Description
Technical field
The present invention relates to a kind of fan mounting device and installation method thereof, be specifically related to a kind of be applied to require blast large folding current transformer cabinet heat radiation without volute centrifugal fan erecting device and installation method thereof.
Background technique
The forced air cooling heat radiation of the converter cabinet requiring blast large is mainly used in without scroll centrifugal fan.The existing installation without scroll centrifugal fan mainly adopts following two kinds of mounting types: the first mounting type first blower fan air-ducting ring is contained on fan installation frame, then the impeller of centrifugal fan is contained on fan installation plate, finally the mounting plate assembly that draught fan impeller is housed is installed on fan installation frame.Rely on the position of adjustment draught fan impeller, regulate the coaxality of draught fan impeller and air-ducting ring.The second mounting type first the impeller of centrifugal fan is contained on fan installation plate, again the mounting plate assembly that draught fan impeller is housed is installed on fan installation frame, finally blower fan air-ducting ring is arranged on fan installation frame, rely on the position of adjustment blower fan air-ducting ring, regulate the coaxality of draught fan impeller and air-ducting ring.
The major defect of the first mounting type is: because the location of draught fan impeller and scaffold utilizes the hole on bolt and fan installation frame to locate, and bolt and interporal lacuna large, assembling board component again because being equipped with draught fan impeller is heavier, and shield sight line after having filled mounting plate, rely on the position of adjustment impeller, regulate the coaxality of impeller and air-ducting ring, when adjusting, impeller often bumps to air-ducting ring, the air-ducting ring of blower fan is caused to be out of shape, the disalignment of impeller and air-ducting ring, cause the gap between impeller with air-ducting ring not individual consistent, after causing blower fan blower fan dynamic balancing destroying when rotating, draught fan impeller air-ducting ring that is easy and blower fan is collided with, affect the life-span of blower fan, the efficiency of blower fan declines greatly simultaneously.
The major defect of the second mounting type is: because the air-ducting ring of blower fan and the location of scaffold utilize the hole on bolt and fan installation frame to locate, and bolt and interporal lacuna large, rely on the position repeatedly adjusting the air-ducting ring of blower fan, regulate the coaxality of draught fan impeller and air-ducting ring.But this regulative mode is often subject to the restriction in space, the position of air-ducting ring not easily adjusts.
Existing two kinds of fan mounting devices and installation method thereof are all difficult to ensure the coaxality without between the impeller of volute centrifugal fan and blower fan air-ducting ring, and it is consistent to be namely difficult to this gap of guarantee draught fan impeller and blower fan air-ducting ring.After when draught fan impeller runs up, blower fan dynamic balancing destroys like this, the impeller of blower fan easily collide with air-ducting ring, reduces the efficiency of blower fan simultaneously, the loss increase of blower fan, air quantity reduction.Again due to heavier at the impeller loading onto fan installation plate with the first installation method, when shield sight line, artificial installation, impeller often bumps to air-ducting ring again, causes air-ducting ring modification.This just improves the probability that draught fan impeller of knowing clearly collides with air-ducting ring in the running more, and the rate of fault of blower fan rises greatly, and the exhaust air rate of blower fan also significantly reduces.
Summary of the invention
The object of this invention is to provide a kind of without volute centrifugal fan erecting device and installation method thereof, solve without the draught fan impeller of volute centrifugal fan in installation process and the coaxality problem of air-ducting ring, avoid the disalignment due to draught fan impeller and air-ducting ring and make draught fan impeller collide air-ducting ring, fan efficiency is effectively played.
In order to realize foregoing invention object, the present invention specifically provides a kind of technic relization scheme without volute centrifugal fan erecting device, a kind of without volute centrifugal fan erecting device, comprising: fan installation plate, locating stud, fan installation frame and air-ducting ring.Air-ducting ring is arranged on fan installation frame, and the draught fan impeller without volute centrifugal fan is arranged on fan installation plate.Fan installation frame is provided with the locating stud of more than three, the mounting assembly of fan installation plate and draught fan impeller is fixed on fan installation frame by locating stud.Have between draught fan impeller and air-ducting ring is highly the contact ratio of b.The height h that locating stud exposes fan installation frame attachment face is more than or equal to the height b that overlaps of draught fan impeller and air-ducting ring, and the center of gravity of draught fan impeller is positioned at the polygonal of the central point composition of more than three locating studs.
As a kind of further improvement without volute centrifugal fan erecting device technological scheme of the present invention, fan installation frame is provided with three locating studs, the center of gravity of draught fan impeller is positioned at the triangle of the central point composition of three locating studs.
As a kind of further improvement without volute centrifugal fan erecting device technological scheme of the present invention, air-ducting ring and draught fan impeller are coaxially arranged, and leave the gap that width is a between air-ducting ring and draught fan impeller equably.
The present invention also specifically provides a kind of technic relization scheme without volute centrifugal fan installation method in addition, a kind of without volute centrifugal fan installation method, comprises the following steps:
S100: install air-ducting ring on fan installation frame;
S101: the locating stud installing more than three on fan installation frame additional, the height h that locating stud exposes fan installation frame attachment face are more than or equal to the height b that overlaps of draught fan impeller and air-ducting ring;
