The axial flow fan with a short air duct has the advantages of short overall length and light weight, small impeller pressure loss, low cost, small installation base for seat installation, small height for roof installation, small space usage for suspended ceiling installation, easier to be fixed for side wall installation, higher utilization safety and being more beneficial for heat radiation of the motor and convenient in transportation and installation.
Description
Technical field
The utility model relates to a kind of short air duct axial-flow blower, and it is little to be suitable for installing space, the mounting point that the load-bearing load is limited, and for example the roof load-bearing is less, the thin and narrow and small occasions such as ground supports position of sidewall thickness.
Background technique
Conventional axial-flow blower, the length that the length of air duct is added up greater than impeller and motor, the blower fan overall volume is bigger, weight is heavier, installation footprint is also bigger, the axial-flow blower of short air duct form improves to some extent in these areas, is applicable to more strict occasions such as space and weight, is enriching the axial-flow blower form.
Now the axial-flow blower on the market mostly is conventional axial-flow blower, no matter piping erection, and abutment wall is installed still the roof and is installed, and its specification is all the same.This form finds to exist some problems in long-term the use, as:
1, the blower fan volume is bigger, and it is many to produce required raw material, and to take volume big in transportation, and the mounting cost height has influenced its usage economy of blower fan;
2, blower fan weight is heavier, has not only increased transportation and installation difficulty, and to the corresponding raising of bearing power of ground or roofing, has increased the requirement to affiliated facility;
3, installation footprint is bigger, and the base floor space that requires during floor mounted is bigger, and the spacing when furred ceiling is installed between the suspension rod is bigger, has reduced the reasonable use ability in space;
4, the blower fan crushing is bigger, has influenced the overall efficiency of blower fan;
5, be unfavorable for the heat radiation of motor, increased the rate of fault of motor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of short air duct axial-flow blower of new structure, overcomes conventional axial-flow blower cost height, and volume is big, problems such as Heavy Weight.
The utility model solves the problems of the technologies described above the technological scheme of being taked: a kind of short air duct axial-flow blower, comprise impeller, motor and air duct, impeller is connected the motor front end, air duct is coated on the outside of impeller and blower fan, wherein, described air duct makes motor have at least a part of ear end face from air duct to stretch out and expose outside from the length direction shortening.
Air duct of the present utility model shortens on length as much as possible, makes the complete machine size reduce, use material few, and alleviate weight, saved cost, the air duct shorten length, the blower fan resistance reduces, and has increased air quantity, has improved efficient.Air duct all is coated on the inboard with impeller, and also the part with motor is coated on the inboard, but motor some be exposed to outside the air duct, this structural type is simple, volume is little, in light weight, and is more conducive to the heat radiation of motor.
On the basis of such scheme, on described air duct, be provided with electric source connecting box, make things convenient for power supply directly to insert motor by this electric source connecting box, be equipped with flange at the front-end face and the ear end face place of air duct again, can make things convenient for the installation of axial-flow blower.
Impeller and motor adopt the mode that directly drives to rotate, and motor can adopt the form of no cooling fan, in addition can be according to the multiple form structure of the different mining of mounting type and use occasion.
Three kinds of main mounting structures below are provided:
The first, described air duct is fixed with base on any direction up and down, carries out seat by base and pedestal and sets the position, undertaken by base and metope that side sets or lift the location by base and hanging piece.
On the basis of such scheme, described base is divided in two parts, and is installed in the front-end face flange and the ear end face flange inboard of air duct respectively, because the shorten length of air duct, so the also corresponding shortening of the distance between base two-part.
The second, described axial-flow blower is embedded installing and locating in abutment wall, and protective net all is installed on the flange of air duct front and rear end, enters blower fan to prevent foreign matter, and influence is used.The 3rd, described axial-flow blower is installed on the roof flashing, on the air duct front-end face flange flashing cap is installed, and this flashing cap and roofing flashing installing and locating are equipped with rainhat on the air duct ear end face flange, and the part that motor is exposed to air duct is positioned at this tarpaulin inboard.
The beneficial effects of the utility model are:
Complete machine length is short, in light weight, the pressure loss of blower fan own is little, it is little that cost is low, seat is adorned required installations basis, and the roof setting height(from bottom) is low, furred ceiling is installed little, the abutment wall installation of taking up room and is easier to fix, and safety in utilization is higher, be more conducive to motor radiating, and be easy to transportation and installation.
