South Korea's Daewoo diesel generator sets test steps
South Korea's Daewoo diesel generators need to be tested after the completion of production to ensure that the normal safety and failure of the unit. In addition, if the diesel generator set is repaired, the diesel generator set must be tested before use. This shows the importance of the test steps for diesel generator sets. So what's the test procedure for the Korean Daewoo diesel generator? Let the full power technicians give the user a detailed introduction. Test machine. The old diesel engine is carefully checked by cranking the crankshaft, pulling the flywheel, and starting the machine. The test machine is a very important step. The specific inspection steps are as follows:
1. Shake the crankshaft so that the fuel injectors are supplied with oil. If the nozzle emits a crisp sound, it indicates that the performance of the fuel injector and the plunger pair is still good; if there is no abnormal noise such as “round noise†in the wheel room, the wear of the gear is not serious.
2. Move the flywheel up and down. If there is no sound, the gap between the shaft of the crankshaft and the bearing bush is not large.
3, turn the flywheel, so that the piston near the bottom dead center, and then shake the flywheel left and right, if there is no "click" sound, indicating that the link between the shaft stem and tile wear is not serious.
4. Depressurize the cylinder and crank the crankshaft. When the decompression is removed, if the piston has large repulsion force, the flywheel rotates quickly, indicating that the cylinder, piston, and piston ring have little wear. When cranking the crankshaft, the pointer of the oil pressure gauge should not be lower than 1 or the oil marking red mark can rise quickly, and the pressure of the hand should be laborious.
5, start the machine. If it is easy to start, the smoke is colorless or light gray, and the rotation speed is stable and noiseless, indicating that the technical condition of the old diesel engine is good.
The testing of the Daewoo diesel generator set in Korea will be checked in advance if there is an abnormality in the unit, so that it can be processed as soon as possible to ensure the normal operation of the unit. Even if there is no abnormal situation, it can let you know the status of the diesel generator itself. Hope that the above introduction can bring users reference.
