Show lamp 111, the different colours shown by the warning lamp 111 can help operator to confirm the resistance detection point of filter 107
Whether whether analysis system be qualified products in the filter 107 for working normally and determining to detect.
In order to introduce a kind of resistance testing and analysis system of air filter provided in an embodiment of the present invention in more detail, with
The lower working method for introducing the resistance testing and analysis system.
Specifically, comprise the following steps：
Step 101, the first air passage flow in the air passage is obtained by the flow measuring meter being arranged on air passage, according to
First air passage flow-rate adjustment is arranged on the working frequency of the wind turbine of duct outlet；
Step 102, the first duct pressure in the air passage is obtained by the pressure difference meter being arranged on the air passage；
Step 103, after air filter being set on detection platform, the micro-pressure-difference being arranged on the air passage is passed through
Meter obtains the second duct pressure in the air passage；
Step 104, according to first duct pressure and second duct pressure, the pressure of the air filter is judged
Whether difference meets regulation.
In a step 101, simply individually wind turbine is allowed to work there are no air filter is set on detection platform, and
And in blower fan work, PLC controller obtains the first air passage flow in air passage according to flow measuring meter, to adjust wind turbine
Working frequency.
It needs, in practical applications, the working frequency of wind turbine needs and air filter match.
In the embodiment of the present invention, specific restriction is not done to the working frequency of wind turbine.
In a step 102, it is necessary to according to the pressure difference meter being arranged in air passage after the working frequency of wind turbine is regulated
To determine the duct pressure value in air passage.It in embodiments of the present invention, can be by micro-pressure-difference in order to accurate duct pressure value
It counts the duct pressure value measured to be counted, then according to statistical value, determines a more accurately duct pressure value.
Specifically, pressure difference meter is electrically connected with PLC control system, can set micro-pressure-difference by setting PLC control system
The picking rate of meter, multiple duct pressures so as to collect pressure difference meter within the period of setting carry out average
Change, so as to using the average value of multiple duct pressures as the first duct pressure value.
In embodiments of the present invention, the picking rate of pressure difference meter can reach 3 milliseconds/1 time.Further, setting
In time, 60 groups of duct pressures can be gathered, so as to which the 60 groups of duct pressures that will be collected carry out equalization.Implement in the present invention
In example, the specific group number of acquisition duct pressure is not limited.
In step 103, after the first duct pressure is determined, air filter can be arranged on detection platform,
Here, no details will be provided for the concrete structure of setting and detection platform to air filter.
After air filter is arranged on detection platform, the wind is obtained by the pressure difference meter being arranged on air passage
The second duct pressure in road.Second duct pressure is by the duct pressure after air filter.
It should be noted that in embodiments of the present invention, in order to distinguish set on detection platform air filter and
When being not provided with air filter, different pressure value in air passage, will on detection platform there are no set air filter, wind turbine
The duct pressure that the pressure difference meter multi collect being arranged on during work in air passage arrives determines a duct pressure value after carrying out average
It is determined as the first duct pressure；And after setting air filter on detection platform, when blower fan work, is arranged in air passage
The duct pressure that collects of pressure difference meter be determined as the second duct pressure.
At step 104, the second duct pressure and predetermined first that PLC controller is got according to pressure difference meter
Duct pressure compares two pressure, may thereby determine that whether the air filter is qualified.
Specifically, when the difference of the first duct pressure and the second duct pressure is unsatisfactory for default range of pressure values, then
It determines that the pressure difference of air filter is against regulation, then sends alarm signal to the warning lamp electrically connected with PLC control system,
So that warning lamp opens warning color.When the difference of the first duct pressure and the second duct pressure meets default range of pressure values
When, it determines that the pressure difference of air filter meets regulation, is then sent to the warning lamp electrically connected with PLC controller and open normal letter
Number, so that warning lamp opens color when working normally.
In useful application, default range of pressure values is the model and wind turbine according to air filter to be detected
What working frequency determined, in embodiments of the present invention, the definite method of default range of pressure values is not done it is specifically defined, together
When, default range of pressure values is not done yet specifically defined.
It should be noted that in embodiments of the present invention, warning lamp warning color and normal work color are not done specifically
Restriction.
When PLC control system compares the first duct pressure and the second duct pressure, PLC control system is by first
Duct pressure and the PC computer ends that are electrically connected as PLC control system of the second duct pressure transmission, PC computer ends are according to receiving
Multiple first duct pressures and multiple second duct pressures, above-mentioned data are counted, then by statistical result according to setting
Fixed form is shown.
Pass through above-mentioned statistics, it may be determined that the qualification rate of the air filter for being currently generated or detecting and defective products
Quantity.
Further, the qualification rate of the air filter of above-mentioned statistics, the detection data of each air filter, can
Mobile phone either ipad tablet computers or laptop computer are sent to by network mode, so as to carry out remote monitoring detection
Data and the condition of production.
In conclusion an embodiment of the present invention provides a kind of resistance testing and analysis system of air filter, filter dresses
