Description
Technical field
This utility model relates to a kind of control system, particularly relates to a kind of control system for two fans parallel connection ventilation occasion, belongs to HVAC mechanical field.
Background technology
In actual applications, it will usually use two fans system, such as the occasion important at some, blower fan installation and operation the most in parallel is in same system, all the more so when especially requiring Wind Volume.But owing to every Fans air quantity in parallel is not identical, the meeting irregular change because the external environment such as temperature, pipeline trend changes of unbalanced stream condition, that causes that blower fan is interrupted has load and non-loaded, the blower fan of parallel running can be caused to be in surge area and cause fan operation unstable.
Utility model content
For overcoming drawbacks described above, this utility model aims to provide and a kind of can be adjusted the airflow pressure of two Fans in real time, it is ensured that the control system of two Fans balance movements.
nullFor reaching above-mentioned purpose，The technical solution adopted in the utility model is: a kind of two fans control system in parallel，Including the blower fan one being mounted side by side and blower fan two，Described blower fan one is respectively equipped with Electric air valve one and Electric air valve two with the air outlet of blower fan two，Described blower fan one is connected to a branch road airduct one and branch road airduct two with the air outlet of blower fan two，Described branch road airduct one and branch road airduct two are connected respectively to air main by a three way cock，An effusion meter one and effusion meter two it is respectively equipped with on described branch road airduct one and branch road airduct two，Described effusion meter one and effusion meter two are connected with a digital signal processor one and digital signal processor binary signal respectively，Described digital signal processor one and digital signal processor two are signally attached to a signal contrast processor respectively，Described signal contrast processor and control centre's signal connect，Described control centre is connected with Electric air valve one and Electric air valve binary signal respectively.
Have employed two fans control system in parallel of the present utility model, respectively the flow of two Fans is measured in real time by effusion meter, and send a signal to signal processor in real time, pass through signal contrast, adjust the Electric air valve of two Fans in real time, make two Fans be in same operating mode all the time, prevent from, because what air quantity imbalance caused tacks and surge, making parallel fan even running.

Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of two fans control system in parallel, including the blower fan 1 being mounted side by side and blower fan 22, described blower fan 1 is respectively equipped with Electric air valve 1 and Electric air valve 2 12 with the air outlet of blower fan 22, described blower fan 1 is connected to a branch road airduct 1 and branch road airduct 24 with the air outlet of blower fan 22, described branch road airduct 1 and branch road airduct 24 are connected respectively to air main 5 by a three way cock, by regulation Electric air valve 1 and Electric air valve 2 12, blower fan 1 and the air output of blower fan 22 can be regulated, in sum, basically identical with the structure of existing conventional parallel two fans system.
The innovative point of two fans control system in parallel described in the utility model essentially consists in and is respectively equipped with an effusion meter 1 and effusion meter 27 on branch road airduct 1 and branch road airduct 24, described effusion meter 1 and effusion meter 27 are connected with a digital signal processor 1 and digital signal processor 29 signal respectively, described digital signal processor 1 and digital signal processor 29 are signally attached to a signal contrast processor 10 respectively, described signal contrast processor 10 is connected with control centre 13 signal, described control centre 13 is connected with Electric air valve 1 and Electric air valve 2 12 signal respectively.
Embodiment: when operating, in real time the air quantity of blower fan 1 and blower fan 22 is measured respectively by effusion meter 1 and effusion meter 27, and it is real-time transmitted to digital signal processor 1 and digital signal processor 29 respectively, after the analogue signal of digital signal processor 1 and 29 effusion meters 1 of digital signal processor and effusion meter 27 carries out being converted to the signal of 4-20mA, it is sent to signal contrast processor 10, control centre 13 is sent instructions to again after signal contrast processor 10 contrasts, Electric air valve 1 and Electric air valve 2 12 is issued instructions to by control centre 13, by Electric air valve 1 and the adjustment of Electric air valve 2 12, the air quantity in branch road airduct 1 and branch road airduct 24 is made to tend to balance.Specifically when the air quantity recording branch road airduct 1 is more than the air quantity of branch road airduct 24, control centre 13 issues instructions to Electric air valve 1 and Electric air valve 2 12, Electric air valve 1 is made suitably to turn down, Electric air valve 2 12 is suitably opened greatly, until branch road airduct 1 is consistent with the air quantity of branch road airduct 24, the big amount that suitably turns down and open of Electric air valve 1 and Electric air valve 2 12 is optimized test in advance, and input control centre 13, both the air balance in branch road airduct 1 and branch road airduct 24 had been made, also make blower fan 1 and blower fan 22 be near optimal working point simultaneously.
