Abstract
The utility model discloses a novel high-pressure fan with isolated bearings, which comprises a motor protection shell, wherein a rotating shaft is arranged at the inner side of the motor protection shell, and a front end bearing is arranged on the outer surface of the rotating shaft and positioned at the inner side of one end of an impeller protection shell, which faces the motor protection shell; the front end bearing located on one side of the rotating shaft is installed through design, the front end bearing is far away from the fan impeller and the impeller protection shell, the front end bearing is not in contact with the impeller protection shell, the temperature of the front end bearing in the using process can be effectively reduced, meanwhile, the front end oil seal is carried out in the cavity in the front end bearing and the second bearing, dust and foreign matters can not enter the cavity, the service life of the high-pressure fan bearing is effectively prolonged, and the failure rate of the high-pressure fan is reduced.
Description
Technical Field
The utility model belongs to the technical field of high pressure positive blower, concretely relates to novel high pressure positive blower that bearing was kept apart.
Background
The high-pressure fan is a fan with the wind pressure of 30 kPa-200 KPa or the compression ratio e of 1.3-3 under the design condition. The air ring vacuum pump is generally classified as a high-pressure fan in the current industry. The high-pressure fan is also called high-pressure blower, and is different from a common centrifugal fan.
The existing high-pressure fan is characterized in that a front end bearing is fixed at the tail end of a rotating shaft and is simultaneously contacted with a fan blade protective shell, so that when the front end bearing is used, the temperature of the front end bearing is high, and dust is easily accumulated in a front end bearing cavity.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel high pressure positive blower that bearing was kept apart to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high pressure positive blower that novel bearing was kept apart, includes motor protection casing, the axis of rotation is installed to motor protection casing's inboard, the front end bearing is installed to the surface of axis of rotation and the inboard that is located impeller protection casing towards the one end of motor protection casing.
Preferably, an impeller protection shell is installed on one side of the motor protection shell, and a fan impeller is installed on the inner side of the impeller protection shell and at the end part of the rotating shaft.
Preferably, a second bearing is installed at a position corresponding to the outer surface of the rotating shaft on the inner side of the motor protection shell.
Preferably, the cavities in the front end bearing and the second bearing are sealed by the front end oil seal
Compared with the prior art, the beneficial effects of the utility model are that: the front end bearing located on one side of the rotating shaft is installed through design, the front end bearing is far away from the fan impeller and the impeller protection shell, the front end bearing is not in contact with the impeller protection shell, the temperature of the front end bearing in the using process can be effectively reduced, meanwhile, the front end oil seal is carried out in the cavity in the front end bearing and the second bearing, dust and foreign matters can not enter the cavity, the service life of the high-pressure fan bearing is effectively prolonged, and the failure rate of the high-pressure fan is reduced.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
Fig. 1 is a schematic view of the internal structure of the present invention;
in the figure: 1. a fan impeller; 2. a front end bearing; 3. a rotating shaft; 4. an impeller protection housing; 5. the motor protects the casing.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides a high pressure positive blower that novel bearing was kept apart, includes motor protection casing 5, and axis of rotation 3 is installed to motor protection casing 5's inboard, and front end bearing 2 is installed to the surface of axis of rotation 3 and the inboard that is located impeller protection casing 4 towards the one end of motor protection casing 5.
In this embodiment, it is preferable that an impeller protecting case 4 is installed at one side of the motor protecting case 5, and the fan impeller 1 is installed at an end portion of the rotating shaft 3 inside the impeller protecting case 4.
In this embodiment, preferably, a second bearing is installed at a position corresponding to the outer surface of the rotating shaft 3 inside the motor protection housing 5.
In this embodiment, preferably, the cavities in the front end bearing 2 and the second bearing are both sealed by the front end oil seal.
The utility model discloses a theory of operation and use flow: when the device uses, accessible axis of rotation 3 drives fan wheel 1 and rotates, can produce wind-force, and this process is because front end bearing 2 and impeller protective housing 4 contactless, make front end bearing 2 keep away from fan wheel 1 simultaneously, can effectively reduce the temperature of front end bearing 2 in the course of the work, and because the front end oil blanket has been carried out in the cavity in front end bearing 2 and the second bearing and has been sealed, make the unable cavity that gets into of dust foreign matter, the effectual life who improves high pressure positive blower bearing, reduce high pressure positive blower fault rate.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
