Fig. 2 is the schematic flow sheet of another embodiment of blower control method of the present invention.The blower control method includes
Following steps：
In step 210, the wind pressure value and unit input power of the air blower of equipment are obtained.Such as pass through wind pressure sensor
The wind pressure value at wall-hung boiler fan outlet is detected, wind pressure sensor sends the wind pressure value of detection to controller of fan, blower fan
The current value that the master control borad of controller is fed back by itself electric circuit inspection to gas valve, and then determine unit input power.For
Burnt gas wall hanging furnace, its unit input power are unit combustion power.
In step 220, according to blast during equipment stable operation and the corresponding relation of unit input power, current blast is judged
Whether value is adapted with current unit input power.Wherein, as shown in figure 3, controller of fan can pre-save equipment stabilization
Blast and the curve map of unit input power during operation, wherein, abscissa is unit input power P, and ordinate is wind pressure value F,
L0 is blast and the corresponding relation curve of unit input power.
In step 230, if current wind pressure value and current unit input power are incompatible, dynamic adjusts rotation speed of fan.

Operating condition is adjusted and corrected according to self-operating situation dynamic, ensures equipment normal operation.
Fig. 4 is the schematic flow sheet of another embodiment of blower control method of the present invention.Enter below by taking wall-hung boiler as an example
Row explanation.
In step 410, controller of fan obtains the wind pressure value at the wall-hung boiler fan outlet of wind pressure sensor detection.Its
In, in one embodiment, wind pressure sensor can supply signal voltage U with delivery air, true according to formula U=1.23F+0.3
Make wind pressure value F.Those skilled in the art should be appreciated that the signal voltage U and wind pressure value F of different wind pressure sensor outputs can be with
There is different functional relations.
In one embodiment, the wind flow at the fan outlet of wall-hung boiler can also be obtained by air flow sensor
Value, according to wind flow and the corresponding relation of blast, the wind pressure value of the air blower of wall-hung boiler is determined according to wind flow.
In step 420, the current value that controller of fan feeds back according to gas valve determines unit input power.Wherein, combustion gas
The current value of valve feedback is bigger, then unit input power is bigger.
Wherein, step 410 and step 420 can perform simultaneously.
In step 430, blast and the corresponding relation of unit input power when obtaining wall-hung boiler stable operation.Wherein, wall hanging
Blast and the corresponding relation of unit input power can be obtained by way of described point during stove stable operation, for example, wall-hung boiler goes out
Before factory, corresponding wind pressure value under the wall-hung boiler unit input power different in stable burn is determined, then will using trace-point method
Each point connects, and obtains blast and the curve map of unit input power during equipment stable operation.Due to the sky of wind pressure sensor output
Gas, which supplies signal voltage and wind pressure value, has functional relation, and therefore, controller of fan can also preserve air as shown in Figure 5 and supply
To signal voltage U and unit input power P curve map, pair of blast and unit input power is then determined according to functional relation
It should be related to.
In step 440, judge whether current wind pressure value is adapted with current unit input power, if what is be adapted performs step
Rapid 450, if incompatible, perform step 460.
In step 450, current rotation speed of fan is kept.
In step 460, judge whether current wind pressure value is less than corresponding to current unit input power during equipment stable operation
Wind pressure value, if so, then perform step 470, otherwise, perform step 480.
As shown in fig. 6, blast and the curve of unit input power when L0 is plains region equipment stable operation, L1 are in height
Height above sea level rarefaction of air region, same wall-hung boiler corresponding blast curve under identical unit input power, L2 are sufficient in air
Area, same wall-hung boiler corresponding blast curve under identical unit input power, for example, Δ F is in a certain unit input work
Under rate, the blast deviation caused by rarefaction of air.
In step 470, rotation speed of fan is increased.In the case where blower fan revolution is certain, general mood is thinner, and wind flow will be got over
Small, wind flow is smaller, and its caused wind pressure value will be small, and fuel gas buring needs enough air quantity and corresponding blast just to can guarantee that
Equipment stable operation, therefore, it is necessary to increase rotation speed of fan.
In step 480, reduce rotation speed of fan.
In this embodiment, using blast during equipment stable operation and the corresponding relation of unit input power, when residing
When power section wind pressure sensor feedback blast is small, then need to increase rotation speed of fan；Similarly monitor current power section blast biography
When sensor feedback blast is big, then need to reduce rotation speed of fan；Therefore, no matter local rarefaction of air degree, wall-hung boiler can
From main modulation operating mode, reach and do not do any hardware modifications, ensure the normal operation of unit.

10 volumes of air.The calorific value of methane is 34.02MJ/M3, gas quantity Q1=units combustion power/34.02=1/10 air capacity Q2,
I.e. unit combustion power is equal to 3.402 times of air capacity.
In step 740, if current distinguished and admirable value and current unit input power are incompatible, dynamic adjusts blower fan and turned
Speed.For example, if current distinguished and admirable value is less than the distinguished and admirable value corresponding to current unit input power during equipment stable operation, add
Big rotation speed of fan, avoid rarefaction of air from having influence on the air quantity delivered of unit, cause unit blast protect the problem of；If current wind
Flow value is more than the distinguished and admirable value corresponding to current unit input power during equipment stable operation, then reduces rotation speed of fan.
Wherein, the corresponding relation of wind flow and unit input power is proportional relationship during equipment stable operation, but equipment
Blast and the corresponding relation of unit input power are curved line relations during stable operation.
In the above-described embodiments, using the corresponding relation of wind flow during equipment stable operation and unit input power, judge
Whether current distinguished and admirable value is adapted with current unit input power, if incompatible, dynamic adjusts rotation speed of fan, can make
Obtain equipment and adjust and correct operating condition according to self-operating situation dynamic, ensure unit normal operation.
