Never leave home line up knowledge, excavator parts generator fault how to solve?

Engineering after return to work, because of the holiday, excavator spare parking for a long time, some teachers neglect the excavator accessories maintenance detection. Excavator generator fails, drivers cannot be started, the influence time limit for a project, project will be affected.

drivers common aderse alarm, charging schedule don't turn, can't without electricity, and generators are involved. Share with you today is generator troubleshooting methods and generator maintenance matters needing attention.

charging bad alarm 1, check the generator belt firmness. 2, check the battery electrolyte, voltage and line. 3, check the generator output voltage is normal.

schedule did not turn 1, check the wiring behind the clock circuit or short circuit. 2, check the generator at the back of the connection is broken. P0627 alarm alarm content: bad start motor 1, check the line, see if there are any more electric starter relay, such as the blown fuse, need to change. 2, after replacing the fuse, start the motor still no response, line normally, check whether start the motor fault. 3, check the start motor charging voltage is normal, such as abnormal voltage, need to replace the generator.

drivers started difficult judgment: generator built-in regulator failure. Screening methods: can use multimeter to check the battery voltage, check drivers to start the moment respectively, after start-up, engine didn't stop running voltage, such as in to work after a period of time since the start of the value of voltage is always the same, show that the generator has been on the accumulator. Note: due to long-term the battery charging, the battery will lead to damage to lack of electrolyte, the battery is low, the machine start difficult. Solution: replace the generator and battery. Emergency start generator does not work, can use spanner nipple line to start the generators at both ends.

generator maintenance note 1, regularly check the excavator parts generator belt looseness, if too loose will cause the belt creep, even generator does not turn, too tight will accelerate on the generator, fan and water pump bearing wear. 2, check whether generator bearing oil shortage or poor lubrication, if can lead to poor lubrication between the bearing wear, causing the generator overheating, unstable voltage and current. 3, keep the generator looks clean, no dust dirt deposition, if will affect the heat dissipation, increasing the turbine burn rate. 4, check the generator related fastener tighten situation, excavator attachments fasteners if loose or fall off, could lead to unstable voltage, current, and even cause the instrument damage to electronic components. 【 Excavator accessories manufacturers] Some information from the Internet, and strive to secure timely, accurate, aims to deliver more information, does not represent the views or responsibility for their authenticity.
