According to the anti-thermal-expansion structure for the foundation of the air blower, the anti-thermal-expansion structure for the foundation is additionally arranged on a turbo-blower on the basis that the temperature is changed, the turbo-blower is not directly connected with a blower foundation base board, instead, the turbo-blower is connected with the blower foundation base board through the fastening piece, a certain motion space is supplied to the blower base board, the problems that a machine set deflects in the axial direction or in the radial direction and vibrates, the temperature of a bearing is increased, and the performance of the bearing is not up to the standard are solved.
Description
Technical field
The invention belongs to the turbo blower field, be specifically related to the anti-basal heat expansion mechanism of a kind of blower.
Background technique
Turbo blower is a kind of rotating vanes machinery.The raising of gas pressure is to utilize the interaction of blade and gas to reach, and its voltage rise is about 0.015-0.35MPa.Because of its voltage rise higher, its impeller acting energy head height, a part of mechanical energy that is difficult to avoid is converted to heat energy, causes the unit temperature rise to raise.Because thermal expansion causes unit to produce radial and axial displacement, make inner cooperation of unit ensue variation, be unfavorable for the unit smooth running.Common is unit vibration, damage of bearings, and aeroperformance can't satisfy owner's requirement etc.
Traditional thermal expansion bloated organizational structure and staff locating piece directly links to each other with fan casing base plate and fan casing, positioning plate and fan supporter are welded to connect, and link to each other with the blower fan base plate by fastening piece again, and wherein positioning plate is spacing dead, can't move, can only move its displacement effect that reaches by housing.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides the anti-basal heat expansion mechanism of a kind of blower, avoid turbo blower to be subjected to displacement.
Technological scheme: a kind of blower is prevented the basal heat expansion mechanism, described mechanism is installed on the chassis backplane, fixedly connected with ground by stone bolt, mechanism comprises pressing plate, clamping sleeve, expansion slide plate and fastening piece, described expansion slide plate is connected with the blower foundation cemented, described pressing plate and clamping sleeve from top to bottom successively socket be connected on the stone bolt, pressing plate compresses clamping sleeve, has the gap between clamping sleeve and the chassis backplane.
Because turbo blower on the basis that temperature changes, has been set up anti-basal heat expansion mechanism, directly do not cooperate with the blower foundation base plate by fastening piece, keep blower fan base plate certain movement space.
As a further improvement on the present invention, described fastening piece comprises stone bolt, thin nut, nut, spring washer and plain washer.Stone bolt from top to bottom successively socket be connected with thin nut, nut, spring washer, plain washer, pressing plate and clamping sleeve.Adopt this means of fixation, problem such as can prevent that unit from producing axially and radial displacement, vibration, bearing temperature rise improve, performance is not up to standard.
As a further improvement on the present invention, described expansion slide plate is connected by grouted solid with blower foundation cement, so that blower fan base plate active force on the expansion slide plate, behind the maintenance blower fan expanded by heating, can axially and move radially.
As a further improvement on the present invention, described stone bolt is fixedlyed connected with the round steel welding.
As a further improvement on the present invention, the gap is 0.1-3mm between described clamping sleeve and the chassis backplane, and as optimization, the gap is 1mm between described clamping sleeve and the chassis backplane.So that pressing plate directly is not applied to blower fan base plate place.
As a further improvement on the present invention, described clamping sleeve is the cylinder type lasso.The inner ring diameter of clamping sleeve is 36cm, and race diameter is 50cm, highly is 31cm.Simple, safe, the easily installation of this lasso manufacturing greatly reduces the unit maintenance rate, has improved the unit operation stationary time.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the local enlarged diagram among Fig. 1;
Fig. 3 is the structural representation of clamping sleeve among Fig. 1.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Embodiment
As shown in Figure 1, 2, 3, a kind of blower is prevented the basal heat expansion mechanism, mechanism is installed on the chassis backplane 10, fixedly connected with ground by stone bolt 4, mechanism comprises pressing plate 1, clamping sleeve 2, expansion slide plate 3 and fastening piece, and expansion slide plate 3 is connected with the blower foundation cemented, pressing plate 1 and clamping sleeve 2 from top to bottom successively socket be connected on the stone bolt 4, pressing plate 1 compresses clamping sleeve 2, has the gap between clamping sleeve 2 and the chassis backplane 10.Fastening piece comprises stone bolt 4, thin nut 5, nut 6, spring washer 7 and plain washer 8.Stone bolt 4 from top to bottom successively socket be connected with thin nut 5, nut 6, spring washer 7, plain washer 8, pressing plate 1 and clamping sleeve 2.Expansion slide plate 3 is connected by grouted solid with blower foundation cement, so that blower fan base plate active force on the expansion slide plate, behind the maintenance blower fan expanded by heating, can axially and move radially.Stone bolt 4 is fixedlyed connected with round steel 9 welding.The gap is 0.1-3mm between clamping sleeve and the chassis backplane, so that pressing plate directly is not applied to blower fan base plate place.The gap is 1mm between clamping sleeve 2 and the chassis backplane.Clamping sleeve 2 is the cylinder type lasso.The inner ring diameter of clamping sleeve 2 is 36cm, and race diameter is 50cm, highly is 31cm.
For those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
This thermal expansion mechanism principle is, directly do not cooperate with the blower foundation base plate by fastening piece, keep blower fan base plate certain movement space, because the blower temperature often reaches 200 ~ 300 ℃, the overheated housing that causes is subjected to displacement, extremely can influence basic stress as spacing mistake and concentrate, thereby cause the basis cracking to damage.
This thermal expansion mechanism and original expansion locating piece, difference is that former mechanism is that the expansion locating piece directly links to each other with fan casing base plate and fan casing, positioning plate and fan supporter are welded to connect, link to each other with the blower fan base plate by fastening piece again, wherein positioning plate is spacing dead, can't move, can only move its displacement effect that reaches by housing.Its effect major part is that also the blower fan medium temperature is on the low side, but because draught fan impeller work done, a kinetic energy part is converted into heat energy, and blower fan outlet end temperature is too high, causes the displacement of the overheated generation axial-radial of outlet side inner sealing to prevent that limit is dead thereby cause Blower Housing one side to expand.This structure generally only is installed in blower fan support end (free end).
This patent of invention of applying for is that the medium temperature of blower fan own reaches under the situation more than 200 ℃, and housing freedom, fixed end all need be installed this mechanism.
The present invention at turbo blower on the basis that temperature changes, set up anti-basal heat expansion mechanism, directly do not cooperate with the blower foundation base plate by fastening piece, keep blower fan base plate certain movement space, problem such as prevent that unit from producing axially and radial displacement, vibration, bearing temperature rise improve, performance is not up to standard.
