Air volume system control is very important for the ventilation system of electronic clean engineering. An electronic air volume regulating valve is installed on each fume hood, and its control switch and frequency conversion control system and fan linkage can realize the control of a single or multiple ventilation equipment under different working conditions. The electronic purification project of Hejie technology generally uses the air volume regulating valve, which has the obvious adjustable Angle of the electronic air volume regulating valve, and has the memory function. Specific with Hejie technology to understand how to control the ventilation system!

Hejie Technology electronic purification project will be based on customer requirements, the production of constant air volume system air valve and fan integral interlock, to achieve the orderly flow of air flow, balance the system air volume, to avoid air flow, reverse flow. Variable air volume adjustment valve adopts digital display adjustable Angle of the air valve, and has memory function (that is, can remember the adjustment Angle, the next time open is still adjusted to the design Angle), to achieve low consumption of engineering operation support and guarantee.

Static pressure sensor automatic frequency conversion control (or PLC programming control) is generally used in the constant air volume system of electronic clean engineering. The static pressure sensor automatic frequency conversion control can be converted into 0-10v voltage signal input to the frequency converter according to the change in the number of open ventilation equipment, so as to automatically adjust the fan frequency. The exhaust air volume of the fan is matched with the actual required exhaust air volume, so as to ensure the exhaust effect, and achieve the effect of saving energy and noise.
