In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is to provide a kind of weldering fume purifier fan intelligent control system, comprise first control system of opening for realizing blower fan or closing, and for regulating the second control system of rotation speed of fan in real time according to electric welding machine curent change, wherein
First control system, comprise the electric current induction module for detecting electric welding machine current signal, and the PLC control module to be connected with described electric current induction module, the electric welding machine current signal that a described PLC control module detects according to described electric current induction module, controls unlatching or the closedown of blower fan;
Second control system, comprise the electric current identification module for detecting electric welding machine current changing signal, the described current changing signal that described electric current identification module is detected transfers to signal analyse block, described signal analyse block is according to the adjusted signal of described current changing signal and transfer to the 2nd PLC control module, and described 2nd PLC control module controls frequency control of motor speed module according to described regulated signal and carries out rotational speed regulation to blower fan.
In such scheme, also comprise the control panel being arranged on and controlling on weldering fume purifier and for manually-operable.
In such scheme, also comprise and to be arranged on weldering fume purifier and for the knob of manual auxiliary adjustment rotation speed of fan.
Native system, the intelligent opening welding fume purifier can be realized by the first control system, close, namely opened or shut-off circuit by influence electricity welding current, thus realize the function of automatically opening or closing blower fan, play certain energy-conserving action, that is when electric welding machine is started working time, native system senses that electric current is also started working, same stops along with the closedown of electric welding machine, make the energy-conservation facility of use of welding fume purifier, simultaneously, the intelligent frequency-conversion that can realize welding rotation speed of fan in fume purifier by the second control system regulates, namely when in electric welding machine, operating current changes time, blower fan in weldering fume purifier realizes frequency conversion rotational speed regulation with this curent change.
The utility model, adopt weldering fume purifier fan intelligent control system, can not only the unlatching of intelligent control weldering fume purifier blower fan or closedown, fan intelligent frequency conversion rotational speed regulation can also be realized according to the operating current change of the electric welding machine connected, the output power of effective change blower fan and air quantity, while the working life extending blower fan, also reduce energy consumption greatly, and, this Control system architecture is simple, easy to use, versatility is good, can be applied on all weldering fume purifiers.
