Description
Technical field
The utility model relates to a kind of air-cooled generator, particularly a kind of air-cooled generator of inner and outer air paths exchange cooling.
Background technology
The type of cooling of existing generator has water-cooled and air-cooled dual mode, if the water-cooled generator main by a water tank that places the generator outside specially, this water tank links to each other with the generator different parts by a plurality of water pipes, thus the different parts of realizing motor is lowered the temperature.Because the water-cooled generator connects the problem of water pipe, mounting arrangements also is subject to many limitations, and the degree of freedom reduces, the internal build complexity, and leakproof seal requires high, the manufacturing cost height.In addition, water-cooled generator each several part inhomogeneous cooling is even, and heat exchange is insufficient, and the motor external pipe is many, and volume ratio is bigger, and shortcomings such as inconvenience are installed.At these situations, to some use that dust storm in the open air is big, the generator of rugged environment relatively such as oil field, for reducing the generator manufacturing cost, improve the functional reliability of generator, carry out the air-cooled generator that the wind path exchange reduces temperature rise thereby had with built-in fans.But existing air-cooled generator generally all is interior circulation air path system, generator inside is provided with heat exchanger and fan reduces temperature rise, motor seal requirement height, its manufacturing cost height, internal structure complexity, overall volume are big, Heavy Weight, fitting operation inconvenience, operation noise and vibration is big, with shortcomings such as common generator interchangeability and versatility difference.Demand inventing a kind of novel air-cooled generator that overcomes above-mentioned shortcoming urgently.
Summary of the invention
The purpose of this utility model is to solve water-cooled and existing the problems referred to above of air-cooled generator in the prior art, and a kind of air-cooled generator of inner and outer air paths exchange cooling is provided.The utility model designs a kind of air-cooled generator of inner and outer air paths exchange cooling, comprise stator core, rotor core, support, the main generator rotating shaft, front end housing, rear end cap, wire box, the pilot exciter case, it is characterized in that: the both sides at the generator housing at commutator end bearing support bracket place offer two plane air inlets, on air inlet, be coated with the air inlet air strainer, the water proof rubber pad is arranged around the air inlet air strainer, in the air inlet air strainer outside air inlet cover plate is arranged, there are two air outlets both sides at the generator housing at front end of shield place, on air outlet, be coated with the air outlet air strainer, the water proof rubber pad is arranged around the air outlet air strainer, waterproof shutter cover plate is arranged in the air outlet air strainer outside.It is characterized in that: relative between wire box and the generator housing integral solder, pilot exciter case and rear end cap by seam.The utility model has the advantages that it is air-cooled enabling the generator type of cooling, simplified electric generator structure, improved the reliability of generator work.The generator inlet and outlet adopts air strainer and water proof rubber pad, need not built-in wind path interchanger, reduced its manufacturing cost, and simplify the structure, improved the stability of generator.Can be that the common generator of IP22 improves to promote and is the IP54 generator with degree of protection, improve the stability and the versatility of its parts.Unique mounting means has reduced the generator mounting process, also convenient for users to use simultaneously and maintenance.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
1 main generator rotating shaft among the figure, 2 front end housing bearing water proof and dust proofs sealing felt, 3 fans, 4 front end housings, 5 supports (bottom is equipped with the normally closed type spilled water hole), 6 stator cores, 7 rotor cores, 8 outlet water tight packing letters, 9 wire boxs, 10 rear end caps, 11 pilot exciter cases, 12 air inlet air strainers, 13 air inlet cover plates, 14 air outlet shutters, 15 air outlet air strainers.
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Among the figure, comprise stator core, rotor core, support, the main generator rotating shaft, front end housing, rear end cap, wire box, the pilot exciter case, it is characterized in that: the both sides at the generator housing at commutator end bearing support bracket place offer two plane air inlets, on air inlet, be coated with the air inlet air strainer, the water proof rubber pad is arranged around the air inlet air strainer, in the air inlet air strainer outside air inlet cover plate is arranged, there are two air outlets both sides at the generator housing at front end of shield place, on air outlet, be coated with the air outlet air strainer, the water proof rubber pad is arranged around the air outlet air strainer, waterproof shutter cover plate is arranged in the air outlet air strainer outside.It is characterized in that: relative between wire box and the generator housing integral solder, pilot exciter case and rear end cap by seam.
The generator of the utility model structure, it mainly is made up of stator core and rotor core.Stator core is by sole plate supports, and rotor core is connected with main generator rotating shaft, fan, and support and rotating shaft are by being connected and fixed before and after front end housing, the rear end cap, and the generator lead-out wire is connected and fixed by wire box.
Front end of shield is provided with bearing water proof and dust proof sealing felt, wire box is provided with lead-out wire water tight packing letter, pilot exciter case and rear end cap adopt the seam cooperation to carry out waterproof, air inlet is provided with the air intake air strainer and the air inlet cover plate carries out air intake and water proof and dust proof, and air outlet is provided with the air outlet shutter and the air outlet air strainer carries out air-out and water proof and dust proof.This outer frame spilled water hole adopts normally closed type to pin with bolt.When generator starts, the Cryogenic air of outside is sucked generator inside by fan from air inlet, during through generator inside, can absorb the heat that rotor, stator produce, and take out of from air outlet, owing to all carried out the dust and water protection processing at air inlet and air outlet place, therefore heat exchanger can be set no longer.
As mentioned above, the generator safeguard structure is air inlet air filtration and air outlet air filtration, satisfies the requirement that degree of protection is IP54, and installation and maintenance is simple and convenient, and its reliability and stability are splendid, user-friendly and maintenance.
