Inspection Method For Diesel Generator Set Not Starting

Jul. 28, 2022

In order to successfully start the diesel generator set, it must have a high enough speed, good cylinder compression force, and timely injection of well-atomized fuel. In addition, there must be a certain temperature, so that the atomized fuel reaches a state of ignition. When the diesel generator set cannot be started, the reasons should be found from the aspects of starting work, diesel fuel supply system and compression, etc. Jiangsu Starlight Electricity Equipments Co.,Ltd. will explain to you the specific inspection method when the diesel generator set cannot be started:


1. When the diesel generator set cannot be started, first check the circuit. Press the start button and the starter motor does not move, it means the circuit is open circuit or poor contact. If only the starting gear and the flywheel ring gear collide, it means that the big and small gears are not meshed. At this time, just move the flywheel by one to several teeth. If the starter motor turns weak and the speed is low, the battery power is insufficient.


2. If the starter motor runs powerfully, the speed is normal but does not ignite, the fuel nozzle does not scream, and the exhaust pipe is smokeless, then the fuel system is faulty. Or although it can be started, it turns off after a few turns, and there is air or moisture in the fuel.


3. When the starter motor reaches the starting speed, although there is a sound of fuel injection from the nozzle, it is not easy to start, and there is a sound of air leakage. After stopping, use a screwdriver to move the flywheel. If it is easy and weak, or the resistance is small, and the flywheel has no rebound phenomenon, it means that the compression force is insufficient.


4. If the ambient temperature is too low, or the machine has been parked for too long, the oil is too thick, the resistance of the moving parts is large, the gap between the piston and the cylinder is too large, and the compression force is insufficient, etc., it is difficult to start. At this time, use hot water or steam to preheat the machine before starting it.
