Abstract

Disclosed is an electric generator, which comprises a stator (1), a generator front end cover (3), a generator rear support bracket (4) and a rotor component (5). The generator front end cover (3) and the generator support bracket (4) are both fixedly connected with the stator (1); the rotor component (5) is supported on the generator support bracket (4) through a bearing; an exhaust port (3-1) is arranged above the generator end cover (3); the exhaust port (3-1) is also respectively arranged at the lower part and both sides of the generator front end cover (3); a ring-shaped airway (2) is also nested on the generator front end cover (3); an upper exhaust port (2-1) is arranged above the ring-shaped airway (2), and a lower exhaust port is arranged below the ring-shaped airway (2); and the exhaust ports (3-1) arranged above the generator front end cover (3) are all communicated with the ring-shaped airway (2). Through additionally arranging the ring-shaped airway on the generator front end cover and additionally arranging the exhaust ports at both sides and at the lower part of the front end cover, the electric generator greatly improves the exhaust efficiency to lead high-temperature gas to be discharged in time and guarantee the electric generator to stably work.

Description

Generator

Technical field

The utility model relates to a kind of generator, is used for quiet generating set.

Background technology

The generator that prior art is used for quiet generating set only is provided with exhaust outlet above front end of shield, the exhaust cross section is less than normal, and its shortcoming is that high-temperature gas can not in time be discharged, and causes the generating built-in temperature too high, influences the stable operation of generator.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of exhaust efficiency high generator.

The technical scheme that realizes above-mentioned purpose is: a kind of generator, by stator, front end of shield, generator after-poppet and rotor assembly are formed, front end of shield is all fixedlyed connected with stator with generator support, rotor assembly is bearing on the generator support by bearing, the top of generator ' s cover is provided with exhaust outlet, the both sides of front end of shield and below also be provided with exhaust outlet, also be set with annular air channel on the front end of shield, the top of annular air channel is provided with exhaust outlet, the below is provided with down exhaust outlet, and the exhaust outlet on the front end of shield all communicates with annular air channel.

After adopting technique scheme, by on front end of shield, setting up annular air channel, and the both sides of front end housing and below the exhaust outlet that is communicated with annular air channel also set up, after the high-temperature gas of generator inside enters front end housing, can successfully enter annular air channel from a plurality of exhaust outlets on the front end housing, through annular air channel exhaust outlet discharge up and down, improve exhaust efficiency greatly again, high-temperature gas can in time be discharged, guarantee the generator steady operation.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1, a kind of generator, by stator 1, front end of shield 3, generator after-poppet 4 and rotor assembly 5 are formed, front end of shield 3 is all fixedlyed connected with stator 1 by 4 long spiro nails 6 with generator support 4, rotor assembly 5 is bearing on the generator support 4 by bearing, the top of generator ' s cover 3 is provided with exhaust outlet 3-1, the both sides of front end of shield 3 and below also be provided with exhaust outlet 3-1, also be set with annular air channel 2 on the front end of shield 3, the top of annular air channel 2 is provided with exhaust outlet 2-1, the below is provided with down exhaust outlet 2-2, and the exhaust outlet 3-1 on the front end of shield 3 all communicates with annular air channel 2.

Operation principle of the present utility model is as follows: during generator work, rotor assembly 5 high speed rotating, fan blade 7 on the rotor assembly 5 enters annular air channel 2 with generator internal high temperature gas from front end of shield 3 exhaust outlet 3-1, exhaust outlet 2-1, exhaust outlet 2-2 discharge down on annular air channel 2 again, because exhaust outlet 3-1 has increased, improve exhaust efficiency, the High Temperature Gas physical efficiency is in time discharged, guaranteed the generator steady operation.

Claims (1)

1, a kind of generator, by stator (1), front end of shield (3), generator after-poppet (4) and rotor assembly (5) are formed, front end of shield (3) is all fixedlyed connected with stator (1) with generator support (4), rotor assembly (5) is bearing on the generator support (4) by bearing, the top of generator ' s cover (3) is provided with exhaust outlet (3-1), it is characterized in that: both sides and below at front end of shield (3) also are provided with exhaust outlet (3-1), also be set with annular air channel (2) on the front end of shield (3), the top of annular air channel (2) is provided with exhaust outlet (2-1), the below is provided with down exhaust outlet (2-2), and the exhaust outlet (3-1) on the front end of shield (3) all communicates with annular air channel (2).
