Description
Technical field
The invention belongs to a kind of generating set cooling technology field, and in particular to a kind of diesel generating set stator cooling dress
Put.
Background technology
It is water cooling and air cooling in the cooling technology of plant equipment, the effect of cooling is to improve the work of equipment components
Make environment, there is provided operational reliability, the reliable method of Low-voltage Electronic original paper cooled down for needs is to use air cooling, and air cooling may be used also
To apply in the light equipment for needing often to carry.
The air-cooled method of common improvement is to increase air quantity to improve cooling effect.The cooling of existing generating set exist with
Lower problem：Stator enamelled wire long term high temperature is easy to aging；Magnet because of high temperature and magnetic reduce the problem of；The cooling effect of whole unit
Difference.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of diesel generating set for above-mentioned the deficiencies in the prior art
Stator cooling device, which solves that stator enamelled wire long term high temperature is easy to aging, solves magnet because of high temperature and what magnetic reduced ask
Topic, improve the cooling effect of complete machine group.
To realize above-mentioned technical purpose, the technical scheme that the present invention takes is：
A kind of diesel generating set stator cooling device, wherein：Including stator, flywheel, studs, spring washer, nut, interior
Girth sheets, blade, girth sheets and packing ring, described stator are arranged in the centre bore of flywheel, and described interior girth sheets is arranged on flywheel
On right side, several blades are installed between described interior girth sheets and girth sheets, described studs left end is arranged on flywheel
Right side on screwed hole in, be arranged in the mounting hole of blade in the middle part of described studs, described packing ring is arranged on
On studs and packing ring is withstood on the right side of girth sheets, and described spring washer is arranged on studs and spring washer withstands on packing ring
On right side, described nut is arranged on studs and nut is withstood on the right side of spring washer.
To optimize above-mentioned technical proposal, the concrete measure taken also includes：
The above-mentioned axis of interior girth sheets and the axis of flywheel are on same straight line.
Circumferencial direction of the above-mentioned blade along interior girth sheets is evenly distributed with 12.
6 mounting holes have been distributed uniformly and circumferentially on above-mentioned girth sheets.
The axis of the axis of above-mentioned girth sheets and interior girth sheets is on same straight line.
The present invention cuts off part (sector) structure of the flywheel of engine, the structure of fan blade is redesigned, to blade
Quantity, blade area are all adjusted, and make it more rationally effective.Cooling wind is drawn into the stator in flywheel by blade
