Description

펌핑인젝터와 일반인젝터 겸용 측정장치{PUMPING INJECTOR AND NON-PUMPING INJECTOR COMBINED MEASURING APPARATUS}Measuring device for pumping injector and general injector

펌핑인젝터는 주로 대형 버스나 트럭에 설치된 인젝터이며, 종래 일반적인 인젝터와 같이 연료를 분사하는 역할을 수행함과 아울러 연료를 고압으로 승압시키는 펌프의 역할을 겸하여 수행하도록 구성된다.The pumping injector is mainly an injector installed in a large bus or truck, and is configured to perform a role of injecting fuel like a conventional injector and also serve as a pump for boosting the fuel to a high pressure.

도 2는 본 발명의 실시 예에 따른 펌핑인젝터(20)와 일반인젝터(30) 겸용 측정장치에 의해 펌핑인젝터(20)와 일반인젝터(30)의 성능을 측정하는 구성을 도시한 도면이고, 도 3은 펌핑인젝터(20)와 일반인젝터(30) 겸용 측정장치의 실물 제품을 찍은 사진도이다.2 is a diagram showing a configuration for measuring the performance of the pumping injector 20 and the public injector 30 by the pumping injector 20 and the public injector 30 combined measuring device according to an embodiment of the present invention, FIG. 3 is a photograph of the real product of the pumping injector 20 and the general injector 30 combined measuring device.

설명에 앞서, 제1측정부(41)는 펌핑인젝터(20)의 고압 펌핑량과 리크량, 일반인젝터(30)의 리크량을 측정하게 되고, 제2측정부(61)는 펌핑인젝터(20)의 분사량, 일반인젝터(30)의 분사량을 측정하게 된다.Prior to the description, the first measurement unit 41 measures the high-pressure pumping amount and the leakage amount of the pumping injector 20 , and the leakage amount of the general injector 30 , and the second measurement unit 61 measures the pumping injector 20 ), the injection amount of the general injector 30 is measured.

제1,제2측정부(41)(61)에 의해 펌핑인젝터(20)와 일반인젝터(30)의 고압 펌핑량, 분사량, 리크량을 측정하기 위해 다수의 체크밸브(91)(92)(93)(94)(95)(96)(97)를 설치하여 연료의 흐름을 관리함으로써 측정이 가능해지는 것이다.A plurality of check valves 91, 92, ( 93), 94, 95, 96, and 97 are installed to manage the flow of fuel, so that measurement becomes possible.

펌핑량측정부(40)에 의해 펌핑인젝터(20)의 고압 펌핑량을 측정하는 구성을 보면, 저압펌프(22)에 의해 연료가 유입되어 체크밸브(93)를 통해 흘러 펌핑인젝터(20)의 저압포트로 공급된다.Looking at the configuration in which the high-pressure pumping amount of the pumping injector 20 is measured by the pumping amount measuring unit 40, fuel is introduced by the low-pressure pump 22 and flows through the check valve 93 of the pumping injector 20. It is supplied through the low pressure port.

공급된 연료는 펌핑인젝터(20)의 고압포트로 유출되어 커먼레일(100)로 공급된 후 DRV(연료압력조절밸브)의 리턴포트에 의해 체크밸브(97)(91)로 흘러 제1측정부(41)로 공급되면서 고압 펌핑량이 측정하게 된다.The supplied fuel flows out to the high-pressure port of the pumping injector 20, is supplied to the common rail 100, and then flows to the check valves 97 and 91 by the return port of the DRV (fuel pressure control valve) to the first measurement unit. As it is supplied to (41), the high-pressure pumping amount is measured.

다음으로, 리크량측정부(50)에 의해 펌핑인젝터(20)와 일반인젝터(30)의 리크량을 측정하는 구성을 설명한다.Next, a configuration for measuring the leak amount of the pumping injector 20 and the general injector 30 by the leak amount measuring unit 50 will be described.

펌핑인젝터(20)의 리크량을 측정하는 구성을 보면, 고압펌프(110)에서 유입되는 고압의 연료는 커먼레일(100)로 유입된 후 펌핑인젝터(20)의 고압포트로 공급된다.Looking at the configuration for measuring the amount of leakage of the pumping injector 20 , the high-pressure fuel flowing from the high-pressure pump 110 flows into the common rail 100 and then is supplied to the high-pressure port of the pumping injector 20 .

