Description
Technical field
The present invention relates to the auxiliary operation system field of fresh air system more particularly to a kind of screen replacings of fresh air system
Reminding method.
Background technique
Fresh air system in the process of running, is required to filter out the granule foreign in air by strainer, since gas is to hold
It is continuous by strainer, therefore a large amount of granule foreign can be assembled on the position of strainer.These granule foreigns gather it is more after, meeting
Opening of sieve is blocked, the normal work of strainer is influenced, will lead to the ventilatory capacity decline of fresh air system under serious conditions, single unit system
Intercourse meeting degradation；At this time, it is necessary to which operator carries out replacement sieving operation.
Therefore, for fresh air system, it is main in fresh air system operational process for how reminding operator to replace strainer
One of ask a question, there are a variety of reminding methods on the market at present, one is correlation detector detections, when detector detects fresh air
When containing impurity in the wind of system discharge, then prompting changing filtering net；This method is led firstly the need of other detection devices are installed additional
The erection increased costs of fresh air system are caused, and the impurity that detector detects is not necessarily as caused by filter net jam, is also had
May be in fresh air system other assemblies failure cause, precision is not high；Another kind is judged by air quantity or power detection
What whether strainer needed replacing, still, in the process of running due to blower, electric current, the electricity of filter net jam meeting combined influence blower
The factors such as pressure, power and ventilation quantity, are the comprehensive functions by many factors, whether judge strainer only by single data
It needs to detect, it is evident that precision is inadequate；Moreover, the case where being detected by these equipment, is the working condition of blower reaction,
For the dust load situation of strainer itself, these data are all the data of side reaction, and being by these equipment cannot be accurate
It obtains.
Summary of the invention
In view of the above problems, convenient precisely judge that strainer is born it is an object of that present invention to provide a kind of easy to operate
Carry situation, the method for the strainer prompt replacement of low-cost fresh air system.
In order to achieve the above object, The technical solution adopted by the invention is as follows: a kind of strainer of fresh air system prompts replacement
Method, the method the following steps are included:
1) strainer for selecting fixed specification, when strainer zero load, the weight for detecting strainer is Q0, work is carried out using the strainer
Make, measurement strainer work stylish wind system wind-force electrical machinery speed electric V0, electric current I0And power P0；
2) strainer in step 1) is selected, when the strainer full load, the weight for detecting strainer is Q1, carried out using the strainer
Work, measurement strainer work stylish wind system wind-force electrical machinery speed electric V1, electric current I1And power P1；
3) according to step 1), 2) in as a result, obtaining the strainer in unloaded and full load, the variation range of the weight of strainer
Q0~Q1, the variation range V of speed electric1~V0, the variation range I of electric current1~I0With the variation range P of power1~P0；
4) to weight range Q0~Q1Interior multiple strainers are tested, and measure tune corresponding to different strainer weight respectively
Fast voltage, electric current and power, are computed, and respectively obtain the functional relation of speed electric and weight, the function pass of electric current and weight
System, the functional relation of power and weight；
5) the relevant functional relation of three weight obtained in step 4) is imported into central processing unit, which is filled
Enter fresh air system, starts to work normally, real-time detection speed electric Va, electric current Ia and power P a in the course of work；
6) central processing unit is according to speed electric Va, electric current Ia and the power P a of the measurement in 5), according to respective function
Relationship obtains the corresponding weight Qva of speed electric, the corresponding weight Qia of electric current and the corresponding weight Qpa of power respectively；
7) by Qva, Qia and Qpa three respectively with Q1It compares, when any one value is greater than or equal to Q in three1When,
Central processing unit issues warning signal, and operator is reminded to replace strainer；
8) by Qva, Qia and Qpa three respectively with Q1It compares, when three is respectively less than Q1When, strainer is calculated by formula
Load capacity F,, obtained load capacity is passed through aobvious
Showing device is shown, the pot life of operator's strainer is reminded.
When fresh air system of the present invention uses direct current generator as wind drive, data obtained in step 6) are
Va, Ia and Pa, the strainer weight further obtained are Qva, Qia and Qpa.: blower is in negative pressure or under tending to vacuum environment, rotation
Resistance reduces, and revolving speed can become faster, but when rotation speed of fan is faster than direct current generator setting speed, voltage can be reduced voluntarily, to reduce
Rotation speed of fan.
When fresh air system of the present invention uses alternating current generator as wind drive, speed electric will not change,
Data obtained in step 6) are Va and Pa, and the strainer weight further obtained is Qva and Qpa；Alternating current generator does not have revolving speed anti-
Feedback signal line can not obtain tach signal, the variation that can also reduce with regard to speed electric is not present, and after filter net jam, blower is negative
Pressure tends under vacuum environment, and rotary resistance reduces, and revolving speed can become faster, but without detection signal output.
When direct current generator of the present invention is as wind drive, the value of Va and the value of Qva are in inverse ratio, the value and Qia of Ia
Value be in inverse ratio, the value of the value of Pa and Qpa are in inverse ratio.
When alternating current generator of the present invention is as wind drive, the value of Ia and the value of Qia are in inverse ratio, the value and Qpa of Pa
Value be in inverse ratio.
The present invention has the advantages that not needing to add extra detection device in method of the invention, fresh air system is reduced
System purchase and installation cost；Simultaneously, according to the specification of different strainers, by electric current, the tune of the strainer in the process of running
Fast voltage and power signal associate with the weight parameter of strainer, and construct corresponding functional relation；So that strainer is being transported
During row, according to obtained electric current, speed electric or power signal, the weight parameter of strainer can be directly obtained, by this
Weight parameter and the ultimate load of strainer compare, and judge whether strainer needs replacing, and the data are the most accurate.
It under normal circumstances, is whole by the associated strainer weight parameter of the electric current, speed electric or power signal that measure
When being greater than or being largely greater than the ultimate load of strainer, strainer just can be carried out replacement operation；But when wherein one group of data
When obtained strainer weight is greater than ultimate load, in order to avoid strainer excessive load, operator can directly be carried out
Replacement.More preferably function is for it, and when three is the optimum load amount for reaching strainer, the reality of strainer can directly be calculated
Border load capacity F, the data are percentages show, can be convenient the loading condition that operator directly judges strainer, soon
Before reaching ultimate load, reminds, be convenient for changing in time.
