Oil supply structure of diesel generating set

The utility model is applicable to the technical field of power generation construction, and provides an oil supply structure of a diesel generating set, which comprises an oil tank, an oil storage tank, an oil supply pipeline, an oil return pipeline, a first bypass branch, a second bypass branch and a third bypass branch. According to the oil supply structure of the diesel generating set, the first bypass branch connected with the oil supply pump in parallel, the second bypass branch communicated with the atmosphere and the second end of the oil supply pipeline respectively and the third bypass branch communicated with the atmosphere and the oil return pipeline respectively are additionally arranged; and the first bypass branch, the second bypass branch and the third bypass branch can be selectively opened, so that when power is not generated, diesel oil in the oil return pipeline and the oil supply pipeline is emptied, wax precipitation is avoided, measures such as electric heat tracing are not needed, and
