일반적으로 급유차량에는 수분분리를 위한 필터가 설치되어 있으며, 이는 급유차량을 통한 최종 급유시 불순물의 침투에 의한 기관의 치명적 손상을 방지하기 위함이다.Generally, a filter for water separation is installed in the refueling vehicle, which is to prevent fatal damage of the engine due to infiltration of impurities during final refueling through the refueling vehicle.
특히, 유류의 최종 저장장소가 지하인 경우가 많고, 방수구조가 충분치 않은 경우 이 저장장소에 수분이 침투되어 있을 우려가 있기 때문에 급유차량의 수분분리는 필수 요소이다.In particular, the final storage location of the oil is often underground, and if the waterproof structure is not sufficient, water separation of the refueling vehicle is an essential element because there is a possibility that water may penetrate the storage location.
급유차량의 필터는 예시도면 도 1 a 에서와 같이 주유펌프와 최종 배출구인 주유호오스 사이에 설치되며, 그 구조는 도 1b 와 같다.The filter of the oil supply vehicle is installed between the oil supply pump and the oil supply hose which is the final outlet as shown in FIG. 1A, and the structure thereof is shown in FIG. 1B.
도시된 것은 1,2차 엘리먼트에 의한 것으로 하우징(1) 내의 격벽(2)에 의해 1,2 차 엘리먼트가 분리되어 있다.As shown, the primary and secondary elements are separated from the primary and secondary elements by the partition wall 2 in the housing 1.
주요부는 수분여과엘리먼트(3)인 1차 엘리먼트로서, 1차 엘리먼트의 하부로 유입된 연료가 상부로 이동되면서 비중차에 의해 수분이 여과되며, 여과된 연료는 격벽(2)의 상단을 지나 2차 엘리먼트(4)로 유입되고 2차 엘리먼트(4)에 유입된 연료가 여과된후 하단의 배출구(5)를 통해 주유되는 것이다.The main part is a primary element, which is a water filtration element (3), the water is filtered by the specific gravity difference as the fuel introduced into the lower part of the primary element is moved upwards, and the filtered fuel passes through the top of the partition (2). Fuel introduced into the primary element 4 and introduced into the secondary element 4 is filtered and then oiled through the outlet 5 at the bottom.
한편, 1차 엘리먼트가 설치되는 공간인 수분분리부(6)의 하단에는 배수구(7)가 형성되어 있어, 수분분리부(6)에 여과 되어진 물이 외부로 배출되도록 되어 있으며, 2차 엘리먼트는 여과시 수분을 응집하는 부재로 주기적인 교환이 필요한 부품이다.Meanwhile, a drain hole 7 is formed at a lower end of the water separator 6, which is a space where the primary element is installed, so that the water filtered by the water separator 6 is discharged to the outside. It is a component that needs to be replaced periodically as it is a member that aggregates moisture during filtration.
그러나, 이러한 필터가 장착되어 있다 하더라도, 이는 소량의 불순물(수분) 여과일 뿐이서 연료 자체가 불량인 경우, 즉 연료에 다량의 수분이 함유되어 필터의 여과용량을 초과한 경우에는 불량연료가 충분히 여과되지 않은 상태로 주유되는 문제점이 있었다.However, even if such a filter is installed, it is only a small amount of impurity (moisture) filtration, and if the fuel itself is defective, that is, if the fuel contains a large amount of water and exceeds the filtration capacity of the filter, the defective fuel is sufficient. There was a problem that the oil is not filtered.
이에 본 발명은 상기 문제점을 해소하기 위하여 안출된 것으로, 연료에 다량의 수분이 함유되어 필터의 수분여과능력이 미치지 못하는 경우 주유를 차단하고 작업자에게 이를 경고토록 하는 과도한 수분함량에 따른 주유차단장치를 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made in order to solve the above problems, the fuel blocking device according to the excessive moisture content to shut off the oil and warn the worker if the fuel containing a large amount of water does not meet the water filtration ability of the filter. The purpose is to provide.
