Diesel generator power shortage generator maintenance, troubleshooting large load automatically shut down a total configuration 200KVA generator generator for less than 60 hours, when a load current of 120A outside the emergency generator will automatically shut down after a few hours of maintenance over the exclusion of Failure finally been restored. Symptom: Engine start where normal generator maintenance, idle properly. Together over the open peripheral load current from 0 to 120A, for about 1 minute until smoky engine speed drops down significantly. Failure Analysis: generator configured to 200KVA, carried the load current can reach 360A, 120A engine will now only move the load automatically shut down the engine power is obviously insufficient, part of the problem may supply line. Troubleshooting process: 1, the replacement of diesel generators and sediment filter core, restart the engine after correct assembly and power generation, with load currents can reach 160A and then automatically shut down; 2, open play tank dumping sewage discharge valve diesel fuel moisture content than found large, installed after the exclusion of dumping sewage water valve again to start the engine, can reach 200A negative or down; 3, open the tank drain valve completely let go of all the diesel fuel tank, found that diesel impurities, dirt more. Washed with high-pressure pump gas tank, re-fueling (with gauze filter oil timber) flush tank back and forth and let go of oil contains impurities in the oil until the release of dirt is very clear and free of impurities. And then re-join the diesel (with a gauze filter when adding diesel), restart the engine, close the load switch open, current until 340A (when all possible load) in normal operation. Fault completely ruled out. Once the "Speed", should take appropriate emergency measures in place to make diesel generator sets stalled, and then troubleshoot. ① after a cold start generators produce "Speed", release the throttle, speed remains high, it should pull the pull knob turn off the flame. First, you should check whether the oil inside the governor too sticky, causing Flyweight easy to open, adjust the speed of the loss of function. ② After a long time parked car start, "Speed", should open the fuel pump or fuel pump check the front window cover fuel adjustment lever (gear lever) end face of the cap, hand moving the lever to see if flexible, if astringent stagnation, Description levers (gear lever) and cover corrosion, or poor lubrication, lubrication should be rust. ③ If the fuel pump is the "speed" during disassembly maintenance after loading, you need to check the lever (gear lever) whether due care bending catching. If so, you should remove the correction or replacement parts. ④ checking rod (gear lever), if the rod move freely, but not automatically push back forward and explain the governor rod connecting rod disconnected power generator maintenance, inspection window should open the governor cover check excluded. ⑤ If these tests were normal Cummins generator maintenance, the fault in the governor, the governor should open the back cover, complete decomposition checks. Should be carried out after the repair is completed commissioning test bench, rest assured that after loading.
