Pipeline one end in water-cooled generator is parallel with two laterals,
Wherein one lateral is provided with the 5th valve and the 6th valve, and the lateral end is provided with stator cooling water
Source, another lateral is provided with the 7th valve and the 8th valve, the lateral between the 7th valve and the 8th valve
The air compression pipe with the 9th valve is provided with, the air compression pipe is connected with air compressor；
The other end of the pipeline in water-cooled generator is equally parallel with two laterals,
Wherein one lateral is provided with the first valve and the second valve, and the lateral end is provided with backwashing water
Source, the
Lateral between one valve and the second valve is provided with the pipeline with the tenth valve, on another lateral
It is provided with the 3rd valve and the 8th valve.
It is using the beneficial effect produced by above-mentioned technical proposal：
Original backwash application technology on the basis of, be improved, using air-water mixture scouring force it is strong the characteristics of, realize
Whole air-water mixture backwash, improves rinsing quality, it is ensured that while the backwash effect of generator cooling-water loop, and it is fixed to reduce
Sub- cooling water amount and backwashing time.