이를 위한 본 발명은 수분분리부의 배수구 배수량을 수분여과엘리먼트에 의한 적정 여과량보다 적게 설정하여, 과도한 수분이 함유된 불량연료가 필터에 유입되어 여과량이 배수량을 초과하게 되면, 이에 따른 수분분리부의 수위 상승속도 증가에 의해 불량연료 유입을 판단한 것으로, 수위상승속도를 감지하기 위해 수분분리부에 수위감지센서가 설치되어 지며, 수위감지센서는 컨트롤유니트와 연결되어지고, 컨트롤유니트에는 수위상승 속도에 따른 한계치가 설정되어 있어 그 한계치를 초과하는 경우, 즉 수위상승속도가 급하게 되어지는 경우 불량연료가 주유될 우려가 있다고 판단하여 각 장치를 제어하게 되는 것이다.The present invention for this purpose is to set the drainage drainage of the water separation portion less than the proper filtration amount by the water filtration element, when the defective fuel containing excess water is introduced into the filter and the filtration amount exceeds the drainage, the water level of the water separation portion accordingly In order to detect the inflow of bad fuel by increasing the rising speed, the water level sensor is installed in the water separation section to detect the water level rising speed, the water level sensor is connected to the control unit, and the control unit according to the water level rising speed When the limit value is set and the limit value is exceeded, that is, when the speed of water rises rapidly, it is determined that there is a risk of refueling of fuel.
컨트롤유니트는 불량연료 감지시 연료차단과 동시에 경고장치를 구동시키며, 연료차단은 주유펌프로의 전원공급라인에 형성된 스위치부를 작동시켜 주유펌프로의 전원을 차단하여 연료의 공급을 정지시키는 것이고, 경고장치 구동은 경광등의점등과 경고음 방출이 일반적인 것으로, 컨트롤유니트가 상기 연료차단과 더불어 경고장치를 구동시켜 작업자에게 불량연료가 주유될 수 있음을 신속히 주의시키도록 한 것이다.The control unit operates the warning device at the same time as the fuel cutoff when detecting bad fuel, and the fuel cutoff stops the supply of fuel by cutting off the power to the fuel pump by operating the switch part formed in the power supply line of the fuel pump.

예시도면 도 2 는 본 발명에 따른 주유차단장치의 설명도로서, 본 발명은 급유차량 필터 하우징의 수분분리부(6)에 수분여과엘리먼트(3)의 여과량보다 배출량이 적은 배수구(10)가 형성되고, 이 수분분리부(6)에는 수위감지센서(12)가 설치됨과 더불어, 상기 수분분리부(6)의 수위상승속도의 한계치가 설정되어 불량연료임을 감지하는 컨트롤유니트(14)가 마련되어 그 입력단에 상기 수위감지센서(12)가 연결되고, 출력단에는 불량연료 감지시 주유중단과 동시에 경고장치가 작동되게 주유펌프(16)의 전원공급라인에 형성되어진 스위치부(18)와 주유차량에 마련되어진 경고장치(20)가 연결된 과도한 수분함량에 따른 주유차단장치이다.2 is an explanatory view of an oil lubrication blocking device according to the present invention, in which the drainage port 10 having a smaller discharge amount than the filtration amount of the water filtration element 3 is provided in the water separator 6 of the lubrication vehicle filter housing. The water separator 6 is provided with a water level detection sensor 12 and a control unit 14 for detecting that the fuel is defective by setting a limit value of the water level rising speed of the water separator 6 is provided. The water level detecting sensor 12 is connected to the input terminal, and the output terminal is connected to the switch unit 18 and the fueling vehicle formed on the power supply line of the fuel pump 16 so that a warning device is activated at the same time as the fueling stops when detecting poor fuel. The warning device 20 is provided is a fuel shutoff device according to the excessive moisture content is connected.
상술된 바와 같이 본 발명은 과도한 수분이 함유된 불량연료가 주유될 때 이를 감지하여 주유를 차단하는 장치를 제공한다.As described above, the present invention provides a device that detects when poor fuel containing excessive moisture is oiled and blocks oiling.
불량연료의 감지는 수분분리부(6)의 수위상승속도에 의하며, 수위상승속도는 결정된 수분분리부의 부피내에서 배수량과 여과량에 의해 결정되어진다.The detection of the defective fuel is based on the water level rising speed of the water separator 6, and the water level rising speed is determined by the drainage amount and the filtration amount in the determined volume of the water separating part.
