Description
Technical field
The utility model is related to a kind of flame proof integrated pump, belongs to diving pump technical field.
Background technology
Due to removing sludge use extensively, use environment is severe, and condition is poor, and space is relatively narrow and small, there is the potential of blast
It is dangerous.Such as underground coal mine blowdown, methane-generating pit small space environment are used, it is necessary to artificial pickaback hand lift, thick old bulky blowdown
Pump, it is difficult to transport to scene, or even can not be used.
Utility model content
The purpose of this utility model is to provide a kind of flame proof integrated pump, is effectively isolated motor and explosion hazard gases, it is to avoid work
During potential explosion danger.
Flame proof integrated pump described in the utility model, including motor, motor internal be provided with explosion isolation device, motor shaft run through every
Quick-fried device is set；Explosion isolation device includes housing, and housing upper is provided with end cap, and lower housing portion is provided with link, and motor shaft is through company
Frame setting is connect, housing, end cap and link enclose flame proof cavity.
Housing can bear the blast pressure of internal explosion mixture in itself, and the blast inside preventing is to shell week
Enclose explosive mixture propagation；Prevent motor and with electric parts from producing spark, the electric arc of the danger that is enough to set off an explosion
Or dangerous temperature, the band electric parts for producing these phenomenons are opened with explosive mixture cut-off, are allowed to contact with each other, greatly
The danger of potential blast is reduced greatly so that the operation of pump total system is safer more reliable.
It is further preferred that end cap includes terminal box, terminal box bottom, which is provided with the top of binding post, terminal box, is provided with upper end
Lid, terminal box and upper end cover enclose wiring cavity, and upper end cover is provided with cable feedthrough.There is provided individually wiring cavity is used for
Connecting line is accommodated, reducing connecting line is influenceed by motor course of work temperature is elevated, while also having isolated connecting line and explosive gas
Body, greatly reduces potential explosion probability.
It is further preferred that being provided with sealing shroud between upper end cover and cable feedthrough.Upper end cover and cable feedthrough can be connected
Even closer, better tightness further reduces explosion probability.
It is further preferred that housing is integrated Double-casing overcoat.Strengthen security, meanwhile, it is simple in construction, lightly, it is easy to
Carry, moreover, can adapt to the working environment of more complexity, can adapt to the working environment of more narrow spaces.
It is further preferred that being provided with cooling sandwith layer in integral Double-casing overcoat.Cooling sandwith layer can be cooled down to motor,
Explosion danger caused by temperature rise in the motor course of work is avoided, blowdown environment space is narrow and small, external using integral type bivalve
Set, the film-cooled heat of cooling sandwith layer is substantially increased, and cooling is more fully rapider, can keep the normal operating temperature of motor, greatly
Big reduction motor is because the caused explosion hazard of temperature rise.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is by setting explosion isolation device, and by electrical equipment and inflammable and explosive fried gas barrier, housing in itself can
Enough bear the blast pressure of internal explosion mixture, and the blast inside preventing is passed to ambient envelope explosive mixture
Broadcast；Prevent motor and with electric parts from producing spark, electric arc or the dangerous temperature of the danger that is enough to set off an explosion, generation
The band electric parts of these phenomenons are opened with explosive mixture cut-off, are allowed to contact with each other, are greatly reduced potential blast
Danger so that pump total system operation it is safer more reliable.
By setting integral Double-casing overcoat, solve and generally use double Shell in the prior art, it is very clumsy thick and heavy,
The problem of being difficult to carry, and do not adapt to the working environment of narrow space, light structure is readily transported, and bulk strength is big, and
And, cooling liquid and housing contact area are bigger in the cooling sandwith layer in integral Double-casing overcoat, and cooling is more abundant, and blowdown passes through
Property more preferably, processing technology is simple, saves processing charges, reduces production cost, and good appearance is generous, further reduces motor operation
The potentially danger of middle blast, enhances the safety and reliability of pump total system operation.
