Abstract
Description
본 발명은 산업용으로 사용되는 디젤엔진의 전자식 인젝션펌프(Injection Pump)에 관한 것으로, 엔진의 연소실로 공급되는 연료량을 미세하게 조절하는 액츄에이터를 인젝션펌프에 장착하여 엔진의 회전속도를 정속으로 제어할 수 있도록 하는 전자식 인젝션펌프의 액츄에이터(Actuator) 고정장치에 관한 것이다.The present invention relates to an electronic injection pump of a diesel engine used for an industrial purpose, and equipped with an injection pump equipped with an actuator for finely controlling the amount of fuel supplied to an engine combustion chamber to control the rotation speed of the engine at a constant speed. It relates to an actuator fixing device of an electronic injection pump.
디젤엔진은 가솔린엔진과는 달리 고장이 적고 유지비용이 저렴하며 엔진출력이 높아 산업용 발전기나 선박 및 기관차와 같은 장비에 많이 사용되고 있는데, 디젤기관은 실린더에 흡입된 공기를 압축하여 고온도가 되었을때 분무상의 연료를 분사해 자연 발화에 의해 점화, 폭발시키는 기관으로 연료를 분사노즐로 공급해 분사하기 위해 인젝션펌프를 사용하고 있다.Unlike gasoline engines, diesel engines are frequently used in equipment such as industrial generators, ships, and locomotives because of their low breakdown, low maintenance costs, and high engine power. An injection pump is used to inject the fuel into the injection nozzle to inject the atomized fuel to ignite and explode by spontaneous ignition.
이와같은 디젤엔진의 인젝션펌프는 기계식과 전자식으로 구분되는데, 기계식은 형식에 따라(RS, RSV, RQ, RQV)로 나눠져 시중에 공급되고 있으며 전자식은 설치방법에 따라 (stop levver, throttle lever)방식과 부런져블록에 직접 부착하는 방식으로 나눠진다.The injection pump of diesel engine is divided into mechanical type and electronic type. The mechanical type is divided into types (RS, RSV, RQ, RQV) and supplied on the market, and the electronic type is based on the installation method (stop levver, throttle lever). It is divided into the direct attachment to the and booger block.
상기 기계식 인젝션펌프는 엔진의 실린더로 공급되는 연료량을 정확히 조절하는데 한계가 있어 무부하에서 부하 운전시 회전속도의 변동이 약 5% 이상 발생하여 정속의 회전속도를 요구하는 산업용 발전기나 기타 장비에는 적합치 않아 그 해결책으로 전자식 인젝션펌프를 설치하여 사용하고 있다.The mechanical injection pump has a limitation in accurately adjusting the amount of fuel supplied to the cylinder of the engine, so that the rotational speed changes by about 5% or more when the load is operated at no load, which is not suitable for an industrial generator or other equipment requiring a constant rotational speed. The solution is to install and use an electronic injection pump.
종래 산업용 디젤엔진에 장착되는 전자식 인젝션펌프는 도면에 도시한 도 1 과 2 에서 보는 바와같이 기계식 인젝션펌프의 측면에 장착된 콘트롤장치를 떼어내고 다수의 밸브홀더(2)가 결합된 부런져블록(1)의 측면에 액츄레이터(8)가 내부에 장착된 액츄에이터 하우징(3)을 부착하여 전기적인 힘으로 작동하는 액츄에이터(8)로 엔진의 회전속도를 제어하는 방식과 또한 부런져블록(1)의 측면에 결합된 가바나커버(5)에 링크대(6)가 연결된 커버하우징(4)을 부착하고 액츄에이터(8)는 별도로 엔진에 장착하여 링크대(6)를 액츄에이터(8)의 레버(7)와 결합해 액츄에이터(8)가 레버(7)를 회전시킴으로써 링크대(6)에 의해 엔진의 회전속도를 제어하도록 설치된다.The electronic injection pump mounted on a conventional industrial diesel engine removes the control device mounted on the side of the mechanical injection pump, as shown in FIGS. 1 and 2, and a plunger block in which a plurality of valve holders 2 are combined. A method of controlling the rotational speed of the engine with an actuator 8 operated by an electric force by attaching an actuator housing 3 having an actuator 8 mounted therein to the side of 1) and also a bulge block 1 Attach the cover housing (4) connected to the link base (6) to the gabbana cover (5) coupled to the side of the actuator and the actuator (8) is attached to the engine separately to the link (6) lever (7) of the actuator (8) Actuator 8 is installed to control the rotational speed of the engine by link stage 6 by rotating lever 7.