즉, 수분분리부(6)의 배수구(10)는 그 배수량이 수분여과엘리먼트(3)에 의한 적정 여과량보다 적게 설정되어져 있어, 과도한 수분이 함유된 불량연료가 필터에 유입되어 여과량이 증가하게 되면 배수량을 초과하게 되어 수분분리부(6)의 수위가상승되고, 이에 의해 불량연료의 유입이 판단되어지는 것이다.That is, the drainage port 10 of the water separation section 6 is set such that the drainage amount is smaller than the appropriate filtration amount by the water filtration element 3, so that the defective fuel containing excessive moisture is introduced into the filter to increase the filtration amount. If the drainage is exceeded, the water level of the water separator 6 is increased, whereby inflow of the defective fuel is determined.
이러한 수위상승속도를 감지하기 위해 수분분리부(6)에 수위감지센서(12)가 설치되어 지며, 수위감지센서(12)는 포텐셔미터의 일종으로 수위에 따른 저항값이 달리 설정되어져 그 송출신호가 차별화 되어진 센서이다.The water level detection sensor 12 is installed in the water separator 6 to detect the rate of rising water level, and the water level detection sensor 12 is a kind of potentiometer, and the resistance value according to the water level is set differently so that the transmission signal is transmitted. It is a differentiated sensor.
이러한 수위감지센서(12)는 컨트롤유니트(14)와 연결되어지며, 컨트롤유니트(14)에는 수위상승 속도에 따른 한계치가 설정되어 있어 그 한계치를 초과하는 경우, 즉 수위상승속도가 급하게 되어지는 경우 불량연료가 주유될 우려가 있다고 판단하여 각 장치를 제어하게 되는 것이다.The water level detection sensor 12 is connected to the control unit 14, the control unit 14 is set to the limit value according to the water level rising speed, if the limit is exceeded, that is, if the water level rising speed is urgent Each device is controlled by determining that there is a risk of refueling fuel.
컨트롤유니트(14)는 불량연료 감지시 연료차단과 동시에 경고장치(20)를 구동시키며, 연료차단은 주유펌프(16)로의 전원공급라인에 형성된 스위치부(18)를 작동시켜 주유펌프(16)로의 전원을 차단하여 연료의 송압이 정지되는 것이다.The control unit 14 drives the warning device 20 at the same time as the fuel cut off when the defective fuel is detected, and the fuel cut off operates the switch 18 formed in the power supply line to the fuel pump 16 to supply the fuel pump 16. The power supply to the fuel is stopped by shutting off the power to the furnace.
이와 더불어, 주유펌프와 필터로의 연료공급라인에 솔레노이드밸브(22)를 장착하고 컨트롤유니트(14)의 출력단에 이 솔레노이드밸브(22)를 연결하여, 상기 주유펌프(16)로의 전원차단과 동시에 솔레노이드밸브(22)를 작동시켜 연료공급라인을 폐쇄하여서 주유펌프(14)가 완전히 정지되기 전까지의 연료공급 차단 응답속도를 빠르게 함도 가능하다.In addition, the solenoid valve 22 is attached to the fuel supply line to the fuel pump and the filter, and the solenoid valve 22 is connected to the output end of the control unit 14, and at the same time the power is turned off to the fuel pump 16. By closing the fuel supply line by operating the solenoid valve 22, it is possible to increase the fuel supply cutoff response speed until the fuel pump 14 is completely stopped.
한편, 경고장치(20) 구동은 경광등(24)의 점등과 스피커(26)를 통한 경고음 방출이 일반적인 것으로, 컨트롤유니트(14)가 상기 연료차단과 더불어 경고장치를 구동시켜 작업자에게 불량연료가 주유될 수 있음을 신속히 주의시키도록 한 것이다.On the other hand, the driving of the warning device 20 is the lighting of the beacon 24 and the emission of the warning sound through the speaker 26 are common. The control unit 14 drives the warning device together with the fuel cutoff to supply fuel to the worker. It is a quick reminder that it can be.
상술된 바와 같이 본 발명에 따르면, 수분이 과도하게 함유된 연료가 주유차량의 연료탱크로부터 주유될 우려가 있을때, 이를 미리 감지하여 주유를 차단시키고 작업자에게 이를 주의시킴으로써, 불량연료의 주유가 방지되는 효과가 있다.As described above, according to the present invention, when there is a risk that fuel containing excessive water is refueled from the fuel tank of the refueling vehicle, it is detected in advance to block the refueling and pay attention to the operator, thereby preventing refueling of poor fuel It works.
