Abstract
A kind of explosion separation structure, it is characterized in that：One cylindrical shape flameproof joint of the endoporus of bearing holder (housing, cover) and the cylindrical composition of rotating shaft, the annular groove of bearing holder (housing, cover) and the inside and outside circle of curved path ring constitute the first cylindrical shape flameproof joint and the second cylindrical shape flameproof joint, these three flameproof joints are combined in concentric circles, and the labyrinth shape explosion separation structure of three flameproof joints can only be passed sequentially through by forming explosive flame.The structure can effectively prevent the explosive mixed gas containing acetylene when motor interior occurs blast and burnt, explosive flame causes the explosive gas atmosphere of outside to explode by electric rotating machine rotating shaft composition surface, has effectively ensured production equipment and the safety of personnel.
Description
(1) technical field
The technical field that this patent is related to is：The flameproof joint of electric rotating machine rotating shaft is the phase asynchronous electricity of high voltage flameproof
The important feature of motivation, is also to be easiest to occur flameproof joint at the one of quick-fried accident thoroughly in motor.The flame proof as can be seen here
Vital effect is played in face of the explosion insulation performance of whole motor.
(2) background technology
The capital equipment that high-pressure explosion-proof type three-phase asynchronous is changed as petrochemical enterprise electric energy, using very wide
It is general.With oil, there is acetylene gas and the explosivity of air formation in its production equipment and factory building in the development of the enterprise such as chemical industry
Gaseous environment (hereinafter referred to as acetylene environment).Now the high-pressure explosion-proof type three-phase asynchronous of driven equipment must also reach second
The requirement of alkynes environment explosion-proof motor.The rotation of the Flame-Proof Three-Phase Induction Motors of Current Domestic seat No. more than 355
It is outside quick-fried that the explosion separation structure on machine shaft composition surface can not effectively prevent acetylene explosive flame from being ignited by rotating shaft composition surface
Fried property gaseous environment, that is, often say it is saturating quick-fried, affect acetylene environment Flame-Proof Three-Phase Induction Motors always for many years
To in using high-tension motor as representative, large-size machine development.Acetylene environment high-pressure explosion-proof type three-phase asynchronous rotating shaft
What therefore composition surface explosion separation structure (the hereinafter referred to as explosion separation structure) was exactly invented.
(3) content of the invention
The problem of to solve easily thoroughly quick-fried when high-tension motor rotating shaft explosion separation structure is used in acetylene environment, electric rotating machine
Rotating shaft flameproof joint must use new explosion separation structure, present invention provides a kind of practicable explosion separation structure, effectively
Solve the problems, such as the flame proof of acetylene environment high-tension motor rotating shaft faying face.
The explosion separation structure is made up of bearing holder (housing, cover) 1, curved path ring 2, rotating shaft 3；Bearing holder (housing, cover) 1 is by bearing holder (housing, cover) 7, lining ring 8, curved path ring 9
Assemble, wherein lining ring 8, curved path ring 9 is made of no-spark metal material, matching somebody with somebody between curved path ring 9, lining ring 8 and bearing holder (housing, cover) 7
Conjunction uses interference fit to prevent acetylene gas explosive flame from igniting outside acetylene explosive gas by fit engagement face
Environment.Bearing holder (housing, cover) 1 after the completion of assembling constitutes cylindrical shape flameproof joint 4 with rotating shaft 3, and bearing holder (housing, cover) 1 is constituted with curved path ring 2
The first cylindrical shape flameproof joint 5 and the second cylindrical shape flameproof joint 6 are constituted, these three flameproof joints are combined one
Act the flameproof joint for together constituting a labyrinth shape.When motor internal occurs blast and burnt, explosive flame must be according to
It is secondary to be only possible to ignite external environment condition by flameproof joint 4,5,6, because blast pressure is passing through the labyrinth shape flameproof joint
When progressively decay, final explosive flame can not be delivered to outside motor, thus reach prevention motor interior occur blast and
Cause the purpose of the explosive gas atmosphere blast of outside during burning, effectively ensure production equipment and the safety of personnel.
(4) illustrate
The invention will be further described with implementation below in conjunction with the accompanying drawings.
Fig. 1 is electric rotating machine rotating shaft composition surface structure chart：Bearing holder (housing, cover) 1, curved path ring 2, rotating shaft 3
Fig. 2 is the structural representation of bearing holder (housing, cover) 1；Bearing holder (housing, cover) 7, lining ring 8, curved path ring 9
(5) embodiment
Embodiments of the present invention are described below in conjunction with the accompanying drawings：
1. lining ring 8 is set in bearing holder (housing, cover) 7, it is processed after installation and reaches required size.
2. curved path ring 9, which is processed, reaches required size.
3. curved path ring 9 and bearing holder (housing, cover) 7 after machining, lining ring 8 carry out being assembled to form bearing holder (housing, cover) 1, now curved path ring
9th, all gap is not present for interference fit composition surface in the composition surface between lining ring 8 and bearing holder (housing, cover) 7.
4. the bearing holder (housing, cover) 1 after the completion of assembling carries out static pressure test.
5. curved path ring 2 all machines after rear and bearing holder (housing, cover) 1 is assembled with rotating shaft 3 and forms flameproof joint, constitute
Complete rotating shaft flameproof joint structure.
Claims (1)
1. a kind of explosion separation structure, it is characterized in that：The endoporus of bearing holder (housing, cover) (1) and one cylindrical shape flame proof of cylindrical composition of rotating shaft (3)
The inside and outside circle of composition surface (4), the annular groove of bearing holder (housing, cover) (1) and curved path ring (2) constitutes the first cylindrical shape flameproof joint (5) and the
Two cylindrical shape flameproof joints (6), these three flameproof joints are combined in concentric circles, and forming explosive flame can only be according to
The secondary labyrinth shape explosion separation structure by three flameproof joints.
