Description
Technical field
The utility model is related to air blower, specially dual-axle motor two ends direct-drive high-speed cfentrifugal blower.
Background technology
The high-speed centrifugal air blast that the industries such as traditional power plant desulfurization, sewage disposal, chemical industry, medicine, metallurgy are generally used
Machine sets speedup casing between compressor and motor, and the working speed of compressor is reached by the speedup casing speedup
Purpose.But the working method must be realized by the gear pair of a pair of precision-fits transmissions.This centrifugal blower knot
Structure is relatively complicated, and gear pair required precision is high, and difficulty of processing is big, and cost of manufacture is high；In use, easily occur
More problems, and maintenance etc. it is all more complicated.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model be to provide suitable for power plant desulfurization, sewage disposal,
The industries such as chemical industry, medicine, metallurgy, a kind of low dual-axle motor two ends direct-drive high-speed of simple in construction, easy to maintenance, production cost from
Core type air blower.
To achieve the above object, the utility model provides following technical scheme：A kind of dual-axle motor two ends direct-drive high-speed
Cfentrifugal blower, including motor and the compressor for being located at motor two ends respectively, main shaft and the motor coaxle of the compressor connect
Connect, the impeller and locking nut on the compressor are assemblied on main shaft, between the bearing and the impeller on the motor
Provided with choke sealing device and oil resistance sealing device.
Further, connected between the bearing and main shaft using static friction.
Further, the choke sealing device and oil resistance sealing device are labyrinth-type excluder.
Further, the motor is high-speed induction motor, and the high-speed induction motor is provided with PLC.
Further, it is key connection or static friction connection between the impeller and main shaft.
Advantageous effects of the present utility model are：The present invention sets high-speed induction motor main shaft and two compressor main shafts
Same main shaft is calculated as, compressor impeller is fit directly on the main shaft, and is set between motor bearings and compressor impeller
Sealing device, using high-speed induction motor band PLC, eliminates the gearbox part in existing cfentrifugal blower, letter
Structure is changed, has reduced assembly difficulty, and can effectively prevent pollution of the lubricating oil to working media, air blower is extended on a large scale
Condition range, overall structure is simple, compact, easy to maintenance, and operating efficiency is high.And a motor drives two compressor works
Make, more saved the installing space at user scene, while also meeting the bigger requirement of user.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
In figure：1st, compressor；2nd, motor；3rd, main shaft；4th, impeller；5th, locking nut；6th, bearing；7th, choke sealing device；
8th, oil resistance sealing device.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, clear, complete description is carried out to the technical solution of the utility model,
Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole embodiments.It is new based on this practicality
Embodiment in type, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, protection domain of the present utility model is belonged to.
As shown in figure 1, a kind of dual-axle motor two ends direct-drive high-speed cfentrifugal blower, including motor and it is located at motor respectively
The compressor at two ends, the main shaft of the compressor and the bearing of motor is are coaxially disposed, using quiet between the bearing and main shaft
Frictional connection.
Impeller and locking nut on the compressor are assemblied on main shaft, the bearing on the motor and the impeller
Between be provided with choke sealing device and oil resistance sealing device.The choke sealing device and oil resistance sealing device are that labyrinth type is close
Seal apparatus, can effectively ensure that sealing effectiveness.The choke sealing device can effectively prevent the working media in compressor from entering electricity
Machine.
The motor is high-speed induction motor, and the high-speed induction motor is provided with PLC.In order that air blower
Condition range increases, and meets the use of more occasions, it is ensured that compressor works in high efficiency point, high-speed induction motor band all the time
PLC, can be achieved stepless speed regulation.
It is key connection or static friction connection between the impeller and main shaft.
The foregoing description of the disclosed embodiments, is that those skilled in the art can realize or use the utility model.
To a variety of modifications of these embodiments to one skilled in the art part thing it will be apparent that as defined herein general
Principle can in other embodiments be realized in the case where not departing from scope of the present utility model.Therefore, the utility model will
It will not be limited and the embodiments shown herein, but to accord with principles disclosed herein and features of novelty is consistent
Most wide scope.
