Abstract
The utility model provides a kind of novel increasing peace synchronous machinery excitation machine purging aeration structure, it is characterized in that main motor space is effectively connect with exciter space with ventilation duct and flange, exciter space can be not only purged while purging main motor space, and so that exciter space and main motor space is formd circulating air duct by optimizing floor structure, preferably improve the radiating condition of exciter.
Description
Technical field
The utility model relates to a kind of novel increasing peace synchronous machinery excitation machines to purge aeration structure, solve AC exciter
Purging and cooling problem.
Background technique
Current independent external hanging type AC exciter structure has many advantages, such as that installation and maintenance are convenient, but due to exciter space
It is two spaces independently with main motor space, exciter space can not be also carried out while purging main motor space
Purging, making exciter space, there are security risks, and the type of cooling of exciter is carried out by excitation hood surface and air
Heat exchange, cooling effect are bad.
Summary of the invention
The utility model provides a kind of novel increasing peace synchronous machinery excitation machine purging aeration structure, solves independent external hanging type
The problem that AC exciter can not purge simultaneously with main motor and exciter cooling effect is bad.
The technical scheme adopted by the utility model to solve the technical problem is as follows: it includes main motor, mounting flange, sealing
Pad, loose flange, long ventilation duct, short ventilation duct, bottom plate, baffle, air outlet, air inlet, bolt, centrifugal fan and exciter,
It is characterized in that two circular holes on main motor end plate pass through long ventilation duct and short ventilation duct and exciter space fixation respectively
It orchid, loose flange, gasket and is bolted, and forms circulating air duct with baffle；Wherein short ventilation duct and exciter space
The air-flow in exciter space is introduced main motor space by air outlet connection, and long ventilation duct is connected to the air inlet in exciter space,
The air-flow in main motor space is introduced into exciter space, to complete the purging and cooling to exciter.
It, not only can be with the technical effect of the utility model is: main motor space is effectively connect with exciter space
Exciter space is purged while purging main motor space, and makes exciter space and main motor by optimizing floor structure
Space forms circulating air duct, preferably improves the radiating condition of exciter.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model top view；
Fig. 2 is the utility model structure diagram front view；
Fig. 3 is the utility model structure diagram perspective view；
Specific embodiment
The present invention will be further described with example with reference to the accompanying drawing.As shown in Figure 1, it includes 1 main motor, 2 is solid
Determine flange, 3 gaskets, 4 loose flanges, 5 long ventilation ducts, 6 short ventilation ducts, 7 bottom plates, 8 baffle A, 9 baffle B, 10 baffle C, 11
Baffle D, 12 baffle E, 13 baffle F, 14 air inlets, 15 air outlets, 16 bolts, 17 centrifugal fans, 18 exciters.
When installation, first two loose flanges 4 are screwed to respectively on the screw thread of long ventilation duct 5 and short ventilation duct 6, and be screwed into most
Right end.Then main motor 1 is installed on bottom plate, two circular holes on 1 end plate of main motor is made to be directed at two ventilation ducts.Turn two
A loose flange 4 is moved to the left, until with 1 end plate contact of main motor, with marking pen label loose flange 4 in 1 end plate of main motor
Contact profile, then loose flange 4 is moved to right end.Two mounting flanges 2 are welded to the outline position of label, then
Loose flange 4 is moved to the left, is assembled and is tightened with bolt 16 with mounting flange 2 and gasket 3, guarantee air-tightness.
When work, wind pressure is generated with the centrifugal fan 17 of 1 coaxial rotating of main motor, air-flow is by air outlet 15, through too short
Ventilation duct 6 flows in main motor 1, since 17 center of centrifugal fan is negative pressure, so 18 right hand side air of exciter flows through its air gap
Come left side, make on the right side of exciter 18 for negative pressuren zone, thus in main motor 1 air by long ventilation duct 5 by air inlet 14, reach
On the right side of exciter, to complete the purging and cooling to exciter.
