一种电控高压共轨系统密封性检测装置
摘要：
本发明属于柴油机技术领域，涉及一种电控高压共轨系统密封性检测装置。涉及的一种电控高压共轨系统密封性检测装置具有与共轨柴油机分离设置的共轨喷油泵；对应共轨喷油泵设置有用以驱动其动作的电机；共轨喷油泵的低压输送泵进口通过燃油管Ⅲ连通油水分离器；油水分离器的进口通过燃油管Ⅴ与连通油桶；共轨喷油泵的低压输送泵出口通过燃油管Ⅰ与燃油滤清器的燃油进口连接；所述燃油滤清器的燃油出口通过燃油管Ⅱ与共轨喷油泵的燃油进口连接；共轨喷油泵的高压燃油出口通过高压油管与电控高压共轨系统连接；共轨喷油泵的燃油回油孔通过燃油管Ⅳ与油桶连通。本发明保证了共轨柴油机在试验时可靠性；提高了工作效率。
摘要（英）：

The invention belongs to the technical field of diesel engines and relates to a sealing detection device for an electronically-controlled high pressure common rail system. The sealing detection device comprises a common rail fuel injection pump separate from a common rail diesel engine; a motor for driving the common rail fuel injection pump to act is arranged in correspondence with the common rail fuel injection pump; an inlet of an oil-water separator is communicated with a fuel barrel through a fuel pipe V; a low pressure delivery pump outlet of the common rail fuel injection pump is connected with a fuel inlet of a fuel filter through a fuel pipe I; a fuel outlet of the fuel filter is connected with a fuel inlet of the common rail fuel injection pump; a high pressure fuel outlet of the common rail fuel injection pump is connected with an electronically-controlled high pressure common rail system through a high pressure fuel pipe; a fuel return hole of the common rail fuel injection pump is connected with the electronically-controlled high pressure common rail system through a high pressure fuel pipe; a fuel return hole of the common rail fuel injection pump is communicated with the fuel barrel through fuel pipe IV. The sealing detection device ensures test reliability of a common rail diesel engine, and working efficiency is improved.
