Description

Streamlined axial-flow blower

[technical field]

The utility model relates to a kind of axial-flow blower, especially relates to a kind ofly having fairshaped shell construction and according to the meridian accelerating type energy-saving fan of quasi-three dimensional flow Design Theory.

[background technique]

The old type tube blower fan that use in the metal current mine is the blower fan of JF and JBT series, its shortcoming is that efficient is low, noise is high, volume is big, Heavy Weight, and this class old type tube blower fan can not be satisfied with industries such as metallurgy, coloured, gold, chemical industry, building materials to blower fan safety, energy-conservation and environmental protection requirement.

[model utility content]

Existing fan efficiency is low, noise is high, volume is big, the shortcoming of Heavy Weight in order to overcome, and the utility model provides a kind of and has the streamlined housing body structure and according to the meridian accelerating type energy-saving fan of quasi-three dimensional flow Design Theory.

The technological scheme that its technical problem that solves the utility model adopts is: streamlined axial-flow blower, comprise air intake tube, main wind tube and wind outlet barrel, air intake tube, main wind tube and wind outlet barrel are integrated to be connected, in described main wind tube, be provided with the motor fixed cover, fixed cover in motor and the main wind tube is slidingly matched, and tighten up with pressing plate, be connected with moving vane on the described motor output shaft, in described air intake tube, be provided with guide ring, this guide ring and air intake tube Joint, be provided with sub warhead in described wind outlet barrel, the shell shape of wind outlet barrel is the cylinder bodily form.

Described air intake tube inlet shell shape is tubaeform.

Described motor is a y series motor.

The beneficial effects of the utility model are: the utility model is the meridian accelerating type energy-saving fan according to the quasi-three dimensional flow Design Theory, have the efficient height, noise is low, volume is little, in light weight, efficiently distinguish advantage wide, that the property regulation scope is big; Its efficient on average improves more than 25%, is that the utility model of 7.5KW is an example with power, as working every day 18 hours, can economize on electricity every year more than 1.6 ten thousand kilowatts hours; The utility model adopts that novel y series motor is supporting, assembling form is a detachable, is convenient to maintain and replace; When design, consider the moistureproof problem of motor simultaneously, taked the totally-enclosed measure of electrical system; Wind outlet barrel is a cylinder blanket, can directly be connected with φ 400 light air tubes with the φ 500 that metal mine is used always, does not need to do in addition connecting head, and is easy to use; The utility model is fitted with anti-fracture device, to delay the blower fan pumping point, widens the steady working condition district, enlarges using scope.The utility model is applicable to non fiery mine mountains such as metallurgy, coloured, gold, chemical industry, building materials, and the ventilation dust discharge in all kinds of factory buildings and civil air defense constructions and installations and tunnel is a kind of desirable efficient, low-noise energy-saving equipment.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1-air intake tube, 2-main wind tube, 3-wind outlet barrel, 4-motor, 5-motor output shaft, 6-moving vane, 7-stator blade, 8-guide ring, 9-motor fixed cover, 10 sub warheads.

[embodiment]

Referring to Fig. 1, what Fig. 1 was represented is structural representation of the present utility model, a kind of streamlined axial-flow blower, comprise air intake tube 1, main wind tube 1 and wind outlet barrel 3, air intake tube 1,

main wind tube

2 and 3 integrated connections of wind outlet barrel, in described main wind tube 2, be provided with motor fixed cover 9, fixed cover 9 in motor 4 and the main wind tube 2 is slidingly matched, and tightens up with pressing plate, can pull down during maintenance, has the structural integrity compactness, easy to maintenance, motor 4 is selected y series motor for use, and bearing temperature should be no more than 95 ℃, and sound is even, should check immediately when undesired if any overheated or sound, as finding that bearing diminishes wound response and in time changes.Y series motor 4 adopts the oil-containing low noise bearing, and is not grease-added; This serial blower fan is furnished with y series motor, and startability is better, and fan starting is rapid, and this is a normal phenomenon, but should start 2-3 time repeatedly, in case one-shot breaks through (or dash and take off) air duct; Be connected with moving vane 6 on these motor 4 output shafts 5, moving vane 6 is used with stator blade 7, and 3 d impeller all adopts the cast inblock of high strength alloy aluminium to form, and any surface finish is firm reliable.

The center portion is provided with guide ring 8 in described air intake tube 1, this guide ring 8 and air intake tube 1 Joint; The external shape of described air intake tube 1 inlet's housing is tubaeform, can suck more air quantity.
