Description
Technical field
Being moved the utility model is related to mining site aeration technology field more particularly to electric motor built-in adjusts fan improvement mining right
A kind of ventilating system of cyclone cluster.
Background technology
Two main fans are installed in the main fan room of general coal mine, and the method for operation is an operation, and one spare, and real
The capable monthly switchover operation of falling machine, angle of fan leaves adjusting is cumbersome, and after needing fan parking, every blade is individually adjusted, operation
Efficiency is low, and generally between 30~60%, and the wind turbine must overhaul every year and replacement motor bearings etc..
Applicants have discovered that at least there are following technical problems for the prior art：
1. axle stretch end bearing service life is short.
Since the design concept of counter-rotating fan is exactly that impeller is directly hung on the axis of motor, so the centrifugal force of impeller, leaf
Thrust that piece is generated by the reaction force of wind, the remaining out-of-balance force of regulating system, electromagnet pull, airflow pressure variation etc.
Form Equivalent Dynamic Load Deng generated radial load, axial force in the operating of, these wind turbines, be all cause bearing damage it is fatal because
Element.So the bearing close to motor-shaft extending end is caused often to seize, burn, entire stator winding is burned out when serious, serious shadow
It rings the ventilation safety of entire mine or even threatens to mine safety and the person and life security of absence from work without reason.
2. secondary motor is easily burnt.
Since the design concept of counter-rotating fan is exactly directly to be hung on the axis of two motors using stage impeller, work
When both stage impellers reversely revolve, both stage impellers guide vane each other so the matching requirement to both stage impellers is higher, and actually uses
Middle discovery, often when increasing ventilation distance, secondary motor load is increased faster than primary motor, reaches certain logical when the later stage
Wind apart from when, although the general power of two-stage wind turbine has not yet been reached 2 times of single-stage, the load of secondary motor far beyond
Rated power thus often results in the overload operation of secondary motor, so as to cause burning for motor.
3. noise is big.
Coal mine has often buried the sound and other alarm sounds of miscellaneous equipment mal-operation because fan noise is big
Etc., so as to cause the generation of excessively many malignant events, so it is also imperative to reduce fan noise.
4. inefficiency.
The current efficiency to cyclone stage only 40% or so, thus to the wind turbine carry out reducing energy consumption when it is very necessary, and
The energy saving space is very huge.
5. blade angle adjustment is difficult.
Since the regulative mode of counter-rotating fan blade angle is adjusted for monolithic after shutting down, first, this adjustment of blade angle side
Formula is difficult to keep the consistency of blade angle, second is that coal mine environment is severe, often in long-term dust stratification, abrasion and corrosion situation
Under, the angle mark of blade can become blurred, and regulating mechanism rust is dead, so that blade angle can not often adjust at all, institute
Often when blade angle needs adjustment, various unpredictalbe situations to be caused to take place frequently due to the method for adjustment has failed,
Ventilation safety and the safety in production of mine have been seriously affected, to daily management and has ensured that mining ventilation and safety causes greatly to hinder
Hinder.
