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 the large folding current transformer of blast cabinet heat radiation without volute centrifugal fan erecting device and installation method thereof.
Background technique
Be mainly used in the forced air cooling heat radiation that requires the large converter cabinet of blast without scroll centrifugal fan.Have now and mainly adopt following two kinds of mounting types without the installation of scroll centrifugal fan: the first mounting type is first the blower fan air-ducting ring to be contained on the fan installation frame, then the impeller of centrifugal fan is contained on the fan installation plate, at last the mounting plate assembly that draught fan impeller is housed is installed on the fan installation frame.Rely on the position of adjusting draught fan impeller, regulate the coaxality of draught fan impeller and air-ducting ring.The second mounting type is first the impeller of centrifugal fan to be contained on the fan installation plate, again the mounting plate assembly that draught fan impeller is housed is installed on the fan installation frame, at last the blower fan air-ducting ring is installed on the fan installation frame, rely on the position of adjusting the 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 is to utilize the hole on bolt and the fan installation frame to locate, and bolt and interporal lacuna are large, heavier because of the assembling board component that draught fan impeller is housed again, and the sight line that filled behind the mounting plate shield, rely on the position of adjusting impeller, regulate the coaxality of impeller and air-ducting ring, impeller tends to bump to air-ducting ring when adjusting, cause the air-ducting ring distortion of blower fan, the disalignment of impeller and air-ducting ring, cause impeller not individual consistent with the gap between the air-ducting ring, after causing blower fan the blower fan dynamic balancing destroying when rotating, draught fan impeller air-ducting ring easy and blower fan is collided with, affect the life-span of blower fan, the efficient of blower fan descends greatly simultaneously.
The major defect of the second mounting type is: because the air-ducting ring of blower fan and the location of scaffold are to utilize the hole on bolt and the fan installation frame to locate, and bolt and interporal lacuna are large, rely on the position of the air-ducting ring of repeatedly adjusting blower fan, regulate the coaxality of draught fan impeller and air-ducting ring.But this regulative mode often is subject to the restriction in space, and the position of air-ducting ring is difficult for adjusting.
Existing two kinds of fan mounting devices and installation method thereof all be difficult to guarantee without the impeller of volute centrifugal fan and the coaxality between the blower fan air-ducting ring, is difficult to namely to guarantee that this gap of draught fan impeller and blower fan air-ducting ring is consistent.After the blower fan dynamic balancing destroys when draught fan impeller runs up like this, the impeller of blower fan easily with the air-ducting ring collision, reduce simultaneously the efficient of blower fan, the loss increase of blower fan, air quantity reduces.Again because heavier at the impeller of loading onto fan installation plate with the first installation method, again the shield sight line, impeller tends to bump to air-ducting ring when manually installing, and causes the air-ducting ring modification.This just more improve know clearly draught fan impeller in the running with the probability of air-ducting ring collision, the rate of fault of blower fan rises greatly, the exhaust air rate of blower fan is decrease also.
Summary of the invention
The purpose of this invention is to provide a kind of without volute centrifugal fan erecting device and installation method thereof, solved without the draught fan impeller of volute centrifugal fan in installation process and the coaxality problem of air-ducting ring, avoid making draught fan impeller collision air-ducting ring owing to the disalignment of draught fan impeller and air-ducting ring, fan efficiency is effectively brought into play.
In order to realize the foregoing invention purpose, the present invention specifically provides a kind of technic relization scheme without volute centrifugal fan erecting device, and is 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 installed on the fan installation frame, is installed on the fan installation plate without the draught fan impeller of volute centrifugal fan.Be provided with the locating stud more than three on the fan installation frame, the mounting assembly of fan installation plate and draught fan impeller is fixed on the fan installation frame by locating stud.Have between draught fan impeller and the air-ducting ring and highly be the contact ratio of b.Locating stud exposes the height h of fan installation frame attachment face more than or equal to overlap the highly b of draught fan impeller with air-ducting ring, and the center of gravity of draught fan impeller is positioned at the polygonal of the central point composition of three above locating studs.
As a kind of further improvement without volute centrifugal fan erecting device technological scheme of the present invention, be provided with three locating studs on the fan installation frame, 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 the coaxial setting of draught fan impeller leave the gap that width is a equably between air-ducting ring and the draught fan impeller.
The present invention also specifically provides a kind of technic relization scheme without volute centrifugal fan installation method in addition, and is a kind of without volute centrifugal fan installation method, may further comprise the steps:
S100: air-ducting ring is installed at fan installation frame;
S101: install locating stud more than three additional at fan installation frame, the height h that locating stud exposes the fan installation frame attachment face overlaps height b more than or equal to draught fan impeller and air-ducting ring;
S102: draught fan impeller is installed on the fan installation plate;
S103: the mounting assembly of fan installation plate and draught fan impeller is installed on the fan installation frame by locating stud, keep equably the gap that width is a between draught fan impeller and the air-ducting ring, and guarantee that the center of gravity of draught fan impeller is positioned at the polygonal of the central point composition of three above locating studs.
As a kind of further improvement without volute centrifugal fan installation method technological scheme of the present invention, install three locating studs additional at fan installation frame, the center of gravity of draught fan impeller is positioned at the triangle of the central point composition of three locating studs.
By implementing a kind of technological scheme without volute centrifugal fan erecting device and installation method thereof of the invention described above, have following technique effect:
(1) the present invention is by installing locating stud additional at fan installation frame, when being mounted to draught fan impeller on the fan installation frame, make draught fan impeller and air-ducting ring keep coaxial, make the gap between draught fan impeller and the air-ducting ring even, avoid draught fan impeller in the collision of when operation and air-ducting ring, improve the life-span of blower fan, improved simultaneously the efficient of blower fan;
(2) be installed in locating stud ride out h on the fan installation frame among the present invention greater than overlapping height b without the draught fan impeller that requires in the voluted type centrifugal fan and air-ducting ring, so the assembling board component of draught fan impeller is being installed, when adjusting the position of fan installation plate, owing to there is locating stud to head on fan installation plate, so avoided the draught fan impeller on the fan installation plate to bump to air-ducting ring, thereby guaranteed the circularity of air-ducting ring;
