Description
Technical field
The utility model relates to a kind of blowers, particularly belong to a kind of various flow air blower；Belong to Fan Equipment technical field.
Background technique
Air blower is a kind of rotating vane machinery that prime mover tool can be changed into gas pressure energy.When gas passes through air inlet
After room is evenly into impeller, by the diffusion action in centrifugal force effect and impeller in the blade of rotation, make its major part
Speed can be transformed into pressure energy, and overall efficiency is higher, in sewage treatment plant (station) aeration, pumped vacuum systems, coalmine ventilation, air
The various fields such as combustion-supporting, flue gas desulfurization oxidation, exhaust gas, gas conveying, coal washing, (waterworks) air water back washing, printing
It is widely used.
In actual use, it is technical indicator that the design or type selecting of blower, which are the demands such as pressure, the flow according to gas equipment,
It would generally design or select different blowers to meet different pressure, flow demand, impeller diameter, motor speed, fortune
Turn linear velocity and determines out wind pressure, and impeller leaf road size/width of blade then determines air-out flow, the road flow little Ke Baye
Width of blade tunes up, and the road flow great Ke Baye width of blade is turned down so that blower preferably with Conditions Matching.In operational process,
Blower and Conditions Matching be realize it is energy-saving, reduce the key factor of maintenance, while ensuring operational efficiency again, this is often very
Hardly possible is realized.For example, under the premise of pressure is constant, flow is to guarantee to operate normally principal element, and flow is too big, will cause
Electric current is too high, to operate normally blower, can adjust flow by valve, but adjustable range is limited, adjusts to obtain then meeting again too much
Efficiency is influenced, surge phenomenon is easy to produce, it is unfavorable to fan operation, service life of fan may be will affect.
The blower also having in the market carries out operating condition adjusting by way of frequency control, when fan design pressure is small, stream
When measuring big, pressure can be improved by accelerating, but flow can be bigger, causes electric current exceeded；When fan design pressure is big, flow is small
When, flow can be improved by accelerating, but pressure can be higher, pressure turn of tidal stream amount efficiency substantially reduces.
Generally speaking, previous blower, which cannot achieve, carries out flow adjusting to fluid, when adjusting flow, passes through valve mostly
Shut off completion, this adjusting method brings very big restriction loss, power wastage resulting from when making flow become smaller
It is very huge.Realize that flow adjusting can be avoided restriction loss using the revolving speed for changing blower, but since gear shift device is invested
Larger, operating cost is higher, so can not be commonly used.
The Chinese patent of Patent No. CN99257105.7 discloses a kind of centrifugal device of regulating flow quantity, is suitable for
In centrifugal fan and water pump, the width of blade of centrifugal fan or water pump vane is adjusted by regulating wheel to change its flow
, since blade loads area is directly proportional to flow, under the driving for adjusting motor, when needing small flow, make partial blade
It is retracted into regulating wheel, needs to make blade by stretching out in regulating wheel when big flow.But the adjustment of blade is compared and is difficult to realize, it is special
Blade keep device fabrication more complicated, cause that the production cost increases, can not popularization and application on the market.In view of the foregoing,
It is necessary to the flow adjustings to air blower to further investigate.
