Disassembly and assembly of Fengjun 5 generator

How do you remove a bearing housing from a generator?

On the opposite-drive-end side, lift the top part of the bearing housing until it can be moved in an axial line over the bearing liner without touching it, and then move it out. On the DE side lift the housing out and over the top of the generator.

What should I do if my generator fails?

Report any damage to the transportation company and Kato Engineering. If the generator is received during cold weather, reduce condensation on cold surfaces and failure due to wet windings by allowing the generator to reach room temperature before removing the protective packing. Unpack the generator carefully to avoid scratching painted surfaces.

What should I do if my generator doesn't have a prelube system?

If the generator does not have a prelube system, remove the access glass or top vent and pour oil into bearing prior to rotating the shaft. If it is not possible to rotate the generator separately, flush the bearings with an anti-rust preservative using one of the bearing preservation procedures.

How do you shut down a generator in parallel?

To shut down the generator operating in parallel, gradually reduce the kW load by using the governor to reduce speed. When kW load and line current approach 0, open the generator circuit breaker. Operate the generator unloaded for several minutes to dissipate the heat in the windings.

How to synchronize a generator?

Synchronize the generator by adjusting the speed (frequency) slightly higher than the system. Observe the synchroscope or the lamps. The lamps should fluctuate from bright to dark at the rate of one cycle every 2 to 3 seconds. When the generator is in phase (the lights will be dark), close the circuit breaker.

How do you align a generator?

Dowel as follows: Check the alignment after the generator has been in operation for at least 48 hours. If alignment is not satisfactory, realign. Drill holes through the footpads and into the base in two mounting pads opposite each other. Drill the holes slightly smaller than the dowel pin. Ream the holes to the proper diameter for the pin.