펌핑인젝터(20)의 고압 연료 중 일부는 분사노즐을 통해 분사되어 분사량을 측정하게 되고 일부는 저압포트를 통해 배출되며, 저압포트를 통해 배출된 연료는 체크밸브(96)(91)로 흘러 제1측정부(41)로 공급되면서 리크량을 측정하게 된다.Some of the high-pressure fuel of the pumping injector 20 is injected through the injection nozzle to measure the injection amount, and some of the fuel is discharged through the low-pressure port, and the fuel discharged through the low-pressure port flows into the check valves 96 and 91 to be removed. 1 The amount of leakage is measured while being supplied to the measuring unit 41 .

이때, 고압 펌핑량측정시 고압 연료가 흐르는 체브밸브(97)로는 누출된 연료가 흐르지 못하는 상태임에 따라 펌핑인젝터(20)의 리크량을 측정할 수 있는 것이다.At this time, when the high-pressure pumping amount is measured, the leak amount of the pumping injector 20 can be measured because the leaked fuel does not flow through the chev valve 97 through which the high-pressure fuel flows.

따라서 제1측정부(41)에 의해 펌핑인젝터(20)와 일반인젝터(30)의 리크량 측정시 체크밸브(96)(97)에 의해 누출된 연료의 흐름을 별도로 관리할 수 있어 펌핑인젝터(20)와 일반인젝터(30)의 리크량 측정이 개별적으로 이루어질 수 있는 것이다.Therefore, when the leakage amount of the pumping injector 20 and the general injector 30 is measured by the first measuring unit 41, the flow of fuel leaked by the check valves 96 and 97 can be managed separately, so that the pumping injector ( 20) and the leak amount of the general injector 30 can be measured individually.

일반인젝터(30)의 리크량을 측정하는 구성을 보면, 고압펌프(110)에서 유입되는 고압의 연료는 커먼레일(100)로 유입된 후 일반인젝터(30)로 공급된다.Looking at the configuration for measuring the leak amount of the general injector 30 , the high-pressure fuel flowing in from the high-pressure pump 110 flows into the common rail 100 and then is supplied to the general injector 30 .

일반인젝터(30)로 공급된 고압 연료의 일부는 분사노즐을 통해 분사되어 분사량을 측정하게 되고 일부는 일반인젝터(30)의 리턴포트를 통해 배출된 후 체크밸브(92)로 흘러 제1측정부(41)로 공급되면서 리크량을 측정하게 된다.Part of the high-pressure fuel supplied to the general injector 30 is injected through the injection nozzle to measure the injection amount, and a part is discharged through the return port of the general injector 30 and flows to the check valve 92 to the first measurement unit As it is supplied to (41), the amount of leakage is measured.

다음으로 분사량측정부(60)에 의해 펌핑인젝터(20)와 일반인젝터(30)의 분사량을 측정하는 구성을 설명한다.Next, a configuration for measuring the injection amount of the pumping injector 20 and the general injector 30 by the injection amount measuring unit 60 will be described.

펌핑인젝터(20)의 분사량을 측정하는 구성을 설명하면, 고압펌프(110)에서 유입되는 고압의 연료는 커먼레일(100)로 유입된 후 펌핑인젝터(20)의 고압포트로 공급된다.When describing the configuration for measuring the injection amount of the pumping injector 20 , the high-pressure fuel flowing in from the high-pressure pump 110 flows into the common rail 100 and then is supplied to the high-pressure port of the pumping injector 20 .

펌핑인젝터(20)의 고압 연료는 분사노즐을 통해 분사되어 체크밸브(94)로 흘러 제2측정부(61)로 공급되면서 분사량을 측정하게 된다.The high-pressure fuel of the pumping injector 20 is injected through the injection nozzle, flows into the check valve 94 , and is supplied to the second measurement unit 61 to measure the injection amount.

일반인젝터(30)의 분사량을 측정하는 구성을 보면, 고압펌프(110)에서 유입되는 고압의 연료는 커먼레일(100)로 유입된 후 일반인젝터(30)로 공급된다.Looking at the configuration for measuring the injection amount of the general injector 30 , the high-pressure fuel flowing in from the high-pressure pump 110 flows into the common rail 100 and then is supplied to the general injector 30 .

