Description

The explosion separation structure of explosion separation motor

Technical field

This utility model relates to fire-proof motor, mainly the explosion separation motor in fire-proof motor.

Background technology

Explosion separation motor is to separate producing electric spark, electric arc and the electronic unit of dangerous temperature in motor with the mixture of surrounding damp.But, this shell is not seal, and explosive gas mixture around can enter motor internal by the gap, each several part composition surface of shell.When contacting with the Ignition sources such as the spark in shell, electric arc, dangerous high temperature it is possible to explode, at this moment the flameproof enclosure of motor not only will not damage or deform, and explosive flame or hot gases are when spreading out of by gap, composition surface, the explosive gas mixture of surrounding of can not igniting.Chiller is not mostly had on the flameproof joint of existing explosion separation motor and flame proof gap；Or cooling devcie of motor is at motor internal, it is impossible to effectively reduce the electric spark discharged and the temperature of electric arc, there is a certain degree of potential safety hazard.

Summary of the invention

In order to overcome disadvantages mentioned above, this utility model provides the explosion separation structure of a kind of explosion separation motor, including support, the first end cap, the second end cap, bearing, clutch shaft bearing lid, the second bearing cap and chiller；Described first end cap and described second end cap are separately mounted to the two ends of described support；Described bearing is fixed on described first end cap and described second end cap；Described clutch shaft bearing lid is fixed on described first cover internal, and described second bearing cap is fixed on the inside of described second end cap；Porose on described clutch shaft bearing lid and described second bearing cap it is fixed on described bearing；Described support and described first end cap form the first flame proof and connect gap；The second flame proof gap is formed with the second end cap；Described bearing forms the 3rd flame proof gap with described first end cap, forms the 4th flame proof gap with described second end cap；The 5th flame proof gap is formed between described clutch shaft bearing lid and described bearing；The 6th flame proof gap is formed between described second bearing cap and described bearing；Described chiller includes several cooler bins and storage tank；Described first flame proof gap, the second flame proof gap, the 3rd flame proof gap and the 4th flame proof gap are outside equipped with cooler bin；Each described cooler bin is arranged on the outside in described flame proof gap.

Further, described cooler bin is interconnective, and is connected formation circulation with described storage tank.

Further, described cooler bin uses polyamides fat material to make.

The explosion separation structure of the explosion separation motor that this utility model provides, adds chiller, can effectively reduce the electric arc or the temperature of electric spark discharged along flame proof gap, reduce and ignite the probability around igniting gas, improve safety coefficient；Motor internal temperature can also be reduced to a certain extent；Use polyamides fat material, have good insulating properties, be possible to prevent electric leakage；Mechanical strength is high, high temperature resistant, wear-resistant.

Accompanying drawing explanation

Fig. 1 is the side, sectional structural representation of the explosion separation structure that this utility model provides.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, this utility model is described in further details.

As it is shown in figure 1, the explosion separation structure of the explosion separation motor of this utility model offer, including support the 100, first end cap the 200, second end cap 300, bearing 400, clutch shaft bearing lid the 500, second bearing cap 600 and chiller；Described first end cap 200 and described second end cap 300 are separately mounted to the two ends of described support 100；Described bearing 400 is fixed on described first end cap 200 and described second end cap 300；It is internal that described clutch shaft bearing lid 500 is fixed on described first end cap 200, and described second bearing cap 600 is fixed on the inside of described second end cap 300；Porose fixing described bearing 400 on described clutch shaft bearing lid 500 and described second bearing cap 600；Described support 100 forms the first flame proof with described first end cap 200 and connects gap 110；The second flame proof gap 120 is formed with the second end cap 300；Described bearing 400 forms the 3rd flame proof gap 130 with described first end cap 200, forms the 4th flame proof gap 140 with described second end cap 300；Described clutch shaft bearing lid 500 forms the 5th flame proof gap 150 with described bearing 400；Described second bearing cap 600 forms the 6th flame proof gap 160 with described bearing 400；Described chiller includes several cooler bins 710 and storage tank 720；Described first flame proof gap 130, the 110, second flame proof gap the 120, the 3rd, flame proof gap and the 4th flame proof gap 140 are outside equipped with cooler bin 710；Each described cooler bin 710 is arranged on the outside in described flame proof gap.

Described cooler bin 710 is interconnective, and is connected with described storage tank 720, forms circulation.Described cooler bin 710 uses polyamides fat material to make.After motor brings into operation, electronic unit probably produces electric arc or electric spark, thoroughly do away with motor flameproof principle, the electric arc and the electric spark that produce are discharged along flame proof gap, it is provided with cooler bin outside flame proof gap and can reduce the electric arc of discharge or the temperature of electric spark, reduce the probability that outside flammable explosive gas is ignited, improve safety coefficient.

These are only this utility model preferred embodiment, therefore the scope of this utility model enforcement can not be limited according to this that the equivalence change i.e. made according to this utility model description and decoration all should belong in the range of this utility model covering.
