Abstract
Disclosed in the utility model is an explosion-proof motor for actuator. The explosion-proof motor comprising a body is characterized in that an explosion-proof housing is arranged outside the body; an opening and a connection component are arranged at one axial end f the explosion-proof housing; an end cover is connected to the opening; and heat radiation holes are formed in the end cover. A lead in the body passes through one heat radiation hole. According to the utility model, the provided explosion-proof motor has the following beneficial effects: after the end portion is fixed, the rest of housing portion exposed in the external environment can be sealed easily in an integrated way; the internal heat of the motor can be dissipated in the internal environment through the heat radiation holes, thereby removing the motor fan design; and the internal lead is directly connected in the internal environment and no junction box is exposed in the external environment, thereby avoiding the original rubber blanket and end cap bolt structure of the wire threading portion and eliminating the possibility of explosion caused by air leakage to the greatest extent.
Description
Technical field
The utility model relates to a kind of fire-proof motor, especially relates to a kind of actuator explosion-proof motor.
Technical background
In colliery, the industry such as petrochemical industry, dust, for security needs, must use fire-proof motor.Flame-proof type explosion-proof motor is the most often to use type, and concrete principle is to use flameproof enclosure to separate with explosive gas mixture around producing the electric part of spark, electric arc and dangerous temperature.
On the flameproof enclosure of above-mentioned flame-proof type explosion-proof electricity, have terminal box, back panel wiring is connected in binding post through flameproof enclosure, and the position of passing is sealed by rubber blanket and plug bolt.
Above-mentioned explosion-proof mode exists following deficiency:
1. the explosive gas mixture around can enter motor internal by the gap, each several part composition surface of shell.In the time contacting with Ignition sources such as spark in shell, electric arc, dangerous high temperature, just may blast, at this moment the flameproof enclosure of motor not only can not damage or be out of shape, and explosive flame or red-hot gas is while spreading out of by gap, composition surface, explosive gas mixture around can not ignite.
2. the heat-sinking capability of totally-enclosed environment is poor, and motor coil easily burns.
3. except motor, other parts terminal box all needs independent sealing, coupling part flame proof difficulty.
For these reasons, present stage is developed power assembly, makes entirety by parts such as motor, decelerator, controlling organizations, outside unification body seal, and motor is as an annex of assembly.
The fire-proof motor of the utility model design is exactly the equipment being applicable in above-mentioned power assembly environment.
Summary of the invention
The purpose of this utility model is to provide a kind of casing explosion-proof motor to make up the deficiency of prior art.
The technical solution adopted in the utility model is: actuator explosion-proof motor, comprise body, and it is characterized in that: this is external flameproof enclosure, and there are opening and link in the axial one end of flameproof enclosure; Opening part is connected with end cap, has louvre on end cap, and intrinsic lead-in wire passes from louvre.
Optimize, described link is flange.
The beneficial effects of the utility model are: after the utility model is fixing by end, all the other housing parts that are exposed in external environment condition are easy to realize integral sealing; Motor internal heat can be lost in internal environment by louvre, has so just cancelled the design of electric motor fan; In addition, inner lead directly connects in interior environment, does not have terminal box to be exposed in external environment, has also avoided rubber blanket and the plug bolt arrangement of original threading part, has overcome to greatest extent gas leakage and has caused the possibility of exploding.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the B-B part sectioned view of Fig. 1.
Embodiment
Embodiment:
In the drawings: the 1st, body, the 2nd, flameproof enclosure, the 3rd, flange, the 4th, end cap, the 5th, louvre, the 6th, lead-in wire, the 7th, external housing, the 8th, motor shaft.
When installation, flange 3 and external housing 7 are bolted, that motor is exposed to the part of external environment, is all shrouded by flameproof enclosure 2, there will be no wiring flame proof problem.
After end cap 4 is fixedly connected with flameproof enclosure 2, in interior environment, external housing 7(and relevant annex) play the effect of sealing.The heat that motor internal produces, from louvre 5 is discharged to interior environment, then focuses on heat dissipation problem by other means.
Lead-in wire 6 is drawn from louvre 5, the power line in directly connecting in environment.
Motor shaft 8 also completes the cooperation with other equipment in interior environment.
Claims (2)
1. actuator explosion-proof motor, comprises body, it is characterized in that: this is external flameproof enclosure, and there are opening and link in the axial one end of flameproof enclosure; Opening part is connected with end cap, has louvre on end cap, and intrinsic lead-in wire passes from louvre.
2. actuator explosion-proof motor according to claim 1, is characterized in that: described link is flange.
