Abstract
The utility model relates to a motor fan air quantity regulator. The motor fan air quantity regulator mainly comprises a fan casing. The motor fan air quantity regulator is characterized in that the motor fan casing is welded with a hollow circular base board, left and right sides of the base board are provided with screw holes, bolts are welded on the screw holes, an air baffle board and a protection board of which a center is provided with a hollow circle are respectively sleeved on the bolts on the base board through elliptical holes which are vertically arranged at left and right sides of the air baffle board and the protection board, the air baffle board and the protection board are fastened through stainless steel dish-shaped nuts, the base board and two sides of a bottom portion of the protection board are connected through folding pages, and an upper portion of the air baffle board is provided with a horizontal elliptical hole. The motor fan air quantity regulator has a simple structure, is reasonable and scientific in scheme design and is convenient to use and mount, the air baffle board can be adjusted up and down along the bolts at two sides of the base board through the elliptical holes which are vertically arranged at left and right sides of the air baffle board, so inlet air quantity is adjusted, operation temperature of an outer motor bearing is improved, a lubrication effect of the motor bearing is guaranteed, and an accident of shaft suspension of a motor caused by freezing because of over-low winner outdoor temperature is avoided. According to the motor fan air quantity regulator, each part is reliably fixed, and vibration and noise do not occur.
Description
Technical field
The present invention relates to a kind of electric motor fan blast regulator.
Background technology
Because north of china in winter cold weather, the outdoor motor long-term work is below temperature-25 ℃ the time, cooling-down effect is very strong, motor fuselage particularly rear bearing heat scatters and disappears big especially, cause the motor bearings temperature to drop to below-25 ℃, the working range that surpasses motor lubricating grease has a strong impact on the normal lubricated of motor bearings, and motor seize accident often takes place.Particularly use the middle and small motor of double oil seal bearing, because lubricating grease is less in the double oil seal bearing, can't stuffing, and outdoor high-voltage motor running current is little, motor volume, fan are big, the fan for cooling effect is more obvious, easier generation motor seize accident was both brought the direct losses of repairing motor to the user, can influence enterprise's ordinary production again, causing great economic loss to enterprise, is a great difficult problem of the northern serialization of puzzlement manufacturing enterprise.
Summary of the invention
It is low excessively to the present invention seeks to solve northern cold cold weather outdoor motor bearing temperature, influences the grease lubrication effect, and the accident of motor seize very easily takes place, and electric motor fan blast regulator a kind of simple in structure, reasonable in design is provided.
Technical scheme of the present invention is: a kind of electric motor fan blast regulator, mainly contain guard, and it is characterized in that: be welded with the open circles substrate at motor fan housing; The substrate left and right sides has screw, is welded with bolt at screw; Deep bead, center are provided with the backplate of open circles, and all the elliptical aperture of vertically arranging by its left and right sides is enclosed within on the described substrate bolt, and by the locking of stainless steel dish nut; Substrate is connected by folding with the backplate two bottom sides.
Above-mentioned a kind of electric motor fan blast regulator, its described deep bead 3 tops have the horizontal ellipse hole.
The present invention compared with prior art has outstanding substantive distinguishing features, marked improvement and good effect.
(1) simple in structure, conceptual design is scientific and reasonable, and is easy to install.
(2) deep bead can be the upper and lower shift position of unit along the bolt of substrate both sides with a pitch-row by the vertical elliptical aperture in its left and right sides, to regulate the electric motor fan intake, realization fan for cooling appropriateness, improve outdoor motor bearing operating temperature, guarantee the motor bearings lubricant effect, avoid the generation of outdoor motor seize accident in winter, prevent that winter, outdoor motor fan cryogenic freezing accident took place, realize the steady safe operation of motor long period in winter, economic benefit is fairly obvious, has filled up a blank of design of electrical motor.
(3) each parts is fixing reliable, vibration and noise can not occur.
(4) deep bead top has the horizontal ellipse hole, and with regulating deep bead down on hand, the air quantity adjustment curve is level and smooth.
(5) intake of minimizing fan, the motor load electric current is corresponding to be reduced, and has the saves energy advantage.
(6) can use on the outdoor band cooling fan plant equipment in the winter time.

Embodiment:
Also by reference to the accompanying drawings the present invention is further described below by embodiment.
From Fig. 1 as seen, a kind of electric motor fan blast regulator mainly contains guard, it is characterized in that: be welded with open circles 1-1 substrate at motor fan housing; The substrate left and right sides has screw 1-2, is welded with bolt 1-3 at screw; Deep bead 3(Fig. 4), the center is provided with backplate 2(Fig. 3 of open circles 2-1), all elliptical aperture 3-1, the 2-1 that vertically arranges by its left and right sides is enclosed within on the described substrate bolt, and by with the stainless steel dish nut 1-4 locking of bolt coupling; Substrate is connected by folding 1-5 with the backplate two bottom sides.
Above-mentioned a kind of electric motor fan blast regulator is characterized in that: described deep bead 3 tops have horizontal ellipse hole 3-2.
Use of the present invention, can control the electric motor fan intake, regulate the fan for cooling effect, improve outdoor motor bearing operating temperature, guarantee the motor bearings lubricant effect, avoid the generation of outdoor motor seize accident in winter, improve fail safe and the stability of motor and plant equipment winter operation conscientiously, economic benefit, social benefit are high, are worth applying in each factory and enterprise of the north, each motor manufacturer.
