Abstract 【Abstract】Anyang Iron and Steel Group 2800m 3 The emergency diesel engine pump set of circulating water pump station of blast furnace adopts Volvo penta tad1642ge industrial diesel engine. The engine adopts ems2 + Siemens cpu224cn + Schneider 67160 comprehensive control. Ems2 is used for basic engine control such as common rail fuel injection and timing judgment. Siemens cpu224cn is used for on-site control cabinet control, and Schneider 67160 is used for information display and control in the main control room. When the engine has a fault, due to the complex control relationship and the lack of corresponding data and debugging tools, it is easy to fall into a dilemma about the fault. The engine could not be started once due to the short circuit of CIU water inflow. After replacing the CIU, the starting difficulty fault occurred intermittently. Finally, it was analyzed that it was the cause of the speed sensor, and the problem was solved after maintenance, which can be used as a reference for the fault judgment and maintenance of Volvo 16L series diesel engine.
