the like, generally filter paper is used.
이에 따라, 오버플로밸브는 연료피드펌프에서의 송출압력이 규정에 달했을때 열리며, 여분의 연료가 탱크로 되돌아가도록 되어 있고, 프렉시블파이프의 접속부 및 필터 등에 무리가 가해지는 것을 방지하고 있다. 또한 연료중에 공기가 혼입한 경우에도 오버플로밸브에서 연료와 함께 공기가 배출되게 된다.As a result, the overflow valve opens when the discharge pressure from the fuel feed pump reaches the prescribed value, and the excess fuel is returned to the tank to prevent excessive pressure from being connected to the flexible pipe connection part and the filter. . In addition, even when air is mixed in the fuel, the air is discharged together with the fuel from the overflow valve.
그러나, 상기 연료여과기의 내부에서 연료를 여과하는 도중에 각종 불순물이 걸러짐에 따라 연료여과기의 성능이 저하되어 연료여과기를 청소하여 다시 사용하게 되는데, 이때 청소시기를 용이하게 알 수 없기 때문에 그 정비가 곤란한 문제점이 있었다.However, as various impurities are filtered out while the fuel is filtered inside the fuel filter, the performance of the fuel filter decreases, and the fuel filter is cleaned and used again. There was a difficult problem.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 원통형의 몸체 외측에 유도관이 형성되고, 이 유도관과 일측이 결합되는 투명튜브가 삽입되며, 이 투명튜브의 다른 일측은 하부에서 연장성형된 유입관과 결합되어, 상기 투명튜브를 통해 정비시기를 용이하게 알 수 있도록 디젤엔진의 연료여과기 구조를 제공하는데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, the induction tube is formed on the outer side of the cylindrical body, the transparent tube is coupled to one side of the induction tube, the other side of the transparent tube at the bottom The purpose of the present invention is to provide a fuel filter structure of a diesel engine, which is combined with an extended inlet tube so that maintenance time can be easily known through the transparent tube.
