Description
Technical field
The present invention relates to a kind of compressors can be applied to mechanical industry more particularly to a kind of oil-free scroll formula compressor,
Chemical industry, medical treatment, food, the energy, communications and transportation, aerospace field.
Background technique
Oil-free scroll formula compressor is that Moving plate high speed rotation compressed air under motor driven is done work, according to gas characteristic
Make the air into after compressor after exhaust outlet is discharged with the equipment of certain pressure.Due to gas inside compressor sharply
Compression and compressor part high speed rotation, lead to the temperature rise of compressor operating portion quickly, excessively high temperature has severely impacted compression
The state and performance of machine, make compressor can not long-time continuous operation, outlet gas temperature is excessively high also to imitate compressor volume
Rate is greatly reduced, and therefore, temperature how is effectively reduced as a vital ring in Compressor Technology.
Currently, existing oil-free scroll formula compressor majority, using air-cooled, one is logical in the access of compressor electric motor tail end
Air hose is connected to compressor head, is freezed using the self-contained cooling fan refrigeration of motor or incorporated fan, another kind is pressure
Plug-in or installation blower, wind directly blow to compressor head outer surface and realize refrigeration near contracting machine head.In view of oil-free scroll
The mechanostructural property of formula compressor, the above method are all haveed the shortcomings that inevitable:
1. oil-free scroll formula compressor operating portion is mostly that dynamic and static disk cooperates, belong to small―gap suture precision-fit, quiet disk is fixed not
It is dynamic, and Moving plate high speed rotation, it is above-mentioned no matter which kind of type of cooling, all can only cause dynamic and static disk temperature from the cooling quiet, Moving plate in side
It is poor to spend, and after quiet disk temperature reduces, Moving plate is still in the condition of high temperature, in this way, dynamic and static disk is because of temperature difference made of same material
Deformation difference is caused, oil-free scroll formula compressor belongs to high-precision precision-fit equipment, such influence of crust deformation compressor
Accuracy, cause gas to leak, in addition generate stuck phenomenon.
2. being equipped with anti-rotation bearing on Moving plate, the existing type of cooling can not cool down directly to bearing, lasting high temperature
Keep bearing operation unsmooth, while also reducing the service life of bearing.
Summary of the invention
The object of the present invention is to provide a kind of type of cooling that oil-free scroll formula compressor is new, which passes through in blower

On have round air inlet, be provided with waist type deflector hole on the rack, part air outlet be equipped in rack and price fixing, two pieces assembled
At rear formation air outlet.
The cooling means for being equipped with the oil-free scroll formula compressor of voltage-multiplying type axial-flow cooling fan leaf is:
After motor (or engine) starting, main shaft drives axial fan blade high speed rotation, constantly sucking from air inlet
Air (or cold air of temperature adjustable) is directly blowed to by the air inlet on deflector by the waist type deflector hole in rack
Quiet, Moving plate and bearing surface are taken away amount of heat, then are discharged by air outlet, and air-cooled circulation is formed.
Advantages of the present invention and effect:
1, the present invention directly and simultaneously cools down Moving plate, quiet disk, and Moving plate, quiet disk can be made to keep same temperature, avoided by dynamic and static disk
A series of adverse effects caused by the temperature difference.
2, the cold air of temperature adjustable can be blowed to the small bearing on Moving plate and the bearing on main shaft by the present invention, directly be made
Bearing cools down simultaneously with dynamic and static disk, preferably solves the problems, such as that bearing temperature is raw, ensure that bearing using effect and service life.
3, axial fan blade and deflector employed in the design are applied in combination, and the fan leaf of rotation is made to have axis stream wind
The advantages of flabellum and centrifugal fan impeller structure, makes air not only axially move but also does centrifugal movement, in leaf under deflector effect
Multiplication of voltage is formed between wheel and deflector.Due to being designed using axial fan blade combination deflector, coefficient of wind pres is higher than axial flow blower,
Flow-rate ratio centrifugal blower is big, keeps the wind direction of cold wind single, cooling effect significantly improves.
4, kidney-shaped deflector hole is arranged in the present invention on rack face, and the purpose is to use vent area in its effective area
The area of maximum, kidney-shaped deflector hole is bigger than the air-out area of round deflector hole.
