Installation base 45 after installation base 44, silencer before sound device) be mounted on center it is contour embrace band component on after, all centres of gyration
It is on same centre of gyration line 43；Air inlet silencer installs filtering screen 46 in inlet end), prevent fifth wheel from sucking wind
The normal work of machine internal influence blower.
As shown in fig. 7, the mechanical mounting interface of fan part and mesh enclosure component is similar to fan part and air inlet is eliminated the noise
The mechanical mounting interface of device.
First clip 3 is identical with the structure composition of the second clip 5, and identical with 25 structure of clip on component with embracing.
Main part fan part 10, backup fan part 1 and the installation diagram of 4 pipeline of triple valve are as shown in Figure 10.Blower
Rubber shock-absorbing pad 48 is bonded inside air outlet shell 47, Rubber shock-absorbing pad 48 is for buffer metal ball 9 and fan outlet shell
47 shock；First clip 3 (or the second clip 5, figure in by taking the first clip 3 as an example) is for connect the blower for fastening fan part
Air outlet shell 47 and triple valve 4；Sealing ring 49 is mounted in the installation seam allowance of 4 end face of triple valve, for reducing part connection
The air quantity at place leaks；Metal ball 9 is mounted in triple valve 4, and 9 sphere outer diameter of metal ball is slightly less than 4 internal diameter of triple valve, metal ball 9
Sphere can freely roll in triple valve 4.
As shown in figure 11, more dowels 51 are designed in 4 gas outlet of triple valve, can prevent metal ball 9 from blocking air outlet.
As shown in figure 12, the present invention is fixed and is transported using tool base plate 72, pass through work during assembling test
Dress fastening screw 71 is fixed in tool base plate 72.
General in use, as shown in Figure 1, install air inlet silencer 13 on main part fan part 10, and back up blower
Mesh enclosure component 7 is installed on component 1, and since backup fan part 1 is identical with the performance and structure of main part fan part 10,
As shown in figure 13, mesh enclosure component 7 is installed on main part fan part 10, and backs up installation air inlet silencer 13 on fan part 1,
Present invention is equally capable to operate normally.
Difference based on mounting means, the present invention can be run with multiple-working mode:
Operating mode one: main part fan part work, backup fan part is standby, low noise working condition
When main part fan part is powered on, air-flow is flowed into inside fan part by air inlet silencer, then from main part
The outflow of fan part air outlet, and metal ball is blowed into the air outlet of backup blower and is blocked, main part fan outlet and three
Port valve air outlet forms current path, and last air-flow is flowed out from triple valve air outlet, and fan assembly is in low noise working condition.
Operating mode two: main part fan part failure, the work of backup fan part, normal noise working condition
Main part fan part service life exhausts or when chance failure, and main part fan parking, up-stream system circuit is switched to backup
Fan part work.When backup fan part is powered on, air-flow is flowed into inside fan part by mesh enclosure component, then from backup
The outflow of fan part air outlet, and metal ball is blowed into the air outlet of main part blower and is blocked, backup fan outlet and three
Port valve air outlet forms current path, and last air-flow is flowed out from triple valve air outlet, and fan assembly is in normal noise work shape
State.Main part fan part be in etc. replacement state to be repaired.
Operating mode three: main part fan part failure, the work of backup fan part, low noise working condition
Main part fan part service life exhausts or when chance failure, main part fan parking, manually unscrews and embraces at two with component
Wing nut is opened and embraces band component, air inlet silencer is removed from main part fan part position and is moved to backup blower portion
Part air inlet position, while mesh enclosure component being removed to the main part air inlet position for moving failure, tighten all armfuls of band groups
Part, then up-stream system circuit is switched to the work of backup fan part.When backup fan part is powered on, air-flow passes through air inlet
Mouth silencer flows into inside fan part, then flows out from backup fan part air outlet, and metal ball is blowed to main part blower
Air outlet simultaneously blocks, and backup fan outlet and triple valve air outlet form current path, and last air-flow is from triple valve outlet air
Mouth outflow.
Repair and replacement mode: when main part fan part or backup fan part failure, fan part dismantling replacement
When main part fan part or backup fan part failure, manually unscrew failure fan part position embrace band component and
The wing nut of clip is opened and embraces band component and clip, then takes out failure fan part, more inletting fresh air machine component, then again
It tightens and embraces band component and clip.
