How to Disassemble The Main Maintenance Parts of Diesel Generator Sets?

Do you know how to disassemble the main maintenance parts of diesel generator sets? First, remove the external wiring of the generator and make a mark. For example, for an asynchronous motor, make the mark corresponding to the three-phase power line. For a DC motor, make the shunt winding, armature winding, etc. and external connect the corresponding marks, and then loosen the foot screws to separate the motor from the transmission mechanism. Use special tools to disassemble the pulley or coupling on the motor shaft. Sometimes you need to add some kerosene to the gap between the motor shaft of the pulley to make it penetrate and lubricate, which is easy to disassemble. Some shafts and wheels fit tightly. Yes, the wheel needs to be heated quickly (while covering the shaft with a damp cloth) before the wheel can be removed.

For motors equipped with rolling bearings, first remove the bearing cover, then loosen the fastening screws of the end cover, and mark the joints between the end cover and the housing shell (the marks on the front and rear end covers should not be Same), screw the removed screws to fasten the end cover into the two specially set screw holes on the motor end cover, and push the end cover out. For motors without such screw holes, you can only use chisel and hit the seam between the end cover and the base with a hammer, and remove the end cover from the base. If the end cover is heavy, use a lifting device to lift the end cover and gradually remove it. When disassembling a motor with a brush, the brush should be taken out of the brush holder. When removing the DC motor, mark the position of the neutral wire of the brush.

When pulling out the rotor, you must be careful not to damage the stator coil. If the rotor is not heavy, you can pull it out by hand. If the weight is heavier, you should use lifting equipment to lift it out. First, set the diesel generator set at both ends of the rotor shaft. Reuse the steel wire rope to hang the rotor with the lifting equipment, slowly move it out, take care to prevent the coil from being damaged, and then put a steel pipe on one end of the shaft. In order to prevent the steel pipe from scratching the journal, the steel pipe can be lined with a layer of thick cardboard to continue. Move the rotor out gradually. When the center of gravity of the rotor has moved to the outside of the stator, put a bracket under the end of the rotor shaft and put the steel wire rope in the middle of the rotor to draw out all the rotor.