일반인젝터(30)로 공급된 고압 연료는 분사노즐을 통해 분사되어 체크밸브(95)로 흘러 제2측정부(61)로 공급되면서 분사량을 측정하게 된다.The high-pressure fuel supplied to the general injector 30 is injected through the injection nozzle, flows into the check valve 95 , and is supplied to the second measurement unit 61 to measure the injection amount.

이때, 일반인젝터(30)에서 분사되어 흐르는 연료는 펌핑인젝터(20)에서 분사되어 흐르는 체브밸브(94)를 통해서는 흘러갈 수 없는 상태임에 따라 일반인젝터(30)의 분사량을 측정하게 되며, 펌핌인젝터 역시 동일한 구성으로 분사량 측정이 이루어지는 것임에 따라 제2측정부(61)에 의해 펌핑인젝터(20)와 일반인젝터(30)의 분사량 측정이 개별적으로 이루어질 수 있는 것이다.At this time, as the fuel injected and flowing from the general injector 30 cannot flow through the Cheve valve 94 injected from the pumping injector 20, the injection amount of the general injector 30 is measured, Since the pumping injector also has the same configuration and the injection amount is measured, the injection amount of the pumping injector 20 and the general injector 30 can be individually measured by the second measuring unit 61 .

다시 도 1을 참조하면, 상기 분사량확인부(70)는 제어패널(10)에 의해 제어되어 펌핑인젝터(20)와 일반인젝터(30)의 분사량을 측정하는 과정에서 실제 분사가 이루어지는 것을 시각적으로 확인할 수 있도록 설치된 비커에 연료가 분사되는 것을 보여주게 된다.Referring back to FIG. 1 , the injection amount checking unit 70 is controlled by the control panel 10 to visually confirm that the actual injection is made in the process of measuring the injection amounts of the pumping injector 20 and the general injector 30 . It will show that the fuel is injected into the beaker installed so that

펌핑인젝터(20)와 일반인젝터(30)의 분사량 측정시 제어패널(10)에서는 분사가 이루어지는 것으로 측정되는 상태에서 분사량확인부(70)를 통해서는 실제 분사가 이루어지지 않는 상태일 수 있으며, 이는 제어패널(10)의 오작동으로 인한 오류일 수 있다.When the injection amount of the pumping injector 20 and the general injector 30 is measured, the control panel 10 may be in a state in which the actual injection is not made through the injection amount check unit 70 in a state where the injection is measured, which is It may be an error due to a malfunction of the control panel 10 .

즉, 제어패널(10)에 의한 분사량 측정시 실제 분사가 이루어지는 것을 분사량확인부(70)를 통해 작업자가 눈으로 확인하면서 분사량 측정이 정확하게 이루어지고 있는 지를 판단할 수 있는 것이다.That is, when the injection amount is measured by the control panel 10 , it is possible to determine whether the injection amount is accurately measured while the operator visually confirms that the actual injection is made through the injection amount check unit 70 .

상기 검사내역관리부(80)는 펌핑인젝터(20)와 일반인젝터(30)에 구비된 QR코드를 인식하여 해당 제품에 대한 측정데이터를 제어패널(10)의 데이터베이스에 저장하게 되며, 검사내역관리부(80)를 통해 인젝터의 QR코드를 인식하게 되면 이전에 측정한 내역을 작업자가 확인할 수 있도록 제공하게 된다.The inspection history management unit 80 recognizes the QR code provided in the pumping injector 20 and the general injector 30 and stores the measurement data for the corresponding product in the database of the control panel 10, and the inspection history management unit ( 80), when the injector's QR code is recognized, the previously measured details are provided for the operator to check.

즉, 이전 측정내역을 확인함으로써 작업자가 해당 인젝터의 수리내역도 파악할 수 있으며, 현재 측정데이터도 함께 저장함으로써 차후의 측정시 이를 활용할 수 있게 되는 것이다.That is, by checking the previous measurement history, the operator can also grasp the repair history of the injector, and by storing the current measurement data together, it can be utilized for subsequent measurements.