상기 전자와 후자의 방식은 엔진의 회전속도가 정속으로 유지되나, 전자의 경우 액츄에이터가 장착된 액츄에이터 하우징을 별도로 제작하고 부런져블록의 측면에 결합된 가바나커버를 떼어내고 부착시켜야해 고비용과 작업자의 숙련된 기술이 필요하며 후자의 경우는 링크대가 연결되는 커버하우징이 가바나커버에 부착되는 한편 액츄에이터가 별도로 엔진에 장착되 링크대에 의해 동작이 이루어져 출력이 큰 액츄에이터가 요구되고 넓은 공간을 필요로 하며 고비용이 소요되는 실정이다.In the former and the latter method, the rotational speed of the engine is maintained at a constant speed, but in the former case, the actuator housing equipped with the actuator must be manufactured separately, and the cabana cover coupled to the side of the plunger block needs to be removed and attached, thereby providing high cost and In the latter case, the cover housing to which the link stage is connected is attached to the gabbana cover, while the actuator is mounted on the engine separately and operated by the link stage, requiring a large output actuator and requiring a large space and high cost. This situation is required.
이와같은 전자식 인젝션펌프 및 액츄에이터는 전량 수입에 의존하고 있어 사용중 고장이 발생하면 수리가 어렵고 수리시 숙련된 기술자와 고비용이 소요되는 불합리한 문제점이 있었다.Such electronic injection pumps and actuators depend on the total amount of imports, so if a failure occurs during use, it is difficult to repair and there is an unreasonable problem that requires a skilled technician and a high cost during the repair.
본 발명은 협소한 공간에 장착이 가능하며 구조가 간단해 작업자가 용이하게 액츄에이터를 부런져블록에 장착시킬 수 있도록 하기 위한 것으로,The present invention can be mounted in a narrow space and the structure is so that the operator can easily mount the actuator to the plunger block,
이러한 본 발명은 부런져블록에 결합된 가바나커버에 부착되도록 가바나커버에 형성된 체결홈과 일치하는 체결홈이 다수개 형성되고 연료의 분사량을 조절하는 콘트롤로드의 선상위치에 관통되는 삽입공이 형성되며 이 삽입공을 중심으로 액츄에이터가 부착되는 고정면이 상하로 턱이 지도록 형성되 다수개의 결합홈이 형성된 브라켓과,The present invention is formed with a plurality of fastening grooves matching the fastening grooves formed in the gabbana cover to be attached to the gabbana cover coupled to the plunger block and is formed an insertion hole penetrating the linear position of the control rod for adjusting the injection amount of the fuel A bracket having a plurality of coupling grooves formed on a fixing surface to which the actuator is attached to the jaw up and down around the insertion hole,
상기 브라켓의 고정면에 부착되는 액츄에이터의 작동축에 연결대가 결합되 콘트롤로드와 고정핀으로 결합시켜 엔진의 회전속도를 액츄에이터가 제어하도록 구성되는 것을 구조적 특징으로 하는 것이다.It is a structural feature that the actuator is coupled to the operating shaft of the actuator attached to the fixing surface of the bracket is coupled to the control rod and the fixing pin configured to control the rotational speed of the engine.
이러한 본 발명은 기계식 인젝션펌프의 부런져블록에서 가바나커버를 떼어내지 않고 그 측면에 삽입공이 형성된 브라켓을 부착하고 액츄에이터의 작동축과 콘트롤로드를 결합한 후 브라켓에 액츄에이터를 장착하고 최종적으로 스트로크를 조정하여 마무리되 장착이 간단하고 저비용으로 전자식 인젝션펌프의 설치를 실현할 수 있는 것이다.The present invention, without removing the gabbana cover from the plunger block of the mechanical injection pump, attaching a bracket having an insertion hole formed on the side thereof, combining the actuator's operating shaft and the control rod, and then installing the actuator on the bracket and finally adjusting the stroke.
