The present invention relates to an actuator fixing device for a fuel pump for a diesel engine to improve performance of an engine and a fuel pump.
일반적으로 디젤엔진은 고장율이 적고 유지관리 비용이 저렴한 한편 엔진의 출력이 높아 산업용 발전기나 선박 및 기관차 등의 장비에 사용되고 있으며, 이러한 디젤엔진은 실린더에 흡입된 공기를 압축하고 연료를 분무상태로 분사하여 폭발시키는 기관으로 연료를 실린더에 분사하기 위하여 연료펌프가 사용된다.In general, diesel engines are used in equipment such as industrial generators, ships, and locomotives because of low failure rate and low maintenance cost, and high engine power. These diesel engines compress air sucked into cylinders and inject fuel in a spray state. A fuel pump is used to inject fuel into a cylinder with an explosive engine.
디젤엔진용 연료펌프는 크게 기계식과 전자식으로 구분되고, 여기서 기계식은 형식에 따라 (RS, RSV, RQ, RQV)로 구분되어 디젤엔진에 장착되고 있으며, 전자식은 설치방법에 따라 (stop lever, throttle lever) 방식과 부런져 블럭에 직접 부착하는 방식으로 구분된다.The fuel pump for diesel engine is largely divided into mechanical and electronic, where mechanical is divided into (RS, RSV, RQ, RQV) according to the type and mounted on the diesel engine, and electronic is (stop lever, throttle) according to the installation method. lever) and boomer block.
최근 국내 산업용 발전기나 선박 및 기관차 등에 사용되는 디젤엔진과 연료펌프는 미국 커민스사가 개발 제조한 커민스 디젤엔진과 연료펌프(Cummins fuel pump (PT))가 주종을 이루고 있으며, 상기에서 미국 커민스사의 연료펌프(PT)는 전자식의 일종으로 도면에 도시된 도 1 과 같이 연료펌프(1)에서 엔진의 연소실로 공급되는 연료량은 전자식 액츄에이터가 스로틀밸브를 미세하게 개폐하여 조절하는 방식으로 전자식 소형 액츄에이터가 연료펌프(1)의 내부에 장착되어 스로틀밸브의제어를 통해 연소실로 공급되는 연료량을 미세하게 조절한다.Recently, diesel engines and fuel pumps used in domestic industrial generators, ships, and locomotives are mainly made up by Cummins diesel engines and Cummins fuel pumps (PT) developed by Cummins. (PT) is a type of electronic, as shown in Figure 1, the amount of fuel supplied from the fuel pump 1 to the combustion chamber of the engine is controlled by the electronic actuator to finely open and close the throttle valve by the electronic small actuator fuel pump It is mounted inside (1) and finely controls the amount of fuel supplied to the combustion chamber through the control of the throttle valve.
상기에서 미국 커민스사의 연료펌프는 연료(경유)가 수용된 내부에 소형 액츄에이터가 장착되어 스로틀밸브를 작동시킴으로서 장기간이 지나면 연료에 혼합된 불순물과 이물질 및 수분에 의해 액츄에이터에 부분적으로 부식이 발생하고, 또한 이물질이 끼어 미세동작이 어렵고 제기능을 상실하는 문제점이 발생하여 액츄에이터의 교환 작업이 필요하였다.In the above, the fuel pump of Cummins of the United States operates a throttle valve by installing a small actuator inside the fuel (light oil) house, and after a long period of time, the actuator is partially corroded by impurities, foreign substances, and moisture mixed with the fuel. The foreign matter was stuck, the micro-movement was difficult, and the problem of losing its proper function occurred, so it was necessary to replace the actuator.
즉, 전기적인 자력으로 미세동작이 이루어지는 액츄에이터가 연료가 충만된 연료펌프의 내부에 장착됨에 따라 연료에 혼합된 불순물과 이물질 및 수분 등으로 인하여 동작이 미세하지 못하고 손상되는 실정으로 액츄에이터의 교환 작업에 따른 고비용과 수리기간이 소모되는 문제점이 있었다.That is, as the actuator which is operated finely by electric magnetic force is installed inside the fuel pump filled with fuel, the operation is not fine and damaged due to impurities, foreign substances and moisture mixed in the fuel. There was a problem in that the high cost and repair period is consumed.

본 고안은 연료펌프의 내부로 액츄에이터가 장착된 기존의 구조와 달리 연료펌프의 외부에 액츄에이터가 장착되어 엔진의 연소실로 공급되는 연료량을 조절함에 따라 연료에 혼합된 불순물과 이물질 및 수분 등으로 인한 액츄에이터의 오동작과 손상을 방지함으로서 연료펌프와 엔진의 성능을 향상시키는 한편 액츄에이터의 오동작과 파손으로 인한 수리비용과 작업시간이 지연되는 문제점을 상대적으로 줄이는 효과를 제공하는 것이다.The present invention, unlike the conventional structure in which the actuator is mounted inside the fuel pump, the actuator is mounted on the outside of the fuel pump to control the amount of fuel supplied to the combustion chamber of the engine, and the actuator due to impurities, foreign substances, and moisture mixed in the fuel It is possible to improve the performance of the fuel pump and the engine by preventing the malfunction and damage of the engine, and to relatively reduce the problem of delayed repair cost and working time due to the malfunction and breakdown of the actuator.
